Dear Professor Shapiro,

Thanks for your message.  I will go ahead and arrange a talk for you on
August 26, and schedule appointments for you to meet people in the Department
for that day.  I will make reservation of hotels for you for the nights of
August 25 and 26.  Please let me know your arrival time if you come by plane,
so that I can meet you at the airport (San Jose or San Francisco will be good).
If you come by car, I will send you a local map.

Please let me know if there is any additional arrangements I can make for
you.  I am looking forward to seeing you.

Sincerely,

Andrew C. Yao
Professor

John,

These dates (July 23-24) are fine with us.  We will make the usual reservations
(unless you tell us that you want to change hotels or something).

I suggest that we wait until you arrive to discuss the wording of the 
contract.  I have asked Dick Hill to go over it with you;  I will 
get into the act when and if it is necessary.  

We look forward to seeing you.

Geee !
	What kind of twisted, self-righteous reasoning is that in which
playing a "fair" policeman in foreign policy is more appropriate than 
building alliances?
	First, the only fairness you can expect from U.S. foreign policy is
obviously (could it be different ??!!) one in which the U.S. is fair to its
own interests.... It is naive to expect anything else. 
	Second, building alliances is already part and parcel of the western
policeman role the U.S. has taken on since WWII. I'm not talking only about
alliances with nations; there were and there are alliances with guerrilla
movements ( counter-revolutionaries in Nicaragua,  Unita in Angola, etc),
military and oligarchy thugs/dictators ( Pinochet,  Somoza, Duvallier, 
and tens of lesser known ), even nazi fugitives who became allied spies after
1945.
	Your proposal of supporting militias in Lebanon is not anything new. 
Israel has done it and it is much  more convenient for the U.S. to act through
a client regional power. At least Israel can claim legitimacy for invading
neighboring countries, and even imprisioning local civilian resistants.
Some type of fairness isn't it?
Sergio

Why is it so hard for you to understand that what is needed is not to
defeat terrorrists. When there are terrorists its because of something.
The idea is to behave in such a way that you don't create resentments.
What those people want is no interference with their struggles. If
the U.S. is an ally of what these people consider is an enemy ( Israel ),
then there will be resentment against the U.S. If the U.S. threatens
the Nicaraguan government, there will be resentment against the U.S.
in that region too. Why not leave people top solve their local crisis
without any involvement of any superpower? Everyone has to mind his/her
own business and not be nosing around in other's affairs. Terror is
the consequence of desperation against someone you cannot fight
directly. They feel like that because something caused it.

A more interesting function (!!!!!!) for proving corrrect and ...

(defun zip (n &optional (c 0))
  (cond ((= 1 n) (print c))
        ((> n 1) (let ((random (random n)))
                   (zip (- n random) (+ c random))
                   (zip random c))) ))

What does it do and why do it this way!!!!!  (without running it of course!!!)
1. "&optional (c 0)" means if you dont give a value to "c" then its becomes 0.
2. random is used bath as a variable and a function name.
3. random is an integer valued function that returns a value between
   0 and n-1 (inclusive)

Fine.   Now we have reduced the problem of ending terrorism to the problem of
doing something which neither Socrates nor Jesus nor Gandhi nor Michael Jackson
(much less Jesse Jackson) was able to do.   I feel better already.

"I will claim that our policy in Lebanon made attempts to be fair at the
cost of hindering our partial ally Israel from accomplishing its objectives.
It seems to me that this was a mistake."

I agree, and would look for a stronger word than "mistake."  I think the
U.S. should have publicly made lots of noises about how terrible
Israel's behavior was and how we wanted to get in there and play
peace-keeper, but privately assured Israel that no severe reprisals would
be forthcoming. And while we would negotiate furiously, somehow we would
never quite work out a satisfactory deal that involved our military
participation.  Thus our real role would be limited to acting as moderator
among mid-east factions, but letting them work out their own settlement
(and keep fighting if they couldn't).  Also, we would stare at Russia,
to keep them from getting any funny ideas.

The rhetorical part of my suggestion reminds me of that game for which you
proposed the name "So Long, Sucker."

I think it would be nice if a sail program took care of getting things
in step with the rest of the community, instead of asking the
community to adjust to sail's idiosyncrasy.  Specifically, whatever
program exports mail from sail to other machines should replace
OTHER-BBOARDS@SAIL by SU-BBOARDS@SCORE whenever it occurs in the

I claim that the problem is either with the SAIL mail handler or with the REPLY
command in MM, most likely the former.   Another way of putting this is that,
if SAIL users value their ability to put things on their own BBoard which don't
appear on anyone else's, then they should not beef too loudly when, as a
side-effect, the rest of the world has the ability to put messages on all
BBoards except SAIL's.

Of course, if it were really important that the whole world see my message, I
might bother to edit the TO field.   But it is not that important.

I'm still not clear when our proposed meeting is on.  I got a 
letter from your secretary a couple of days ago suggesting Tuesday 23rd.
This would be fine with me except your later e-mail message says
that you can only make Monday. Can you please let me know before Tuesday
what is most convenient for you. My current arrangements are to give a
seminar at IBM San Jose at 2pm on Monday 22nd. That leaves either very
early meeting Monday morning or very late Monday afternoon for a meeting.
Obviously I would prefer the Tuesday if it can be arranged.

Here's the plan:

We all (minus Matt) will converge at Yuen Yung 
	[415 323-7759, 639 Santa Cruz Avenue, Menlo Park 
	 (near where El Camino meets Santa Cruz; around the corner from Su Hong)]
Tuesday night at 6PM.
*Those of you with recognizable cars should not park too nearby.*

Matt and Steve K will arrive at about 6:30, to meet a "business associate".
Surprise!

[Co-conspirator Mike is vice-president in change of specifics of this
surprise.  He may have further details...]

- Please RSVP, to help us get a head count.
	Address this, as well as any questions, to both Mike and me.
	The heading should be something like  "Private msg".

- Tell anyone else you think might be interested.
	In particular, I didn't know anyone on his baseball team.

- Any ideas about trickets to present him?
	Perhaps a cane, to indicate his advance age?
	Or Grecian formula <whatever>, to help dye his whiting hair, or ...

- Remember, Matt is very crafty.  For this surprise to be successful,
	we all must be very careful.

See you tommorrow,

I've often heard people refer to the rampant internal inconsistencies

just "know they're there."
If you really do know of such inconsistencies, I'd be very interested in

Subject: reply to your comments on my work

I have finally had a chance to go over my paper in the light of your
criticisms.  It seems to me that some of your criticisms are based on
an incomplete understanding of my system (in some cases the incomplete
understanding was mine); in any case I believe these objections will 
not arise after the exposition is improved.  One of your objections 
was more fundamental, namely that the system does not provide a way to 
interrupt execution when new input is provided, decide if replanning is 
necessary, and start up again.  That will have to be left for the future.

I shall not ask you to look at another draft, but rather
just say a few words about your criticisms here.

1.  You say that my rules are not non-monotonic because I have to list
all the exceptions in advance.  Actually, I only list all the 
KNOWN exceptions, along with what to do in the exceptional cases.
If we happen upon a previously unknown exception, something will go
wrong and we won't know what to do.  It is true that something beyond
my system would be required to make intelligent modifications to the 
rules at that point, creating a new exception.  But so long as things
do NOT go wrong, you don't even check the exceptions, so it doesn't
matter if you have listed them all or even know them all, which I still
think is the essence of non-monotonic reasoning.  You say, "as long as
all the exceptions have to be built into the rules in advance, there is 
no significant difference from putting the negations in the positive part".
Declaratively, of course that is so.  Procedurally, it is not so.

2.  You say, "quite different programs can use the same facts", and
object to my saying that a control structure must be specified.  There
is nothing in my system to prevent the same facts from being used in 
different ways in different situations.  In fact, that would naturally
happen!  You also mention "we can have facts that we don't as yet have
any way of using".  While that doesn't arise in any of the examples I 
have considered so far, there's nothing in the sytem that prevents it
from having a bunch of apparently irrelevant rules or facts, which might
be kept at the highest level of generality (the "operating situation")
for lack of a better place to put them, and thus inherited by every
subsituation, where they might eventually prove useful.  That seems
quite natural to me.

3.  The fanatical Mormon who would rather die than drink coffee.  
The rule in question may be:

     if the poison was barbituates etc.;
     then have the victim drink coffee. 

This rule should be written

     if the poison was barbituates etc.;
     then have the victim drink coffee or tea;
     except  if true then true.

The "if true then true" clause could be read "continue".  It has the 
effect of saying that failure of this rule should not cause failure of
the whole rule in whose then-part it occurs.  Suppose the Mormon
refuses the coffee.  Then the procedure "have the victim drink coffee"
fails.  Now the except clause comes into play.  We check its if-part,
which is true, and so we fire the then-part, which is true, i.e. 
automatic success.  Hence the whole rule succeeds and we can go on,
despite the refusal of the coffee.  

This is an interesting feature of if-then-except rules, that it 
provides a natural mechanism for marking those rules whose execution
is not essential to the overall plan.

4.  Unification and reasoning about a situation with a variable.
Nothing in my system forbids the planning program from working with
variables.  However, you can't actually DO the situation until you
are IN it.  You might plan to tip the waiter without knowing who it is,
but you can't actually tip him until you have identified him.  
I believe that my present draft is weak on the distinction between
reasoning about actions and actually performing them.  I agree 100%
with what you say about using predicates in PROLOG to make the program act;
it depends on fortuitious parallelism.  I am not satisfied either with
my system or anyone else's on the connection between reasoning and 
action.  

5.  Scripts vs. situations.  Yes, complaining and going to the men's room
are subsituations.  There is a script for going to the men's room and 
one could write the rules for it  (the entry conditions are the most 
subtle part).  The situation of complaining is probably not a script,
since the possible developments are not too predictable.  If it is
not a script, then including it as a subsituation of the restaurant
situation would mean that the entire restaurant situation no longer meets
the definition of a script, which requires that all subsituations also
be scripts.  But since that subsituation would rarely arise, in most
instances an execution of the restaurant situation would be script-like.
This is an interesting illustration of the fact that there is actually
a continuum of different sorts of situations, with the completely
determinate "scripts" at one end, and more varied situations like
chess at the other.

6.  Planning and building towers of blocks.  I presume you refer to 
the example on p. 534 of the Handbook of AI, vol. 3.  I shall treat that
example in detail in my paper; I think my system can handle it nicely, but
I don't have it written out at present.

Ed, John

Senator glenn has arranged to visit stanford on 27 august
to learn about darpa efforts and other
activities on the campus. Dick reynolds has been handling
the visit directly with jim gibbons and jim meindl
and asked me to recommend an agenda for the efforts
that we have been supporting. Im working
the schedule with nils on behalf of all the departmental
activities, but wanted to alert ythe two of you directly
so you'ld have at least a month lead time. We werent
involved in picking the dates so im merely trying to
accomodate the senators expressed wishes.

My understanding is that he plans only to visit cal tech
and stanford (of the universtiies) and perhaps livermore.

Ill send a draft agenda to nils to handle coordination.

You asked why a plan should be a sequence of rules instead of allowing
conditionals.  But it does allow conditionals, since remember that
according to my definition of rules we can have rules like
   if A then if B then C
             if D then E
             if F then if G then H 
                       if I then J

Some thoughts that came to mind in this connection:
 
	(1) I find the statement "program x  is unverifiable"
somewhat incredible -- it's been 200 years after the days of David Hume.
His position on mysticism (which is what this statement really represents)
of this sort is worth quoting.
	(2) There is the perhaps more general issue of "loss of nerve"
that Bronowski et al talked about.

Nils,

Darpa was asked by senator glenns office to arrange a visit to
stanford and cal tech in late august and they suggested the dates
of fri 23 aug for cal tech and tues 27 aug for stanford.  Dick
Reynolds of Darpa/DSO has been given the overall responsibility
for handling the arrangements here at darpa.  Please see his
attached note to Jim Gibbons and Jim Meindl.

Ive been asked to put together the agenda for 115 minutes of
darpa/ipto presentations including 5 minutes for me to overview
what were not formally presenting by the stanford faculty.

This is over a month away, but i realize that vacations, summer
plans or other schedule conflicts could still cause problems.  In
any event, id appreciate it if you could determine exactly who
can be available to talk to senator glenn on the 27th.  I even
recommend rearranging plans, if they can be easily rearranged.
If they cant, well we will have to work around it somehow.

Jim Gibbons or Meindl may have talked to you about this already.
In any event, ill send along a draft agenda for you to comment on
in my next message.  Feel free to suggest an alternate
arrangement if you think a different cut would be more effective.

My strategy is to include the better speakers, more immediately
relevant research and biggest projects in roughly the inverse
oder i presented them.  I may have missed something.

Id appreciate your reactions.  bob

Bob, the Glenn schedule looks fine with me.  I would propose we have
Ed/Bruce give overviews of KSL projects; JohnMcC/Les Earnest a brief
presentation on the new QLISP project; Tom Binford on vision/robotics; I
give a short summary of the CSD in general.  About Hennessy/Meindl and
other outside of CSD work, I presume Gibbons/Meindl will coordinate this?
Anyway, I've marked the am of Aug 27 and am notifying appropriate others
in the department.  -Nils

Nils, Jim

Here is a first draft of an agenda for the Senator
Glenn visit on 27 August. Im not sure who is likely
to be available on that date - but im strting with
the assumption that schedules are rearrangeable, if necessary.

Heres how id apportion the 110 minutes that
Dick reynolds allotted for presentation of IPTO supported
activities on the campus. Those omitted from
formal presentation will be summarized by me in a five
minute introduction. 

Kahn - KB vlsi, Cooperating agents, Regular expression silicon compilation,
real-time analysis and modelling, distributed information theory
and vision (unless its covered in the robotics presentation).
- 5 minute summary only

Meindl - 30 minutes - Foundry automation/CIS re Fast Turnaround & integrated
			System aspects, MIPS & design tools (Hennessy results)

Feigenbaum - 25 Minutes - Knowledge Systems & Advanced Architecture

McCarthy  -  25 Minutes - Formal reasoning, Qlisp, logic programming
				benchmarking (gabriel results), adaptive storage 				structures (wiederhold results)

Ullman - 10 Minutes  - Parallel Computation

Luckham - 10 minutes - Ada Verification

Cheriton - 10 Minutes - Partitionable Systems


Id appreciate any comments or alternate suggestions, especially
if some of the packaging doesnt quite fit.

thanks

I have made tentative arrangements to hold our retreat at "The Family
Farm" in Woodside/Portola Valley.  Let's plan to start at 9am.  I'll
arrange to have a continental breakfast ready there.  We'll also
have lunch there.  Confirmation of that site and a map will be
available presently.  (I hope everyone has saved August 2 for this
momentous event.  That's a Friday.)

People might be thinking a bit about agenda items.  Here are some
possibilities:

Possible Agenda Topics
AI Faculty Retreat
Friday August 2, 1985
Place to be announced

*Long range plans for growth in AI.  Should we be looking for new AI
professors [including professors (research)]?  If so, in what sub-areas?
(Or, more concretely and therefore better, who is on our list of people
in AI that we should be trying to attact to Stanford? Please bring your
favorite list along.)

*Curriculum.  Is our current set of AI courses sufficient (even
necessary)?  What changes ought to be made?  Is our current scheme for
deciding who teaches what working?

*PhD advising.  I think that the workload of advising AI PhD students is
rather unevenly shared by the AI faculty at present.  Can or should
anything be done to remedy this?

*The AI Comprehensive and Qualifying Exams.  Are they doing what they
should be doing?

*What will be the impact, if any, of CSD's move into Engineering?

*What will be the impact of starting an undergraduate major?

*Can CSLI help the department better cover some areas of AI that we are
not now covering?

*Suppose there were such a thing as a "collaborometer" (which we could
use to measure how much Stanford AI people are collaborating).  Could we
benefit from more collaboration in our research? Less?  Or should we
↑throw the meter away?

* Organization: Some departments (such as E.E.) are internally organized
into "laboratories" which are mutually exclusive and exhaustive subsets
of the faculty in the department.  CSD's internal structure (if such it
can be called) is more complicated.  Some of the faculty do belong to
the Computer Systems Laboratory which acts as kind of standing committee
for appointments and curriculum matters in the systems area.  As the CSD
grows there may be reason to designate subsets of the faculty as "labs"
for purposes of splitting up the administrative workload of the
department.  Should there be some overarching AI Lab entity consisting
of all CSD AI professors?  [For example, here's a proposed model:
Analysis of Algorithms and MTC, Systems, AI and Robotics, and Scientific
Computing (incorporating numerical analysis).]  Such a subdivision is
compatible with an overlay of multidisciplinary "Centers."  Dividing CSD
in this way and organizing something called the AI Lab subdivision of
CSD need not have any impact on the continued thriving of such entities
as KSL (considered as a "Center"), CSLI, SIMA, CIS, etc., etc., ad
infinitum.

Waqar
-----------------------------------------------------------

This is a question about why logic was divided into 
"levels" - 1st order, 2nd order etc.

From what I remember from CS206, the problem was Russell's paradox i.e

H(P) <-- not P(H)    (  <-- means "defined as" )     (1)

created a paradox when one took P to be H. So it was
decided to eliminate this possibility by stipulating that
predicates of order k could take only predicates upto
order k-1 as arguments.

But couldnt the viewpoint be taken that this was a bad
definition of a predicate. You can write a contradiction in 
any language. I suppose that "good definitions" (those that
do not lead to contradictions) are possible in "mixed-order"
logic.

Consider the 1st order definition:

P(x) <-- not P(x)		(2)

What is the essential difference between (1) and (2)?
Is it that the contradiction is not "obvious" in (1).
But (2) can be made more nonobvious by trying to hide the
contradiction in an if-then-else for example.

    What's this I hear about Pournelle being zapped at MC for favoring SID?

I haven't been involved in this, but from what I hear, Pournelle has been
making coy references to how `important' he is as a result of having an
account on the arpanet (MC) in print (specifically in his Byte magazine
column).  Several people have told him that we consider it in bad taste to
discuss his access to things like the SF-LOVERS mailing list on the arpanet,
in print, and in public, because of the previous political flaps about
mis-use of the arpanet.  He hasn't taken the hint.  Finally, after the Nth
time of him ignoring it, we told him he would either cool it or lose his
account.  His response was juvenile, at best, in effect daring us to do it.

Who is Sid?

I am sending this memo to various people that I know have been closely
involved with the ACM Symposia on LISP and Functional Programming.
Non-recipients should not be offended, but are also invited to respond.
	In 1984 in Austin there was discussion about making L&FP an
annual meeting.  Dick Gabriel is making some changes to the style of the
1986 meeting, which might have affected that sentiment.
Nevertheless, we should now consider whether or not to propose a 1987 L&FP.

1980 Lisp Conference in Palo Alto venued with AAAI
	1981 ACM Functional Programming Lanuguages and Architectures,
		in Portsmouth, New Hampshire
1982 ACM L&FP in Pittsburgh venued with AAAI
1984 ACM L&FP in Austin venued with AAAI
	1985 IFIP Functional Programming Lanuguages and Architectures,
		in Nancy, France
1986 ACM L&FP in Boston independently scheduled


	I have added in the indented information, because the latter was
originally scheduled for 1984, but graciously postponed by its organizers to
avoid 1985 L&FP conflict.  Thus, I argued in Austin against going annual with
L&FP  before 1986 so that we would return their courtesy.  
	Also relevant here is the long-hoped-for British L&FP meeting.
If the next meeting is to be in Britain, then 1988 may be better than
1987, because the 1987 January ACM POPL meeting is definitely to be in Europe.
There is a significant intersection of the two audiences.
	After all this, the question is: "Should we find chairs for a 1987
L&FP meeting?"  An affirmative answer requires action in the next six months,
because the TechnicalMeetingRequestForm must be prepared BEFORE the
1986 meeting.  The decision to proceed with planning may wait until after
the September meeting in Nancy, but I would appreciate an informal reaction
before then.

Here's a possible additional paragraph:

 
	It seems to us that the issue of the scientific merit 
of the SDI initiative has been confused with its 
political desirability. We look forward to the time
when the technical issues brought up can
be discussed with the same professional detachment as any
other challenging "leading edge" research in computer science.
To simply claim that large scale program verification is 
undoable is to consign major parts of computer science to the
realm of mysticism. This runs counter to the basic principles
of scientific inquiry, on which our western culture is built
and nourished ever since the days of Rene Descartes and David Hume.

In-Reply-To: Message from "John McCarthy <JMC@SU-AI.ARPA>" of Wed 17 Jul 85 19:05:00-PDT

	I'm a linguist and I've never heard the myth that authorities
can't improve language by prescribing improved usage. There are two
related beliefs, however, which taken together mean it is not very often
that this will work. One is that the kinds of "improvements" envisaged
by prescriptive authorities are often matters of no functional significance.
The other is the fact that it is very hard to get people to observe
prescriptive rules. I can think of examples where prescriptive changes
have taken effect and have resulted in improvement (e.g. reduction
in ambiguity). One would be the Japanese orthographic reform after the
Second World War that resulted, for example, in the elimination of
the ambiguity that had previously existed between the verbs ikiru "to
live" and naru "be ripe". This particular rule seems to be obeyed. But
other standardizations that were part of the same reform result
in no improvement (e.g. the rule governing the choice of characters
for writing various derived forms of the verb "begin"), and other aspects
of the orthographic reform are
ignored except in official documents (e.g. the limitation to a standard
list of 1900 characters). So it seems to me that the "myth" is almost,
though not entirely, true.
	By the way, I am curious about the improvement putatively
wrought by Samuel Johnson. What was it, and how did he do it?
Was it by prescription, or was it by serving as a model?
I suspect that the latter is a much more effective means of
influencing language than the former.

Abstract:

	Random Polynomial Time is Equal to Slightly-random Polynomial Time.


An important goal of theoretical computer science is to capture
theoretically the notion of a *tractable* computational problem.  
It is currently well-accepted that a problem is tractable if there is a
polynomial time algorithm for it, having the ability of flipping a
fair coin at each step.  This formalization is theoretically
appealing, and captures important problems such as primality testing,
which are not known to be efficiently solvable without randomization.
However, it is beset with a difficulty: the available sources of
randomness such as Zener diodes, and Geiger counters are imperfect.
They do not output unbiased, independent coin-flips.  We introduce a
general model for such imperfect sources of randomness: the
"slightly-random source".  Determining the usefulness of such a
source is of theoretical as well as practical importance.  Consider
the class Slightly-random Polynomial Time (SR sub p ), the class of
functions computable in polynomial time using a slightly-random
source. ``Is R sub p = SR sub p?'', where R sub p is the class
of problems solvable in polynomial time, using a fair coin.  We give
an affirmative answer to this question.  Our result is constructive:
given an R sub p algorithm for a problem, we show how to obtain an
SR sub p algorithm for it.


The above result is surprising in view of the following theorem:
One Slightly-random source cannot be used to obtain even a single
random bit. Thus proving SR sub p = R sub p may be a step towards
answering the ``P = R sub p ?'' question. We can further show that
two independent slightly-random sources can be used to efficiently
obtain high quality random sequences.

I don't have much in the way of emailable description of NUSUM.  I still have some
reprints of the old Proc Nat Acad Sci paper, if Herb is as physically nearby as his
From: header suggests.  (Of course, somewhere in the bowels of Jacks Hall are the
archive tapes with the POX "galleys" of that paper!)

Perhaps he could use a transcript of some sample calls.  I could email a few of them,
which would involve MACSYMA's yucky teletypoid display typography, or maybe physmail
him some screen hardcopies that at least have Sigma signs and division bars.  I will
probably visit SU tomorrow anyway, so if Herb actually there, he should tell me where.

He seemed interested in the source code.  It has grown long and unreadable by virtue
of my last year's extension to mixed summands and to infinte sums and products of rational
functions.

These extensions are not yet being distributed by our Macsyma group, who may
wince at my randomly sending them out.  Mainly for lack of TeX (thru corporate idiocy),
I haven't written up any of the new stuff.  There are a couple of neat stunts involving
suppression of polygammas if at all possible, illegally rearranging conditionally
convergent series and then quantifying and redressing the error, and handling divergent
series in the exponents of constants in offsettingly divergent infinite products.

If Herb is handy to JMC, he could try to find a few slips of LGP output of selected
examples which I left between the pages of JMC's copy of Knopp's summation book when
I returned it.

Also, he says his Vaxoid macsyma is broken, so I don't know what he could do with the
source code except try to read it, which I'd guess is futile.

He *could* run it on JMC's 3600, except that the bureaucrats in SMI (Cambridge) are holding
up JMC's Rel 6 permission because they need paperwork sequestered by MLB.  (Maybe I can
unstick this crap when I see RN tomorrow.)

   We introduce a minimal model query evaluation procedure (MQEP) which, given
a database DB and a query Q, verifies whether there exists a minimal model of
DB in which Q is satisfied.
   In view of the fact that circumscription relative to DB implies a formula F
iff F is satisfied in all minimal models of DB, the procedure MQEP can be used
to evaluate queries in circumscriptive theories. Similarly, since the generalized
closed world assumption (GCWA) as defined by Minker can be viewed as a weak form
of circumscription, our procedure can also be used to evaluate queries under
the GCWA.
   When applied to a Horn database, the procedure MQEP coincides with Clark's
query evaluation procedure QEP.

implement the CWA). Second, some actions, such as pushing an object "next to"
something, do not allow us to give a complete description of the positions of
all objects after the event.

``Why aren't the nightingales singing this evening?''  I asked.
Savka turned slowly toward me.  His features were large but well
formed and expressive and gentle as a woman's.  He looked with 
kind, pensive eyes, first at the wood and then at the thicket, then
quietly took a little pipe from his pocket, put it to his lips, and
blew a few notes like a hen nightingale.  At once, as if answering his
call, a rail-bird ``chucked'' from the opposite shore.

``There goes a nightingale for you!''  laughed Savka.  ``Chuck-chuck!
chuck-chuck! as if it were jerking at a hook, and yet it thinks it
is singing!''

``I like those birds,'' I said.  ``Do you know that when the time comes
for migrating the rail doesn't fly but runs along the ground?  It only 
flies across rivers and the ocean and goes all the rest of the way
on foot.''
...They are hatched here and here they raise their young.  This is 
their native land, and they only fly away to escape being frozen to death.

I've forgotten what we did in that case, but I could rummage around to
try to find out.  I'm not sure we could give to STRIPS any problem with
the goal of having the robot go to a place described by geometric 
coordinates.  I think we avoided the problem by specifying places like
"next to this or that".  STRIPS always assumed that such a goal was
achievable, and the lower-level routines (during plan execution)
found a putative clear spot satisfying this description.  These lower-level
routines had a digitized map of a sort that noted all filled (that is,
inaccessible) areas. So, I think, if we gave the robot the goal of
getting next to a place entirely surrounded by a wall of blocks, I guess
STRIPS would just keep on planning to get inside, and the execution routine
would keep on failing to do so.  (As I write, this does begin to sound a
bit strange--so maybe I better try to remember it better.  By the way,
I wrote up a story about all of this from excerpts of old reports, etc.
in an SRI report called "Shakey the Robot."  My secy has copies if you don't.)


We might have had "an evaluable predicate" CLEARPATH as a precondition for
a STRIPS "goto."  CLEARPATH could have looked at the geometric map to see
if there was a clear path.  If there wasn't the operator couldn't be
invoked.  The geometric map involved a kind of CWA.  Any cell in the 
map that wasn't listed as explicitly "filled" was assumed to be empty.
Well, all of that was a long time ago.

	The bi-/semi- confusion has irked me as well.
	But on the other hand, most people in CS are guilty using
"mega-" to mean 2↑20 except when decimal digits to the right of a
decimal point can be expressed as a NYSE fraction.
	1 megabyte = 2↑20 bytes = 1,048,576 bytes
	1.5 megabytes = 1 1/2 megabytes = 1,572,864 bytes
	0.75 megabytes = 3/4 megabytes = 786,432 bytes
	1.1 megabytes = 1,100,000 bytes 
	8 megabytes = 2↑23 bytes = 8,388,608 bytes
	8.1 megabytes = 8,100,000
which implies (what all CS types understand intuitively) that
	8 megabytes > 8.1 megabytes.
No wonder the public accuses us of being obtuse!

I was trying to figure out, yesterday, why I wasn't happier about
passing the AI qual.  (One explanation is because I didn't pass it
last year, but I will ignore that for the sake of argument).  What I
noticed was that while I felt that I did better this year than last, I
didn't have any better idea of whether I had passed after this qual
than I did after last year's.  The point, I think, is that I had no
real idea of exactly what was to be covered, or what level of
competence was expected.  I have talked with a few other students who
took the qual recently, and they had the same feeling.  If the qual
is, in fact, intended to test our preparation to do research, then it
is important that the faculty communicate with us what knowledge is
necessary to be prepared for research.  The current qual system is
closer to providing one bit of feedback per year.  (Actually, Bruce's
comments to me last year were very helpful).  The AI literature is
large and not as well structured as one would like.  Especially as the
AI Handbook starts to become outdated, it is important for students to
have more guidance.

John,
Thank your for your note.  As you know from your role as student
bureaucrat, I am in charge of a committee next fall to review the entire
situation of comps, quals, etc. for PhD students.  I plan to begin the
process by actively soliciting student comments, like yours. As you may
not know, there is a plan for the AI faculty to have a retreat this summer
to discuss a variety of issues. I think one of the major ones should be
the whole question of how we educate AI students.  This includes more
coherent qual requirements and also the question of what kind of
additional courses, meetings, or something would get students to do deeper
thinking and synthesis of what they have learned, rather than amassing
details at the handbook level and then diving into a sub-specialty area.
The quals this year convinced me there is a real lack.  If you have any
further thoughts on this, please come talk or send around a note.  --t

John,
  I largely agree with Terry.  But there is value, too, in knowing the
facts & details at the Handbook level.  As former-President (of Stanford)
Sterling once said, "You can't think about the facts unless you can
remember them".
  But we also expect some synthesis, some thinking to integrate the
details into a larger picture.  What are the issues, what are the
good ideas, where are things going?

Thank you, Terry and Bruce, for the prompt and encouraging responses.
I am leaving tommorrow for a summer at Bell Labs, so I won't drop by.
However, I would like to follow events by electronic mail.  Also,
Peter Karp has set up a mailing list, AIPS@SU-AIMVAX, of students
interested in AI.  It was set up to improve communication among AI
students, but it would also be a convenient way to solicit student
opinion before or after the faculty retreat.

In the mean time, I'll throw in a few bits of clarification.  For me,
at least, understanding some of the issues is to some extent a
pre-requisite for remembering the details.  Otherwise there is no
framework by which to remember the details.  This certainly applies
for any details remembered after the day of the qual.  But getting an
understanding that goes beyond details means reading papers.  Given
the combined thickness of even just the IJCAI's, AAAI's, and Machine
Intelligence's, it is important to have guidance toward papers which
are clear, readable, and make important points.  This is the kind of
information that one solicits from collegues after then have gone to a
conference by asking, "What were the good papers?"  The Webber&Nilsson
collection provides a start, but isn't comprehensive.  A concise list
of quality papers, with perhaps an abstract for each, putting it in
historical perspective, would be extremely useful.

Some of AI culture consists of a collection of techniques, and these
can be found in papers.  But much of AI culture also consists of
lessons learned about when techniques work, and what their limits are.
This knowledge, in turn, has a major impact on where research is
proceeding.  In the expert systems area, there has been quite a bit of
discussion (sometimes heated) of where the current techniques do and
don't work, but I have found it more difficult to find such
discussions in other areas.  The tendency is for papers to say "See,
I've solved this problem."  If we, as students, are to avoid repeating
the mistakes of the past, it is important to know what has been tried
and failed, and why, as well as what has succeeded.  I see no way by
which the department currently provides an effective way to learn this
kind of information.  229B, as it is currently constituted, certainly
doesn't, except when guest lecturers provide it.

PS. I picked the four of you as recipients of my original message
because I thought you might be interested and because I remembered
your electronic addresses.  I would be happy to have these messages

@greeting(Dear Sir:)
A number of scientists have recently claimed that the computer  
programs needed to realize the Strategic Defense Initiative (SDI) are impossible
to make reliable, and therefore the project must be abandoned.  As far as I can 
see, these scientists are speaking beyond their competence in order to lend 
support to the anti-SDI cause.

The computing arguments they have raised are of a general character.  The
Fletcher report on ballistic missiles defense says a program with 6 to 10
million instructions will be required.* This would indeed be a very large
program. But that doesn't justify the assertion by these scientists that
the program cannot be written, and if written, could not be verified.
Even larger programs have been written and put into immediate successful
use.

For example, the program put into use by AT&T when the nation changed over to
electronic switching has 50 million lines of code.  Furthermore, it has
14,000 interconnections between nodes, compared to an estimated 4500
interconnections in the SDI program.

In other words, the telephone program is bigger and in many respects more
complex than SDI requirements.  Yet the program worked well from the
moment it was put into operation.

The argument against SDI continues by asserting that the only way to make the
program reliable is to have a nuclear war in order to test all parts of it.  This
is a mistake.  Many present programs are designed to deal with emergencies too
dangerous or expensive to allow them to happen for test purposes.  Yet techniques
are available to make these programs reliable.  The mammoth AT&T program worked 
when it was turned on although it had never been tested in "battle". 

These techniques for checking large programs include the following. 
First mathematical techniques exist for proving parts of a program
correct and checking those proofs by computer.
Second,
simulated battle conditions can be created that are even more complex and  more
stressing than a real attack.

*Report of the Study on Eliminating the Threat Posed by Nuclear Ballistic Missiles,
Volume 5 (Battle Management, Communications and Data Processing), p. 43.

@newpage
My conclusion, based on 35 years of research in computing and artificial
intelligence, is that
those who oppose Strategic Defense or "Star Wars" have no basis in computer science
for predicting its failure.  They must rely on the general principle, "Where
there is a will to fail, obstacles can always be found."

Like the other scientific and engineering problems associated with SDI,
the computer problems are likely to be challenging.

John, if your letter will be at all widely distributed (as it must be in
order to be maximally effective), it is probably a sub-optimal choice to
affix your home telephone number to it, both because you'll miss daytime
calls which you might want to answer when you're at your office and
because you may get calls at night at your home which you'll wish your
secretary had screened. I suggest that you use your office phone number
(below with your home address) and put "(day)" after it.  This way, you
can get the inevitable crank mail at your home, and your CSD secretary
will defend you from the crank phone calls.  Lowell]

I have received response to the effect that some of you have not yet
received your maps. So, here are some verbal directions.

Take Sand Hill Road exit west off I-280 and stay on it until it turns into
Portola Road south. The exit for "Family Farm" is 1 mile south of the
Searsville exit. (Do NOT take the "Family Farm Road" exit which is 3/10
of a mile south of the Searsville exit.) The entrance to Family Farm is
designated by two stone posts and a sign on the left side indicating that
it is NOT "Family Farm Road". (It is, however, the "Family Farm" road.)
Drive in past the area designated "parking" until the road turns to the
left. Don't turn left, but park in the grassy field near the woodpiles
and walk two blocks searching for Cabin 46.

   The Closed World Assumption for predicates P1,...,Pn in a database DB
states that the information about these predicates given in DB is complete
in the sense that it consists of all and only the relevant facts. There
are several approaches to the formalization of this assumption. The two
most interesting ones are McCarthy's circumscription, or the minimal model
approach, and generalizations of Reiter's CWA  -- a proof-theoretic approach.
We investigate the relations between these approaches and discuss the
consequences of those relations to query evaluation in databases obtained
by circumscription.

I'm pleased to announce the election results for 1985.  We had a total 
of 1,766 votes (out of 8,923) or 19% of the membership voting.

Raj Reddy was confirmed as President-elect by 89% (1571) of the vote.
With 8% (145) voting for write-ins.  Nils Nilsson and Doug Lenat received
the highest number of write-in votes (4 each).

For the position of Councilor (1985-1988), the four councilors will be
John Seely Brown (70%/1245 votes), Tom Mitchell(63%/1113 votes), Fernando
Pereira (47%/826 votes), and Ryszard Michalski (41%/717 votes).  I should
mention that the four place for councilor was almost a three way tie
with Aravind Joshi (40%/709 votes) and Chuck Williams (40%/702 votes).

We will be introducing the new officers during the Executive Council
Meeting on Thursday, August 22, 1:00pm in the Chancellor's Room,
Pauley Pavilion.

\centerline{\bf Survival and Prosperity:}
\centerline{\bf How Should Computers Help Us?}
\vglue 1in
{\it
What follows is a slightly edited transcript of a panel 
discussion that took place at San Jose State University
in October, 1984.  The participants are three of the 
most respected researchers in computer science, who happen
to disagree on many political issues.}

{\it Moderator:}  ``Survival and prosperity:  how should 
computers help us?''  I chose that title for the panel discussion
because survival and prosperity are absolutely unarguable goals.
Everyone on the planet wants to survive and prosper.  I promised
my students that I would say a few words at the beginning about
why I organized this discussion.  I thought that perhaps the 
best way to do that is to mention a couple of the issues I'm 
worried about.  I was in Karlsruhe, West Germany, a year ago
at the 1983 International Joint Conference on Artificial Intelligence.
There was considerable discussion at that conference about the 
missiles which the US is installing in West Germany.  I became
aware that the guidance systems of those missiles incorporate
new computer technology that gives them unprecedented accuracy.
A television image of what is below them while they are descending
on a target is compared with a stored photographic image of that
target.  These stored photographs are obtained from reconnaissance
satellites.  A course correction is then calculated on board
the descending warhead.  Roughly speaking, these missiles can
go right down a smokestack.   That changes the strategic game
because you can no longer afford, say the strategic thinkers,
to wait out the other side's attack and {\it then} decide how and 
when to retaliate.  It becomes a case of ``use 'em or lose 'em''.
The intended recipients of the attack of those Pershing missiles
have only seven minutes to detect the incoming missiles, get a 
message to headquarters, decide whether to fire back, return the
instructions, ready their missiles for firing, and let them go.
Here is one case where computer technology is changing the 
name of the game in defense.  

Another illustration of the kind of development that led me to 
convene this discussion, is that {\it Business Week} estimates that
of the 23\% of American jobs that are now in manufacturing only 
10\% will remain in the year 2000.  That's only 16 years from now.
13% of American jobs, which is more than half the jobs in manufacturing,
are going to be lost to automation.  I don't hear a lot of discussion
in the public media about what's going to happen to those workers, and 
what's going to happen to the economy as a whole, as a result of the 
progress of automation.  

Technology is having a slow but steady influence on our lives, and 
in ways that are not necessarily under our immediate control.  Rather
than go on enumerating examples, I'll let the panelists discuss the
issues in the way they see fit.  

I want to introduce the panel members.  On my far right we have
Professor John McCarthy.  John was one of the founders of the MIT
Artificial Intelligence Lab, together with Marvin Minsky, in the late
1950's.  He later went to the West Coast and founded the Stanford
Artificial Intelligence Lab.  And, somewhere in between, he invented
the programming language LISP, which has been the heart and soul of
artificial intelligence programming.

{\it John:}  Indiana.

{\it Moderator:}  That's where it was?  Next to him is Terry Winograd,
Professor of Linguistics and Computer Science at Stanford University.
Terry finished his Ph. D. at MIT in 1970 and has become famous for 
writing computer programs that enable the computer to converse in 
ordinary language.  

Next to him is Severo Ornstein.  Severo was involved
in the development of the first microcomputer in the early 60's and 
also played a key role in the development of the ARPAnet, which is the 
computer network that connects the major universities and research centers 
in computer science in this contry.  Severo was a senior scientist at
Xerox Palo Alto Research Center.  He has taken an early retirement from
that position to serve as the national director of Computer Professionals
for Social Responsibility.  

The format of today's discussion will be that each of the three 
speakers will give an individual presentation.  After that, there 
will be a period of discussion between the three panelists, and 
after that there will be questions from the floor.  The first 
speaker will be Severo Ornstein.

{\it Severo}:  I want to begin by reading four quotes that have come
to my attention in the last couple of months, which I think raise
some issues we will want to discuss.  The first quote comes from a 
document called {\it Strategic Computing}.  This is a new program
that was initiated by the Department of Defense, which has funded
over the years a fair amount of computer science in this country 
through an outfit called Defense Advance Research Projects Agency.
Last fall, it issued a rather new kind of document that prescribes
more specific applications-oriented work than I think it had previously
sponsored, and I'll only give you one quote from that now, a document
that gives me considerable concern.  It says here,
\beginquote
Commanders, in particular, remain considerably concerned about the
role autonomous systems would play during the transition from peace 
to hostility.  An extremely stressing example of such a case is the 
projected defense against strategic nuclear missiles.  Systems must
react so rapidly that it is likely that almost complete reliance 
will have to be placed on automated systems.  At the same time, 
the complexity an unpredictability of factors affecting the decisions 
will be very great.*
\endquote
Now, that's pretty serious talk, it seems to me.  I'm not really sure
what they're referring to here.  I think this anticipates Star Wars,
because it talks about defense rather than retaliation.  The thing
that's new about Star Wars, most of you may not know, is that we're
now talking about a boost-phase defense.  Today's missiles break up,
after the boost phase, into ten or more small pieces.  Each of these
separate pieces has a warhead and can be independently directed to a
target.  Some of the pieces are decoys and some are real warheads.
In the boost phase, they are still carried by one large missile,
and that missile gives off a lot of heat, so it is easily detected
by infrared detectors.  It takes about three minutes for a missile
to get to the point where it starts dispersing its individual warheads.
If you believe you're going to try to do anything about it in that phase,
you have about two minutes, maybe as much as five minutes sometimes.
It is certainly true that if anybody wants to do anything like that,
decisions will have to be made in minutes.  Now, when we talk about
retaliation and mutual assured deterrence, the decisions are also
relatively short term, especially when you talk about the defense
of Europe.  That's one quote.

The next quote I want to read comes out of this ({\it holding a
brochure aloft}).  This is a brochure advertising a series of seminars
that are being given in cities around the country, in San Diego,
Los Angeles, San Jose, and on the East Coast, in Washington, New York,
and Boston.  This is a two-day seminar.  You pay $500 to go for two days,
and you find out things like the following: ``leading edge applications
for autonomous vehicle control, target acquisition and engagement,
communications and intelligence, high-pay applications for AI robotics,
weapons systems, impact on air-land battle 2000''---that's the way wars
are supposed to be fought in the year 2000---``battlefield artificial
intelligence and robotics:  who are the key players, should man be removed
from the loop, what's feasible now, where are we headed, what weapons
systems upgrade options robotics makes possible, when will performance
equal profit?''   Number two.

Number three is really quite different.  It comes from the front page of
the manual for a small personal computer you can buy.  It reads as 
follows:
\beginquote
The company makes no warranties, either expressed or implied, with respect
to this manual or with respect to the software described in this manual,
its quality, performance, merchantability, or fitness for any 
particular purpose.  The software is sold or licensed as is:  the
entire risk as to quality and performance lies with the buyer,
not the company.  The buyer assumes the entire cost of all necessary
servicing, repair, or correction, and any incidental or
consequential damages.  In no event will the company be liable for
direct or indirect incidental or consequential damages resulting from
any defect in the software, even if the company has been advised of
the possibility of such damages.
\endquote
I think that contrasts with the first two quotes.

The last quote is, to me, the saddest of all.  It comes from a 
{\it Washington Post} ABC news poll.  It reads as follows:
\beginquote
One issue appears to be determining voter choices in the 1984 presidential
election---financial self-interest.  Voters say they think they 
personally will be better off under President Reagan, and probably
are supporting him now regardless of how they feel on most other
issues.  Many voters say that Mondale would be better than Reagan at
reducing the threat of nuclear war, but that they personally would be
better off financially under Reagan.  How would these people vote as
of now?  By 568\% to 31\% they back Reagan.  Many voters say they 
think that Mondale, more than Reagan, would see to it that 
government programs are fair to everyone, but that they personally
would be better off financially with Reagan as president.  How would
they vote?  By 71\% to 20\% in support of Reagan.  About one-quarter
of registered voters think that the nation's economy is getting worse
instead of better.  Most of them support Mondale.  The ones in
that category, who think that they personally will be better off
financially under Reagan, back the president 70\% to 27\%.
\endquote
It is their personal financial status, not the nation's economy,
that counts most.  Pretty grim stuff.

It's very hard for me to talk about prosperity when it seems to me
that our survival is really very much in jeopardy.  I've put myself
on the line with Computer Professionals for Social Responsibility
in order to devote myself completely to this issue, becuase it seems
that we are in considerable danger.  The moderator has already raised
the issue of what part computers are playing in this.  It is certainly
true that the increased precision of missiles,  which is due almost
completely to computer technology, is changing the character of the 
nuclear arms race.  It is putting things more and more on a hair
trigger.  Today the question of building larger bombs is no longer
of such relevance or interest.  People have figured out that you 
could do a lot more damage by distributing a larger number of 
smaller bombs, and furthermore, you can place them precisely, so 
that you can begin to think about hitting the other side's missiles
themselves.  That's exactly what we see happening.  The talk we 
hear out of the Defense Department is increasingly of a first strike,
of being prepared to fight and take out the other side's missiles.
I'm very concerned because I believe that the quote I read from
the computer manufacturer represents the situation the world is
facing.  The fantasies that people have about what we might be able to 
build as Star Wars systems are really just that---just fantasies.  
They don't take into account the serious problems that we have 
with all the computer systems we use today.  Systems of any magnitude,
as we all probably know, suffer problems of one sort or another.  
They slow down or they stop working consistently.  I went to my bank
today, and the automated teller machine wasn't working.  Anybody who
goes to his bank has that happen to him sooner or later.  It seems
to me to relate to what goes on in planning for a defense system.

I think we Americans have come to belive that technology can do 
amost anything.  Scientists are more usually wrong when they say
you can't do something than when they say you {\it can} do something.
It is very difficult to be negative about things.  On the other hand,
there were a lot of people who tried to promote the law of perpetual
motion in the last century.  Finally, it turned out that we had to accept
the second law of thermodynamics, which says you can't build 
perpetual motion machines.  Nobody really likes the second law very
well because it says you can't do something that you ought to be able
to sneak up on.  We tend to feel that technology can solve all our 
problems because it has solved so many in the past. I don't believe 
that any longer.  I think we are grasping at straws now.  We are
getting closer and closer to crossroads where we're really going to have
to decide whether we are going to act like selfish, greedy, arrogant,
antagonistic people, or whether we are going to dominate that side
of our character with concern about society as a whole.   I think that
that time is really here.  Computer people are part of society, and 
our technology is very heavily embedded in the arms race.  I represent
that portion of the professional community that thinks we should really
start raising questions like this and ask what we as individuals can 
do.

{\it John McCarthy}:  That was quite an emotional address, and 
I'm not very capable of responding, nor do I wish to respond, in kind.
I want to talk about survival, and I also want to talk about 
prosperity.  I'll talk about survival first.  The problem of 
nuclear war has been with us for thirty-nine years.  We have 
survived so far with a wide variety of governmental adminstrations  
who advocate a wide variety of policies.  (Although what they advocate
when they're out of office tends to be more drastic in one direction
or another than what they do when they are in office).  However,
when somebody says we should make a drastic change, then he is really
taking a risk.  Whether this drastic change is in the direction
of war---armament, or a more militant policy---or whether this change
is in the direction of unilateral disarmament, he's saying, well, 
somehow the situation has become desparate.  Now in Severo's talk
there were various notes of ``the situation has become desparate,
and we should start questioning'', and so on.  Well, this whole
thing, including most of the arguments on both sides, has been 
around for at least 30 of the 39 years, and perhaps all of them even
started in 1945 between the atomic bombing of Japan and the end of
that year.  

There are of course, some questions about:  something
may have changed recently.  One thing that may have changed,
at least some people have argued that it has, is the balance of
nuclear and conventional power.  If, indeed, it's true that an
imbalance has appeared, then it is probably an improvement to 
rectify it.  One of the things I want to mention there has 
something to do with the moderator's remarks about the US 
installing missiles in Germany.  One has to recall that the 
then-Chancellor of West Germany requested President Carter to 
do something about the SS20 missiles.  One has to remember what
kind of event started it.

I'm going to speak a little bit about the Strategic Computing
inititative.  This has, in the minds of its congressional supporters
and in the minds of the DOD people who put together the package,
two purposes.  The first one is straightforward defense research
support.  Many defense plans depend heavily on computing, and we can
save a lot of money in social turmoil if we could maintain our
technological lead over the Soviet Union in as many areas as possible.
We have no draft at present.  They have three years of essentially
unpaid compulsory military service, and spend a substantial fraction
of the GNP on the military.  If we are not in a position to maintain
our lead then we may have to restore the draft.  

The second purpose of the Strategic Computing initiative seems to
be to offer some response to the highly-publicized Japanese Fifth
Generation Computing project.  With regard to 
competition with Japan, I have some problems with the Strategic
Computing Initiative myself.  These stem from its focus on hardware
and its focus on short-term applications.  My opinion is that
progress in artificial intelligence, including the AI which is 
applicable to defense problems, will be faster if there is more
emphasis on basic research.  This opinion is based on the belief
that current systems technology is inadequate to achieve many of the goals
that people are hoping it will.  Moreover, the problems that I 
see are fundamental and not merely going to be solved by throwing 
more money and power on them.  However, I can't put the 
fault for this mainly on Congress and the DOD.  The mistake
in over-emphasis on short-term goals affects the computer
science community also.  

With regard to defense, we have to think about what kind of world
we are living in.  My opinion is that Reagan was correct when
he referred to the Soviet Union as the Evil Empire.  
Fortunately, he seems capable, unlike some people, of keeping
two ideas in his head at once.  We should not forget that the 
Soviet Union is an Evil Empire.  He also emphasizes that we
we have to negotiate with it and reduce the probability of war.
Maybe we can even negotiate an agreement that will reduce our and
their expenditures on armaments.  Maybe we can even keep military
service voluntary.

Now I want to go to the other topic, which is prosperity.
There is a lot of talk about the social responsibility of 
computer scientists.  As we see what form this is 
taking, it is only peripherally related to computer science.
In my opinion, there are some areas where computer scientists and 
computer professionals have a responsibility which is more directly
related to their competence.  I want to mention some of these.
First of all, everybody grumbles, and has grumbled for years, about 
bad service from computer systems.  You complain about a wrong bill,
somebody promises to fix it, and they don't, and you get a bill with the
same error the next month.  Now, does that have something to do 
specifically with computer technology?  It does.  It has to do with 
the computer technology prevalent twenty years ago, and still often
used today, in which the records of a business are kept on tape, and
so when this person takes your telephone call and proposes to change
your record, a card has to be punched, something has to be entered,
and if there is any mistake in that correction card, or whatever it 
was, then the thing gets kicked out, and lo and behold you get the
same bill next month.  Now this is something, in my view, that
your scientists have some responsibility for.  

The second thing computer scientists have some responsibility for
is what I call ``fascist computer programs''.  These are programs
promoting the idea that the user is an idiot and must be 
carefully controlled and prevented from possibly doing anything
wrong.  I believe that when these programs are put in a computer
science environment like mine they are moderately harmful, but 
people can, after all, refuse to use them.
When they are sold to personal computer users, they can try to 
get a different program.  When they have to be used by 
people who have no control over their direct job then they can be
really harmful and can make the job a lot more unpleasant.
It is the responsibility of the computer scientists and computer
professionals to say that this characteristic of programs is 
unnecessary.  In fact, one wants to go in another direction.  One
wants to make programs that will enhance jobs
by making it possible for people to have more of the 
information required for their job.  They should have access to 
the files and be able to change them when it's necessary, and there
should be an adequate audit trail to show who changed it, so that you can
let just anybody change it.  

The next thing I want to mention is the possible use of computer
technology to ensure, one might say, an additional right we don't have
already.  For example, no institution should be allowed to ask the people,
to require from a person an answer to a question when it already has
the answer in its records.  They should be required to ask at most
that you confirm it, and ask only once that you confirm it.  

My next topic is prosperity and productivity.  We have had substantial
degrees of technological innovation since around 1600.  There have
been increases in productivity since then.  Worries about the increases
in productivity causing general unemployment have been raised since almost
that time.  However, economists have never been able to find any 
correlation, within a country, between the periods of fast
technological advance, and the degree of unemployment.  Nor have
they been able to find correlations between technology and unemployment
by comparing different countries.  It is simply not true that the 
countries with less technology have less unemployment.  In fact, they
tend, on the whole, to have more.  We can ask ourselves the question:
Is the automation and computerization that is taking place today
something qualitatively different, or is it more of the same?  I 
believe that it is, up to now, more of the same.  That it is of a piece
with the previous increases of productivity which have, in fact, led
to an increase in prosperity.  

The final thing I want to mention in this
list of things which are the responsibility of the computer community
is that computer technology has not been used anywhere nearly to the 
extend that it can be to make freedom of information effective.
There is the Freedom of Information Act which requires the government
to put certain things in reading rooms in Washington, where certain
relatively well-to-do organizations, whether they be companies or 
whether they be environmental organizations, can look at it.  But in
terms of requiring them to put it in a computerized data base where anybody
in the country can call up from his home terminal and get the information,
this hasn't happened.  It is the responsibility of the computer 
community, who else, to point out that this is feasible, and that we 
can make this right more effective.  This is in my opinion the 
list of opportunities that the computer community actually has to 
exercise its social responsibilities.  I think we ought to have an
organization for this.  We could cal it something like Computer
Professionals for Social Responsibility.  

{\it Terry Winograd}:  I want to talk for a few minutes about the 
Strategic Computing proposal which was one motivating factor for this
discussion.  Certainly it has motivated a lot of discussion within
CPSR and the press.  I'll just give a little history of it, which was
alluded to earlier, but I'll fill it in.  About two or three years ago
a group of researchers in Japan put out a document describing what they 
called the Fifth Generation Computer.  That document talks about new
advances in computer technology, in particular artificial intelligence,
and expert systems are going to make a major change, a major increase
in human prosperity, and it goes on in quite flowery style about all the 
wonderful things computers can do in the world.  Along with that, they
put a lot of money into a particular program of research. 
They invited the world to conferences and said, ``Come aong with us.
It's the new Fifth Generation of Computers that will really be much
better for people than the old ones.''  People in other countries,
in some ways, said ``Yes, that's wonderful'', and others, at the same
time, said ``You'd better be careful because if it's really as good
as they say it is, the Japanese are going to come in first again,
just like they did in cars, microcomputer chips, cameras, and electronics.
In the end they will win and we will lose, in the economic sense at 
least.''  Various people in various countries, including the U.S.,
England, and France, wrote pieces, books, articles, and held
conferences, saying we'd better get in and do something fast or we're
going to be in trouble.  Governments of these countries each 
responded in their own ways; they set up committees, did studies, and
came up with the money.  The U.S. was interesting in that, rather than
doing it through some kind of a broad science funding organization such as
a Board or Ministry for Technology, it was picked up by the Defense
Department.  In particular, by the Advanced Research Projects Agency
(ARPA).  The Strategic Computing Initiative is very careful never to 
mention the Japanese, but what's between the lines is that the 
Japanese are right about this being a great technology, and we can
use it to build smart weapons systmes that will put us in a much
stronger position.  Therefore, we should support it as a military
project to apply Fifth Generation techniques to the development of 
automated intelligent weaponry.  It's quite explicit in the sense
that it lists projects: pilot-assist systems for the Air Force, 
a battle management planner for the Navy,
and an automated driverless walking tank for the Army.  There
were various responses to this in the academic community.  A number of
people found it quite uncomfortable, in that ARPA has been sponsoring
artificial intelligence research for many years, since the beginning
of the field.  But it's always been done in the spirit, ``Let's
sponsor good basic research, and when it works out well it will be to 
the advantage of the military as well as everybody else.  You people in
universities could go on doing what you consider basic research, and what
your students, and your administration, feel comfortable with.  When
the results come out, we will then put them into industrial labs and
let them go ahead and turn it into weapons.  

The Strategic Computing initiative marks a direct attempt to create an 
explicit partnership between the universities and the more basic
research labs and the actual contractors who are out there making
weapons, the people who would go to the conferences and seminars
like the one whose advertisement Severo read aloud.  
This raises, once again, the question that has lain dormant since
the Viet Nam war:  What is appropriate for those of us who consider
ourselves more basic scientists, researchers, those who are in academia,
what is our responsibility with respect to who pays for the research,
what it's getting used for, and how it's being directed?

I think it would be misleading to see this particular proposal as a 
major shift in that whole question.  The total budget for Strategic
Computing is relatively small, compared to the overall defense budget,
or even to the overall university science budget.  Much of the money will 
end up not in universities, but in companies who pay for those 
expensive AI seminars.  The net result is not going to be that all 
of a sudden university computer science departments are turning to war
machines.  But it raised again, in a fairly sharp way, the basic question
of what responsibility do we have as scientists for the work that we do 
and the directions in which it is being used---even though we ourselves
are not actually out there building military applications?    
What impact does military funding have on the people who do the 
research---even in projects proposed by a faculty member, not a
project pushed by the DOD like this one?  What impact does military
funding have on the way the research gets done, on the conduct of 
the university?  There is a whole range of issues which go beyond
any specific proposal.

In order to answer the question, ``Why shouldn't I be 
perfectly happy to take money from ARPA to do strategic computing if I
believe that what they are funding is in fact good science that has
non-military applications?'', it is important to take a step back to 
a very basic issue that I think John was addressing, and on which I 
have a different view.  The issue is, where we stand and where we
are heading.  Are we in a present danger?  Are things more or less
stable and going this way for forty years, and why shouldn't they 
stay that way?  Or, are there things happening which call for
immediate action?  I think the technological and social trends are
in fact accelerating.  It is not simply a stable situation.  
I'm talking about short response times, less ability to consider 
things, less ability to take into account what is really happening,
pressure to act quickly or lose your chance. 
I think all of those things are accelerating rapidly and have a 
very serious impact on the possibility that somebody will, in a moment
of crisis, push the button.  Saying that we've gone 39 years and 
nothing's happened yet is like saying to a terminal cancer patient,
``Look, you've lived this long and you haven't died yet.''
The fact that it hasn't happened yet is hardly comforting if you look 
into history, and find that wars have happened many  times after a 
long build-up during which nothing has happened---yet, there is some
spark, and there it goes.  In the past it has always been just a few
local vicinities that got wiped out.  There's a qualitative difference
now.  I think politically we're in a cycle and this is certainly 
nothing new in history.  Some people, including Reagan, believe that
the way to solve your problems is to win, to be stronger, to be patriotic,
to be tougher than the other guy, to get out there and battle it out,
and come out on top.  Again, this is not something new in history.
It takes on a different flavor now, however, when the winner is the
one who dies with the most toys.  The whole concept which worked perfectly
well for millions of years of evolution, when you had one person
or a small number of people, fighting each other, and the fittest would
survive, is just outmoded today.

I'm not about to change human nature; nevertheless, we either go along
and accept that kind of psychology, or we do some things which in 
some ways catch some people short, make them more aware.  For
instance, take the talk about keeping our technological lead over
the Evil Empire.  What it means is, keep a technological lead so that
when the fight comes, we will be the winners, we will kill them first.
We see an increasing sense of dependence on the military.  The success
of the military is equated with the success of the country, prosperity,
and happiness.  

One of the things that makes a difference is not going along with it.
Having said, ``I won't do that'', we still have to ask the question,
what is our responsibility other than to say we don't want to be 
involved in military work?  There is a substantial number of people
for whom this is an important question.  I can see that from the way
CPSR has grown.  It is having the kind of impact we need in places where
people who are members are having discussions with people in their
work places.  These are feelings which  are often unexpressed, although
they are widespread.  

John raised an important issue:  what would it mean to have computer
science which pushed in the direction of creating conditions where
someone who worked in a bank or a factory would have legitimate
realistic input into what kinds of conditions of work were created
by the system?  We could ask, for instance, what would it take to 
design systems which are more responsive to people, instead of the 
question, what would it take to design circuit chips which operate at
very high speed under high radiation conditions.

{\it John McCarthy}:  Terry mentioned Viet Nam.  People did a lot about
Viet Nam, and eventually they succeeded in changing U.S. polociy, and 
we got out.  The result was a tremendous tragedy.  More people died
in Viet Nam, in the five years after we got oout, than died in the 
previous thirty years.  The people in South Viet Nam, almost all of 
them, didn't get out with us.  They thought they could live there.
It took two or three years before people began to get desparate and 
started trying to get away in small boats.  I think the point I'm 
getting at here is that one can have errors of both kinds, and in my
view we committed such an error and may commit another.  

I want to mention a project for which I am currently applying for
a grant.  One of the slogans we hear today is that we want faster
computers, and everybody seems to agree that the way to do that is 
to make them run in parallel.  There are proposals to make multiprocessor
computers, with as many as 500 or 1000 processors, and some people
even talk about 10,000 processors, and one of the major applications
that is proposed is artificial intelligence.  All sorts of people are
proposing to make thousands-of-processor systems to do things 
that haven't even been done with two.  So this makes me a little
nervous.  What I have proposed to them is that they buy currently
available multiprocessor systems.  There are two vendors competing
to sell it to us.  We put on it a LISP for multiprocessing that has
recently been developed, or rather the ideas for it have been 
developed, by Dick Gabriel and myself.  In order to check out the 
parallelism, that this language is good for writing parallel programs,
we want to put on it MACSYMA, which is a system for doing algebraic
computations.  It has a wide variety of algorithms in it, and so we'll
get a wide variety of problems in making these algorithms parallel.
It looks like the defense department, that is ARPA, is taking a 
favorable view of this project and they may give us a million and a 
half dollars to buy this computer and an additional sum of money to support 
people who do all these things.  Now, they believe, and I hope correctly,
that doing this will help them eventually, in good time, with the 
application of artificial intelligence techniques and parallel computations
to military problems.  

Now, I should remark that the interest of the defense department in 
pushing things in the direction of applications is not new, nor is it
even at its most intense phase.  Its most intense phase was in the 
early seventies.  That came about through an interesting alliance of
liberals and conservatives.  The liberals thought that the defense department
shouldn't be supporting  university work because it would corrupt them.
The conservatives thought they should get more bang for the buck, and 
so the Mansfield Amendment to the Defense Appropriation Act was passed,
which said that the military had to certify that  each piece of research
they were supporting had a direct military application.  Then they went
around asking people, ``How will this stuff have a direct military
application?'', and of course, some large fraction of what they were
already funding could be said to have direct military application, even
if that hadn't been said when the work was originally set up.  So the
disaster wasn't as bad as it might have been, but still it was fairly bad.

Now another remark on defense funding:  in 1960 we spent 10\% of our 
GNP on defense, and in the late seventies it was down to 5\%, and 
Reagan wants to raise it to 7\%.  So it isn't as though defense  
costs are about to overwhelm us.  

Terry talked about having a computer science that helped people,
but I found his remarks rather vague.  What I would like to see is
some specific projects that would help, and I want to mention one
that I have been pushing for many years.  This is an electronic
***Vietnam
library.  I wrote my first paper about it in the late seventies.
It was at that time, and has been since, technically feasible to 
have one giant computer library containing everything that has been 
published in the world.  Anybody could get access to what would
amount to the Library of Congress from his home terminal, at any
hour of the day or night.  Back in 1971 or '72, I went to see Ed
Davidson, Nison's Science Advisor (now vice-president of Exxon).  
At that time, the U.S. had two and a half billion dollars worth
of Indian rupees, which couldn't be converted into dollars and
taken out of India, left over from famine aid in '66.  I proposed
that we use some of these rupees to hire people to type in parts of 
the world literature.  Mr. Davidson just said, ``Well, I haven't got
any power,'' which turned out to be true, since a few weeks later
the President fired him.  So that was one attempt.

A more recent attempt has showed some signs of success.  The French
government has set of a world center for informatics and human resources
which is supposed to do good for the Third World.  They like this project, 
and they're going to do a prototype in Marseilles, put some French 
literature, as much as they can afford, on it and start out as a 
small public computer library.  What I claim is that people that do 
things like that actually do some good, more good than those who talk 
about ``re-orienting computer science''.  I believe that the 
Scandinavians, who have a deep enthusiasm for re-orienting computer 
science, have not really made striking accomplishments.  At least 
I don't know about any computer services available in Scandinavia that 
we want to copy.  The desire to copy things seems to run the other way.

{\it Severo Ornstein}:  As far as Viet Nam is concerned, it's
not clear to me who stopped the Viet Nam war.  I suspect a large part
was played by the large number of children of the people in Congress
who were starting to get killed.  It's not clear to me that people were
concerned about the slaughter, or should be blamed for the war either.
I think most of the bad decisions were made in the late fifties and
early sixties.  We chose to suport one dictator after another in
South Viet Nam and built up a regime there that was hated by a large
part of the Vietnamese population.  We had opportunity after opportunity 
to mend our ways there, and we chose not to.  The blame for the 
giant slaughter and the terrible things that happened since we 
left is not to be laid entirely on the peace movement of the sixties.

Working my way backward through the list, I find that I don't
completely disagree with you, John.  I find that I absolutely agree with 
you that we need more basic research in computer science, and I 
would probably agree with you that the DOD has, through DARPA, over
the years funded research in a way that practically no other 
institution in the government would have been able to do.  I have 
enormous admiration for the people who headed DARPA over the years.
I worked with most of them, and I think that the state of 
computer science in this country today is in no small part due to the 
quality of the funding that's come from DARPA.  Furthermore, I believe
that there are a lot of people in the Defense Department 
who are as concerned about the issue of nuclear war as I am, 
perhaps even more so, because they know more about it.
So I don't take just one piece of the government to task.

I think we all bear a responsibility, and that's what Computer
Professionals for Social Responsibility is all about.  I think we
all have a piece to play.  

I was talking the other day to a chap who was, until relatively
recently, in charge of what is know as the Star Wars program in the 
Air Force.  It's a long-standing program---although the term has been
used to describe President Reagan's plans, there has been a program
of space technology in the Air Force for a substantial period of time,
and there's a fellow by the name of Bowman who has been in charge of
it for a number of years.  He's got a Ph. D. from Cal Tech, and he
is now in charge of an institute in Washington, and spends his
time traveling around the country, and in fact, around the world,
speaking out against the Star Wars program, arguing that it is a waste of
money, and extremely dangerous for arms control talks.  So there is
someone who was absolutely at the center of the program, who is now
arguing hard against it.  He made a comment which I think is 
appropriate about the `Soviet threat'.
He said, ``You know, there's really not enough Soviet threat to go 
around among all the programs we're trying to fund in Congress.  We
have to divvy it up very carefully these days.''

{\it McCarthy}:  Is that an argument or just a wisecrack?

{\it Ornstein}:  I think it's a wisecrack which has something behind it.

{\it McCarthy}:  {\it What} does it have behind it?

{\it Ornstein}:  Well, let me say a little more.  Many of you may not
know that in 1945, Harry Truman set a photographer over to Japan to 
record the damage at Hiroshima and Nagasaki after the bombs were dropped,
and the human suffering.  That fellow brought back films which were 
immediately taken by Truman, classified, and tucked away in archives.
That fellow was very disturbed by what he had seen.  He spent from 
1945 to 1979 attempting to obtain from one administration after another the
right to show those films publically, and was in every case refused.
Finally, the films were declassified quietly in 1979, and it took them a
couple of years to find that out, but in the meantime the damage had
been done.  You might ask yourselves the question, ``Why was it felt
necessary to keep those films heavily classified?''  It wasn't an accident,
this chap wrote to President after President.  He spent a large part of his
life trying to get that material released, because he felt it was so 
important for the public to see it.  Yet the government, in one 
administration after another, refused to release it.  The only possible
anser I can come up with is that the government had another agenda it
intended for the public.  

I guess I believe that Dr. Bowman's comment about the Soviet threat
should be well received.  The Soviet threat is usually exaggerated.
People who use this argument the most, usually know the least about
what actually happens inside the Soviet Union.  The Soviet Union is
certainly corrupt.  It treats its people terribly, and has a terrible
policy in Europe.  There is just no question of that.  People in 
glass houses should be just a tiny bit careful, however.  It seems
to me that while we have considerable freedom in this country, our
behaviour throughout the world has not in general been admirable.
We have looked rather hard after our own self-interest.  I think you
have to be careful when you hold up the Soviets as THE Evil Empire,
to worry about the old adage about people in glass houses, because
I think that we have our own problems to worry about.  

I agree with you about a wider scope of concern for Computer 
Professionals for Social Responsibility.  I am personally 
principally concerned about nuclear war, because it seems the 
most important thing to worry about.  Nonetheless, I have
participated in meetings having to do with issues of civil
liberties, technology, and privacy legislation that were chaired 
by the American Civil Liberties Union (ACLU) in Washington.  
We went to some meetings there last winter, and more recently to 
an American Bar Association meeting in Chicago, where we were 
discussing the problems of individual liberty and privacy and the 
Privacy Act of 1974, which desparately needs updating.  They debated
for two days on the definition of privacy, which I thought was a
little much, but they share our concern with the issue.  I agree
with you that CPSR should be concerned with other issues than 
nuclear war.  I point out that we {\it are}.  If you feel strongly
about that, I happen to have here an application blank for
membership in CPSR.

{\it McCarthy}: You seem to believe that the best way to make
social progress is to forbid suffering.  To find something that is
bad, and forbid it.  Now that's better than the primitive view---
that the best way to make social progress is to kill somebody.  But
still, it's less good  than that the best way to make social progress
is to build something.  What we have here is simply the question,
``What computer science should be forbidden?''  If that's your 
notion of social responsibility, then I don't want in.

{\it Winograd}:  I don't believe that anything in computer science
should be forbidden.  We are talking about {\it applications}.

{\it McCarthy}:  Your point is that what social responsibility consists
of is finding out what applications should be forbidden---and forbidding
them.  Rather than what is positive and {\it should} be done.

{\it Ornstein}:  I don't know how to use computers to make people 
better, which seems to be the fundamental problem.  I do know how
to use the computer to kill people.  I think we ought to forbid that.

{\it Winograd}:  You all came here under the impression that this was
going to be a discussion about computers, and most of what you 
heard is about wars, Viet Nam, and weapon systems---issues which,
although computers relate to them, are not about computers.  That's
telling.  

Computers aren't the problem and computers aren't the solution.

They may raise points, they exacerbate, they make things more urgent,
or they play a role in the balance, but ultimately the meaningful
questions about computers are questins about society in which computers
play a role.

You might ask why Severo and I are part of an organization.  Why have
an organization specifically organized around computers?  Why not go to 
the Democratic Party, or the Socialists, or the John Birch Society,
which are explicitly political groups.  I think the answer is, that
we are members of a profession. 
As a member of a profession, whether medicine or computer science,
any profession that has a public role in creating the understanding
of the world around us, you are responsible for putting forth 
an understanding which leads in the political and social direction
which you feel is right.  As a computer scientist, you can get up and 
talk about things like the reliability of early warning systems, to take
an immediate example.  You can say things which can have a real impact
on the public understanding and discussion about what kind of system
we want, that somebody who doesn't have the same background cannot.  

Politics isn't a matter for cocktail-party debate, or watching TV
at home.  In the end it comes down to what you do where you work
and where you are, and the people you work with.  The things we
do in our work are related to computers, and the kind of question that
needs to be raised in that context is, ``How is what I'm doing on
a day-by-day basis, in its own little way, leading in a direction
that I like or I don(t like, or that I think is right, or that I think
is wrong?''

I think John makes a very important point.  I may disagree with a lot
of the consequences he draws from it, but ultimately the question needs
to be ``What can I do that works?'', and not ``How can I stop this?'',
although, you need to ask that, too.  If the house is burning down,
you don't want to ask, ``Gee, how can I build fireproof houses?''
You want to put out the fire first.  Then, maybe the right question is,
``How can I build fireproof houses?''  As a matter of fact, that's
obviously a good question to ask.  

Part of what we at CPSR are doing is to begin asking both kinds
of questions.  We recognize that we(re not going to end wars and 
poverty by coming up with the right computer program.  On the 
other hand, we can choose directions.  We can choose things
that are more relevant to the satisfaction of people in their jobs,
for example.  So, in talking about re-orienting computer science,
I'm not disagreeing with John; but I don't think putting the Library
of Congress on easy access will make a significant difference in the 
quality of life.  

{\it McCarthy}:  Well, there is a direct social benefit of making
the world library available on a computer file.  That is, if you have
that kind of disk capacity, anybody can publish anything just by putting
it in a file and declaring it to be public.  This will give everyone
an effective right of reply.  If you listen to the radio and Reagan
says something you don't like, then you don't have any immediate chance
***what do the Democrats think ....
of saying, ``Well now, how do the Democrats think about that?''  In
a system of the kind I'm thinking about, you would go to your 
terminal and ask, ``What do the Democrats think about that?'' and
probably if you wait half an hour there would be something.
One of the enormous discoveries of politics in the last fifty years
is that you don't have to actually respond to the other guy's point,
you can just pick up something from your campaign speech and utter it.
In the old  days of the Lincoln-Douglas debates, one of them would
ask a complicated question, and the other guy would actually feel
obliged to answer it.  Now what I would like to do, being a reactionary,
is to restore that situation by making the right of reply effective.

This project was only one of several concrete proposals I made,
and I'd like to have some discussion of the others.

{\it Ornstein}:  Let me just say that we're talking aout a workshop
for exactly those issues, namely, what is it that society might be
doing with its dollars for computer research and applications, if it
weren't spending so heavily on military problems.  That is, if that
money were available to you, starting from scratch, what do we think
society should spend its money on?  There are problems in medicine that
one could address if one put money into that.  There are problems in 
education that could be addressed.  I think there is a variety of things,
and CPSR intends to address those questions.

{\it McCarthy}:  Now, if you would just avoid this silly business
of wanting to take the money away from the military, and simply say,
``How can we combine military and civilian money and get these projects
done?'', that would be better.  I mean, you spend all your time
trying to get the money away from them, rather than trying to 
spend it, trying to get some money for getting these things started.

{\it Ornstein}:  I think you have the wrong image.  The game is not
to get the money away from them.  The game is to stay alive.  That's
what realy motivates me.  I genuinely believe that, if I and a bunch
of you other people don't get out there and do the kind of thing
I'm doing, we're all going to be dead in thirty or forty years.

{\it McCarthy}:  That's what people said thirty years ago.

{\it Ornstein}:  As Terry said, just because we've survived till now
doesn't mean we'll survive forever.

{\it McCarthy}:  But you see, I don't even believe that the {it sign}
of what you're doing is correct.  What you're doing is making it 
{\it more} likely that we'll get bombed, rather than {\it less}.

{\it Ornstein}:  That's a legitimate question, and I'll be happy to 
debate that with you, but I don't think we have time.  Everything one
does has to be done with a certain caveat.  This game of nuclear chicken
with the Soviets is indeed a delicate game, and nobody proposed making 
drastic changes.  We proposed thinking about it very hard.  I see
a lot of people doing things without thinking about it very hard, and I see
a lot of people doing things in that arena for reasons I think are 
inadequate.  I'm proposing that we all ought to be thinking very hard 
about the issues and telling our government precisely what we think after
we think about it very hard.

{\it McCarthy}:  I'm going to challenge you on this ``nuclear chicken''
thing.  I don't think that describes the behaviour of either the U.S.
or the Soviet Union.  Each party is very much afraid of nuclear war.
We do not have the situation we had before World War I and before 
World War II where you had prominent political leaders glorifying 
war as something that brings out the manhood in the country.  You 
don't have a Mussolini pounding the table or a Hitler writing a 
{\it Mein Kampf}.  The nuclear weapons have indeed succeeded in 
scaring just about everybody out of that, except maybe a few movie
makers.

{\it Ornstein}:  I don't think I believe that.  I'm sorry.  
I think that people don't understand what we're faced with very well
at all.  I think that we are faced with a man who wraps himself 
in the flag and likes nothing better that having the F-15's go 
flying by.  A man who believes that is what keeps us alive and that 
more of those are necessary.  Everybody agreed in the early days
that with a hundred well-placed atomic bombs you could blow the hell
out of either country, and so you have to ask yourself, ``Why have
we been building more all the time?''  That's what I meant by 
``nuclear chicken''.  What has happened is that these weapons
have become symbols of power in their own right.  That the more you
have is what matters, whether it makes sense or not.  What is going
on is a substantial macho game of trying to scare the devil out of the
other guy.  The governments on each side are playing a very, very 
dangerous game.  It simply can be reduced to two teenage boys
out there on the lot shaking their fists at one another, and each
one is trying to scare the other more, swinging a little bit 
closer to the other guy's nose.  Sooner or later, by accident, it
seems to me, somebody will probably draw blood, and ultimately,
we will all be dead. It's a very simple scenario and I think that
it is really what's happening.

I myself am pretty much convinced that we are done for.  I think
we're watching the last of the species here.  I think, paleontologically
speaking, we're a relatively unsuccessful species.  The ants have
a much better understanding of what's required for a social system
than we have.  We're much too focussed on our own individual needs
and problems---not well-focussed on the needs of the society and 
not prepared at all to sacrifice our individual needs and desires for
the society.  I think that disappointing quote I read you earlier is
proof of it.  

I think we are done for.  I think that's really  what's going to 
happen.  But it seems to me that one has every obligation
to try and stop it as long as one is alive.  That's what I'm doing.

{\it McCarthy}:  The view that people are too individualistic and
are not sufficiently inclined to sacrifice their own interests for 
the interest of the community has an obverse side to it.  The obverse
side is that those who know what the good of the community is have
the right to coerce the remainder into sacrificing for the good of the
community.  This has turned out pretty badly.  I don't know whether I 
can accuse you of that, because you don't have any power.

{\it Ornstein}:  I'm pushing, you see, for democracy.  I think we've
lost a large part of our democracy in this country. Democracy goes
away when people don't take the responsibility on their shoulders
to uphold it.  Just going to the polls doesn't mean we have democracy.
I am simply encouraging people to become concerned about issues because
I think we take our survival and our prosperity too much for granted.

{\it McCarthy}:  But suppose somebody is listening to the arguments here,
and he's still not quite made up his mind as to who's right?  What's to
do then?

{\it Ornstein}:  The best that he or she can.  That's all we can ask
of any human being.  I don't think we're getting the best from most
people.  I'm trying to encourage them because I'm worried.
It's as simple as that.

{\it McCarthy}:  But, do you think that there is some correlation
between the amount which people have thought and the extent to which
they agree with you about what ought to be done?

By the way, it just occurred to me that you haven't said what ought
to be done!  Let me ask you a very concrete question.  Gromyko said,
``What we want from the Americans are deeds, not words''.  Now,
one thing we could do is make some kind of unilateral concession on
one of the issues, like we could say ``All right, Russians, in order
to improve the atmosphere, we'll agree that we won't test any 
Star Wars stuff'', and the Russians could say, ``Well, that shows
a little bit of realism.''  (All you ever get credit for from the 
Russians is realism.)  ``But we want a real deed.''  Well now, what
do have in mind we should do now?

{/it Ornstein}:  The thing that is fundamentally wrong is the mind set
and attitudes of the people.  We have an enormous amount of 
opportunity in the overkill we have available.  We've got enough
to blow them off the earth and they have enough to blow us off.
If you study the arms race, you see that what has happened over
the years, is that the Soviets have mostly mimicked our behaviour.
They have led relatively rarely, and in very few areas.   Practically
every significant event in the nuclear arms race has been initiated
by the U.S., and then five years late the Soviets do the same stupid
things, and then later we all regret that.  For example, MIRV-ing
our missiles, which everybody now agrees was a terribly bad idea.
Now it seems to me, given that kind of behavior, that there is 
the possibility of making a good wise move, as well as a bad move.
So it seems to me that one of the things one could do is to make
some fairly substantial cuts without giving away a thing of 
significance.  You give away only symbols, and in giving away 
symbols, you acknowledge the fact that we have to sit on this
earth together, and you don't do anything dangerous in the process.

{\it McCarthy}:  Do you remember the gesture of unilateral disarmament
that Nixon made?

{\it Ornstein}:  No.

{\it McCarthy}:  You can't.  So that's what comes of it.
Nixon completely gave up our ability to wage bacteriological warfare
as a unilateral gesture, and what we discovered is that the Russians
did not follow this.

{\it Ornstein}:  There are no guarantees associated with this.

{\it McCarthy}:  But it was tried, you see, and found wanting.

nils indicates that you would prefer that i talk about
gio's work in place of you. Thats ok with me, but i
will need to ahve a few minutes extra to fit that in.

To do that i will need about five more minutes than i

Bob,  I have talked with several people involved in the Glenn presentation
and have the following info (you wanted me to get back to you with my
reactions to your proposed agenda):

All the "presenters" on your agenda have been contacted and will be there
and ready to go as per the agenda--with two exceptions noted below:

1.  As you know, Jim Meindl will be away.  I presume someone is pinch-hitting
for him, but I haven't tracked that one.

2.  John McCarthy would rather you (or someone else) talk about Wiederhold's
work.

Are you planning to cover "robotics/vision."  I notice Tom Binford is
not on your proposed agenda.  (I think he will be out of the country during
that day, so maybe couldn't attend anyway.)

I will be away (even away from netmail) during Aug 12 thru Aug 25, so I
will just be getting back the day before the Glenn visit.  I presume you
have someone here to contact (Jim Plummer?) regarding any last minute
changes, etc.  I also presume that someone is arranging a meeting place
and will be sending reminders out to those who are on the agenda.  (No 
need to remind me; I'll show up at wherever the mtg is to be held bright
and early Tuesday morning, Aug. 27.  Could whomever is setting up
the meeting room pse let my secy know?  Richardson@score.)

If volunteer work is needed during this next week (Aug 5-9) for 
organization, finding rooms, etc that I can help with, please let me
know.

Here is your agenda with my comments in ALL CAPS:


Kahn - KB vlsi, Cooperating agents, Regular expression silicon compilation,
real-time analysis and modelling, distributed information theory
and vision (unless its covered in the robotics presentation).
WIEDERHOLD WORK.

- 5 minute summary only  (I DON'T SEE HOW YOU'LL DO ALL THE ABOVE IN 5 MINS.)

Meindl - 30 minutes - Foundry automation/CIS re Fast Turnaround & integrated
			System aspects, MIPS & design tools (Hennessy results)
(I PRESUME JIM MEINDL IS ARRANGING FOR SOMEONE TO GIVE THIS PRESENTATION SINCE
HE WILL BE AWAY.)

Feigenbaum - 25 Minutes - Knowledge Systems & Advanced Architecture

McCarthy  -  25 Minutes - Formal reasoning, Qlisp, logic programming
				benchmarking (gabriel results)
                          (AFTER DISCUSSIONS WITH JMC, I TOOK WIEDERHOLD
                          MATERIAL OUT OF THIS.)

Except for a few typos, I'll let what I said stand if the others let theirs
stand.  "Vietnam" is one word.  Use the American spelling "behavior"
consistently.  Nixon's Science Adviser was Dr. Edward David.  I first
wrote about the electronic library in the late 1960s.  You have "The
best way way to make progress is to forbid suffering".  I said "
forbid something".  There are more typos.

Dear Martin and Don,

I had been planning to write a letter to the SIGART Newsletter 
concerning the events that happened surrounding the IJCAI held 
in Tblisi, Georgia, USSR ten years ago.  While preparing the 
letter I heard that the Soviets have requested that COLING88 
be held there.  I have included comments on COLING88 in the 
letter to SIGART.  Enclosed is a copy of the letter.

I hope that you both will support my position and reject the 
Soviet Union's bid for the conference.  I sincerely doubt that 
they will reverse their position and release the scientists 
who would like to emigrate.

Should I send the letter, or a suitably modified one to the 
Journal of Computational Linguistics?  What might we do to 
put pressure on the Soviet Union in this regard?

I look forward to hearing from you.

Sincerely yours,

Jack Minker



            Tblisi 1975 - A Retrospective Review



                             by

                        Jack Minker

                   University of Maryland




In 1975 the International  Joint  Conference  on  Artificial

Intelligence  IJCAI  was  held  in Tblisi, Georgia, USSR.  A

major controversy, initiated by this writer, arose  concern-

ing  the holding of the conference in the Soviet Union.  Ten

years have passed and it is appropriate to review what  hap-

pened  then, and during the interim ten years to some of the

Soviet individuals who played roles in that incident, and to

other Soviet cyberneticians/artificial intelligence investi-

gators.


     My objections to holding the IJCAI  conference  in  the

Soviet   Union  were  stated  in  a  letter  to  the  SIGART

Newsletter, Number 47, August 1974, 4-5.  Two  major  objec-

tions were:


    (1) Soviet researchers who were relevant to the  confer-

    ence,  but  in disfavor with their government, would not

    be permitted to attend the conference.


    (2)  Individuals  from  countries  which  did  not  have

    diplomatic  relations with the USSR would be barred from

    attending the conference.  In particular I had research-

    ers from Israel in mind.



     I believed  then,  as  I  do  now,  that  international

conferences  must  be held according to agreed international

standards.  Any country that violates these standards should

not  have  the  privilege of hosting a conference.  That the

latter  two  concerns  were  real  is  evidenced  by  events

recounted  in  my  letter  following  the conference (SIGART

Newsletter, Number 55, December 1975, 1-2.).  Dr.  Aleksandr

Lerner,  who  had  been invited to participate as a panelist

was denied permission to travel from Moscow to Tblisi by the

KGB.  And Dr. Yoram Yakimovsky, an Israeli citizen who had a

paper accepted for the conference,  was  denied  a  visa  to

attend the conference.


     It was only through pressure by  the  IJCAI  organizing

committee,  and in particular by Dr. John McCarthy, Dr. Erik

Sandewall, and Dr. Patrick Henry Winston,  that  the  Soviet

government reversed itself on both issues.


     Why is it necessary to review  this  incident  now?  My

purposes  are  to  bring  the  status of some AI/cybernetics

researchers in the Soviet Union  to  the  attention  of  the

artificial  intelligence  community and to reiterate my con-

cern about AI-related conferences being considered  for  the

Soviet Union.

     Let me begin by  discussing  the  status  of  Aleksandr

Yankelovich  Lerner, Isai Goldstein, Grigory Goldstein, Ana-

toly Shcharansky, Eugene Grechanovsky, Viktor  Kipnis,  Gri-

gory  Minc,  Viktor  Brailovsky,  Nadezda  Fradkova and Haim

Kilov. Three of these scientists, Lerner and  the  Goldstein

brothers, attended the 1975 IJCAI conference. Dr. Alan Mack-

worth, acting on behalf of the 1985  IJCAI  invited  all  of

these scientists, with the exception of Brailovsky and Frad-

kova to attend this year's conference.  All  are  refuseniks

who  have,  over  many  years, requested exit visas from the

Soviet Union so that they may emigrate.


     Aleksandr Lerner, who  is  nearing  his  seventy-second

birthday  has been denied an exit visa from the Soviet Union

for over thirteen years.   The  Soviet  IJCAI-75  organizing

committee  "hinted"  the  information  that Lerner was to be

released "soon". The year was 1975.  Ten years later, Lerner

still  remains  in  the  Soviet Union. Several years ago his

wife died, and he was denied permission  to  have  her  body

buried in Israel.  Lerner, in spite of his age and problems,

continues to do research.  What harm can come to the  Soviet

Union by releasing him?


     The Goldstein brothers, who live in Tblisi,  were  able

to attend the 1975 IJCAI Conference through the intervention

of the organizing committee.  Many attendees visited them in

their  home.  Since 1975 they have been subjected to extreme

pressure by the Soviet government.   Grigory  Goldstein  was

sent  to  the  Gulag on a "Catch-22" charge.  Unable to find

work because he was dismissed from his job, and not  permit-

ted  to work in his field, he was convicted of "parasitism".

Over the past ten years the brothers have shuttled through a

series of menial jobs, all of which they lost when employers

learned of their refusenik status.  In  June  of  this  year

their  homes  were  searched, and they were interrogated and

threatened with arrest and criminal prosecution  -  a  cruel

irony.   For in sole reality, their "crime" is their wish to

emigrate.  Why aren't they permitted to do so?


     The case of Anatoly Shcharansky, who wrote a MS  thesis

on  chess-playing  by  computers,  arose following IJCAI-75.

Shcharansky, then in his twenties, also wished to  emigrate.

His  wife,  Avital,  was permitted to emigrate the day after

they were married, with the expectation that  Anatoly  would

follow  shortly.  Shcharansky, however, was not permitted to

emigrate, but was subsequently accused, tried and  convicted

of being a "spy" for the United States.  He was sentenced to

13 years in prison.  President Jimmy Carter,  in  an  unpre-

cedented  action  affirmed  that  Shcharansky had not been a

spy.  At the recent Helsinki meeting commemorating the  10th

anniversary  of  the  Helsinki  accord,  Secretary  of State

George Shultz again stated the United States  position  that

Shcharansky  is  being  held  in  prison  on a false charge.

Indeed, how could someone whose every move was  observed  by

the KGB, engage in espionage? Shcharansky has been subjected

to brutal treatment in prison.   Reports  are  that  he  has

angina  pectoris  and  is  also  losing  sight  in  one eye.

Because he was not permitted to receive mail from  his  fam-

ily, a right embodied in the Soviet constitution, he went on

a four-month hunger strike.  The hunger strike  was  stopped

when  his  mail  was reinstated and he was also permitted to

receive visits from his mother.


     Viktor Brailovsky, a researcher in pattern recognition,

hosted  the  weekly "Moscow Scientific Seminars" in his home

to help scientists denied access to official Soviet  science

maintain   their   professional   skills.   In  retaliation,

Brailovsky was tried and convicted of  defaming  the  Soviet

state and was sentenced to five years internal exile. A phy-

sician who visited the Brailovsky's  recently  reports  that

the family is in very poor condition.  Brailovsky's son, who

was accepted as a student at the University of Pennsylvania,

has  not  been  permitted to leave the Soviet Union.  He has

become a stutterer.  Brailovsky's young daughter was brutal-

ized emotionally by her teachers and fellow students when he

was exiled.  An extremely bright child, she now has a  read-

ing  impediment  and  impaired  vision, probably caused by a

nervous disorder.  The Brailovskys have been denied an  exit

visa on the pretext that Irina Brailovsky may have overheard

state secrets while a programmer at Moscow State University,

a  job  she lost in 1972 upon applying for emigration.  Mrs.

Brailovsky states that she never had access to  any  classi-

fied   information.   Again,  the  Brailovskys  are  another

instance of the "Catch 22" syndrome.


     Eugene Grechanovsky presented a paper  on  robotics  at

IJCAI  1983  in  Karlsruhe, Germany in abstentia.  His paper

went through the normal review process and was accepted  for

presentation.   However,  Grechanovsky was denied permission

to attend the conference.  Grechanovsky has written  several

papers  with  a  colleague,  Viktor  Kipnis,  who  has  also

requested an exit visa from the Soviet Union.


     Grigory Minc is  one  of  the  leading  researchers  in

automatic theorem proving in the well-known Leningrad group.

Again, because of his decision to emigrate he was forced  to

resign.   He  had  difficulties obtaining a job in a related

field.  However,  recently,  he  found  work  and  is  doing

research in the foundations of logic programming in the city

of Tallinn.  Minc's family life was disrupted when his wife,

faced with the prospect of the years of waiting and depriva-

tions as a refusenik, announced that she  did  not  want  to

emigrate.  The  family  has recently reconciled and his wife

now wishes to emigrate.  The move to  Tallinn,  however,  is

without his family.  Hence, it appears that to be able to do

research, he has been forced to separate from his family.


     Nadezda Fradkova wrote an  MS  thesis  in  mathematical

linguistics  in  Leningrad.   She  has  engaged  in numerous

hunger strikes in an attempt to force the government to give

her  an  exit visa.  She was forcibly removed from her home,

placed in a psychiatric hospital  and  force-fed.   We  have

recently learned that she is now serving a two year sentence

in a labor camp.


     Haim Kilov works more in the field of database research

than  artificial  intelligence.   He  has  been waiting many

years to emigrate. While he  has  been  dismissed  from  his

teaching  position  because  he seeks to emigrate, he is now

working as a researcher.


     The common thread in all of these stories is  that  the

individuals  concerned  are  Jewish  and  wish  to leave the

Soviet Union.  International treaties to  which  the  Soviet

Union  is a signatory, permit every person the right to emi-

grate from his/her country if he/she so desires.   Why  have

these  researchers  in  the  field of cybernetics/artificial

intelligence been deprived of this fundamental human  right?

They know no state secrets, have engaged in no espionage, do

not wish to change the Soviet form of government; they  sim-

ply wish to emigrate.  It is deplorable that ten years after

the Helsinki accord was signed, and  after  IJCAI  1975  was

held in Tblisi, these scientists still have not been permit-

ted to emigrate.


     The National Academy of Sciences is now engaged in dis-

cussions  with the Soviet Union to reinstate exchange agree-

ments.  I support open  exchanges  of  science  between  all

nations.  However, I would strongly urge that minimal inter-

national standards pertaining to human rights be adhered  to

by  the  Soviets  before  we engage them in other agreements

that they may not comply  with.   It  is  unclear  that  the

National  Academy of Sciences has extracted concessions from

the Soviets or have even tried to do so.


     It has also come to my attention that the Soviet  Union

has  requested that the site of the international conference

on computational linguistics for 1988 (COLING88), be held in

Yerevan,  Soviet  Armenia.   To give the Soviet Union such a

privilege without exacting a concession, is  to  essentially

say  that scientists are not interested in human rights, and

the Soviets may do what they want with our  beleagured  col-

leagues.   I  believe that if an international conference is

to be approved in the Soviet Union, several conditions  must

be  met.   First,  there  has to be written Soviet assurance

that international rules will be  followed.   Second,  there

has  to  be  a  strong Western Committee to ensure that they

will do so.  Third, scientists in computational linguistics,

cybernetics,  and  artificial intelligence who wish to leave

the Soviet Union should be granted emigration  visas  before

agreement  is  given  to the conference site. A list of such

individuals  appears in this letter.  It would be  appropri-

ate  for  any  committee  considering  such an international

conference in the Soviet Union to discuss these matters with

those who propose the conference in the Soviet Union.

     John McCarthy, Erik Sandewall and Patrick Winston  have

shown  that  it  is not necessary to compromise human rights

and scientific integrity.  I  believe  that  with  the  same

attitude,  either the Soviet Union should be rejected as the

site of COLING88, or should be made  to  comply  with  human

rights.   Should  the  Soviet Union comply with human rights

for our colleagues, I am prepared to support the site of the

Soviet  Union,  and  provide  every assistance I can to make

such a conference a success.

         The Magic of Partial Evaluation,
                      or
          Meta Interpreters for Real


                Ehud Shapiro

       The Weizmann Institute of Science



Abstract

Enhanced meta-interpreters can implement sophisticated functions within
complex software system.  Examples are explanation facilities in expert
systems, algorithmic debuggers in programming environments, and layers of
protection and control in operating systems.
However, the execution overhead of the added layer of interpretation
is unacceptable in many applications.

Partial evaluation can eliminate the overhead of meta-interpreters.
A partial-evaluator can specialize an enhanced meta-interpreter
with respect to a given program,
generating a variant of this program which inherits the enhanced
functionality of the meta-interpreter, but not its overhead.

An application of a Concurrent Prolog partial evaluator
to operating system development will be shown.

It is fine for JMC to talk about inflation being down and unemployment
being "somewhat down".  JMC will probably not be alive by the time the
true cost of the economic policies of Reagan (and of his predecessors
since Nixon or LBJ) become apparent.  I will be nearing retirement by
that time (and I am not counting on Social Security to be any help!).

I think it is very short-sighted to mortgage the future for a temporary
respite of an economic crisis.  There will be little for future
generations to do other than to curse their parents and grandparents.

John:
I've been considering writing this letter for some time now, and finally
decided to do it.   It regards a message you sent to bboard maybe two
months ago.   There was a lot of flaming about smoking going on at the time
and by chance I had the time to read some of it.   Like most people, I
enjoy reading opinions that agree with my own.   As my political views are
basically liberal, I am in the habit of typing "n" to the messages from
JMC.   At that time however, I came across a message from JMC that,
according to the header, only had ~ app. 200 characters, so I read it.
In the message you made the statement that self-rightousness is worse
than smoking.  The point of my message is simply to let you know that
I thought about this, the more I thought the more valid it seemed,
and, in fact, this brief statement significantly affected my thinking.
I wanted to let you know.
Sincerely,
Joe Karnicky

     In so far as the Freedom of Information Act goes, I agree that it
is difficult to say either way as to whether or not the government
official acted improperly.

     However, as a government official (and especially as a Reagan
appointee), he showed remarkably poor judgement to the extent that his
performance in the Department of Education is called into question.
Does his religious views cloud his performance or his actions in his
position?  Can he be expected to handle issues involving non-Christian
students (e.g. Jews, atheists, minority religions) fairly without bias?

     Also important: for all of his strong viewpoints he seems strikingly
ignorant of actual Christian theology.  He refers to "your creator, Jesus
Christ, who happens himself to be a Christian."  Should such an ignorant
man be entrusted with high government office, especially in the government
department whose ostensible purpose is to combat ignorance?

     I haven't heard of any response from Reagan about this incident, but
it should be to sack this loony.

Folks, As you know, we are expecting Senator John Glenn on Tuesday,
August 27 for a briefing on DARPA-sponsored projects at Stanford.
President Kennedy will welcome Glenn's party and stress the importance
of federally funded basic research to the nation.  Glenn has a very
tight schedule at Stanford and MUST leave by 1:00pm (1300 as we say
in the military).  People making presentations (especially those
later in the morning) should be prepared (on subtle signal from
Jim Plummer, the moderator) to shift to "Plan B," namely to give a 50% or
so shorter version of their talk--and still make it highly informative,
interesting, etc.  Jim Plummer is hoping to keep everything moving along
as per schedule, but ...  We are told that presentations should be at
the "Scientific American" level and that Senator Glenn is quite
favorably disposed toward university research.  Obviously, it's important
that he take away from this briefing the fact that some extremely
significant research is being performed at Stanford.  I'll be away
until Monday, Aug 26, but questions can be addressed to Plummer@sierra
in the meantime.  Here's the agenda:

∂10-Aug-85  1245	DEK  	diophantine equations with sums of squares  
I'm sorry I was so rushed yesterday.
If the question you asked can be phrased as "are there points in
the plane with integer coordinates such that a given set of
equalities holds between the distances between certain pairs of points"
then I guess it boils down to a special class of Diophantine equations,
which is undoubtedly well studied in the Geometry of Numbers books,
but I don't recall much about them except that the `Hasse-Minkowsi theory'
was supposed to be important.

Thanks for finding that bug; you win $2.56 for finding an error in
the answer to exercise 17.16 (page 320)!

The correct macro is
\def\sqr#1#2{{\vcenter{\vbox{\hrule    ... as before ... .#2pt}}}}

In other words, I've inserted an extra level of \vboxing.
Why? Well (somewhat to my surprise, but TeX is frozen) ---
TeX adds the \scriptspace to the width of a subscript box
(rule 18d, page 446). Since that box (without the extra \vbox)
contains an \hrule whose width was left unspecified, this
hrule was also extended by the amount of \scriptspace.
In plain TeX, \scriptspace is .5pt, so the rules above and
below the "square" were made to stick out half a point at the right.

Actually, I would argue that SAIL did the wrong thing by composing
the mail header it did.  The semantics of Reply are quite well-defined
by the network protocols these days (SAIL's implementation is perhaps
the kludgiest and should not be used as a model of how others work),
and since my mail reader filters out junk headers for me (I normally
view only "From" and "Subject") I wouldn't normally see the headers.

Anyway, I'll try and get my message on SAIL's BBoard.

I have a request from that the Japanese that we begin
the discussion with brief remarks from some of the Americans
so they know also what we are  thinking.
They have heard Sol, I have also asked Beeson and JK to say a few words.
I think we should focus on topics among the following
    (1)  extracting programs from proofs 
    (2)  on mechanical proofchecking in general 
    (3)  on mechanical checking of properties of programs 

Could you give a ten minute view of your ideas?

OK, I may say something about proof checking, but I think I'd like to say
more about commitment and related ideas.

These little talks are a diversion from the `round table' format

I would prefer you save the comments about about commitment
for a later time.


We could have a second informal session on new programming ideas
where they would fit nicely.

∂13-Aug-85  1321	VAL  	New definition of circumscription 
Assume for simplicity that we minimize one unary predicate P. We declare
p≤q (where p,q are unary predicate variables or constants) to be an additional
kind of atomic formulas. Thus ≤ is used as a "third-order constant". To
define an interpretation for this extended language, we are supposed to
interpret, among others, the new constant, which should be done by defining
a binary relation on subsets of the universe. For instance, we can interpret ≤
as inclusion, which will correspond to simple circumscription.

A circumscriptive theory is defined by two sets of axioms. One is, as usual,
A(P,Z), where Z are the symbols allowed to vary; these axioms may not contain ≤.
The other is B(≤); these may not contain P or Z. (But they may contain symbols
which function as parameters, e.g., aspects). These axioms express our assumptions
about priorities. Circumscription is defined to be

	A(P,Z) ∧ B(≤) ∧ ¬∃p,z(A(p,z)∧p<P),				(1)

where p<P stands for p≤P ∧ ¬(P≤p).

Old circumscription is the special case when B(≤) is an explicit definition of ≤.
For instance, take B(≤) to be

	∀p,q(p≤q ≡ ∀x(px ⊃ qx)).					(2)

Then in every model of (1) we have to interpret ≤ as inclusion, and we get
exactly the models of simple circumscription. Or let H be a unary predicate
(intuitively, the set of objects on which P should be minimized at higher
priority; e.g., the range of one of the aspect functions). Take B(≤) to be

∀p,q(p≤q ≡ ∀x(Hx ∧ px ⊃ qx)) ∧ [∀x(Hx ∧ qx ⊃ px) ⊃ ∀x(px ⊃ qx)].	(3)

Then we get prioritized circumscription.

But the important fact is that we don't have to make B(≤) as strong as in (2) or
(3); B(≤) doesn't have to give a complete characterization of ≤. This is because
the choice of priorities is often inessential (or in other cases some priorities
are essential and some others aren't).

Example: Let A(P) be Pa∧Pb. Instead of using (2), define B(≤) to be the
conjunction of two formulas:

	∀p,q(∀x(px ⊃ qx) ⊃ p≤q),
									(4)
	∀p,q(p≤q ∧ q≤p ⊃ ∀x(px≡qx)).

This is substantially weaker that (2); (3) satisfies these conditions as well. But
this weak B(≤) is all that is needed for the usual proof that circumscription
implies ∀x(Px ≡ (x=a ∨ x=b)).

By using (4) instead of (2) or (3), we express the idea that the choice of
priorities is inessential.

Notice that (1) depends on B(≤) monotonically. Adding new assumptions about
priorities may allow us to derive stronger results using circumscription, but we
never lose anything proved before. It appears then that it can be useful to make
B(≤) as weak as possible, to assume as little as possible about how we are going to
compare predicates. (4) seems to be close to the "absolute minimum" of necessary
assumptions.

Example: A(P) is Pa∨Pb, B(≤) is (4). Then (1) implies, as usual,

	∀x(Px ≡ x=a) ∨ ∀x(Px ≡ x=b).

If we now decide to use the stronger formula (3) as B(≤), with x=a as Hx (to
express that a higher priority is given to minimizing P on {a} than on the
complement of {a}) then we get a stronger result, ∀x(Px ≡ x=b).

Perhaps, the "simple" case of circumscription is not when it is parallel, as we
thought before. The simple case is when we don't care whether it's parallel or
not, when the database contains very few assumptions about how predicates are
compared for the purpose of minimization.

Clearly NOT USING a computer is one of the risks, and is quite properly
a subject for the forum.  Should you care to
make a comment to RISKS@SRI-CSL to that effect,
I would be delighted to include it in Vol 1 no 2.  (Sorry -- "that effect" was

John!  Hi.  As you may or may not know, I have spent the last several years
getting my MBA, working in venture capital and starting my own software
company.  I have done really well, but want to get back into research.  In
[articular, I have ideas based on the equivalence-class algorithms I
devbeloped five years ago on an alternative approach to expert systems-
production systems-rewrite rules, etc. It involves using equivalence classes
instead of syntactic objects. If I am right, it could offer an
alternative to present implementations of Prolog, etc. etc.

Anyway, I am interested in talking to whoever can make things happen
within Stanford. My goal wold be to be appointed Research Professor or
Adjunct Professor in the department on a part time basis initially (I
realize that I will have to obtain funding; Zohar has very nicely offered
tentative funding). There appears to be no problem with reappointing me
Senior Research Associate, but I am not too interested in that title.
Do you have any ideas on the above?  Would you like to get together for
breakfast or lunch sometime ?

John,

I am a member of the local arrangements committee for IJCAI.  One of my
responsibilities is press coverage and public relations.  Since you the
recipient of the research excellence award and one of the founders of the
field you are an obvious choice for participation in a press conference.
The purpose for this message is to invite you to speak at one.

It occurred to me that it would be wonderful to get your evaluation of the
impact of IJCAI 85 on the last day of the conference, Friday August 23rd.
If you have another topic you would like to address or some other day would
be better, please tell me and we can arrange it.

For your information we are holding press conferences every morning at
10:00 in the press room which will be in the West Center at UCLA, but the
time is flexible.  We plan on having two speakers each day.  The press
conferences will last about an hour and the participants may choose to
either speak together or follow one another.  Generally we expect a format
of a short statement followed by questions.

By the way, Aravind Joshi has already agreed to participate on Friday,
speaking as the program chairman.

I've tried to call several times but without much luck.  Since time is now
becoming short, I thought I'd drop you a note telling you that I am
trying to get in touch with and why.

				Thanks and congratulations on your award,

I have just read Paul Asente's bboard message, and I saw yours (JMC's)
earlier, and am in the uneviable position of being grateful to both of
you. I took no offence at your message, and your assumption that I was
unfamiliar with BBOARD is both reasonable and stated in such a way to
give me the benefit of the doubt. The main point you make about use of
the net is something I appreciate very much, and in fact I have felt
the stanford BBOARD a most worthwhile forum. Your own contributions
are always of interest for an intelligent and reasoned statement of
views with which I often disagree. The tradition of free speech and
open discussion of sensitive issues is a source of hope for us all.

Paul is also a good friend, and his suggestion is a good one.  I will
be rewording any statement with a view to being clear, inoffensive
(except that my position itself may be so), and with the absolute
minimum of disruption to the conference (which is not after all on
foreign policy).

I am not yet making any replies to BBOARD, but you may forward this or
request me to do so if you feel it appropriate for minimizing
animosity on the net.

My opinion : I think it's appropriate for you to make a very short comment 
about this topic during your speech, but to use up all your speech time 
for this purpose would be highly inappropriate.

However, during the press conference, you could spend as much time as you wish 
on this issue.

While refuting the claim that ".... is impossible", please do present
a complete picture ... ie, your position on the feasibility of SDI,
whether today's expert systems are in a position to do SDI, whether
you think anything like today's expert systems will be in a position
to do SDI in say, ten years' time, etc.

John McCarthy: I argue CPSR's approach is reasonable as follows:

1) I assume you admit that bugs in the SDI software would be very
   bad since this could quite conceivably leave our cities open
   Soviet attack.

2) You concede software verification theory does not permit proof
   of correctness of such complex programs.  I concede this same
   theory does not show such proofs are impossible.

3) The question to responsible computer professionals then becomes:
   From your experience in developing and debugging complex computer
   systems, how likely do you believe it is that currently possible
   efforts could produce error-free software, or even software whose
   reliability is acceptable given the risks in (1) ?

Clearly answering (3) requires subjective judgements, but computer
professionals are among the best people to ask to make such 
judgements given their expertise.  

I think it would be rather amusing if you told the press what you
told bboard: that you "hope they can get it to work".

I completely agree with you that those opposing SDI based on computer
science *principles* are in error.  However, I believe there's a germ
of truth to what they claim.  I think it's their computer science
*experience* (or perhaps more accurately, programming experience) that
leads them to believe that the programs used in an SDI system would be
have too many bugs to be safe.  And given the state of the art of
programming and verification, I'd agree with them.  Moreover, based on
my (admittedly not that well-informed) perceptions of how quickly
these areas are advancing, I'd say it will be decades (at least)
before they reach the point at which I'd have confidence that an
SDI system would work flawlessly.

And I think the CACM paper by DeMillo, Lipton, and Perlis (Social
processes and proofs of theorems and programs) is particularly
important here.  Although I don't agree with everything they say,
their central thesis (as I remember it), that we'd really want more
than just some verification system claiming that SDI works, is
especially true when it comes to something as important as SDI.

Although I don't think it's impossible, I think it's highly unlikey
(say, p < .05) that we could build a working SDI system with
reasonable funding levels (say, what is currently being proposed),
within the next 20 years, that would have a reasonably small
probability of seriously malfunctioning (say, p < 1/100,000 per year).

Since I don't know enough about SDI to make good judgments about what
appropriate values are for various "reasonable" parameters, I'm not in
a position to give an informed opinion about how we should proceed
with it and how much we should fund it.  But I think it's important
that some well-informed people make some honest, objective estimates
(well, as objective as possible) before spending huge amounts of
money.  My gut feeling is that, unfortunately, this won't happen,
whichever way it turns out (if I had to guess, I'd say that probably
there's too much political opposition for SDI to get very far).

use that as an opportunity to take copious notes for questions
they would later ask you during the press conference.

during your speech, i would certainly hope you would raise all of
the issues you mentioned with respect to these so called "claimed
authorities" of computer science principles on task impossibility
and that you repeat your statement that "you hope it can be made
to work."

when/where will you be receiving this award?  anywhere in the bay
area or is this something that will be part of IJCAI?

One of my friends at NTT, Hiroshi G. Okuno, is an expert at this long route.
(Hiroshi G. Okuno "hplabs!kddlab!nttmecl!ntt20!okuno"@utah-cs)

[PLAN]
1. We will soon have a direct link between Shasta (STANFORD) and NTT
Laboratory which replaces the long route. NTT will poll Shasta every day
through dial-up.

2. The CSNET executive committee will discuss the question of a Japanese
gateway at their next meeting, on September 30. If they decide to go
ahead, we will have a CSNET site in Japan.

Dear Dr. McC -

In response to your BB announcement:

1.  Given that IJCAI is by and large a forum for hucksters and crackpots
of various types, it is probably a poor  choice of venue for the
delivery of thoughts which you'd like taken seriously by serious
folks.

2. Ditto, for tying your pro-SDI arguments in with "AI"; it can only
lower the general credibility of what you have to say.

3.  You are certainlyu right that no-one can now prove that the creation of
effective SDI software is mathematically impossible, and that part of your
argument is beyond reproach, even if rather trivial.  However, you then
slip into the use of the word "impractical", which is a very different
thing, with entirely different epistemological status.  On this point,
you may well be entirely wrong -- it is an empirical matter, of course.


I take no personal stand on the desirability or otherwise of SDI, but
as a citizen I have a vested interest in seeing some discussions of
the subject that are not too heavily tainted by personal bias and
special pleading.

I applaud your intent to make a statement.  I feel the issue at hand is
an ethical one:  it's distinctly unethical to make specious claims of SDI
technical infeasibility.  I believe you're unusually well-qualified [on the
basis of your work] to make such a statement, which need not be as brief
as some have suggested.

Two relevant fragments come to mind:
	DoD hasn't been supporting research on self-correcting and -repairing
	code and on program specification methods and languages just to support
	someone's hobby interests,

	Until it was actually done (X-1), a substantial "authoritative" 
	portion of the AE and physics communities were quite agitated at
	"waste" of public $ to attempt supersonic flight which, after all,
	"couldn't be done".

I think that the specification of a scheduling program with the
postponability heuristic as control will correspond to a specification
of a standard algorithm in OR (using PERT charts) which isolates
critical paths first and solves them. 
Any constraint satisfaction problem which has an ordering on the
criticality of its constraints (like ABSTRIPS) can be specified
as logic + postponability heuristic for control.

I didn't want to comment on this to you.  I think though that you
misunderstand the objections.

The problem isn't if SDI works.  If SDI turns out to be the ultimate
defensive weapon that guarantees complete security, then it is a good
thing.  Everybody should have it.  It would be great if Nicaragua had
their own SDI system to defend against US attack (especially an
extended SDI that also defends against conventional forms of attack).
War would be eliminated.

Of course, that would preclude revolutions as well, as the governments
controlling the SDI systems could presumably use them to defend against
the revolutionaries.  I fear that you and I have different viewpoints
as to which of the current revolutions would improve and which would
degrade the governments in question should they succeed.  I think there
is some agreement that in some cases a revolution is needed to overthrow
a government that it unsuited to the needs of its people.

However, this isn't the problem.

If SDI does not work, if it is not the ultimate defensive weapon, then
it is merely another weapons project.  If it doesn't work at all, then
it is a waste of billions of taxpayer dollars.  I can think of more
important things for my share of the cost of SDI...such as my current
attempts to buy a house.

If SDI only partially works, then it is a new weapon, another step in
the arms race.  Only now it's been expanded further.  Would SDI technology
in fact make offensive nuclear assault even more deadly than it is now?
Perhaps.

Maybe free peoples are a bit jaded of hearing politicians claim that a
certain weapons technology is the ultimate that will ensure lasting peace.
Maybe free peoples have decided that politicians are either ignorant or
mendacious when it comes to weapons technology.

While I too have been frequently annoyed that messages to lists have
some copies returned, I can understand the rationale -- that if your
message did not arrive within the time you normally expect, the system
should notify you; it might matter to you.  In fact, these messages seem
to get thru eventually, so I just delete these notices.

Maybe all mail programs should have a low-priority flag to tell the
system not to get excited so easily.  However, I do not see where
arrogance is involved.

Questions for JMC:
1.  Have you ever been involved personally in a software project involving
    20 or more programmers?  How about 100?  1000?
2.  Do you personally KNOW anyone who has been involved personally in a
    software project involving 20 or more programmers?  How about 100?  1000?
3.  If so, did the software EVER reach the state that it just worked
    correctly without ongoing human tinkering?
4.  Can you imagine that NASA would ever dream of sending its programmers
    on vacation during a space flight?
With SDI in place, we might as well send the programmers on vacation because
they won't have time to fix anything.  "Infeasible" means "impracticable"
or "intractable," not "impossible."  We are talking about the real world,
the real pentagon, the real defense contractors and lobbyists.  Anyone who
looks at the F-20 mess is bound to be pessimistic about the quality of
any decisions in their hands.

To: su-bboard@SU-CSLI.ARPA, jmc@SU-AI.ARPA

  All of this talk about proving that sdi meets its specifications has got
me thinking about program proving in general.  JMC's argument seems to
hinge on the theory that it is always possible (in theory at least) to tell
whether or not a program meets its specs.  Drawing analogy to the halting
problem, I'm not sure that this is the case.

  Assume that we have a machine M which accepts a specification and a
program (machine description) and says Yes iff the program meets the
specification.  Now take the specification S=``Program P s.t. M(S,P)=No''. 
Taking *any* program Q, it seems to me that M cannot say anything one way
or another about S and Q (if we assume Q doesn't meet S, then M says no in
which case Q meets S so M says yes in which case...).

  The only reasonable conclusion I can draw from this is that there is no
machine that can accurately check any program against any spec (or
alternatively that there exist specifications which cannot be checked by
any program).  

  Of course, this is a pathological example, but SDI is going to be an
awfully complex program with horrendously complicated specs.  It hardly 
seems farfetched to think that something as nasty as this (if not as blatent) 
might be embedded in them somewhere.

Nils:
     Since you have been out of town for the past couple of weeks, I wanted
to bring you up to date on plans for Glenn's visit here next Tuesday. As you
know, the briefings are set to start at 8:30 AM in the main conference room
in the CIS building. Glenn will arrive with about 8 staff members by limo at
8:30. Don Kennedy will be here to greet him and to provide some introductory
remarks. 
     As you are well aware, the agenda is VERY tight since Glenn will be
leaving by limo for Moffet Field at exactly 1 PM to catch a 1:30 flight. There
is virtually no slop in the schedule to allow for speakers going over their
allotted time. I have arranged for a catered lunch to be brought in just before
noon. There will be plenty of food for all the speakers. We will have a 
working lunch, as called for in the agenda.
     Because of the VERY tight schedule and because of the importance DARPA
places on this visit, I have gone over the content and points of emphasis of
each of the DSO related talks. I think that high quality visual aids and
well formulated thoughts are essential if the presentations are to go smoothly.
(Incidentally, Dick Reynolds has requested that all speakers provide copies of
their visual aids before their talks. I have asked the DSO related speakers to
bring 20 copies.) Dick is also planning on being here at Stanford on Monday to
go over the talks of each of the DSO speakers (Plummer, Harris, Quate and
Spicer). I don't know if any similar plan exists for the IPTO related talks,
but I think that such coordination would really make the overall presentation
much more effective.
     Please let me know if there is anything that I can do to help you in
coordinating the IPTO related talks. I think that all of us will benefit from
a successful review.
                                               Jim

My continuing as workshop-approver
Pat,
	As you probably know, I have been serving as workshop-approver
at Woody's request.  I started approving them when I was President.  I
am agreeable to continuing, but I consider myself serving "at the pleasure
of the President".  Would you like me to continue?

	I have been considering the requests entirely informally and
have been authorized to approve up to $10K but typically $5K.  When I
approve I copy Claudia and the current President.  So far all the proposals
for genuine workshops have come from qualified people and I have approved
all of them.  There have been some proposals for supporting large conferences
or other non-workshops on which I have passed the buck to the President.
Also I have done a certain amount of pump-priming and suggested that certain
people organize workshops, since the number of proposals is far smaller
than it ought to be.

	I have imposed no specific rules on the form of workshop.  The
organizer may establish whatever procedure he chooses for selecting
papers and participants and may provide a proceedings if he wishes.

There follows a proposal that I will approve forthwith
if you authorize me to continue the program.

John,
  I'm starting to organize a small, informal workshop on analytical
methods for machine learning (e.g. the application of constraint-back
propagation, derivation-based generalization supported by a TMS, etc.)
The idea would be to have 2 intensive days and a small number of
participants (less than 20) who are actively working on this new
approach -- about 1/2 faculty & 1/2 graduate students. 

  My question is whether you think this would be appropriate for AAAI
sponsorship.  The budget would be modest, say 6K, as it would be held
at University premises.  But, it definitely would not be open to the
public, or even all AAAI members.  So, this might disqualify it.

To: RISKS@SRI-CSL
From: Peter G. Neumann <Neumann@SRI-CSL>

I was away during the previous three weeks, which made it difficult to put
out another issue.  However, the newspapers were full of excitement relevant
to this forum:

  * A Federal district judge awarded $1.25 million to the families of
    three lobstermen who were lost at sea in a storm that the National
    Weather Service failed to predict because its parent organization 
    (the National Oceanic and Atmospheric Administration) had not repaired 
    a weather buoy for three months.  [NY Times 13 Aug 85]

  * Another Union Carbide leak (causing 135 injuries) resulted from a 
    computer program that was not yet programmed to recognize aldicarb
    oxime, compounded by human error when the operator misinterpreted
    the results of the program to imply the presence of methyl isocyanate
    (as in Bhopal).  A 20-minute delay in notifying county emergency
    made things worse.  [NY Times 14 and 24 Aug 85 front pages]  (There
    were two other serious Union Carbide incidents reported in August as 
    well, although only this one had a computer link.)

  * An untimely -- and possibly experiment-aborting -- delay of the intended 
    25 August launch of the space shuttle Discovery was caused when a
    malfunction in the backup computer was discovered just 25 minutes 
    before the scheduled launch.  The delay threatened to seriously
    compromise the mission.  [NY Times 26 August 1985]  The Times reporter
    John Noble Wilford wrote, "What was puzzling to engineers was that the
    computer had worked perfectly in tests before today.  And in tests after
    the failure, it worked, though showing signs of trouble."  Arnold
    Aldrich, manager of the shuttle program at Johnson, was quoted as saying
    "We're about 99.5% sure it's a hardware failure."  (The computers are
    state of the art as of 1972 and are due for upgrading in 1987.)  A
    similar failure of just the backup computer caused a one-day delay in
    Discovery's maiden launch last summer.

  * More details are emerging on possible computer hanky-panky in elections,
    including the recent Philippine elections.  There has been a series of
    articles in the past weeks by Peter Carey in the San Jose Mercury News
    -- which I haven't seen yet but will certainly hope to report on.

I expect that future issues of this RISKS forum will appear at a higher
frequency -- especially if there is more interaction from our readership.  I
will certainly try to redistribute appropriate provocative material on a
shorter fuse.  I hope that we can do more than just recapture and abstract
things that appear elsewhere, but that depends on some of you contributing.
I will be disappointed (but not surprised) to hear complaints that we
present only one side of any particular issue, particularly when no
countering positions are available or when none are provoked in response; if
you are bothered by only one side being represented, you must help to
restore the balance.  However, remember that it is often easier to criticize
others than to come up with constructive alternatives, and constructive
alternatives are at the heart of reducing risks.  So, as I said in vol 1 no
1, let us be constructive.

Subject: Mariner 1 irony
To: risks@sri-csl

My late father (Otto R. Spies) was a research scientist at Burroughs when
the Mariner 1 launch failed. He brought home an internal memo that was
circulated to admonish all employees to be careful in their work to prevent
similar disasters in the future. (I don't recall whether Burroughs was
directly involved with Mariner 1 or not.)  After explaining that a critical
program bombed because a period was substituted for a comma, the memo ended
with the phrase

		"... no detail is to [sic] small to overlook."

My father would be deeply pleased that people who can fully appreciate this
small irony are now working on ways to prevent the misapplication of
computers as foible-amplifiers.

Thanks for the copy of Vol. I, No. 1.  Herewith a brief reaction.  This

digest is appropriate for inclusion in the digest.  

  1. Please mung RISKS so that it does not break standard undigestifying

   (a.) You cast your net altogether too widely, and include some topics
        that have been discussed extensively on widely-read mailing lists.
        Star Wars, the Lin paper, the Parnas resignation, and related topics

        doubt about the utility of replicating this discussion.  (The
        moderators of HUMAN-NETS and POLI-SCI have both adopted the policy
        of directing SDI debate to that forum.  Would it be a good idea to
        follow that example?

           [To some extent, yes.  However, one cannot read ALL of the
            interesting BBOARDs -- there are currently hundreds on the
            ARPANET alone, many of which have some bearing on RISKS.  Also,
            browsers from other networks are at a huge disadvantage unless
            they have connections, hours of spare time, money, etc.  This is
            a FORUM ON RISKS, and should properly address that topic.  We
            certainly should not simply reproduce other BBOARDS, but some
            duplication seems tolerable.  (I'll try to keep it at the end
            of each issue, so you won't have to wade through it.)  By the
            way, I had originally intended to mention ARMS-D in RISKS vol 1
            no 1, but did not have time to check it out in detail.  For those

   (b.) You do not cover the topics which, in my opinion, are going
        to generate more law-making than anything you do touch on.  In
        particular, the health hazards (if any) of CRT use, and the working
        conditions (including automated performance testing) of "pink-collar" 
        CRT users are going to be among the most important labor-relations
        issues of the next few years.  Many people think these more imminent
        risks than those mentioned in the RISKS prospectus.

                              [Fine topic!  PGN]

  3. I think a digest is an animal that differs considerably from print
     media, but is no less important.  I get the feeling that you consider
     yourself a country cousin of the ACM publications and of SEN.  Wrong!
     You're not inferior, you are just editing in a different medium and as 
     you put your mind to the task, I hope you come to take them with a
     larger grain of salt.  In particular, 

      !  Chinese computer builder electrocuted by his smart computer after he 
         built a newer one. "Jealous Computer Zaps its Creator"!  (SEN 10 1)

     was a National Inquirer-style joke.  The editor of SEN should not have
     reprinted it, and you probably should not have included it in a
     serious list of computer-related failures.
        [The editor of SEN has sometimes been known to indulge in levity.  
         In this case it appears that a Chinese engineer was indeed
         electrocuted -- and that is an interesting case of computer-related
         disaster.  On the other hand, if someone can believe that an
         AI automatic programming routine can write many million lines of
         correct code, then he might as well believe that a smart computer
         system could express jealousy and cause the electrocution!  
         Actually, Bob used "PEN" throughout rather than "SEN", but
        "Software Engineering Notes" was the only sensible interpretation
        I could come up with, so I changed it.  Do I have a "PEN" pal?  PGN]

  4. It seems to me that it is precisely in the area of serious hardware
     and software failures that RISKS should make its mark.  Directing
     itself to that topic, it fills a spot no existing list touches on
     directly, and treats a matter that concerns every computer
     professional who is earning a decent living.  Litigation about
     defective software design and programming malpractice will be the
     inevitable consequence of risks, and RISKS is the only place to
     discuss avoiding them.  Please consider focussing the list more closely
     on that subject.

        [Bob, Thanks for your comments.  I heartily agree on the importance
         of the last item.  But, I do not intend to generate all of the

From: Scott M. Rose <rose@uw-bluechip.arpa>

I had kind of hoped that somebody would submit something on the recent problem
  in Aurora Illinois, whereby a computer cable was cut that brought
  information from RADAR sensors to the regional air traffic control center
  there.  Supposedly, the system was designed to be sufficiently redundant to
  handle such a failure gracefully, but this turned out not to be the case:
  there were several close calls as the system went up and down repeatedly.
  There was information about the problem in the New York Times and the
  Chicago Tribune, at least... but not in very good detail.

I wonder if the forum is the right format for such a group.  The problem is
  that one may find oneself reluctant to report on such an incident that was
  widely reported in the popular press, and was current, for fear that a dozen
  others have done the same.  Yet in this case, the apparent result is that
  NOBODY reported on it, and I think such an event ought not pass without
  note on this group.  I might propose something more like the info-nets 
  group, where postings are automatically forwarded to group members.  If
  problems arose, then the postings could be filtered by the moderator... say,
  on a daily basis?  Just an idea...

                reported an interesting event before you go to any

	Richard Streeter's bytes got bitten by an "Arf Arf," which isn't
a dog but a horse.
	Mr. Streeter, director of development in the engineering department
of CBS Inc. and home-computer buff, was browsing recently through the
offerings of Family Ledger, a computer bulletin board that can be used by
anybody with a computer and a telephone to swap advice, games or programs -
or to make mischief.  Mr. Streeter loaded into his computer a program that
was billed as enhancing his IBM program's graphics; instead it instantly wiped
out the 900 accounting, word processing and game programs he had stored in
his computer over the years.  All that was left was a taunt glowing back
at him from the screen: "Arf! Arf! Got You!"
"HACKERS" STRIKE AGAIN
	This latest form of computer vandalism - dubbed for obvious reasons
a Trojan Horse - is the work of the same kind of anonymous "hackers" who
get their kicks stealing sensitive data from government computers or invading
school computers to change grades.  But instead of stealing, Trojan Horses
just destroy all the data files in the computer.
	Trojan Horse creators are nearly impossible to catch - they usually
provide phony names and addresses with their programs - and the malevolent
programs often slip by bulletin-board operators.  But they are becoming a
real nuisance.  Several variations of the "Arf! Arf!" program have made
the rounds, including one that poses as a "super-directory" that
conveniently places computer files in alphabetical order.
	Operators have begun to take names and addresses of electronic
bulletin-board users so they can check their authenticity.  When a
computer vandal is uncovered, the word is passed to other operators.
Special testing programs also allow them to study the wording of
submitted programs and detect suspicious commands.
INTERFACER BEWARE
	But while Al Stone, the computer consultant who runs Long Island
based Family Ledger, has such a testing program, he says he didn't have time
to screen the "Arf! Arf!" that bit Mr. Streeter.  "Don't attempt to run
something unless you know its pedigree," he says.
	That's good advice, because the computer pranksters are getting more
clever - and nastier.  They are now creating even-more-insidious programs
that gradually eat away existing files as they are used.  Appropriately
enough, these new programs are known as "worms".

Subject: Software engineering and SDI

[FROM Soft-Eng Digest         Fri, 23 Aug 85       Volume 1 : Issue  31]

Dr. David Parnas has quite accurately pointed out some of the dangers inherent
in the software to be written for the Strategic Defense Initiative.  I must
take exception, however, to the following statement from the Boston Globe
story quoted in Volume 1, Issue 29, of this digest:

        "To imagine that Star Wars systems will work perfectly
         without testing is ridiculous.  A realistic test of the
         Strategic Defense Initiative would require a practice
         nuclear war.  Perfecting it would require a string of such wars."

There are currently many systems which cannot be fully tested.  One example
is the software used in our present defense early warning system.  Another
example, one with which I am personally familiar, is the Range Safety Command
Destruct system at Cape Canaveral Air Force Station.  This system provides
the commands necessary to destroy errant missiles which may threaten populated
areas; I wrote most of the software for the central computer in this system.
The system can never be fully tested in the sense implied above, for to do so
would involve the intentional destruction of a missile for testing purposes
only.  On the other hand, it must be reliable:  a false negative (failure to
destroy a missile which endangers a populated area) could cause the loss of
thousands of lives; a false positive (unintentional destruction of, say, a
Space Shuttle mission) is equally unthinkable.  There are many techniques
available to produce fault-tolerant, reliable software, just as there are for
hardware; the Range Safety system was designed by some of the best people at
NASA, the U. S. Air Force, and several contractors.  I do not claim that a 
failure of this system is "impossible", but the risk of a failure, in my
opinion, is acceptably low.

"But ANY risk is too great in Star Wars!"  

I knew someone would say that, and I can agree with this sentiment.  The only
alternative, then, is not to build it, because any system at all will involve
some risk (however small) of failure; and failure will, as Dr. Parnas has 
pointed out, lead to the Ultimate Disaster.  I believe that this is what Dr.
Parnas is hoping to accomplish:  persuading the authorities that the risk
is unacceptable.

It won't work.  Oh, perhaps it will in the short run; "Star Wars" may not 
be built now, or ever.  But sooner or later, some system will be given 
life-and-death authority over the entire planet, whether it is a space 
defense system, a launch-on-warning strategic defense system, or something 
else.  The readers of this digest are the present and future leaders in
the field of software engineering.  It is our responsibility to refine the
techniques now used and to develop new ones so that these systems WILL be
reliable.  I fear that some first-rate people may avoid working on such
systems because they are "impossible"; this will result in second-rate
people working on them, which is something we cannot afford.  This is NOT 
a slur at Dr. Parnas.  He has performed an invaluable service by bringing
the public's attention to the problem.  Now it is up to us to solve that
problem.

I apologize for the length of this message.  The above views are strictly
my own, and do not represent my employer or any government agency.

Subject: Trip Report: Computing in Support of Battle Management

[This is a relatively long report, because I haven't been able to come
up with a simple characterization of an interesting and informative day.]

Background:

On August 13 I travelled to Marina del Rey to spend a day with the
U.S. Department of Defense Strategic Defense Initiative Organization
Panel on Computing in Support of Battle Management (DoD SDIO PCSBM).

SDI is the "Star Wars" antiballistic missile system; PCSBM is the panel
Dave Parnas resigned from.

I wasn't really sure what to expect. As I told Richard Lau when he
invited me to spend a day with them, I'd read what Parnas wrote, but
hadn't seen the other side.  He replied that the other side hadn't been
written yet. "Come on down and talk to us. The one thing that's certain
is that what we do will have an impact, whether for good or for ill."

Summary:

The good news is that the panel members are not crazies; they aren't
charlatans; they aren't fools. If a solution to SDI's Battle Management
Software problem can be purchased for five billion dollars (or even
ten), they'll probably find it; if not, they'll eventually recognize
that it can't.

The bad news is that they realize they don't have the expertise to
solve the problem themselves, or even to direct its solution. They
accept Dave Parnas's assessment that the software contemplated in the
"Fletcher Report" cannot be produced by present techniques, and that
AI, Automatic Programming, and Program Verification put together won't
generate a solution. Thus their invitations to people such as myself,
Bob Balzer, and Vic Vyssotsky to come discuss our views of the state
and prospects of software technology.

I think a fair summary of the panel's current position is that they are
not yet convinced that the problem cannot be modified to make it
soluble. ("Suppose we let software concerns drive the system
architecture? After all, it is one of the two key technologies.") They
are trying to decide what must be done to provide the information that
would be needed in the early 1990s to make a decision about deploying a
system in the late 1990s.

Assumptions:

Throughout the day's discussions, there were repeated disconnects
between their going-in assumptions and mine. In fairness, they tried to
understand the sources of the differences, to identify their
assumptions, and to get me to identify and justify mine.

* Big budgets: I've never come so close to a trillion-dollar ($10**12)
project before, even in the planning stage. ("The satellite launches
alone will cost upwards of $500 billion, so there's not much point in
scrimping elsewhere.")

- I was unprepared for the intensity of their belief that any technical
problem could be steamrollered with a budget that size.

- They seemed surprised that I believed that progress in software
research is now largely limited by the supply of first-rate people, and
that the short-term effect of injecting vastly more dollars would be to
slow things down by diverting researchers to administer them.

* Big software: They were surprised by my observation that for every
order of magnitude in software size (measured by almost any interesting
metric) a new set of problems seems to dominate.

- This implies that no collection of experiments with million-line
"prototypes" can ensure success in building a ten-million-line system.
I argued that the only prototype from which they would learn much would
be a full-scale, fully-functional one. Such a prototype would also
reveal surprising consequences of the specification.
(The FIFTEENTH LAW OF SYSTEMANTICS: A complex system that works is
invariably found to have evolved from a simple system that works.)

- Only Chuck Seitz and Bijoy Chatterjee seemed to fully appreciate why
software doesn't just "scale up" (doubtless because of their hardware
design experience). It is not a "product" that can be produced at some
rate, but the design of a family of computations; it is the
computations that can be easily scaled.

* Reliability: I had assumed that one of the reasons Battle Management
software would be more difficult than commercial software was its
more stringent reliability requirement. They assume that this is one of
the parameters that can be varied to make the problem easier.

Discussion:

The Panel is still in the process of drafting its report on Battle
Management Systems. Although they take the need to produce such a
system as a given, almost anything else is negotiable. (In particular,
they do not accept the "Fletcher Report" as anything more than a
springboard for discussion, and criticize current work for following it
too slavishly. The work at Rome Air Development Center--which produced
estimates like 24.61 megalines of code, 18.28 gigaflops per weapons
platform--was mentioned contemptuously, while the Army work at Huntsville
was considered beneath contempt.)

The following comments are included merely to indicate the range and
diversity of opinions expressed. They are certainly not official
positions of the panel, and--after being filtered though my
understanding and memory--may not even be what the speaker intended.
Many of the inconsistencies are real; the panel is working to identify
and resolve them.

- The problem may be easier than a banking system, because: each
autonomous unit can be almost stateless; a simple kernel can monitor
the system and reboot whenever a problem is detected; there are fewer
people in the loop; more hardware overcapacity can be included.

- If you lose a state it will take only a few moments to build a new
state. (Tracks that are more than 30 minutes old are not interesting.)

- Certain kinds of reliability aren't needed, because: a real battle
would last only a few minutes; the system would be used at most once;
with enough redundancy it's OK for individual weapons to fail; the
system doesn't have to actually work, just be a credible deterrent; the
system wouldn't control nuclear weapons--unless the Teller "pop up"
scheme is adopted; the lasers won't penetrate the atmosphere, so even
if the system runs amok, the worst it could do would be to intercept some
innocent launch or satellite.

- We could debug the software by putting it in orbit five or ten years
before the weapons are deployed, and observing it. We wouldn't even
have to deploy them until the system was sufficiently reliable. Yes,
but this would not test the important modes of the system.

- Dependence on communication can be minimized by distributing
authority: each platform can act on its own, and treat all
communication as hints.

- With a multi-level fault-tolerance scheme, each platform can monitor
the state of its neighbors, and reboot or download any that seem to be
malfunctioning.

- In fifteen years we can put 200 gigaflops in orbit in a teacup. Well,
make that a breadbox.

- Space qualification is difficult and slow. Don't count on
microprocessors of more than a few mips in orbit. Well, maybe we could
use fifty of them.

- How much can we speed up computations by adding processors? With
general-purpose processors, probably not much. How much should we rely
on special-purpose space-qualified processors?

- Processor cost is negligible. No, it isn't. Compared to software
costs or total system costs it is. No, it isn't, you are
underestimating the costs of space qualification.

- 14 MeV neutron flux cannot effectively be shielded against and
represents a fundamental limitation on the switching-speed, power
product. Maybe we should put all the computationally intensive
components under a mountain. But that increases the dependence on
communication.

- Maybe we could reduce failure rates by putting the software in
read-only memory. No, that makes software maintenance incredibly
difficult.

- Flaccidware. It's software now, but it can become hardware when
necessary.

- Is hardware less prone to failure if switched off? Maybe we could
have large parts of the system on standby until the system goes on
alert. Unfortunately, the dominant hardware failure modes continue even
with power off.

- The software structure must accommodate changes in virtually all
component technologies (weapons, sensors, targets, communication,
computer hardware) during and following deployment. But we don't have
much technology for managing rapid massive changes in large systems.

Relation to Critics:

Dave Parnas's criticisms have obviously been a matter of considerable
concern for the panel. Chuck Seitz and Dick Lau both said explicitly
that they wouldn't be satisfied making a recommendation that failed to
address the issues Dave and other critics have raised. Chuck also
distributed copies of "The Star Wars Computer System" by Greg Nelson
and David Redell, commending it to the attention of the panel as
"Finally, some well-written and intelligent criticism."

Richard Lipton had a somewhat different attitude: How can they say that
what we are going to propose is impossible, when even we don't know
yet what we're going to propose? And why don't software researchers
show more imagination? When a few billion dollars are dangled in front
of them, the physicists will promise to improve laser output by nine
decimal orders of magnitude; computer scientists won't even promise one
or two for software production.

The minutes of the August 12 meeting contain the following points:

- Critics represent an unpaid "red team" and serve a useful function in
identifying weak points in the program.

- Critiques should be acknowledged, and areas identified as to how we
can work to overcome these problem areas.

- Throughout our discussions, and in our report we should reflect the
fact that we have accepted a degree of uncertainty as an inherent part
of the strategic defense system.

- How to get the system that is desired? This basic problem goes back
to defining requirements--a difficult task when one is not quite sure
what one wants and what has to be done.

Prospects:

After all of this, what do I think of the prospects for SDI Battle
Management Software? I certainly would not be willing to take on
responsibility for producing it. On the other hand, I cannot say flatly
that no piece of software can be deployed in the 1990s to control a
ballistic missile defense system. It all depends on how much
functionality, coordination, and reliability are demanded of it.

Unfortunately, as with most other computer systems, the dimension in
which the major sacrifice will probably be made is reliability. The
reality of the situation is that reliability is less visible before
deployment than other system parameters and can be lost by default. It
is also probably the hardest to remedy post facto. Of course, with a
system intended to be used "at most once," there may be no one around
to care whether or not it functioned reliably.

Despite these misgivings, I am glad that this panel is taking seriously
its charter to develop the information on which a deployment decision
could responsibly be based.

I was taking [as?] my model Petr Beckmann's book "The Health Hazards of not

the very large number of deaths resulting from conventional energy sources
from, e.g. mining and air pollution.  It seemed to me that your announcement
was similarly one sided in its consideration in risks of on-line systems and
ignoring the possibility of risks from their non-use.  I won't be specific
at present, but if you or anyone else wants to make the claim that there are
no such risks, I'm willing to place a substantial bet.

   [Clearly both inaction and non-use can be risky.  The first two items at

From: John McCarthy <JMC@SU-AI.ARPA>
Subject: IJCAI as a forum   
To:   su-bboards@SU-AI.ARPA 

	Like Chris Stuart, I have also contemplated using IJCAI as a forum.
My issue concerns the computer scientists who have claimed, in one case "for
fundamental computer science reasons" that the computer programs required
for the Strategic Defense Initiative (Star Wars) are impossible to write and
verify without having a series of nuclear wars for practice.  Much of the
press (both Science magazine and the New York Times) have assumed (in my
opinion correctly) that these people are speaking, not merely as
individuals, but in the name of computer science itself.  The phrase "for
fundamental computer science reasons" was used by one of the computer
scientist opponents.

	In my opinion these people are claiming an authority they do not
possess.  There is no accepted body of computer science principles that
permits concluding that some particular program that is mathematically
possible cannot be written and debugged.  To put it more strongly, I don't
believe that there is even one published paper purporting to establish
such principles.  However, I am not familiar with the literature on
software engineering.

	I think they have allowed themselves to be tempted into
exaggerating their authority in order to support the anti-SDI cause,
which they support for other reasons.

	I have two opportunities to counter them.  First, I'm giving
a speech in connection with an award I'm receiving.  Since I didn't
have to submit a paper, I was given carte blanche.  Second, I have
been asked by the local arrangements people to hold a press conference.
I ask for advice on whether I should use either of these opportunities.
I can probably even arrange for some journalist to ask my opinion on
the Star Wars debugging issue, so I wouldn't have to raise the issue
myself.  Indeed since my position is increasingly public, I might
be asked anyway.

	To make things clear, I have no position on the feasibility
of SDI, although I hope it can be made to work.  Since even the
physical principles that will be proposed for the SDI system haven't
been determined, it isn't possible to determine what kind of programs
will be required and to assess how hard they will be to write
and verify.  Moreover, it may be possible to develop new techniques
involving both simulation and theorem proving relevant to verifying
such a program.  My sole present point is that no-one can claim
the authority of computer science for asserting that the task
is impossible or impractical.

	There is even potential relevance to AI, since some of the
opponents of SDI, and very likely some of the proponents, have suggested
that AI techniques might be used.

	I look forward to the advice of BBOARD contributors.

Subject: Verifying SDI software
To: su-bboard@SUMEX-AIM.ARPA

John McCarthy: I argue CPSR's approach is reasonable as follows:

1) I assume you admit that bugs in the SDI software would be very
   bad since this could quite conceivably leave our cities open
   Soviet attack.

2) You concede software verification theory does not permit proof
   of correctness of such complex programs.  I concede this same
   theory does not show such proofs are impossible.

3) The question to responsible computer professionals then becomes:
   From your experience in developing and debugging complex computer
   systems, how likely do you believe it is that currently possible
   efforts could produce error-free software, or even software whose
   reliability is acceptable given the risks in (1) ?

Clearly answering (3) requires subjective judgements, but computer
professionals are among the best people to ask to make such 
judgements given their expertise.  

I think it would be rather amusing if you told the press what you
told bboard: that you "hope they can get it to work".

I thank those who advised me on whether to say something about the
SDI controversy in my lecture or at the press conference.  I don't
presently intend to say anything about it in my lecture.  Mainly
this is because thinking about what to say about a public issue
would interfere with thinking about AI.  I may say something or
distribute a statement at the press conference.

I am not sure I understand the views of those who claim the computer
part of SDI is infeasible.  Namely, do they hope it won't work?  If
so, why?  My reactionary mind thinks up hypotheses like the following.
It's really just partisanship.  They have been against U.S. policy
in many areas including defense, that they automatically oppose any
initiative and then look for arguments.

McCarthy is making a classic error of criticizing something that 
he has not read.  I have not argued that any program cannot be written 
and debugged.  I argue a much weaker and safer position, that we cannot
know that the program has been debugged.  There are "fundamental computer
science reasons" for that, they have to do with the size of the smallest
representation of the mathematical functions that describe the behaviour
of computer software and our inability to know that the specifications
are correct.

Dear Dr. M

	A friend of mine, whose principal weakness is reading the junk mail 
posting on bulletin boards sent me a copy of your posting with regard to 
SDI.

	It is in general a foolish error to criticize a paper that you have
not read on the basis of press reports of it.

	Nobody has, in fact, claimed that any given program cannot be
written and "debugged" (whatever that means).  The claim is much weaker,
that we cannot know with confidence that the program does meet its
specification and that the specification is the right one.  There is both
theoretical (in the form of arguments about the minimal representation of
non-continuous functions) and empirical evidence to support that claim.  The
fact that you do not read the literature on software engineering does not
give you the authority to say that there are no papers supporting such a
claim.

	As I would hate to see anyone, whether he be computer scientist or AI
specialist, argue on the basis of ignorance, I am enclosing ...

To: jmc@SU-AI.ARPA

Dear Dr. McC -

In response to your BB announcement:

1.  Given that IJCAI is by and large a forum for hucksters and crackpots of
various types, it is probably a poor choice of venue for the delivery of
thoughts which you'd like taken seriously by serious folks.

2. Ditto, for tying your pro-SDI arguments in with "AI"; it can only lower
the general credibility of what you have to say.

3.  You are certainly right that no-one can now prove that the creation of
effective SDI software is mathematically impossible, and that part of your
argument is beyond reproach, even if rather trivial.  However, you then
slip into the use of the word "impractical", which is a very different
thing, with entirely different epistemological status.  On this point,
you may well be entirely wrong -- it is an empirical matter, of course.


I take no personal stand on the desirability or otherwise of SDI, but
as a citizen I have a vested interest in seeing some discussions of
the subject that are not too heavily tainted by personal bias and
special pleading.

         Feasibility of Software for Strategic Defense
                    Panel Discussion

        David Parnas, University of Victoria
           Moderator: Manny Lehman, Imperial College

This panel will discuss the feasibility of building the software for the
Strategic Defense System ('Star Wars') so that that software could be
adequately trusted to satisfy all of the critical performance goals.  The
panel will focus strictly on the software engineering problems in building
strategic defense systems, considering such issues as the reliability of the
software and the manageability of the development.

    [This should be a very exciting discussion.  Fred has extensive hardware,
     software, and management experience from his IBM OS years.  David's
     8 position papers have been widely discussed -- and will appear in the
     September American Scientist.  We hope to be able to report on this
     panel later (or read about it in ARMS-D???).   Perhaps some of you
     will be there and contribute your impressions.  PGN]

From an article in Technology Review by Herbert Lin on the difficulty
(impossibility) of developing software for the Star Wars (Strategic
Defense Initiative) system:

  Are there alternatives to conventional software development?  Some defense
  planners think so.  Major Simon Worden of the SDI office has said that

    "A human programmer can't do this.  We're going to be developing new
     artificial intelligence systems to write the software.  Of course, 
     you have to debug any program.  That would have to be AI too."

Subject:  @=  Can a computer declare war?

****************** CAN A COMPUTER DECLARE WAR?

Below is the transcript of a court hearing in which it is was argued by the
Plaintiff that nuclear launch on warning capability (LOWC, pronounced
lou-see) unconstitutionally delegates Congress's mandated power to declare
war.

The Plaintiff is a Londoner and computer professional motivated to act by
the deployment of Cruise missiles in his hometown.  With the advice and
endorsement of Computer Professionals for Social Responsibility, on February
29, 1984, he filed a complaint in propria persona against Secretary of
Defense Caspar Weinberger seeking a declaration that peacetime LOWC is
unconstitutional.  The first count is presented in full below; a second
count alleges a violation of Article 2, Part 3 of the United Nations Charter
which binds the United States to settle peacetime disputes "in such a manner
that international peace and security, and justice, are not endangered":

1.  JURISDICTION:  The first count arises under the Constitution of the
United States at Article I, Section 8, Clause 11, which provides that "The
Congress shall have Power ... To declare War"; and at Article II, Section 2,
Clause 1, which provides that "The President shall be Commander in Chief" of
the Armed Forces.

2.  Herein, "launch-on-warning-capability" is defined to be any set of
procedures whereby the retaliatory launching of non-recoverable nuclear
missiles may occur both in response to an electronically generated warning
of attacking missiles and prior to the conclusively confirmed commencement
of actual hostilities with any State presumed responsible for said attack.

3.  The peacetime implementation of launch-on-warning-capability is now
presumed constitutional, and its execution by Defendant and Defendant's
appointed successors is openly threatened and certainly possible.

4.  Launch-on-warning-capability is now subject to a response time so short
as to preclude the intercession of competent judgment by the President or by
his agents.

5.  The essentially autonomous character of launch-on-warning-capability
gives rise to a substantial probability of accidental nuclear war due to
computer-related error.

6.  Said probability substantially surrenders both the power of Congress to
declare war and the ability of the President to command the Armed Forces,
and launch-on-warning-capability is therefore doubly repugnant to the
Constitution.

7.  The life and property of Plaintiff are gravely jeopardized by the threat
of implementation of launch-on-warning-capability.

WHEREFORE, Plaintiff prays this court declare peacetime
launch-on-warning-capability unconstitutional.

chance he will.  He'll talk with Charlie Smith Tue. am; and if Charlie is
positive, Peter will then call Nils with a list of suggested people to get

a pretty suitable start, it strikes me.)

Peter asked that we send him a lot of detail about all the Stanford Benefits---
medical, retirement, housing, etc. ---which I take as a good sign.  I'll 
get this done.

I enjoyed your talk. The map coloring example is nice. Although map
colouring is technically "hard" your little algorithm makes it easy
on many (most?) real maps. It inspired me to think again about
the constraint satisfaction paradigm as it applies to maps -
a nice  thesis in there somewhere. It also connected in with

Hi...

A number of us have been thinking about having a Renaissance Thanksgiving
feast for a few years now.  I am sending out this initial message to see
if there is any general interest in putting on a dinner of this scope and
type.

Basically, we would have committees of "volunteers", each committee being
assigned to one aspect of the dinner preparation.  I have thought of the
following committees:

	  Food
	  Drink
	  Entertainment
	  History
	  Dancing
	  Costumes
	  Games, and, of course,
	  Set-up and Clean-up

We can have the dinner at my house, although if there are enough people,
we could rent a room such as the Great Room at the Morgan House in LAH.
My guess at the expense would be $15-$25 per person, and we should probably
make a "student rate" for all of you bona fide students (no graduate student
emeriti allowed...).

I anticipate that we would have a veritable renaissance feast, with dancing,
games, entertainment (juggling, plays, music, etc.), and that the dinner
would take most of the day (and night?)  For the sake of finals, we think
that the dinner should be mid-November.

If you're interested, send mail to M.MU at LOTS, or A.SANDY@HOW.  The dinner
will involve some WORK, time, and study to make it happen--if you sign up,
you should be prepared to really participate.

				 Sandy


P.S.  The mailing list which sent this message was a fairly random attempt
at finding likely interested parties.  If you know of someone who would like
to participate, please feel free to send them this message.

Following are the proposed texts of three letters to be sent out asking
for recommendations for candidates for our robotics position.  Reviewing
our conclusions at the last robotics search meeting, we decided to send
out three letters.  One letter specifically asks for an evaluation of
Latombe.  (He is the only general AI, non-vision, applicant, and we
decided that it would be inappropriate to ask people to compare him with
vision people. Also, we want an evaluation of his leadership abilities.)
One letter specifically asks for an evaluation of Will.  (He is the only
candidate so far that we would consider giving a non-tenured appointment
as a research professor.)  We do want an evaluation of his leadership
abilities, but we don't think it appropriate to ask people to compare
him with Latombe (they are in different fields).  The other letter asks
for an evaluation and comparison of Horn, Zucker and Goad.  Their
connection to robotics is through vision research.  We decided that none
of these candidates is high on our list for robotics leadership, but
that they all could be compared as vision researchers/professors.

After the letters, I have begun a list of people with whom we might
compare our candidates.  We will have to be careful to include
appropriate names with each letter.  Comments on the letters and on the
comparison list are solicited.

Letter One:  Possible non-tenured/Leadership:  Will

Dear ...

We are currently conducting a search for a leader of robotics research
at Stanford.  The appointment could be either as a tenured professor or
as a non-tenured "research professor."  Our need is for someone who is
not only a creative contributor to research in his or her own right but
is also capable of leading what we expect to be a growing research team.
We have narrowed our search to the point where we have a serious
interest in Dr. Peter Will.  As part of our search process we
solicit opinions of the candidate from distinguished people like
yourself.  Could you please write us a candid letter about him?  Of
course, your response will be kept confidential and will be seen only by
senior faculty and cognizant administration officials.

An essential part of our search process is specific comparison with a
list of the world's leading individuals in the candidate's field or
fields.  I attach a list of such people chosen from among those who are
at approximately the same stage in their careers or perhaps somewhat
more senior.  We hope that you will add to this list if you deem it
warranted, and we are especially interested in knowing if you perceive
any women or minority group members that belong on this list.  To add
protection to your anonymity, you may refer to the people on our list by
the code numbers indicated if you desire.

We hope that your letter will address as many of the following questions
as are relevant:

-  How well do you know him and in what capacity?
-  How would you characterize his ability to carry out his own creative and
   significant research?
-  Can you cite some of his specific achievements and their overall 
   importance?
-  How would you characterize his ability to lead and inspire creative
   and significant research among the members of a research group?
-  What basis is there for expecting him to make significant contributions to
   the literature?
-  How would you assess his ability:  in teaching and curriculum development?
   in advising students?  in supervising dissertation research?
-  What is his potential for continued growth in teaching and research?

We would like a balanced evaluation including comments on any weak points
as well as strong points.  We enclose a copy of his vita in case
that would be of help to you.

We know that we are asking for a very big favor of one whose schedule is
already crowded.  It is extremely important for Stanford to have your
advice, and I want to thank you in advance for your help.  We hope we
will be able to have your response by ....

Sincerely,

W. Jones (Johns?) from Monitor radio never called back so I still have
your tape. Did you hear from him?

∂03-Sep-85  1707	JJW  	Some restored files to be deleted 
The restoration of files after last week's disk crash on SAIL caused some
extra files in your directory to be restored, namely those that existed at
the time of a full system dump done in July and were later deleted.  As
far as we can tell, the files listed below fall into this category.  Feel
free to delete these now if you no longer need them.  Otherwise, send a
message to JJW@SAIL if you want any of them preserved.  All of the listed
files will be deleted by September 7 if you do not indicate that you want
any kept.

The files to be deleted are the following:


Note: if you have files to be deleted in more than one directory, you
will receive a separate message for each such directory.

∂04-Sep-85  0236	JJW  	Files to be deleted
To:   "@FILES.DIS[1,JJW]"@SU-AI.ARPA  
Regarding the messages sent yesterday:

1. If you want to maintain control over your own files, please send me a
   message and I won't delete anything.  In fact, I'd like to encourage
   this since it distributes the work.  If the list of files you want to
   delete is long, the following procedure may be of use:

   a. Put the list of filenames into a file by itself without an E
      directory (use /N mode), one name per line.  Edit out the names of
      any files that you want to preserve.
   b. Type the monitor command DELETE @filename, where "filename" is
      the name of the file containing the list of names of files to
      be deleted.  This will delete all files in the list.

2. A mistake in the lists has been pointed out, and will be corrected.
   Files that were written before the crash, and renamed to their current
   names since the crash, were erroneously included in the lists.  This
   will be avoided by only considering files that existed at the time of
   the full save done in July as well as now, but did not exist at the
   time of the crash, and were last written before the crash.

∂05-Sep-85  1616	VAL  	Abstract for Halpern's conference 

	Circumscription As A Solution to the Frame Problem

   The frame problem consists in describing how the properties of objects change
across events. To solve it, we should formalize the Generalized Law of Inertia:
"Generally, things remain as they were".

   The first idea is to state this in terms of minimization:
"The difference between the values of a fluent in two situations separated by an
event is minimal, subject to the given properties of the event".

   What do we mean by "difference" here? If the fluent is predicate-valued, like
"on", then the difference is the extension of the exclusive OR applied to the two
values of the fluent. Thus we minimize the extensions of predicates, so
circumscription is relevant.

   To give a simple example of how this works, consider the blocks world in
which a block can be in one of only two places: on the table or on the floor.
The language will be more limited than that of situation calculus: we have
variables for blocks only, not for events or situations. Two unary predicates
ontable and ontable', will be used to talk about the positions of blocks in
two situations separated by an event. Axioms:

	Bi≠Bj (1≤i<j≤6); ontable Bi (1≤i≤3); ¬ontable Bj (4≤i≤6).

Let the event consist in putting B4 on the table. That is expressed by ontable' B4.
The frame problem consists in deciding which of ontable' Bi are true for i≠4. Add
the axiom

		¬ab x ⊃ (ontable x ≡ ontable' x),

and circumscribe ab with ontable' varied. The result is: ab x ≡ x≠B4, which is
exactly what we needed.

   We want to do this sort of things for more complex versions of the blocks world,
and for the language with variables for events and situations. In situation
calculus, a fluent is represented by a predicate p(x,s), where x is a tuple
of arguments, and the law of inertia for p can be expressed by

	-ab(x,e,s) ⊃ (p(x,s) ≡ p(x,result(e,s))).

Unfortunately, this doesn't quite work, at least in the blocks world in which
one can move blocks on top of one another, because there may be a conflict
between minimizing ab(x,e,s) for different situations s, and we get some
minimum values of ab which don't correspond to the picture we want to
formalize. (I'll check whether describing the simple version of the blocks
world above in the language of situation calculus already causes problems, or
they arise only for more complex versions).

   There are two ways out: (i) state that the action is impossible when the
preconditions aren't satisfied; (ii) state that abnormality now should be
minimized at a higher priority than abnormality later. Only (i) has been
explored so far, and it seems to work.  (I hope I'll have something to say
about (ii) by the time the full paper is due.) In this solution, since
"result" is a total function, some situation terms fail to denote possible
situations. We view the universe as containing the concepts of situations
rather than situations themselves, and introduce the predicate "exists" to
talk about the possibility of actions. For this formalization, we can prove
that the minimal point is unique and satisfies some conditions which show
that it is what we would intuitively expect.

Just want to report that during a year of intensive TV watching in Munich,
I saw only two Stanford luminaries, one of whom was you.  You speak
extremely fluent German, except that somehow you use a totally different
voice when speaking German than when speaking English.  (Also, you're
able to continue talking after your lips stop moving).

The other Stanford luminary was Edward Teller, who seems to be on German
TV weekly, explaining (in real German) why SDI will make all our lives
richer and happier.

John, I have been trying to clean out old files on the 5th floor, and have
been going through old SAIL files from the Lab.  I am able to determine
what should be kept with regard to finances, grant and contract files, etc.,
but I have three or four boxes which contain your papers, etc.  Is it o.k.
for me to have them brought to your office so you can go through them to see
what you want to save?

Also, there are still boxes of yours up there which need going through.  I
understand that some time ago, when Carolyn Tajnai was working here in the

Can we start doing this again?

	 The question of responsibilities for non-use of computers are
	 largely meaningless in terms of law unless the dangers of
	 non-use were known to substantially increase the probability
	 of greater harm. In the case of your three short examples:

	 (1) If the ACLU had acted in good faith in seeking to limit
	 sharing of police information and a court had looked favorably
	 on their argument after weighing the possible risks, then the
	 court is responsible because only the judge had the ability to
	 decide between two courses of action. To make the ACLU
	 responsible would be to deny it and its point of view access
	 to due legal process. To make it necessary for the ACLU to
	 anticipate the court's response to its bringing suit would
	 have the same chilling effect on our legal system.

	 (2) The same argument applies to the Sierra Club and US 101.
	 If US 101 had been built and then some people were killed, one
	 could as easily conclude that the Sierra Club (or anyone else)
	 might be sued for NOT obstructing the highway!

	 (3) The "Split Wood not Atoms" poster-vendor might be sued if
	 it could be conclusively proven that he was a knowing party to
	 a conspiracy to give people lung cancer. But we might assume
	 that his motivation was actually to prevent a devastating
	 nuclear accident that might have given 10,000 people lung
	 cancer...

	 Again, a risks-of-computers organization can only present its
	 case to court and people and, so long as no malfeasance is
	 involved, cannot be held responsible for its failure to
	 predict future consequences. There are far more important
	 "unsymmetric" relationships than that of the press vs. the
	 legal system that pertain to issues of responsibility, namely,
	 that of past vs. future and known vs. unknown. I feel that you
	 are correct in pointing out how computer people would do well
	 to apply their expertise to solving problems of society. In
	 this case the moral imperitives are quite clear.

    	The problem with a forum on the risks of technology is that
    while the risks of not using some technology, e.g. computers, are
    real, it takes imagination to think of them....

You raise an interesting point that deserves more discussion.
However, as one who is concerned that the major problem arises from an
uncritical acceptance of technology, I strongly disagree with your
suggestion that the scales are stacked AGAINST those who are
"pro-technology".  The reason that anyone adopts any given technology
is that it provides benefits that he can see; the problem is getting
those individuals to see that there are costs as well.  In other
words, the bias in the system is towards acceptance of technology, not
rejection of it.  It is this general bias that "risks" people are
trying to correct.

    ...Is a risk-of-computers
    organization that successfully sues to delay a use of computers either
    MORALLY or LEGALLY LIABLE if the delay causes someone's death?  Is there
    any moral or legal requirement that such an organization prove that they
    have formally investigated whether their lawsuit will result in killing
    people?  As the above examples indicate, the present legal situation
    and the present publicity situation are entirely unsymmetric.

There are such precedents; organizations can be held liable for using
technology that that is not as up to date as is "generally
applicable".  On the more general point, it is much harder to
establish liability as the result of someone's inaction as compared to
the result of someone's action; this does happen, but it is harder to
prove. 

    The harm caused by tape-to-tape batch processing as opposed to on-line
    systems.

I like this example; let's have more discussion of it.  There was a
time when on-line systems were totally unreliable, but I think that
time has past.

    Shouldn't computer professionals
    who pretend to social responsibility take an interest in an
    area where their knowledge might actually be relevant?

This is a cheap shot unworthy of pioneers in computer science.  More
than anyone else, computer professionals are the ones who are in the
best position to assess the limits as well as the promises of
technology.  You once said that the responsibility of the scientist is
to take his science whereever it may lead.  I agreed with you then,
and I agree with that now.  But science is part of a social and
cultural context, and cannot be separated as cleanly as one might
imagine.  If it is proper for the developers of science and technology
to propose new applications of their work (because they see these
potential applications as beneficial to society), it is also
appropriate for them to suggest possible consequences of their use as
well.

    ... In my opinion, any organization
    that intervenes legally has at least the moral responsibility to prepare
    a statement about the impact of their intervention, including the impact
    of delays they may cause.

I concur entirely.

    Specifically, the Sierra Club had a responsibility
    to attempt to estimate the likely effect on traffic fatalities of success
    in their attempt to delay making U.S. 101 south of San Jose into a freeway.
    They were successful, and I think the ten year delay killed some tens
    of people.

On the specifics of this case, how can it be established that it was
the 10 year lack of freeway that killed these people?  Any suggestions
that you have on how one makes an analytical case for this claim would
be welcomed.

To: pednault@SRI-AI.ARPA

Consider the following situation calculus sentence which puts one
of your metamathematical results into the formalism itself.

Here  S0  is an initial situation.
u, u1,u2 are variables for sequences of actions.
achieves(u,s,g) means that  u  achieves  g  starting in situation  s.
preserves(u,s,g)  means that  u  preserves  g  starting in situation  s.
result(u,s)  is the situation that results from action sequence  u  starting
in  s.
on(A,B)  is logically an object but represents an assertion, i.e.  on(A,B)
is a proposition.

(u)(achieves(u,S0,on(A,B) and on(B,C))
implies
(E u1)(E u2)(u = u1 append u2
& achieves(u1,S0,on(B,C))
& achieves(u2,result(u1,S0),on(A,B))
& preserves(u2,result(u1,S0),on(B,C)))).

From suitable axioms expressing some of the assumptions of your paper,
this would be a theorem of the language and hence something that the
system might derive while learning how to build towers of blocks.

I have some other remarks about how the power of your heuristics might
be improved.

[In reply to message rcvd 08-Sep-85 13:43-PT.]

Having compared our drafts, I realized that the difficulty you're talking
about is different from the one I described. In your draft, you consider
minimizing "on"; for me, this is inessential. (Incidentally, contrary to
para. 2 of your draft, in the axiomatization of (McCarthy 1984) there are
no axioms saying that it is abnormal for an object to be on another. And
such axioms are probably not necessary for correctly describing the results
of actions, as long as "on" is allowed to vary, because the axiom saying
that move(A, top B) is normally possible will imply then that top A and top B
are clear).

The difficulty considered in my draft consists in the conflict between maximizing
inertia for two successive actions, whereas you look at a single action.

If, for some reason, we want to minimize "on", that should be done at
a lower priority than minimizing the impossibility of move. That will
apparently solve your problem.

It seems to me that this is not the right example for illustrating the
need to assign priorities on the basis of mental states.

Your comments regarding the generality of my language vis a vis the
situation calculus are absolutely correct.  However, the two
formalisms are equivalent when the problem specification is restricted
to include only an initial-state description, a goal description, and
a description of the allowable actions.  With regard to situation
variables, yes, introducing situation variables in predicates can be
very useful.  In fact, I introduce situation variables in proving the
equivalence between my language and the situation calculus, given the
above restrictions, and in formulating the keyes and boxes problem,
where situation variables are used in simulating nondeterministic
actions via incomplete knowledge of the initial state.

Given the nature of your comments, I should emphasize that I have not
attempted to construct the most general framework possible.  One theme
that keeps cropping up in my work is that a problem can be solved
efficiently only if it has properties that facilitate problem solving.
In constructing my framework, I have tried to balance the degree of
generality against the degree to which there exist exploitable
properties.

I will be out of town from the 17th to the 26th.  A good time to meet
would be either the 16th or sometime after the 26th.

In my equivalence proof, I introduce a new constant symbol
CURRENTSTATE that denotes the current state of the world.  In
translating from the situation calculus to my framework, the initial
state description is simply the set of axioms given in the situation
calculus formulation, plus an axiom defining CURRENTSTATE.  For each
action in the situation calculus formulation, a action schema is
introduced whose effect is to change the denotation of CURRENTSTATE.
Thus, for the putonred(x) action, we would introduce a schema
putonredaction(x) defined as follows

	putonredaction(x)

		UPDATE: CURRENTSTATE <-- result(putonred(x), CURRENTSTATE)

That is, the new current state is the result of performing putonred in
the previous current state.  The effects of putonred(x) are
axiomatized in the initial state description in the usual manner.

Note that this proof does not say how to best translate from the
situation calculus to my framework, it only shows that it is possible.

The 1985 Workshop on Distributed Artificial Intelligence will be
held from December 3-6 at Sea Ranch, a shoreside resort two hours'
drive north of San Francisco.

Cost will be $150 per person, which includes accomodation for the nights
of the 3rd, 4th and 5th and food at Sea Ranch.  Accomodation is two to
a room; if you have a preference, state it!  A few rooms have also been
reserved for the night of the December 6, should anyone want to stay on
over the weekend.  The additional charge will be approximately $100 per
room per night.

Anyone interested in attending should send the money,
together with either an extended abstract or a complete paper,
to either of the organizers at:

		Department of Computer Science
		Stanford, California  94305

This material should be received no later than November 1; all papers
received will be available in preprint form at the conference, and the
best will be selected to be included in a forthcoming collection of papers
on DAI.

Details on format and local arrangements will follow.  At moment, we
are planning to have sessions on a variety of topics (dictated by the
papers we receive) and to finger various people to comment on the
papers in each session.  Maybe a panel or two, and we certainly hope
to leave enough free time for plenty of unstructured discussion.

Support for the Workshop has been received from AAAI.

To:   JMC@SU-AI.ARPA, CLT@SU-AI.ARPA, RPG@SU-AI.ARPA,
      Fateman@UCB-VAX.ARPA  
I reached Steve Squires at DARPA today and received different guidance (again)
on how to proceed.  They now wish to fund Qlisp as a task on the existing
contract with Stanford.  When I asked what the limitations are on size, it
sounded as though about a year's funding can be gotten through; conceivably
two years'.  This is a lower committment level than we would like but it is
better than fiddling around with no funding.  Squires says that he can turn
around and get money to us in about 60 days.

I propose to carve off the first year of the original proposal, including
the hardware buy, and send it via ARPAnet with a request for informal
concurrence, then get the formal submission to them as soon as possible.
Does anyone have reservations about proceeding in this way or have a
better idea?

∂10-Sep-85  1500	VAL  	monadic predicate logic 
In case you are still interested in implementing the normal form for monadic
predicate logic: I learned from Weyhrauch's paper in the AI Journal about
FOL that FOL has the procedure MONADIC for deciding monadic formulas. Maybe
it uses something like your normal form.

∂10-Sep-85  1637	LES  	Qlisp tasking 
To:   JMC@SU-AI.ARPA, CLT@SU-AI.ARPA, Fateman@UCB-VAX.ARPA
Having now reviewed the contract under which the proposed task would be assigned,
I find that there appears to be no problem with the amount of money but the
performance period of the contract ends on 5/31/87.  In view of that, it
appears that we can get away with an 18 month proposal: say, 12/1/85 - 5/31/87.
It is conceivable that the contract can be extended to encompass the entire
project but it would probably be best to close the first funding before
trying to open that door.

I have a question about your claim concerning the equivalence of your

Take this action: "put block x on a red block". (Assume for simplicity that
this is always possible). In situation calculus, we can describe its effect by

	(Exists y)(red(y) and on(x,y,result(putonred(x),s))).

How can we express this in your language?

We are trying to make more effective and equitable use of our space
this year, and are consequently doing some remodeling and
rearrangement of offices.  Part of the scheme involves reassigning
offices for researchers housed in the trailers to remodeled quarters
in Casita.

We plan to convert the top floor of Casita into open-door offices,
that is, offices assigned to all of you collectively rather than
individual offices assigned particularly.  The offices on the top
floor can comfortably accommodate two to three researchers at a time.
When you come to work, you can use any unoccupied desk, much as you
would at a library.  We plan to have locking storage cabinets
installed for personal belongings you'd like to leave in the building.
We've also planned a few changes to Casita which will make it a much
more felicitous place to work:

	Air-conditioning to accommodate Dlions and other
	machines

	Adding 3 or 4 new offices upstairs (making a total
	of 7 or 8 offices to be shared among, at most, 26 researchers)

	Resurfacing the walls in existing offices

	Creating a new lounge on the lower floor for either large or
	small impromptu meetings

	Adding decks between Ventura and Casita to provide
	gathering places when the weather permits


We'd like to accomplish the move before fall quarter classes begin on
September 25th. If you could try to move your personal belongings by
September 20th, our postdocs and graduate students would have time to
settle into their new surroundings before the term gets underway.  If
you have problems moving, get in touch with Jamie (Jamie@CSLI)
and he'll arrange help for you.

Space will be tight, and conditions occasionally substandard, until
construction is complete.  Until then, the upstairs offices in Casita,
except for number 55, will be yours to share.  Optimistically, the
project could be finished before the end of Fall; but, based on other
campus construction schedules, mid-Winter might be a more conservative
prediction of the completion date.  Thanks for your patience during
this time.

I have made a determined and largely successful effort not to
short-change CSLI on the time I spend their and I have profited greatly
as a result.  I have been encouraged in this by the fact that I had a
desk & a few book shelves where I could expect to find again whatever I
left there.  There was a dandytiger for the use of which Lauri and I
could establish policies that suited us.  A SYSOUT left on the disk
tonight would, in all probability be there in the morning.  It is no
good pretending that the proposed arrangement will do anything but
degrade the quality of life at Ventura.  I guess the rationale is that
we have other offices.  It is inevitable that I, at least, will will
surely spend an even larger proportion of my time in that other office
and behave essentially as though I had no working space at CSLI.  I
don't know about the rest of you, but I USE(ed) my office at CSLI for a
few hours a day on the average.  I will regretfully move my books back
here in the morning.

I have had several complaints about the new plan regarding office space
for researchers.  The purpose of this message is to offer an alternative
and solicit your preferences. 

First, let me briefly explain that the idea of having unassigned open
offices for researchers stemmed from a desire to see the available
space used more efficiently.  It was our perception that most of the
space assigned to researchers with principal offices elsewhere was
being very sparingly utilized (or, in some cases, being utilized by
non-CSLI people).  We thought this might be due to the large number
of people assigned to some of the offices, and we came up with the
idea of a pool of offices as a way of distributing usage, in the
hopes that this would lead to researchers spending more time in
offices here.  

Clearly, at least some of you think this was a bad idea.  Fortunately,
it is not too late to change the plan.  We currently have five large
offices set aside for you, and after the remodeling there will
probably be two more.  These offices could be divided up among
you, with 3-5 people assigned to each office.  Or we could proceed
with the open office plan.  It would even be possible to have a
mixture, with, say, 3 offices assigned to specific sets of people,
and 4 others available on an open basis to the rest of you. 

In order to decide among these options, I need to know what your
preferences are.  We will implement whatever plan seems to have the
most support among you.  Please let me know your opinion as soon as
possible.

As far as the Sequent is concerned, we pay the maintenance contract only.
Two people from Sequent will come next week to discuss upgrades
and beta sites for new software and hardware.
I will be glad to help you out on this. However, there may be times
when we need to run heavy jobs. In these cases, we would like to have
the machine for ourselves. 

Summarizing, you may work on our machine provided that we can
have full use of it on certain occasions. We can discuss about
sharing the cost of the maintenance.

I would not like to have the operating system to be
changed because we would like to have a stable development
environment.

Let me know if you need anything else.

Most of the talks in the planlunch series have been about "neat"
research.  While neat researchers know they have a more 
expressive formalism than do planners like SIPE, they have rarely
sat in front of a machine and watched their systems be overwhelmed
by the computational loads even simple representations can impose.

I'll defend scruffy planning (not to replace but to supplement neat planning),
show how SIPE represents a simple 6-room indoor world for Flakey, show 
its solutions and use of computation, describe the kind of hacks needed to
make things run fast, describe pitfalls, and other scruffy stuff like that.
Only a small amount of time will be spent explaining SIPE, depending on 
audience's desire.

∂12-Sep-85  1407	VAL  	Mental situations  

Example for mental situation calculus: expression evaluation

Mental fluents:


evaluated(x,ss)		in mental situation ss, expression x is evaluated
goal(x,ss)		in mental situation ss, the goal is to evaluate
			expression x
committed(x,ss)		in mental situation ss, there is a commitment to
			evaluate expression x
should(a,ss)		in mental situation ss, action a should be performed

Mental actions:

commit x		commit oneself to evaluate x
apply(f,x,y)		apply function f to the values of x,y

Mental events:

learn v			the value of v becomes known

The effect of mental actions and events:

committed(x,result(commit x,ss))
evaluated(x,ss) ∧ evaluated(y,ss) ⊃ evaluated(f(x,y),result(apply(f,x,y),ss))
evaluated(v,result(learn v,ss))

Deontic laws:

goal(x,ss) ⊃ should(commit x,ss)
committed(f(x,y),ss) ∧ ¬ evaluated(x,ss) ⊃ should(commit x,ss)
committed(f(x,y),ss) ∧ ¬ evaluated(y,ss) ⊃ should(commit y,ss)
committed(f(x,y),ss) ∧ evaluated(x,ss) ∧ evaluated(y,ss) ⊃ should(apply(f,x,y),ss)

In addition to these general rules, assume that a specific mental situation ss0
is described by:

goal(f(g(v1,v2),h(v3,v4)),ss0)
evaluated(v2,ss0)
evaluated(v3,ss0)
evaluated(v4,ss0)

The sequence of events

apply(h,v3,v4)
learn v1
apply(g,v1,v2)
apply(f,g(v1,v2),h(v3,v4))

will provably lead to the desired result, evaluated(f(...),ss). But it is not
*rational* in the sense that actions are performed when they shouldn't. More
formally, we want the term defining ss to satisfy this condition: for every
subterm of the form result(A,SS), we want to have should(A,SS). A rational
solution would look like this:

commit f(...)
commit g(v1,v2)
commit h(v3,v4)
apply(h,v3,v4)
learn v1			; this is an event, not an action, so the
				; rationality restriction doesn't apply
apply(g,v1,v2)
apply(f,g(v1,v2),h(v3,v4))

In a rational sequence of events, we never evaluate any expression that is not a

Having read his call for papers once again, I feel that, after all, it's not the
right place for a paper on the frame problem. Also I'm afraid my ideas on the
subject haven't aged enough even for a good abstract.

But I'll keep working on mental situations. What would help me at this point is
critical remarks on my axioms for expression evaluation. What would you do
differently? In what directions would you extend them? What are the right
questions to ask about them?

    	At the suggestion of Robert Jastrow, who is one of the main
    scientific defenders of SDI, I made the same point in letters to three
    Congressmen, said to be influential in the matter of SDI appropriations.

Robert Jastrow is certainly a defender of the SDI, but he has admitted
publically in his own Congressional testimony that he does NOT carry
out scientific analyses of anything related to SDI.  He hardly counts
as a "scientific defender."

  Computer Science does not contain or deal with the principles operative 
  in the writing and debugging of large, nay, HUGE, eclectic, software 
  programs.  This is the realm of Software Engineering.  By a similar token
  there is no principle of the theory of random processes that says that
  the works of Shakespeare cannot be written by 1,000,000 monkeys pounding
  1,000,000 typewriters either, in fact in principle that would be one way
  of reproducing these works.  No serious student of Shakespeare who knew
  something about random processes would propose such an undertaking, of 
  course.  A mathematician who knew nothing about typewriters and little
  about Shakespeare, however, might if Ronald Reagan pursuaded him that
  the problem should be worked by assigning 1,000,000,000,000 monkeys to
  1,000,000,000,000 typewriters.  In software engineering as well as 
  mechanical engineering there is the concept of feasibility to be considered.

  If you had a gun wouldn't you be more afraid to face a gunman with
  a bullet-proof vest than one without?  If he began deliberately to
  put this vest on as he stood before you with his gun leveled at you
  wouldn't you be inclined to fire before he got the vest on?

  You speak in the present tense but "it" does not exist!  How can
  a non-existence afford anything?  At least one of the basic questions
  is whether it can be made at all.

>The balance of terror is a bad thing.  

  Yes, and SDI would only enhance the terror.  The "civilized" world has
  no defensive answer to the terrorists in such mundane places as on airliners,
  let alone in space, and such is not in the offing.

  Whether the physics of the problem admits a good anti-missile defense

at 10.oo am. I come to Stuttgart and take you to erlangen. you will stay
here in a hotel. you give your talk at 2.oo pm in erlangen (they are quite
hot.) we spend the weekend somehow. monday morning (very early) we drive
to dassel. you stay there in anice room. on the 24th in the morning (8.45 am)
you give your talk. afterwards you are free - leave the same day or stay.
we bring you to the auirport in frankfurt or to a fasttrain to frankfurt.

of yourse, the university talks canm take longer as the talk in dassel.
there i have exactly 1 hour for you and additional 15 minutes for discussion.
(munich vanished because nobody is there that week.they hope for the next
mccarthy trip in november or the like.)
please inform me how you would like to get the money:should i book the plane
and pay from here? do you like $-bills? or deutschmark-bills? is this with
the train to suttgart ok (a faststrain which goes every ou hour)
it will cost some 40DM.

Actually, it's my understanding that the demise of slavery was due to
technological advances which made slavery economically unfeasible.  The
invention of the cotton gin, for example, made it only a matter of time
here in the US before slavery died out.  As far as cannibalism goes, I'd
say that was more caused by Western culture steam-rolling over the
cannibals.

[In reply to message rcvd 12-Sep-85 23:40-PT.]

Here is the problem I meant to solve with my axioms for expression evaluation.
We are computing the value of an expression, with the values of some variables
currently unknown (they are computed in parallel by someone else and from time
to time come to us from outside). An elementary operation consists in
applying a given function to given numbers. The control problem consists in
deciding which elementary operations to perform. The answer is, of course, simple:
if there is a subexpression f(x,y) with x, y already computed, apply f to the
values of x and y. My axioms show how we can describe this strategy in a deductive
way; they describe a trajectory in mental space which includes, at some points,
computing the values of functions. This is simpler than hill-climbing, because
my axioms explicitely tell us what should be done in a given mental situation,
rather than how to compare mental situations.

Patrick and Claudia,
	I believe this is 180 degrees contrary to the basic idea of the
confederation recommendation.  In particular, the goal was to further the
science and at the same time minimize the complexity and bureaucracy of
the AAAI.  An arrangement such as is being proposed with the CSS does not
help the science at all and only increases AAAI's complexity and
bureaucracy.
	We would consider such an arrangement on a temporary basis for an
organization as it was forming, to help get them started.  But that is not
the case here.
	If some other organization (presumably profit-making) were in the
business of running such services for organizations, I think the AAAI should
consider subscribing to that; but we definitely don't want to be IN that
business.

Actually, McCarthy didn't put these words in your mouth.  The words came
from my note, which appeared just before McCarthy's (RISKS-FORUM, Issue
10).  Moreover, I was trying to say that people *might* respond to you by
putting those words in your mouth, and then to give my own argument why
the proposition doesn't apply.

Dear Prof. McCarthy,

A few weeks ago you and Claudia Mazzetti and I were having a discussion in a
restaurant in Beverly Hills in which you said you were working on a
"parallel Lisp" that was "entirely based on queues".  At the time I jumped
to the conclusion that you meant that the control of parallelism was based
on scheduling queues.  However, some time later it occurred to me that you
may have meant more: that your parallel Lisp might use queues as its
fundamental data structure instead of (or in addition to?) lists, and that
the control regime might be some kind of FIFO scheduling of concurrency
instead of (or in addition to) recursive call-and-return.

Could you tell me a little more about what you do have in mind?  If there is
anything written on the subject I would be happy if you could send it to me,
either electronically or by U.S. Mail to:

you need 1h20'. I think the fare to Stuttgart is around 50DM.
In Stuttgart you should call D.Roesner instead of Gunzenhauser. His phone-nr.
is: 0711-2078-387 (uni) and 0711-684699. He priomised me to watch the uni-
phone until you arrive.
Please inform me concerning the amount of $ I have to give you. (You get bills,
if that is right?)
I wish you a nice flight and hope it will be an interesting trip.

John, RISKS has been straying further and further away from the computer
issues toward the boundary of the inappropriate.  Your latest message has
gotten us clearly into the political realm, and that is a no-no by ACM
groundrules, and I imagine ARPA as well.  I would encourage you to continue
a dialogue with Weizenbaum directly, but feel your latest message is not
suitable for inclusion.

Thanks for your active interest and participation.  The issues are extremely
important, and a diversity of opinion is vital.

The officers of AAAI benefit greatly from having a professionally staffed
office to handle the administrative details of our society: it allows them
to concentrate on issues that contribute to our science.

The same benefits can accrue to other organizations, whose
scientific mission is compatible with ours, but whose size may not
support a dedicated office staff.  Moreover, by pooling resources, we
may be able to sustain services that are currently uneconomical for
either of us (e.g., an on-line journal or bibliographic database).

For all these reasons, the federation idea is a worthy experiment.

JMT.

Patrick and Claudia,
	I'm feeling rather torn on this issue.  The arguments against
doing it are persuasive, but Marty Tenenbaum has correctly pointed out
that it would sure help smaller societies if we do this and perhaps we
should be magnanimous.  
	Why I didn't get a feel for was the reasons that you both
propose doing it.  It clearly will create alot of extra work.  Were your
reasons for supporting the idea simlar to Marty's, or do you see another
advantage that has not been addressed?  Since the impact will largely
be on the AAAI office, I think your input is particularly important.
	Thanks,

∂18-Sep-85  1209	SJG  	first order counterfactuals  
Dear John:

I am now findig myself confused over your remark that my counterfactual
construction (or Lewis') is not first order.  It seems that there are
two possible problems, neither of which arises:

(1)  Handling quantification within a counterfactual: "If Hitler
had ever invaded Britain, he would have captured London."

[∃t.invades(Hitler,Britain,t)] > falls(London)

This is not a problem because we can easily imagine possible worlds
where Hitler invaded Britain at some time.  In my formalism, we must
make the statement

¬∃t.invades(Hitler,Britain,t)

unprovable from when is left in our database.  Then we just look to see
whether what's left, together with ∃t.invades(Hitler,Britain,t), implies
that falls(London).

(2)  Handling quantification outside a counterfactual: "If Hitler
had ever invaded Britain, he would have captured London within a
week."

∀t.[invades(Hitler,Britain,t) > falls(London,t+7)]

Again, this does not seem to be a problem, since the assignment of a truth
value to the bracketed expression is handled by either my theory or
Lewis'.

What am I missing?

As you might have noticed, in the August listing of CS reports there was an
announcement of Volume I of the "Stanford Video Journal" consisting of 20 tapes
from Don Knuth's Problem-solving Seminar last year.  Judith Lemon, from the
Stanford Instructional TV Network, is trying to set up a second volume with
about 15 tapes on AI.  She is negotiating with IBM for funding (around $15K) to
cover production costs but the content of the tape set is undecided.  Ideas
range from taping a series of lectures from a course like CS 223A/B to trying
to capture descriptions of on-going research projects, like some groups have
already begun to do.  The benefits from doing this include financial return and
having the tapes to help deal with visitors and other educational/PR functions.
The Knuth tapes are being licensed for around $5K and the proceeds distributed
1/3 each to the School, Department, and lecturer after SITN takes their fee (I
forget how much) off the top.

So the purpose of this message is to stir up discussion -- do we want to do
this, who is interested, what should the contents be, etc.  We can worry about
consensus later.

hi john.  Now i am living here id like to start talking to you
about things which we have never had time to get deeply into
before.  Heres the opener:  why are you so hostile to the idea
of histories ( or whatever word you like to use )?  Ive noticed
this from you on many occassions, and I wonder what is behind it.
Here are some possibilities:  are any of these correct?
1. the idea is wrong, ie its a bad framework for describing
a changing world ( if so, why do you think so?)
2. its not wrong so much as unneccessary, ie the situation/action
framework supplies all descriptive power we need
3. its not such a bad idea, but its not properly worked out so
making claims for it is premature
4. as 3., but in particular it doesnt solve the frame problem or make it
any easier, so my claiming it did is wrong.
5. since there is so much more to discover about what can and cant be
done within the situations framework,  its diverting attention from
more urgent problems.


Well, id be interested in your reply.

∂24-Sep-85  1158	SJG  	counterfactual question 
To:   JMC@SU-AI.ARPA, john@SU-CSLI.ARPA, barwise@SU-CSLI.ARPA  
Could one of you possibly confirm/disconfirm my intuition on the following?
Thanks.

The example relates to the question of whether the similarity relation
between possible worlds is modular.  By this I mean that if W1 and W2 are
equally similar to our world, and W3 is less similar than W1, is W3
necessarily less similar than W2 as well?

Lewis seems to assume so, and get as a consequence that:

	[(p > r) ∧ ¬(p > ¬q)] → (p ∧ q) > r

where I have denoted counterfactual implication by >.

However, *my* intuition provides the following counterexample to this:

1.  If Bizet and Verdi had been compatriots, Satie would (still) have
    been French.  (true)

2.  If Bizet and Verdi had been compatriots, Satie and Verdi might have
    been compatriots.  (true)

3.  If Bizet, Verdi and Satie had all been compatriots, Satie would have
    been French.  (false)

What do you think?

Thanks much.

DARPA (Steve Squires) now wants us to twiddle the proposal in a slightly

He would like to deal with the funding of the Berkeley portion of the
work directly, so I plan to retain the full text of the proposal but
specify Prof. Fateman's proposal as a task to be funded separately.
The budget that we submit through Stanford will therefore cover the
Stanford work and the Lucid subcontract.

I hear a cry of anguish.

∂26-Sep-85  1557	VAL  	Mental situations and planning    

What is the relation between physical situations and mental situations in the
process of planning?

1. In every mental situation ss, we think of a certain class of situations
as the class of possible "current situations". For instance, currently A
is on top of B, and C is clear, and nothing else is assumed. (We may
consider the mental action of introducing an additional assumption about
the current situation). This is represented by the predicate
current(s,ss): s is a possible current situation in mental situation ss.

2. Similarly, we use goal(s,ss) to express that s is a satisfactory goal
situation in mental situation ss. Axiom:

	∀s(current(s,ss) ⊃ goal(s,ss)) ⊃ should(halt,ss).

3. Setting subgoals is described by means of the predicate
subgoal(s1,s2,ss):  in mental situation ss, achieving situation s1 is a
subgoal towards achieving situation s2 situation ss. Axioms:

	subgoal(s,s,ss),

	subgoal(s1,s2,ss) ∧ subgoal(s2,s3,ss) ⊃ subgoal(s1,s3,ss).

If setting subgoals is done in a reasonable way, we'll have also:

	subgoal(s1,s2,ss) ∧ subgoal(s2,s1,ss) ⊃ s1=s2.

4. We distinguish between

result(e,s) - situation which is the result of event e in situation s,

and

result(ee,ss) - mental situation which is the result of mental event e in
mental situation ss.

If e is an event, then learn(e) is the mental event which consists in learning
that e has happened.

Axiom:

	current(s,result(learn(e),ss)) ≡ ∃s'(current(s',ss) ∧ s=result(e,s')).

It implies

	current(s,ss) ⊃ current(result(e,s),result(learn(e),ss)).

Joe says he would like to move into the office with the Lisp Machine
console.  Also, he says the space committee has already assigned
some random person to the office he is currently in.
I think we should get our act together and get things assigned.
Given Joe's request which is reasonable I suggest the following
(assuming VAL is willing to move):

353  GLB + random
362  CLT + VAL
360  JJW + RTC
302  LES + IAM

This gives everyone in the group a desk and SAIL terminal
and if we get another person 360 can be used as a 
3 person student office.  We could also move the net terminal
from my office to 360.  

If this seems ok with you, I will give the proposal to LES
to make the official assignments happen.

The files should go on IGNORANT, which is the machine with the tape drive
and the bands should go on MT-ST-COAX, which is the machine with the face near
JMC's office.  The office numbers are MJH324 for IGNORANT and MJH360 for
MT-ST-COAX.  The boot band (>release-6-0.load) should be replaced.
The other band (>rel6-clean.load) is needed for new releases and should not
be damaged.  There is about 2000 blocks free on COAX which might be enough
if you grabage collect the world before you save it.  If that doesn't work,
I'll have to make the LMFS smaller.  Does that answer all your questions?
