doesn't oscillate, because a cell flips only if a majority of neighbors

lispx.lsp[w82,jmc] is a source file, and lispx.ppr and lispx.prf are the others.
I wanted to get the sort information and the facts about append entirely
into a symbolic form.  In order to do this I followed each line containing
such information by a LINENAMES that updated the line in question.  It worked,
but there are the following inelegances.

	1. I had to answer the question of whether I really meant it after
each use of LINENAMES for updating purposes, so there is a line containing
y after each such line.

	2. SORTINFO has extra lines.

	3. In the .ppr file, the command still comes out with some of the
numerical line number information instead of the purely symbolic information
that went in.

We are still having difficulty in working out the technique of the new

and they usually need to be modified as they become more programmable.

Step 47 in lispx.lsp[w82,jmc] or lispx.prf[w82,jmc] is produced by the
command below it.  Step 51 above (not in lispx.prf) was produced by
the same command with $ in place of the &.  The & was an attempt to
get it to expand flatten without again expanding flat.  How is that
to be done?  I want a mode that will use all applicable occurrences
of the line range referred to but won't expand the results of expansions.
Then I could expand all definitions in part of the formula with a
single reference to DEFINFO without danger of a loop.

lispx.ppr[w82,jmc] has the proof.  The main parts are done in

grateful if you would look at it from the point of view of style.

1. Can it be improved to reduce number of steps?

2. How should I change it as a model for CS258 students?

3. Does it suggest improvements to EKL?

In any case I plan to separate the proofs about flat from the
basic LISPX proof.

∂13-Jan-82  2136	JMC  	new bug  
To:   JK
The proof went through ok, but I decided to clean matters up by separating
the basic lisp axioms (now called lispax.lsp and lispax.prf) from the
definitions and proof peculiar to flat.  The lispax part went ok and so
did flat up to the point when I did (pretty-proof flat flat).
(save-proofs flat) had worked ok.  I got some kind of lisp error and then
tried (show) and got the error message you will find in flat.lsp[w82,jmc].
Running the proof again worked, but (show) failed again.  In the previous
lispx context, I had no trouble with (pretty-proof).

Another subject: Part of the difficulty with proving the facts about
flat   was that there is no direct way to use the premisses of an
implication in rewriting the conclusion.  If you can figure out how
to make this possible, at least two of the proofs will be more
straightforward.  In particular,

∀x y.(∀u.flat(x,u) = flatten(x)*u) ∧ (∀u.flat(y,u) =flatten(y)*u)
    ⊃ flat(x,flat(y,u)) = flat(x)*(flat(y)*u)

is obtainable as a valid formula in this way.  Perhaps  der  could do
this or try this or let the user try it.

The proof of  ∀x.listp(flatten x)  would also be more straightforward
were this possible.

∂13-Jan-82  2156	JMC  	more on bug

I tinkered with the file a bit more and changed the bug.  I added the
command that proves  ∀x u.listp flat(x,u), and this put another step
in the proof.  Again the proof ran without difficulty and produced
the desired results.  However, this time (save-proofs flat)  got into
an apparently infinite loop.

I have looked at them.  In the main you have the right facts, but they
require many changes to make them suitable for ekl proofs.  Mainly they
need to be put as much as possible in forms that can be used as rewrite
rules in which the left side is replaced by the right side.  Those that
can be used indefinitely need to be separated from those that can't such
as recursive definitions and commutativity.  Associative operations need
to be declared such.  There are also some bugs, such as leaving out the
conclusion of the induction axiom.

A partial message was sent by mistake.  Here's the whole message.

I have declared *, i.e. append, to be associative, and this seems to
work fine; it makes one of the proofs go without special appeal to
associativity.  I have advocated to Yoram that he declare + and times
to be associative also.  However, it occurs to me that declaring them
associative may cause problems in using their commutativity.  Suppose,
for example, that we want to prove  a+b+c+a = a+a+b+c.  If EKL doesn't
allow us to group the terms freely, then there will be difficulty in
using associativity.  There will also be a problem in matching
subexpressions.  It seems to me that allowing operators to be
declared associative is good and even necessary, but it imposes further
requirements on interactive theorem provers such as EKL.  These seem to
include

1. Parts designators should be able to pick out segments, e.g. b*c
should be a part of  a*b*c*d.

2. Matching the operator should try to match segments.  It is important
here whether the null segment should be considered, and this depends
on the operator.  Thus the matches of x*y*z against a*b*c*d are (nil nil a*b*c*d),
(nil a b*c*d), (nil a*b c*d), (nil a*b*c d), (nil a*b*c*d nil),
(a nil b*c*d), (a b c*d), (a b*c d), (a b*c*d nil), (a*b nil c*d),
(a*b c d), (a*b c*d nil), (a*b*c nil d), (a*b*c d nil), (a*b*c*d nil nil)
in the unrestricted case and the three without nil in the restricted case.

If an operator could be declared both commutative and associative, there
are many more considerations.

1. Ideally the expression should be represented internally by a multi-set
of arguments.  Arbitrary sub multi-sets should be designatable and
matched.

2. Because the ideal becomes very expensive, the user needs to be able
to restrict the potential matches that will be examined.  It will require
experience to determine what restrictions should be available.

A partial message was sent by mistake.  Here's the whole message.

I have declared *, i.e. append, to be associative, and this seems to
work fine; it makes one of the proofs go without special appeal to
associativity.  I have advocated to Yoram that he declare + and times
to be associative also.  However, it occurs to me that declaring them
associative may cause problems in using their commutativity.  Suppose,
for example, that we want to prove  a+b+c+a = a+a+b+c.  If EKL doesn't
allow us to group the terms freely, then there will be difficulty in
using associativity.  There will also be a problem in matching
subexpressions.  It seems to me that allowing operators to be
declared associative is good and even necessary, but it imposes further
requirements on interactive theorem provers such as EKL.  These seem to
include

1. Parts designators should be able to pick out segments, e.g. b*c
should be a part of  a*b*c*d.

2. Matching the operator should try to match segments.  It is important
here whether the null segment should be considered, and this depends
on the operator.  Thus the matches of x*y*z against a*b*c*d are (nil nil a*b*c*d),
(nil a b*c*d), (nil a*b c*d), (nil a*b*c d), (nil a*b*c*d nil),
(a nil b*c*d), (a b c*d), (a b*c d), (a b*c*d nil), (a*b nil c*d),
(a*b c d), (a*b c*d nil), (a*b*c nil d), (a*b*c d nil), (a*b*c*d nil nil)
in the unrestricted case and the three without nil in the restricted case.

If an operator could be declared both commutative and associative, there
are many more considerations.

1. Ideally the expression should be represented internally by a multi-set
of arguments.  Arbitrary sub multi-sets should be designatable and
matched.

2. Because the ideal becomes very expensive, the user needs to be able
to restrict the potential matches that will be examined.  It will require
experience to determine what restrictions should be available.

Please look at UMNOV.NS[W82,JMC].  I think the statement by Bernie Roth that

statement that it is impractical to put restrictions on Umnov if he visits
is essentially false.  I am thinking about a letter saying so either to the
Stanford Daily or the New York Times.  This is is independent of the question
of whether such restrictions are desirable.  What is your opinion?

To:   RPG, ME
My experience in running out of E convinces me that our work would be
improved by the ability to display a lot more characters.  No matter
how nicely they are arranged on the screen, there just aren't enough.

Would it be feasible, for experimental purposes, to make the E-system
interface convenient for someone who had two or even four datadiscs?

I think this is worth doing soon in spite of the current shortage of
datadisc channels, because it is relevant to the question of whether
having lots of characters is more important than having beautiful
characters.  My conjecture is that having two or four low resolution
displays will prove more valuable than having a high resolution display
with the same number of pixels unless the high resolution display is large
enough so that just as many characters can be put up non-microscopically.

∂23-Jan-82  2316	JMC  	improved string search  
To:   cl.boyer at UTEXAS-20, cl.moore at UTEXAS-20   
Here is an "improvement" on your string search whose correctness statement
might be difficult to formalize.  The algorithm is essentially that given
in your book, except for a change in the initialization to avoid updating
the table for all letters of the alphabet.  Each entry in the table includes
your (DELTA1 K) in its low order bits and an integer <search number> in its
high order bits.  When we start a new search, we update the entries
corresponding to the letters in the pattern string but with a search number
one larger than that of the last search.  We don't bother changing the
entries for letters that don't appear in the pattern string, because a
simple comparison when the letter is encountered in the text shows that
the entry is obsolete.  Only when the search number threatens to overflow
the allocated field do we go through the entire table and restart with
search number 1.

Since I don't know the literature and couldn't find a reference to this
kind of searching in Knuth vols. 1-3, this may be an old idea.

Notice that stating the correctness and the efficiency of the algorithm
requires taking into account that the algorithm may be used many times.

Universities Rebuff State Department Restrictions on Soviet Visitor
    STANFORD, Calif. (AP) - A widening dispute over the federal
government's attempt to extend anti-Soviet sanctions to academia has
lopped two universities from the itinerary of a Soviet scientist whose
specialty is robots.
    Stanford University has been declared off-limits to Nikolay Umnov
because the school refused to honor State Department restrictions on
his visit. The university said it could not successfully police a
visit, and that to make the attempt would disrupt the free environment
needed for creative work to take place.
    The University of Wisconsin followed Stanford's lead Friday, saying
it was an ''open institution.''
    Wisconsin Asssociate Dean Camden A. Coberly and professor Ali A.
Seireg said they plan to withdraw their acceptance of Umnov's visit.
That move will reduce the scientist's itinerary to Auburn University
and Ohio State University.
    But at Ohio State University, where Umnov was to spend six weeks,
professor Robert B. McGhee said Umnov would be ''welcome for two or
three days. I'd accept restrictions for a visit of that length, but
not any longer.''
    Umnov has been caught in a dispute over what visiting Soviet
scientists can see and do during a three-month scientific exchange
program that is sponsored by the National Academy of Sciences and
funded by the U.S. government.
    As part of the Reagan administration's attempt to restrict Soviet
access to U.S. technology, the State Department said Umnov couldn't
see anything not already published in open literature.
    It also said he should be restricted to mechanical theory of robotic
locomotion, with no industrial visits and no access to control units
or computer programming techniques that have given robots new
flexibility and made them more useful in the workplace.
    The measures are justified because the government is paying for the
visit, said Sue Pittman, a State Department spokeswoman. She also
cited ''possible technology transfer risks,'' an administration term
for thefts or leaks of U.S. scientific secrets.
    The restrictions reached universities hosting Soviet scholars via
letters from the national academy. As criticism of the restrictions
mounted, the NAS on Tuesday halted distribution of the letters.
    The restrictions are ''absurd,'' according to Bernard Roth, a
professor in Stanford's Department of Mechanical Engineeering.
    ''Guys in the U.S. who know something about it (robotics) learned
from the Russians,'' he said. Potential military applications are
''very small. ... I don't think anyone will win a war on the basis of
those machines. It's certainly not of critical national interest.''
    He added that nothing is being done in the field that the Soviets
''either don't already know or can easily figure out for themselves.''
    In refusing to honor the restrictions, Stanford Vice-Provost Gerald
J. Liberman said, ''We believe the best interests of American science
and technology are served by open exchanges of university research
activities.''
    He said in a letter to the NAS, ''The campus is completely open; and
the thousands of visiting scholars to campus each year have free
access to any of the university's programs. Even if we had the means
to monitor or police the activities of visitors, such actions would
drastically disrupt the academic environment which is essential in
fostering creative research endeavors.''
    Attempts to restrict visiting scientists are not new, and last
February Stanford President Donald Kennedy expressed ''grave concern''
over federal attempts to apply export controls to academic teaching
and research. He was joined in writing protests to the secretaries of
state, defense and commerce by presidents Marvin L. Goldberger of the
California Institute of Technology, Paul E. Gray of MIT, Frank H.T.
Rhodes of Cornell and David S. Saxon of the University of California.
    Kennedy told the faculty senate earlier this month the universities
had done ''sporadic negotiating'' with some agencies and had had
''skirmishes'' with others.

***************

kjk - Question foR the robotics people:  isn't Umnov in robot locomotion?
Aren't the Russians significantly ahead of us in locomotion?
What are the expected gains from RuSsian→US technology transfer vs.
US→USSR?
	In other words, do we stand to gain more than Russia from Umnov's
visit;  If so, a letper tk the State Department Informing them that they
are applying an import restriction pather than an export restriction
may be in order.
	A bried review of the status of known RuSsian work in roboticq might
be useful for clarifying the tra`eoffs.  Is anyone here willing to do that?
	Lest people get the wrong impression--I'm opposed to applying
export restrictions to academic work.  I think the State Dept is wedged.
However, a specific instance of the loss we incur from these restrictions
may do more than a thousand pages of moral, ethical, and philosphical
argument.

TAW - If the US Gov't doesn't want Umnov to know anything about 
state-of-the-art robotics, why are they letting him in??  That seems
to be the way to handle these things, as opposed to making every
US technologist in a sensitive field take Diplomacy courses.

JMC - I think that both Roth and Lieberman have made misstatements in
order to make their case stronger.  In my knowledge and Tom Binford's,
the Russians are mainly behind us in robotics.  Only in walking machines
have they done anything substantial.  Of course, they are very secretive
about what they do, and before they receive any visitor at an institute,
they determine what he may and may not be shown and what may be discussed.
Many institutes are secret and known only by Post Office Box numbers within
the country.  When people from one such institute (the Institute of Applied
Mathematics in Moscow) wanted to talk with me in 1965, they pretended to
be from a different institute.  Only later, when that institute wanted to
buy an American computer, did its existence emerge from secrecy; I never
got to visit it.

My attempts to collaborate with Ershov on MTC broke down mainly because
it was illegal for him to put scientific information in a letter except
by sending published documents.  It is illegal for a Russian to give a
foreigner written scientific information except in the form of published
books or papers.  In the 1960s, these rules were often bent, but exceptions
have been few since then.

Roth is also wrong in saying that robotics has no
military applications.  Lieberman's statement
''We believe the best interests of American science
and technology are served by open exchanges of university research
activities.'' contains the assumption that putting no restrictions
on Umnov would achieve that result.

Finally, the statement that restrictions are impractical and would
disrupt the University is phoney.  A visitor's schedule is made by
the University's "Office of Foreign Visitors", and nothing is easier
than leaving something off the schedule and notifying the Principal
Investigators of a few DoD sponsored projects that this has been done.
It doesn't prevent someone who wants to from telling all in the coffee
shop, but it would probably satisfy the State Department and have a
high probability of accomplishing what they want.

It is often argued that the Soviets can get all the information they
want by monitoring the literature.  It isn't easy to tell to what
extent this is true.  Certainly they are often behind in many areas,
and in many areas of computer science, their work is derivative - e.g.
putting on a Soviet computer systems done earlier in the U.S.  Of course,
there is the possibility that derivative work is all we hear about.
Overall, it seems that restrictions have important but random effects.
Of course, the restrictions the Soviets place on travel by their own
people are far more effective than our restrictions, but the effects
are additive.

Stanford is imposing restrictions on access to information, because the
Center for Integrated Systems will give special access to the companies
that are paying for it.  Even the Computer Forum gives special access to
its members.  The CIS has been agonizing for the better part of a year
about how best to give privileges to the 12 companies.

All the above constitutes criticism of the misstatements by Roth and
Lieberman.  There still remains the question of whether the particular
action of the State Department is reasonable.  If I had to make a
decision myself, I'd want more information about what the Russians do,
how open they have been, and what the military applications are.
On the basis of my experience and the information contained in the
article, the State Department position seems a reasonable compromise.

In contrast to this, Stanford seems to be taking an absolutist position,
and its spokesmen are inventing facts to fit the desired conclusions.
Perhaps the position is a leftover from the 1960s.

Apart from cost-benefit considerations, there is a political issue.
The AP story will be summarized in the Soviet press
as follows: "In spite of the efforts of
the mad dog Reagan to whip up anti-Soviet hysteria over the false
issue of Poland, American scientists realize the leading role of
the Soviet Union in robotics as in other fields.  They know the
Polish issue is false".  For more restricted circles,
the assurance may be offered that Comrade Umnov is politically
mature and will make certain that he gets more than he gives.

Should anyone wish to be actually constructive about exchanges
with the Soviet Union, I would suggest the following:

1. Form an estimate of what the Russians are doing in certain fields,
e.g. robotics or computer science generally.  Make a guess as to where
they are being open and where they are being secretive.  The CIA, which
works for us you know, could be asked to help; it interviews many
emigrants from the Soviet Union and has other sources of information.

2. If we decide there is something we want to know or institutions we
think we would like to visit, the State Department or the National
Academy of Sciences can bargain on our behalf.  Their bargaining will
be more effective if they get our co-operation.  Our problem will be
that very few scientists will find the Soviet Union interesting enough
for long visits.

Maybe it isn't worth the trouble, however.  Perhaps the effort
would be better spent on deciding what open Japanese publications to
translate.


Comments on the comments:  KJK wants to be sure people won't get him
wrong.  Let it be recorded that his views are orthodox.

TAW wants to know why the Government lets Umnov in at all if they want to
restrict what he learns.  Often the Defense Department wants to restrict
a Soviet visitors or argues against letting him in.  The
present case has the earmarks of one where the Defense Department opposed
the visit, and the State Department got a compromise.  The State Department is
in the business of making agreements and generally prefers admitting them.
However, the State Department is often more aware than others of
bargaining considerations.  For example, Americans were able to visit
Novosibirsk before any other foreigners including Soviet satellites in the
1960s while it was still a closed city, because the State Department had
mapped it on Pittsburgh and wouldn't let Soviets visit Pittsburgh until
Americans visited Novosibirsk.  The National Academy of Sciences likes
exchanges.  Individual American scientists like visits and don't much care
if the exchange is very uneven.  In fact, I have found it good for the ego
to be on the informative side of such conversations.  Only later do I
notice that I have learned almost nothing.

JMC - There is one consideration in favor of accepting grossly uneven
"exchanges" of information.  Our openness and even naivete has a
psychological effect on Russians.  There is some hope that it makes our
society look better, and some people believe this strongly.  However,
emigres and dissidents who have come to dislike Soviet society are
very vehement against Western naivete.  On balance, I'd bet that it's
to our disadvantage to look like suckers.

Proposal Entitled:  "An Operating System and Memory Switch for the S-1
                    Computer," John McCarthy, P.I.

A final report on this contract was apparently due at the end of
December, 1979.   It is difficult for me to determine whether John
McCarthy was actively engaged in the research, or whether Forest Baskett
and John Hennessy performed most of the research.  Anyway, I am sending
each of you a copy of the proposal.  The performance period was January 1,
1978, through December 31, 1979, and the funding totaled $304,472.

A final payment of approximately $3,500 is due Stanford from LLL, and they
won't pay until the report is submitted--15 copies of it.  If the report
is not submitted LLL could conceivably disallow the entire contract,
leaving us holding a $304K "bag."

Would you please let me have a final report just as soon as possible.  I
will have it duplicated and sent.

Thanks very much,

Betty

P.S.  The LLL delay in notifying us of the above is apparently due to their
      inability to locate their paperwork until recently--after hiring some
      consultants to get their files in order. -- Thanks again.

FACULTY STATEMENT ON SOVIET VISITORS

	We are distressed by the situation described in the attached
Associated Press story.  It gives the impression that Stanford takes an
attitqde of total opposition towards the Government's efforts to restpict
technology transfeR to the Soviet Union.  Moreover, this attitude seems to
be supported by a number of untrue statements, Namely (1) The Soviets are
ahea` of the U.S. in robotics.  (2) Robotics has no military applications.
(3) There are no possible restrictions on Soviet visitors that won't
αdisrupt the functioning of the UniveRsity.  We are further distressed that
that when the Soviet Aonsulate in SAn Francisco reported on the situation
to Moscow, this report probably re-inforced the idea in Moscow that
αAmerican protests about Poland and Afghanistan were a governmental sham
without Any support in the institutions of the country such as
universities.

	We believe that Stafford should adopt a policy tkward SoViet
visitors that balances the follkwing coNsiderations:¬

	1. Presepving the orderly functioningof the academiC processes of
reseArch, publication and teachingand avoiding the creation of a secUriti
atmosphere.

    NASA didn't get all it wanted in deep space. It lost a Venus orbiter
and a probe to Halley's comet. Other projects were scaled down or
stretched out. But, considering the bleak outlook a couple months ago,
it came out pretty well.
    The proposed budget also includes $137.5 million, $61.7 million and
$34.5 million, respectively, for continued development of three major
orbiting satellites: a space telescope, an advanced Landsat Earth
Resources payload and a gamma ray observatory; $100 million for
construction od facilities; and $1,17 billion foR research and program
management.

	Partly against my better judgment, I have allowed myself to
be interviewed by the Stanford Daily.  I don't think I said much
wrong, and the reporter called me to check, but I still can't be
sure how it will come out.  I suppose my main motivation was that
I had better let something happen, since I have been prevented by
other matters from taking any action along the lines we previously
discussed.

	I told the Daily reporter to call the rest of you who
took part in the meeting with Dean Lieberman, but, of course, I
can't be sure that he will do so.

	Here's hoping it turns out all right.

Sincerely,

I have succeeded in inducing a case of binder envy in Betty Scott.  She
wants to know the name of the binder at PARC and the name of the person
at PARC who can tell her about it.

Preliminary remark about flavors:  Having flavors may be independent of
whether we are talking about objects or quantities.  My example of vectors
and smallness referred to quantities.

come in two flavors, hairy and simple.  The hairy one takes binder tape
cassettes in three widths and cuts them to the length you specify.
The simple one uses precut 11" tapes and cannot bind books more than
about 1.5 times the thickness of JMC's flavor papers.  But it is
simpler to operate, harder to jam, and has colored tapes.  We have
both flavors at PARC.  (Xerox bought the company.)  My phone
(494 4491) will eventually ring at Linda Williams's switchboard,
which is right next to a hairy Cheshire.  I suspect she could tell
you a lot.

There's also a marvelous paper joggler into which you can put your
Dover output prior to Cheshiring, which Symbolics Inc just had to
have, until they learned it cost $600.  I think it's by FMC.  Call
the main Xerox number (494 4000) and ask for Jeannie Treichel or
Janet Moreland in Bldg 32.

1.I think we have sufficient word from ARPA to justify proceeding

2. I talked to Poole today who will call you.  He isn't making the
F5 and will propose an F4 but claims it will be cost-effective.  He
can have a proposal in about a week.

3. Are there other plausible candidates?  Should we get out an RFP?
Perhaps someone should phone D.E.C. to see if they can do better

I can't leave Stanford till 11:30 Friday, because I have a meeting at 10
concerned with using our ARPA computer money.  If it turns out you have
to leave early, pephaps I'd better go separatelY.  If I leave at 11:30
from StaffOrd, I can be at the Lab a few mifutes after 12:30 depeNding
on tpaffic.  Ju`ging by our previous trips, this should get us there
in time for the 7pm ceremonies.
