Date: Mon 9 Jan 84 13:18:31-PST
From: Jeffrey D. Ullman <ULLMAN@SU-SCORE.ARPA>
Subject: first lecture
To: CS440: ;
We are meeting at 4:15 Thursdays again.
This time, the meeting room will be MJH 352.
The first speaker is Bruce Delagi; abstract follows.
OVERVIEW AND TOPOLOGY CONSIDERATIONS FOR CONCURRENT KNOWLEDGE BASED SYSTEMS
Expert systems, a class of knowledge based systems in the field of artificial
intelligence, have demonstrated promise in solving apparently difficult
application problems. This promise, to be fully realized, requires computer
performance beyond what can be extrapolated from circuit and materials advances
alone. The program now underway (but still in the groping about phase) at
Stanford's Heuristic Programming Project is predicated on realizing the promise
by means of moderately extensive degrees of concurrancy (say a few hundred).
This concurrency is targeted to be accomplished by nesting - multiplicatively -
modest factors at each of several levels in a computational hierarchy ranging
from a supporting topology to problem level decomposition for a few target
signal understanding applications.
The talk will define some of the concepts used in the knowledge based systems
under consideration, articulate the computational hierarchy used as a framework
in the program, and tour the design space at the bottom level of this hierarchy
- together with a rationalization for the (tentative) choices made for physical
connection topology, granularity, and low-level communication / synchronization
support.

OK, Betty, here's what I suggest for dividing up the new $950K increment
on the DARPA Equipment contract (see 1/84 column below):
6/83 1/84 Remaining
Increment Increment Increment
Formal Reasoning $224,000 135,300 0
2-FCZ780 (JMC)
CSD Equipment $393,000 384,280 579,816
2-FCZ781 (JMC)
CSL Equipment $514,000 302,795 234,783
2-FCZ782 (JLH)
HPP Equipment $484,000 127,625 0
2-FCZ783 (EAF)
---------- ---------- ----------
$1,615,000 $ 950,000 $ 814,599 $3,379,599
The 6/83 column is what we worked out previously. The 1/84 column funds
all 4 subaccounts through May 1984, in accord with the May 2, 1983
budget revision submitted to DSSW. The last column represents the funds
we expect to receive around 6/84 for contract year 2 (VAX 11/780, "large
time-shared system", and CSD-CF personnel). We are actually overfunded
by $2,700 through May 1984 -- I allocated those funds to CSD-CF.
Let me know if any of this is unclear. Tom R.

To: bosack@SU-SCORE, JMC@SU-AI
The terminal nearest the door in 362MJX (my office mates)
is very hard to use due to barely legible display.
I asked Don Coates if he could fix it and he said he could
but `they' wouldn't let him order the necessary parts.
Said `I should speak to his bosses', but when I asked
who precisely, he just said that was for me to find out.
I don't know what is going on, but it seems to me that
one should be able to get a terminal with a legible display.
Any suggestions?

$3,767.00 special coach fare. We deducted the price of a business class
ticket ($2,578.00) for you. That leaves you owing us $1,189.00 for your
wife. Please make the check payable to Carnegie-Mellon University and
send it to me: Beverly Howell, Robotics Institute, CMU, Pittsburgh 15213.
If there are any questions please get in touch with me or with Raj.

In response to a message to John Machado, asking whether the current contract
was going to be extended -- for sure -- past 1/31, he called me. The latest
word is that it is indeed going to be extended for some period of time, and
a modification will be issued for a fairly "substantial" funding increment.
I am sorry to be vague, but he would not give me any details. So, we just
have to take his telephoned word, and wait for the paperwork.
I think a substantial funding increment means further delays in the umbrella
contract, but I will let you know as soon as I have any additional informa-
tion.

hi john.i met steve russell friday.he really got grey hairs.and he still
is a member of the mit tech railroad club.he remembered not veryy much
but convinced me that he started the first interpreter - an apply-
function only - in december 58.i already di know that this should have
existed.the program really seems to be lost.(the first version of your
"recursive functions..." pa\zper.)the he remembered that this apply was
completed in late january.he claimed that it was'nt the substitution apply
which is des cribed in memo8 of febraur 58.(59 of course)
the apply-eval of may(did i tell you that joel moses has saved a program
listin ng?)59 was according to him the second version(he was not quite
correct to date it).he remembered that garbage collectionm was proposed
very early after considerable study of alternatives.he was not sure if it
was new then.
new for me was that you already hadeady had ordered to do work at
Dartmouth because he was student in mathematics there (he didn't remember
that he did anything at all that time for you but learned to program the
704.)you see-that's not very much.the paper which i was searching for he
was pretty shure to have never written it.
the basic question is now,where may be a record of this first apply function?
that's all.i thank you very much for the kind treatment.bye.
∂16-Jan-84 0945 DFH SAIL Accts./CS258
I spoke with Stuart about this. He needs you to
send him a message stating exactly what facilities
that are unique to SAIL that the CS258 students need
to use (he is Reges@score). Then he will notify Lynn
and we will arrange to set up the accounts. He would
also like your estimate of the computer charges for
the class. Even those students who already have SAIL
accounts will have to get another one just for CS258
use, as there is no practical way of breaking down
the charges on their existing accounts. There is
money available, and there should be no problem with
getting the accounts.
The SAIL accounts for CS258 are needed because of the character
set used for the EKL interactive theorem prover and the integration
of EKL with the editor. The use of EKL on LOTS last quarter was
rather unsatisfactory. The students will also use the Boyer-Moore
theorem prover (Maclisp version) which is being supported on SAIL
only at present. There are about 12 students and I'll guess $150
apiece.

John has convinced me that his 258 class will require resources unique to
SAIL. Therefore, it is appropriate to set up special accounts for the students
in that class and charge their use to 1-FCZ050. John believe the students will
use something like $150 for the course. Naturally, we can't limit that on SAIL,
but if you see anyone who is way out of line you might warn John and/or myself.
Dianna will provide you with a list of names of students in the class. I
suggest doing the normal thing, setting up accounts names like CS258-FOOBAR,
where FOOBAR is the person's last name.
John, please let your students know that they should use these special accounts
for their classwork even if they have SAIL accounts already.

-Such a system for a simple database as described by John McCarthy is used
on the STAR-VAX and uses the VMS SEARCH command to locate information. A
couple of Command Procedures have been written to enter and retrieve information
from the database and it is possible to have several files, eg: addresses,
phone messages, program notes, etc. This system is used by several members of
the Space Plasma Physics group and it has been found to be quite handy.

The book still provides a lot insight into how the system
"works", but it in no way offers the kind of information one
wants in a user's manual. The old SRI manual is very
inaccurate now. The best that we can offer at the moment is
the file CODE.DOC, of which Carolyn has a copy. It's only
merit is its brevity. Any statement from you about what
kind of information you would like the students to have
would undoubtedly influence what we write.

From: Robert Elton Maas <REM @ MIT-MC>
Subject: output-directed debugging/verification of software
To: JMC @ SU-AI
I'm in the process of developing a system for aiding debugging of
software by tracing errors in output back to their causes. (Sussman
apparently did something similar in the 70's although I didn't find
out about it until I had independently thought of it and for years
been advocating the approach to people who ask what is next for
programmer environments after windows&mice.)
In the process of describing my idea, I often paraphrase something you
once said to the effect that the only reall important thing about a
program is the output it produces, which is right or wrong
independently of how "pretty" the program is etc. Could you supply me
with a reference and exact quote so I can do you justice in my
documentation/report?
I can't think of a reference, and I don't suppose I said precisely that.
In my theoretical work I emphasized what is sometimes called extensional
properties of programs, i.e. the input-output relation.
∂16-Jan-84 1939 JK
One way to handle programs and partial functions:
Describe programs as input-output relations.
Have the following general axiom:
For any relation R there is a function selector(R) such that
for any x:
∃y.R(x,y) →→ R(x,(selector(R))(x)))

NATIONAL CONFERENCE ON ARTIFICIAL INTELLIGENCE
AAAI-84 is the fourth national conference sponsored by the American
Association for Artificial Intelligence. The purpose of the National
Conference is to promote research in the field of Artificial
Intelligence by bringing together individuals from government,
commerce and academia and by providing a published record of the
National Conference as proceedings.
The three main parts of AAAI-84 are the Technical Program, the
Tutorial Program and the Research & Development (R&D) Exhibit Program.
Because this year's facilities are smaller, registration for the
technical and tutorial programs will be limited. Please register
early.
THE TECHNICAL PROGRAM
August 7 to 10, 1984
The Technical Program is the main annual forum for researchers to send
previously unreported results to an extensive technical audience. The
program will feature substantial, original research in subfields of
Artificial Intelligence (representative topics are noted below). All
papers will be refereed by a Program Committee of prominent
researchers in the field, and acceptance for presentation at the
conference will be based on the originality and significance of the
reported research as well as the quality of the exposition of the
ideas. In the past, AAAI conference proceedings have provided a
high-quality record of current research in Artificial Intelligence.
In order to encourage outstanding technical contributors, a Publisher's
Prize of $1,000, donated by the MIT Press, will be awarded to the best
paper. Submitted papers that present significant research accomplishments,
and are considered to be paragons of clear writing, will be nominated for
the Prize. The Program Committee will then select the best paper from
the publication versions of those nominated. The prize-winning paper,
with other nominees considered of comparable quality, will be featured at
a special session of the conference.
AAAI-84 encourages theoretical contributions in any of the topics
noted below. The Program Committee will also consider papers that
clearly demonstrate the power of accomplished techniques. Thoughtful
and convincing critiques will be considered appropriate if it fosters
good scientific research in AI.
!
CONFERENCE TOPICS
AI and Education (including Intelligent CAI)
AI Architectures and Languages
Automated Reasoning (including automatic programming,
automatic theorem-proving, commonsense reasoning, planning,
problem solving, qualitative reasoning, search)
Cognitive Modelling
Expert Systems
Knowledge Representation
Learning
Methodology (including technology transfer)
Natural Language (including generation, understanding)
Perception (including speech, vision)
Philosophical and Scientific Foundations
Robotics
We plan to vary the structure of this year's technical conference.
With this new format we hope to avoid typical conflicts among
competing sessions and allow researchers to interact more intensively
in their areas of specialization.
Tuesday, August 7, and Wednesday, August 8 will feature accepted papers
in the technical subfields of AI. We plan to have a small number of
parallel sessions (nominally 3) during these two days, with very little
overlap in interest among the parallel sessions. These specialized sessions
may also feature panel discussions and invited speakers, where the topic
of discussion is fairly narrow.
On Thursday, August 9, and Friday, August 10, attention to the topics
of more general interest to the AI community will be
presented. Those days will feature plenary sessions which will include
the President's Address, presentations of papers nominated for the
Publisher's Prize and accepted papers of general interest, and invited
talks and discussions on broad topics ( i.e. logic programming,
computer learning).
[ sections on tutorial descriptions ]
AAAI-84 RESEARCH & DEVELOPMENT (R&D) EXHIBIT PROGRAM
August 6 to 10, 1984
An important service provided by the AAAI to the conference attendees
is the week-long R&D Exhibit Program. In a dedicated exhibit area in
the Performing Arts Center, hardware and software manufacturers will
display and demonstrate products and/or services relevant to the AI
community. As in the past, university and industrial laboratories
have been invited to participate in the R&D Exhibit Program. Leading
publishers will take the opportunity to display a variety of titles in
Artificial Intelligence, computer science, cognitive science,
linguistics, and other related disciplines. Previous participants in
AAAI exhibit programs have included:
Machine Intelligence Corporation, The LISP Company,
Addison-Wesley Company, SRI International, Inference
Corporation, Stanford University, MIT Press,
Digital Equipment Corporation, Symbolics, Lisp Machines,
Elsevier-North Holland, William Kaufmann Inc., IntelliGenetics

TUTORIAL NO. 1: AN OVERVIEW OF ARTIFICIAL INTELLIGENCE
Monday, August 6, 1984
9:00 a.m. to 1:00 p.m.
PREFACE
The field of AI is exploding, along with the demand for people who can
practice and manage it. The reason is clear: AI technology is needed
to cut the cost of writing and maintaining programs, to build smart
robots, to automate offices, to create expert systems for engineering,
medical, artistic, and business applications, to diagnose and even
design hardware and in general to cope with complexity.
CONTENT
While the literature on AI is vast and growing, it is still possible
to understand the fundamentals in a few hours. Attendees at this
tutorial will learn how AI programs work, and why, and will develop a
feel for what can be done easily, what may be done with effort and
what cannot be done without breakthroughs in research.
SPECIFICS
This tutorial will examine:
(1) Introduction: What is Artificial Intelligence?
Examples of AI programs. A brief history of AI.
(2) Problem Solving by Search: How are various problems
cast as searches? What types of information can be brought to
bear on a problem, when the search for a solution threatens to be
interminable? How are these various types of
knowledge represented in, and used by, computer programs?
(3) Understanding: What are the problems that arise (and
solutions that have been found) in getting programs to
understand speech, visual images, and prose (see related tutorial 3)
(4) Learning and teaching: Getting programs to automatically acquire
new knowledge, by being told, by observing, by analogy,
and by proposing and carrying out experiments.
Getting programs to teach their knowledge to humans (see
related tutorial 2).
(5) AI Programming: Special purpose languages (such as LISP and
Prolog) and machines suited to the development of AI programs
(see related tutorials 6 and 7).
(6) Dealing with difficulties (such as conflicting goals and uncertain
knowledge) and opportunities (such as parallel processing).
Achieving expert-level performance (see related tutorials 4 and 5).
(7) Synthesis: Speculations on the nature of
intelligence; why AI methods "work"; a timetable of future
achievements and failures of AI, with specific attention to the
recent trend toward industrializing AI.
INTENDED AUDIENCE
This tutorial is intended for engineers, scientists, and technical
managers interested in learning about AI. It will be particularly
useful for those who may become involved in an AI effort at
their own company, because the lecturers will detail the
limitations and common problems with transferring AI technology
to industry. It presumes no previous experience with
Artificial Intelligence, and serves as a good foundation for
most of the following tutorials.
LECTURERS
Dr. Douglas B. Lenat received his Ph.D. from Stanford in 1976. His thesis,
AM, was an application of the expert systems paradigm to the open-ended
task of theory formation in mathematics. Lenat received the biannual
Computers & Thought Award by the International Joint Committee on
Artificial Intelligence, for this work, in 1977. He is now an assistant
professor of computer science at Stanford University, and has built
expert systems which learn by discovery in such fields as ship design,
programming, and VLSI design. Lenat has given tutorials on expert
systems for Teknowledge, Inc., WICS, at the 1981 NCC, and also at the
first AAAI conference (1980), and again at NCC in 1981. In 1982, he
was awarded the Publisher's Prize for the best paper at AAAI-82 National
Conference, for his paper presenting a synthesis of ideas on the nature
of heuristic reasoning. Lenat is on the editorial board of the Journal
of Automated Reasoning, and of the Pitman Research Notes in AI. In
1983, he was invited to give the keynote address on Machine Learning at
IJCAI, and one of the two invited talks at AAAI. Besides his Stanford
affiliation, he currently consults for Thinking Machines Corporation and
Teknowledge. Lenat has authored chapters in several books, including
the recently-issued@i Building Expert Systems, of which he is co-editor.
Dr. Marvin Minsky is MIT's Donner Professor of Science since 1974.
Between 1968 and 1973, he was the director of MIT's Artificial
Intelligence Laboratory, which he co-founded with John McCarthy in
1958. Dr. Minsky received his Ph.d in Mathematics from Princeton in
1954, after receiving his A.B in Mathematics from Harvard. In 1956,
Drs. Minsky and McCarthy and others participated in the Dartmouth
Summer Research Project on Artificial Intelligence - one of the first
opportunities to discuss the possibility of simulating learning and
other features of intelligence with the use of machines.
In 1951, Dr. Minsky and Dean Edmonds built one of the first electronic
learning machines. Later in 1956, he became interested in using computers
to prove euclidean theorems. In 1957, he became a staff member at MIT's
Lincoln Lab where he worked on pattern recognition. In 1958, he
moved into MIT's Mathematics Department and started the AI group.
In 1963, working with Seymour Papert, they initiated research programs
in human perception, child psychology, experimental robots and the
theory of computation. In 1969, they wrote @i Perceptrons as an attempt
to reveal the inadequacies of the Perceptron project.
Under Minsky's guidance, early research programs, such as James Slagle's
SAINT program and Daniel Bobrow's STUDENT program, emerged. In the mid-
1960s, Minsky and Papert developed the "Society of the Minds" theory
which suggests intelligence emerges from the interaction of many small
systems operating within an evolving administrative structure.
Recently, Minsky has studied the use of robots in space and on earth to
the development of the human mind and its ability to deal with
paradoxes.
Dr. Minsky is a former President of the American Association for
Artificial Intelligence and recently the co-founder of Thinking Machines
Corp.

TUTORIAL NO. 2: APPLICATIONS OF AI TO TRAINING AND EDUCATION
Monday, August 6
2:00 to 6:00 p.m.
PREFACE:
Advances in hardware, expert systems, and machine learning, coupled
with recent theories of cognition, make possible new kinds of learning
and training environments -- environments that use intelligent,
computer-based coaches to maximize the benefits of learning-by-doing.
These new environments incorporate explicit models of subject matter
expertise, theories of how material is learned or mislearned,
notions of how procedural skills are mastered with "understanding"
rather than just rotely performed. Recent research on mental models
suggests that "cognitive fidelity" in training simulators is as
important as physical fidelity, thus opening up the possibility for
teaching generic understanding of complex systems. The examples
provided by these environments change our conceptualization of what an
intelligent job performance aid can do, as well as setting strong
requirements for the design of expert systems.
CONTENT:
This tutorial will survey the state of the art in the use of AI for
instruction. Special emphasis will be placed on detailed examples of
how to build computer-based coaches, how to build diagnostic systems
capable of inducing a user's understanding and misunderstandings of the
domain and how to tailor explanation to the user rather than the
machine. Methods for exploiting the new generation of personal AI
machines for tutoring will be discussed.
SPECIFICS
The tutorial will examine:
(1) Knowledge representation techniques appropriate for education.
(2) Construction and use of student models.
(3) The nature of student misconceptions.
(4) Qualitative and analogical reasoning.
(5) The interaction between explanation and the structure of knowledge in
expert systems.
(6) Using computer-based coaches with games to increase educational
effectiveness.
(7) Using intelligent tutoring techniques to provide novel man-machine
interfaces.
INTENDED AUDIENCE
This tutorial is intended for professionals wanting to understand the
impact AI will have on training and education, those wanting to
construct a new generation of man-machine interfaces, and those
interested in building self-explaining, intelligent systems.!

TUTORIAL NO. 3: NATURAL LANGUAGE PROCESSING
Monday, August 6th, 1984
2:00 - 6:00 p.m.
PREFACE
The field of natural language processing is producing dramatic solutions
to a wide range of user-interface problems in commercial computing
applications. Vast amounts of information stored in traditional databases
can now be accessed by users who have no background training in computer
programming or formal query languages. Natural language interfaces can also
be designed for a variety of software applications that were previously
available to programmers. Yet the state of the art is still constrained
by a number of very difficult problems that remain to be solved. In this
tutorial, we will discuss what can and can't be done in an effort to
acquaint senior managers and research coordinators with the current
technology in natural language processing systems.
CONTENT
This tutorial will survey the state of the art in computer-based language
processing. It will review current and potential applications of
natural language research, introduce theoretical issues and processing
techniques, present a survey of commercial systems and present recommendations
on the requirements for a successful research environment.
SPECIFICS
This tutorial will examine:
(1) An overview of existing and potential applications: machine
translation aids, database interfacing, interviewing and advisory
systems, text analyzers, intelligent computer-aided instruction.
(2) The theoretical problems: syntax, semantics, inference,
domain-dependence vs. domain-independence.
(3) Popular processing techniques: syntactic parse trees, lexical case
frames, predicate calculus, conceptual decomposition, predictive
knowledge structures, context-driven analysis.
(4) A survey of commercially available systems: capabilities and
limitations, resource requirements, maintenance and extensibility.
(5) Establishing a research environment: computing resource requirements,
locating personnel, realistic time frames.
(A comprehensive list of references will be organized by tutorial
topics and distributed to all participants)
INTENDED AUDIENCE
This is an introductory tutorial suitable for (1) technical managers
who need to evaluate the capabilities and costs of commercial natural
language processing technology, and (2) senior managers who are new to
the field and want to establish in-house projects in the area of
natural language processing. No previous background in linguistics is
assumed, although some familiarity with computers is desirable.
LECTURER

TUTORIAL NO. 4: BUILDING EXPERT SYSTEMS: PART 1 - FUNDAMENTALS
Tuesday, August 7, 1984
9:00 a.m. to 1:00 p.m.
PREFACE
A major goal of Artificial Intelligence has been to develop
computer systems to perform intellectual tasks which are currently
performed by highly skilled experts. In the past few years, this goal
has come dramatically closer, and in limited cases has been achieved.
Understanding the basic principles of how such expert systems work and
how they may be applied is becoming increasingly important for
forecasting and influencing the future shape of technology in
industry, education, science, government and commerce.
CONTENT
The tutorial will review the state of the art and future
prospects for building computer systems which perform expert tasks
automatically, and systems which are used interactively by experts to
amplify their productivity. The emphasis will be on the fundamental
issues and technical considerations in building expert systems, across
a wide range of domains.
Part 1 may be taken as a self-contained introduction to the topic, or as
a preparation for Part 2.
SPECIFICS
The tutorial covers the basic steps in developing an
expert system:
(1) Problem selection and bounding: What are the features of an
intellectual task which make it more or less amenable to existing
expert systems technology?
(2) System architecture selection: The programming techniques used in
constructing expert systems differ markedly from those of conventional
numerical and data processing. We cover the various formalisms
currently available for encoding knowledge, such as semantic networks,
inference rules, production rules, frames, plans and scripts. Given
a programming formalism, how should one choose or design facilities
for reasoning about knowledge in that formalism?
(3) Knowledge acquisition: Should the knowledge be acquired by
debriefing experts, incrementally through experts' critiques of the
system, automatically by machine learning, or through some combination
of these methods? What are the techniques for each of these knowledge
acquisition paradigms? What tools can aid the design, construction
and modification of large knowledge bases?
(4) System evaluation and amelioration: How can expert systems be
compared, or have their performance judged on an absolute scale? The
reason for this is not merely evaluation for its own sake, but an
integral part of the process of building expert systems. Typically
the developers repeatedly return to the first or third step in this
list; why, when, and how is this carried out?
INTENDED AUDIENCE
This is an introductory tutorial suitable for those who desire an
understanding of how AI techniques can be used to solve difficult
real-world problems. Those who wish to evaluate the potential for
using expert systems in their own area of work, or who intend to
develop or manage such efforts, should also take Part 2.
LECTURERS
Dr. John McDermott is a Senior Research Computer Scientist and the
Associate Head of the Computer Science Department at Carnegie-Mellon
University. Before coming to Carnegie-Mellon in 1974, he was an
Assistant Professor of Philosophy at Eisenhower College (1969-1974).
He received a Ph.D. in philosophy from the University of Notre Dame in
1969 after receiving a B.A. and M.A. from St. Louis University.
His research interests are in the area of artificial intelligence,
particularly in the application of AI techniques to industrial
problems and in developing computer programs that simulate human
cognitive processes. He is the author of over 40 papers and
technical reports on these subjects.
Since 1978 the primary focus of his efforts has been in addressing
the problems involved in developing "expert systems" -- computer
programs that contain the wealth of domain-specific knowledge that
human experts require in order to function effectively. In 1980 he
completed work on R1, a program used by Digital Equipment
Corporation's manufacturing organization to configure computer
systems. Since that time, he and his colleagues have developed a number
of expert systems in a variety of domains. These systems include a computer
system sizing assistant, manufacturing management assistants, a drilling
fluid consultant, a threat assessment system and a VLSI design assistant.
The other lecturer is Dr. Douglas Lenat (see biographical sketch
earlier.)!
TUTORIAL NO. 5: BUILDING EXPERT SYSTEMS - PART 2: PRAGMATICS
Tuesday, August 7, 1984
2:00 p.m. to 6:00 p.m.
PREFACE
Increased productivity demands and a shortage of human experts have
caused the pioneering development of expert systems in the areas of
manufacturing, engineering,medicine and technical training. This
tutorial will also cover real-world issues most critical to the
successful development of expert systems; e.g. the requirements and
current availabilities of hardware, software and personnel.
CONTENT
The tutorial builds on Part 1 by presenting several in-depth case
studies of expert systems in different domains. Case studies will
be drawn from both existing and current research. This tutorial
will emphasize what has been learned about the domains of manufacturing,
engineering, medicine and technical training from an AI perspective,
and an examination of the techniques developed in each area. Additional
general topics, such as hardware and software requirements, personnel
needs and timetables will also be discussed.
SPECIFICS

TUTORIAL NO. 6: A TUTORIAL ON LISP
Tuesday, August 7
9:00 a.m. to 1:00 p.m.
PREFACE
LISP, created more than 25 years ago, is one of the earliest
programming languages. Although it has never been standardized, and for
most of its history was unsupported by any computer manufacturer, today
it enjoys increasingly widespread use and active development. The reason is
that LISP is the working language of the Artificial Intelligence community.
Through the work of major AI research centers, LISP evolved from a simple
list processor based on Church's lambda calculus into what is now widely
acknowledged to be the most advanced programming environment in existence.
Most research in expert systems, natural language understanding, cognitive
simulation, and real-world knowledge representation, and application work in
robotics and machine perception utilizes LISP, or languages based on
LISP. Familiarity with LISP is a prerequisite to any in-depth understanding
of AI and its special programming techniques.
CONTENT
The tutorial will explore the features that distinguish LISP
from conventional programming languages, assess its importance in AI
research today and in the future and teach some elementary LISP
programming.
SPECIFICS
The tutorial will examine:
(1) A brief history of LISP, including a comparison of the major
dialects in use.
(2) Why LISP is different: the crucial importance of symbols and
lists as primitive datatypes.
(3) The LISP interpreter: programs as data; the advantages of
interpretive execution; how automatic storage allocation and
garbage collection are implemented and why they are necessary.
(4) How LISP facilitates recursive, applicative, rule-based,
and object-oriented approaches to programming.
(5) The LISP programming environment: exploratory programming style;
LISP-based editors and debuggers; windows, flavors, and other
advanced features.
(6) Elementary LISP programming.
SPACE IS LIMITED AT THIS TUTORIAL.
INTENDED AUDIENCE
The tutorial is intended for technical professionals planning to
become involved in artificial intelligence projects, and for managers who
will oversee the development of AI applications. It is also appropriate for
students of AI or cognitive science who wish to pursue an in-depth study of
those fields. It is assumed that attendees have experience with at least
one conventional programming language.
LECTURER
Dr. David Touretzky is a research associate in computer science at
Carnegie-Mellon University. He received a Ph.D. from Carnegie-Mellon in
1984 in Computer Science. Dr. Touretzky is the author of @i[LISP: A Gentle
Introduction to Symbolic Computation,] and @i[A Summary of MacLISP
Functions and Flags]. He is the creator of Carnegie-Mellon's novel
LISP-based introductory programming course, where LISP's interactive nature
and advanced datatypes and built-in functions aid humanities students in
their first exposure to computing. Dr. Touretzky's research for the last
five years has been on the semantics of NETL, a massively parallel
knowledge representation system, and on the mathematics of inheritance
hierarchies. He is presently a member of CMU's Boltzmann Machine research
group, where he is investigating the application of stochastic neural
network architectures to symbolic reasoning.

TUTORIAL NO. 7 : ARTIFICIAL INTELLIGENCE PROGRAMMING TECHNIQUES
Tuesday, August 7, 1984
2:00 to 1:00 p.m.
PREFACE
Most AI workers still find LISP to be the most convenient tool for
expressing their algorithms. LISP, however, is a fairly
general purpose language and thus most AI applications require
programming techniques which are above the level of basic LISP, but
below that of the particular application. Often there are existing
packages to help, but these rarely do exactly what you want. Thus
the AI programmer must know how to build the tools of his trade.
CONTENTS
This tutorial will look at many of the basic techniques which underlie
programs in many AI application areas: expert systems, natural
language comprehension, problem solving, and so forth. These tools
solve basic programming problems which crop up all of the time:
pattern matching, efficient data retrieval under various
circumstances, and scheduling activities, to name but a few. This
tutorial will explain the basic ideas, and then go into the actual
code which implements the ideas.
SPECIFICS
This tutorial will examine the following questions:
(1) Why AI programming packages almost never do what you
want.
(2) What tools are needed for building expert systems?
(3) Basic pattern matching: unification and its extensions.
(4) Creating a data base: property lists, associative net-
works, and discrimination nets.
(5) Inference techniques: backward and forward chaining.
(6) What to do next: agendas and backtracking.
(7) Explaining what you know: data dependencies.
INTENDED AUDIENCE
This tutorial is intended for people who have had some experience with
AI and LISP and who want to be able to write sophisticated AI programs
in LISP. It is not necessary to be a good Lisp programmer to
understand the material, but one should have a "reading acquaintance"
with the language.
SPACE IS LIMITED FOR THIS TUTORIAL.

This year, the AAAI offers housing on the University of Texas campus
and at local hotels. Housing reservations will be processed by either
the University of Texas's housing staff for dormitory rooms or by the
Austin Chamber of Commerce's Central Housing Bureau for local hotel
rooms. Two separate housing forms are located in the back of the
brochure.
JESTER CENTER, University of Texas campus
The University of Texas's Jester Center will be the principal location
for housing during AAAI-84 National Conference. The Jester Center is a
high-rise residence hall and academic complex which accommodates a
maximum of 3,000 persons in double rooms. A total of 1,000
spaces have been reserved for the AAAI-84 Conference.
Summer conference accommodations are offered to University-sponsored
groups as a package rate including both meals and a room. The type of
room is designated as either connecting or community bath space.
Rooms with connecting bath space share these facilities with the
adjacent room only and receive daily housekeeping service, which
includes making the bed. Community bath facilities are shared by
approximately twelve rooms. Rooms served by community bath receive
housekeeping service every fourth day. In addition to twin beds, each
room has two desks with chairs, two chests of drawers, ample closet
space, and a lavatory. Bed and bath linens are normally provided; bath
linens are exchanged daily; bed linens are exchanged after the third
day of the conference.
Meals will be served cafeteria-style in an area of the Jester Center
Dining Room. Usual meal hours are 7:00 a.m. to 8:15 a.m. for
breakfast, 12:30 a.m. to 2:00 p.m. for lunch, and 5:00 p.m. to 6:15
p.m. for dinner. Lunch and dinner will feature a choice of two
entrees and two vegetables, salad bar with green salad and choice of
dressing and daily selection of vegetable, gelatin, and fruit salad,
assorted breads, beverages, and desserts. The first meal provided
will be dinner on August 5.
Reservations will be made directly with the Division of Housing and
Food Service (send in the attached dorm housing form) and confirmed by
mail if received two weeks in advance of the conference.
EVERY EFFORT WILL BE MADE BY THE DIVISION OF HOUSING AND FOOD
TO ACCOMMODATE RESERVATIONS RECEIVED AFTER JULY 23, 1984, BUT NO
SPACE WILL BE HELD FOR THE GROUP BEYOND THAT DATE.
Full payment of the package rate by cash, money order, check or
traveler's check will be expected at the time of the check-in. NO
CREDIT CARDS, FOREIGN CURRENCY AND FOREIGN CHECKS WILL BE ACCEPTED.
There are no refunds for late arrival, early departure or missed
meals. Check-out time is 2:00 p.m.
**************************************************************************
Jester Center is located at the corner of Speedway and Twenty-First Streets
on the University of Texas at Austin Campus. From Interstate highway 35, take
Martin Luther King Blvd west to Speedway. Automobile parking is available
as space permits in "C" lots 67 (first two rows only), south of Jester Center,
and in Lots 69 and 70, south and east of Memorial Stadium. Temporary "C"
permits, allowing conference attendees to park only in "C" parking areas,
are issued with the room confirmation or at the time of check-in at
Jester Center. Car license plate number is required prior to issuance of
a permit. "C" permits allow parking only in lots designated for "C" permit
holders, 7:30 a.m. to 5:00 p.m., Monday - Friday. The permits do not
allow attendees to drive through UT police manned control stations to
the inner campus until after 5:00 p.m. After 5:00 p.m. and on Saturday and
Sunday, attendees may park in any parking area not otherwise prohibited
by a posted sign.

John, can you tell me the name of the course which Doug Lenat taught
last year, and which you referred to as the "learning course" at yesterday's
meeting. I thought I could look it up later, but I'm not having much success.
He taught CS 229, Topics in Artificial Intelligence, and CS 224, Survey
of Research Topics in AI. I assume the learning course was one of these?
Thanks,

The latest chapter is that Navelex will fund the current contract by about
$700,000 to last through 9/30/84. I have no official modification paperwork,
but it is rather certain that this will happen. I have no idea at the moment
just for what project(s) the funds are being allocated. Will have to wait and
see what the modification says.
In the meantime, I plan to guarantee expenditures on the McCarthy and
Wiederhold accounts, so that CSD-CF charges and salaries can be paid. If
further checking reveals that other accounts need guarantees, I will take care
of it. I don't plan to guarantee equipment expenditures.
I will welcome any comments, if you care to make any.

Now that I am in charge of the foundations area, I think I should butt out
of the computation area planning. So you should each think about what can
and should be done to make the area exciting. After Betsy and Brian get
clear about the budget for that area (which is pretty flush compared to
other areas), you should have a meeting and decide who you want to go after.
For academic types, this is the time of year to make offers.

While a check for bigrams is certainly simpler than one for trigrams,
it turns out that for the set of words in the Unix dictionary, bigram space
is 82% populated while trigram space is only 30% populated. If the
algorithm were based on bigrams, it would be much more difficult to
pick a psuedo-random letter string that would pass the test because a much
higher percentage of random strings would be rejected by the algorithm.
The present algorithm rejects about 12% of random eight character strings
(based on experiment). Checking bigrams would reject a much higher percentage,
so trigrams seem to be the unit of choice. Groups of four characters
(quadgrams?) would require a table 27 times larger, which would be
inconvenient. A formal analysis of this problem might be interesting.
I am much more concerned about the human engineering of the
approach, which is why I made the program available on SCORE. I have
received a large number of comments, some of which are useful. To date
no one has complained that they could not find any word that the
algorithm would accept, nor has anyone found the algorithm not restrictive
enough. This indicates that I am on the right track. Bear in mind that
the primary alternative to a restriction of this kind is machine-generated
passwords, which certainly would be more painful for users.
John Nagle
If bigrams are used, one would want to exclude only bigrams that
have a significant frequency. Doing this would probably give an acceptable
number of passwords of acceptable unobviousness. At least my experiments
with your program suggested this. Actually I'm not sure one wants to exclude
all words in the dictionary if one wants to be sure that people memorize
the passwords rather than write them down.

;I think I have found a very elegant way of doing all inductive definitions:
;it turns out that by doing primitive recursion on HIGHER TYPES
;you can solve the problems we discussed before
;here is for example flatten:
(get-proofs lispax prf prf jk)
(proof test)
(decl (arb arb1 arb2) (type: |?arbitrary|))
(decl bigfun (type: |@arb⊗@arb→@arb|))
(decl defined_fun (type: |ground→@arb|))
(decl (defined_fun atom_fun fun1 fun2) (type: |ground→@arb|))
;now state the (primitive recursive schema) for definition on ALL
;higher type functionals:
;note the use of the variable type in declarations;
;in this way we can specialize to ANY type.
;thus this axiom is really schema. It is the most general
;induction schema that I can formulate:
;the one with parameters follows trivially.
(axiom
|∀bigfun atom_fun.∃defined_fun.∀x y.(atom x ⊃ defined_fun(x)=atom_fun(x))∧
(defined_fun(x.y)=
bigfun(defined_fun(x),defined_fun(y)))|)
(label high_order_definition)
:now can define flatfun(x)=λy.flat(x,y)
;has to done explicitly since the unifier does not coerce
;variable types
(define flatfun |∀x y.(atom(x)⊃flatfun(x)=(λY.X.Y))∧
(flatfun(X.Y)=(λZ.(flatfun(X))((flatfun(Y))(Z))))|
(use high_order_definition
ue: ((atom_fun.|λx.λy.x.y|)

One measure I've never seen anyone apply is to install a time-lock
mechanism in the system which the user could set to lock out all
logins to their account for specific time periods. Just as banks
use time-locks on vaults which prevent them from being opened over
night, users could specify their account shouldn't be accessible for
n-hours or n-days, or during specified hours of the day.

Ah, but think of the frustration a time-lock would cause the vandals
if the account didn't APPEAR to be locked out... I.e. They could even
guess the correct password and it wouldn't work.

In your Quarterly Message, you remark:
"The ratio of basic/applied is less in AI than in the older sciences
and than in computer science generally."
Have statistics been published to support this?
I'd be interested in seeing them.
How about the ratio of older/younger researchers?
I suspect that that ratio will distinguish AI as well,
but that in a while AI will assume the familiar distribution.

I have a few new proof files in [prf,jk]:
Subst.lsp[prf,jk] does the definition and properties of subst
(the unification algorithm does require the pars arguments to appear last:
this is the reason for reversing arguments to subst)
Flat.lsp[prf,jk] does the definition and properties of flatten
Mapcar.lsp[prf,jk] does the definition and properties of mapcar on multiple lists
Distin.lsp[prf,jk] does the predicate distinct(a,b,c,..)=a≠b∧a≠c∧b≠c∧... for
arbitrary number of arguments.
Der uses now high order unification.
A bug or a feature?
Unrestricted Skolemisation is equivalent to Axiom of Choice.

I think GNU will meet most of your goals for an operating system,
except for virtual machine facility and support of arbitrary character sets
(the latter being something that depends on special hardware and therefore
not in my department). I will provide a version of TEX, but not SCRIBE
until I get around to writing a clone of SCRIBE.
-------
Part of support of arbitrary character sets depends on hardware, but
part of it also depends on editors, etc. For example, an editor that
supports arbitrary character sets must allow characters to have
variable length internal representations. Also, although I have not
used UNIX, what I have read about its defects on BBOARD makes me
somewhat skeptical of anything based on its external characteristics.

From: jbn@FORD-WDL1.ARPA
Subject: Obviousness of words
To: JMC@SU-AI.ARPA
Cc: jbn
The primary reason for excluding all words in the dictionary is that
systems with encrypted but not otherwise protected passwords can be attacked
by obtaining the encrypted password file, running all available dictionaries
through the encryption algorithm, and looking for matches. See "Notes on
the Security of UNIX" (supplied as part of full UNIX documentation sets)
by, I think, Richey.
It is a difficult problem to detect guessable passwords without disallowing
too many reasonable passwords. My algorithm disallows about 12% of all 8-letter
sequences, and this 12% contains most of the English language. A more
elaborate algorithm might bring the 12% figure down, but 12% is reasonably
acceptable; a user has an 88% chance of coming up with an acceptable string
on the first try and about a 98.5% chance in two tries, provided that the
user is coming up with reasonably random strings. This seems to be a usable
rejection level.
I appreciate your thoughts on the subject; at present my own feeling
is that the handling of alphabetic sequences is acceptable but the handling
of nonalphabetic characters is not; a definition of non-obvious sequences
containing nonalphabetics depends heavily on the use of such sequences in
the user's culture; I presently disallow sequences formed entirely of
nonalphabetics having no strong ideas in this area. It is known that
numeric sequences must be disallowed, to prevent the use of telephone numbers,
license numbers (Richey, ibid.) and other personally significant numbers.
Beyond this, the local system conventions are significant.
As it happens, I use obsolete telephone numbers. My present password
is the number of a 1952 girl friend, or at least the way I remember
that number. In my judgment this is secure enough. A rigid rule
enforced by the installation preventing the use of telephone numbers
may reduce security by encouraging the user to keep the password in
a file somewhere. I didn't know about the problem of running the
dictionary against the file of encrypted passwords, so I'll have to
think more.

Dear Professor McCarthy,
Re your circumscription article in the AI Journal 1980.
My name is Charles Petrie and I am a graduate student at UT interested in
non-monotonic logic with a question about circumscription. In example
seven in the above article, in order to circumscribe the predicate
"prevents", a sentence must be constructed of all of the propositions that
might imply satisfaction of the predicate. It seemed to me that in this
example, to circumscribe the predicate was to assert that it was not
provable that there was a "z" such that "prevents (z, ..." which would not
be decidable. However, you noted that the goodness of the constructed
sentence depended on the program "finding all of the relevant statements"
which implies that the issue is only a practical matter.
In general, the seventh example suggested to me that circumscription was
equivalent to saying that an assertion could be assumed if it were
consistent to do so. I have talked with several people, but have found no
one who will admit to being sufficiently competent to even try to
"de-confuse" me on all of this. So I thought I would go to the source.
Any references or comments from you would be sincerely appreciated. Thank
you for your time and thought.
I can be reached via ARPANET at Dr. Simmons address. Or, I receive mail at
610 Rockpark Dr., Austin, TX 78746.
Sincerely,
Charles Petrie

As previously announced, the second seminar on reasoning about
knowledge will take place on Friday, January 27, at 2 P.M., at IBM.
The speaker will be John McCarthy of Stanford. Here is an
abstract for the talk:
Several modal and first-order formalisms will be presented for expressing
facts about knowledge and belief. The novel features of these
formalisms arose from trying to express the reasoning involved in
solving the puzzle of the three wise men with spots on their foreheads
and the puzzle of Mr. S and Mr. P. These include the ability to
express that all a person knows are certain facts and to express
the effect of learning a fact. The relations among knowing that,
knowing what, and knowing about will be briefly discussed.
Due to a change in IBM security procedures, the gate by the research
building at IBM is only open from 8-9 AM, and again from 3-5:30 in
the afternoon. The only gate open all day is the main gate, further
up Cottle Rd. Here is a set of revised directions for getting to
IBM, which takes this into account:
Take 101 south and exit at Ford
Rd. (the exit is on the left, and comesafter Capitol Expressway and
Hellyer). Make a right off the exit ramp and after 100 yards or so turn
right onto a cloverleaf. Soon after
you exit this cloverleaf there will be yet another cloverleaf entrance
with a sign marked IBM. Take this cloverleaf too. After you exit the
second cloverleaf, turn right. (Ignore the sign that says IBM is straight
ahead. The gate that this sign is referring to will be locked in any
case.) You are now on Cottle Rd. Continue to the second traffic lights.
Turn left and enter by the main gate to IBM. Tell the security guards
that you are coming for the knowledge seminar which is being held
in the research building. To get to the research building from the
main entrance, take the first right, and go the equivalent of two
blocks to the white triangular building on your right, which is
just past the brown portables. There is visitor parking in the
front of the building, and extra parking in the rear. Again you will
have to register with the receptionist, who will point you to the
main auditorium where the seminar is being held.
We will continue holding the knowledge seminar on every second Friday,
starting at 1:30 rather than 2. The next speaker, on Febraury 10, will
be Ron Fagin from IBM.

He was definite about CMU..."
--John McCarthy
President's Quarterly Message
AI Magazine v.4 n.4. Winter 1983
Jon and John:
I simply cannot agree with this sweeping generalization.
In fact, evidence points to the contrary. During the
immigration course this year at CMU about two-thirds of the
27 first-year students indicated their primary interest in AI.
At least four of these students chose to work on the
Boltzmann Machine concept, something about as far from
a "big build-it-now" project as one can get. Others among
us are working in machine learning. Three first-year students are
working with Prof. Newell on research into a theoretical
Generalized Cognitive Architecture. A few of us have decided
to work on perception and manipulation, not in the area of
industrial applications but in basic research directed at
understanding how to build intelligent sensing and moving
machines.
To cite another counterpoint: We would not be students at
CMU or Stanford or MIT if our main interest were building AI
applications programs. It is quite possible with an undergraduate
or master's degree in computer science to find high-salaried
positions in any of a number of institutions working on AI
applications. One purpose of the Ph.D. is to become involved
in basic research. Among the graduate students here at CMU
there is no shortage of a desire to work on fundamental scientific
questions.

Carnegie-Mellon University has been named trustee of the "Fredkin Prize for
Computer Discovery in Mathematics", according to Raj Reddy, director of the
university's Robotics Institute, and a trustee of IJCAI (International Joint
Council on Artificial Intelligence) responsible for AI prizes. Reddy said the
prize will be awarded "for a mathematical work of distinction in which some of
the pivotal ideas have been found automatically by a computer program in which
they were not initially implicit."
"The criteria for awarding this prize will be widely publicized and reviewed by
the artificial intelligence and mathematics communities to determine their
adequacy," Reddy said.
Dr. Woody Bledsoe of the University of Texas at Austin will head a committee of
experts who will define the rules of the competition. Bledsoe is
president-elect of the American Association for Artificial Intelligence.
"It is hoped," said Bledsoe, "that this prize will stimulate the use of
computers in mathematical research and have a good long-range effect on all of
science."
The committee of mathematicians and computer scientists which will define the
rules of the competition includes: William Eaton of the University of Texas at
Austin, Daniel Gorenstein of Rutgers University, Paul Halmos of Indiana
University, Ken Kunen of the University of Wisconsin, Dan Mauldin of North
Texas State University and John McCarthy of Stanford University.
Also, Hugh Montgomery of the University of Michigan, Jack Schwartz of New York
University, Michael Starbird of the University of Texas at Austin, Ken
Stolarsky of the University of Illinois and Francois Treves of Rutgers
University.
The Fredkin Foundation has a similar prize for a world champion computer chess
system. Recently, $5,000 was awarded to Ken Thompson and Joseph Condon, Bell
Laboratories researchers who developed the first computer system to achieve a
Master rating in tournament chess.

John,
I just wanted to thank you again for giving your talk at the knowledge
seminar on Friday. Hearing it reminded me once more what a great
intellectual debt all of us working in this field owe you.
I still disagree one one of your conclusions. My feelings might well
be described as "Modal logic, si! First-order logic, no!". The
translation of such intuitively simple statements as "All I know is P"
into first-order logic seems to me cumbersome and unnatural.
I hope that Yoram's write-up of our solution to the Mr. S. and Mr. P
puzzle and the cheating wives puzzle will help convince you of that.
This is a subject we will no doubt return to in the seminars. It looks
now as if they will be held in the mornings (the vote is currently 5-0
in favor). I hope this means we'll see you down here again in the
near future.

Joe

I currently strongly prefer mornings, because
1) I'd rather hang around and chat in the early afternoon
than the late afternoon, and
2) I'd rather drive down in the mid-morning than the early
afternoon.
But these preferences are based on *very* limited experience with the local
traffic patterns. On the trip down for the first (morning) seminar, the
last five miles on 101 took five minutes to drive, while for the second
(afternoon)seminar, the five miles took over thirty minutes. If the delay
on the second trip was not characteristic, my preference is only weak for
mornings.

Subject: COMTEX contract
To: jmc@SU-AI.ARPA, bscott@SU-SCORE.ARPA
cc: bgb@SUMEX-AIM.ARPA
I had a call from Phoebe Huang at Comtex after she had talked with
Bill Osborne in OTL about the contract for reprinting the SAIL memos.
Osborne did not feel comfortable signing the contract for the University
because rights for books & other printed materials reside with
faculty. This is essentially what he said several months ago.
He had talked with Clive Liston who said essentially the same thing.
I suggested a rewording of the contract that I think will be less
intimidating. Instead of the guarantee & warranty that you have
the rights to the reports and are giving Comtex the right to reprint
the microfiche form, the new contract will say something to the effect
that you represent the authors, and without guarantee & w. you
are turning over the reports to Comtex.
Comtex needs some document in hand before they can turn over royalties.
This one is being drafted now (their lawyers may still screw it up),
but it sounds like it will be something you can sign. I'll sign for
the HPP reports one of these days and it doesn't bother me. Our
best protection seems to reside in the facts that
(a) The CSD has been distributing these reports widely for many years;
(b) The royalties are not going to an individual.
I think Comtex is doing the AI community a favor by making these
reports available. Our own library has a hard time keeping technical
reports (especially from MIT) in stock, for example. So I keep
encouraging them to find wordings in contracts that are mutually
satisfactory.

John,
This morning I received a call from Clifford Norton,director of
Performing Arts Center. He said no one from UT informed him of the
size of our conference or the nature of its operation, and did we
know that as an outside organizwtion we are required to sign a
contract.
This contract stipulates that an audit will be performed after
the conference and any surplus funds will be returned to UT.
He is sending me a copy of the contract and the profit/loss
statement which, I assume, is the audit form. I asked him
if we could apply a certain percentage of our operating expenses
to the p/l statement and he said yes. I also told him our UT
contact, Dean Heller, never informed me that we'd have to
sign this contract, and this fact was a real suprise to us at this
late date. IF we knew this fact a year ago, we would have chosen another site.
After this shock, I called Thompson Conference Ctr (location for
the tutorials) to see if that policy applied to the operation of the
tutorial program - no, it doesn't. Thank god! However, if we use any
rooms in the Perfoming Arts Center for tutorials, those revenues are
included in the overall p/l statement. So, I advised we don't have any
tutorials in the PAC. Now that I don't trust UT support staff to
convey accurate information or at least some basic facts, I've begun
to call hotels to see if we can hold the tutorials in their meeting
rooms. No answer yet.
I talked to Richard Fikes, and it's not clear how much
money we might have to return to the hordes at UT yet.
Some unknowns (ie UT services -electicians,technicians) are
difficult to determine. We could possibly return from $10-50k
or more (and this was the year, I had developed ways to save
money for the preparation and operation of the conference!)
It's to our advantage now to spend more so that we don't
have to give to UT.
I talked to Don and Ron, and both want to move the entire show
out of Texas. My only reservation is that it may very difficult
to find another site at this late date.
Feeling disgusted,
Claudia

Claudia,
I phoned Woody who will see what the top administration of
the University can do. You should expect a call from him, because as
long as he is going to the top, he might as well know the complete
set of problems including those we had earlier decided to live with.
The attitude of the top administration toward computer science is such
that I'm sure they'll try to solve it.

Dear John -
Thanks for your note. Yes, that is the sort of thing I would like to
do. Yes, I have thought (I think) about the difficulty you describe;
that is probably why I haven't starting writing code for any "small"
projects yet - I am making progress in understanding these sorts of
problems (I think), and want to sort out just what I am trying to do
before I start doing any of it. (I guess I'm looking for a paradigm,
of sorts).
What I have done is taken the note I gave you before Christmas and
expanded it to deal with some of these issues (you will be sorry to
hear); then I learned TeX and put it into that. If it's suitable
(even though I know you disagree with its probabilistic philosophy on
a basic level), what are my chance of publishing it?
My view, for what it's worth, is this: Knowledge acquisition (the problem
to which you refer in your message) consists of a variety of different
things. To paraphrase Bruner, there is the problem of concept acquisition
(birds can fly), and that of concept formation (just what is a bird,
anyway?). I think that concept acquisition is a statistical matter, and
is far and away the easier (and less interesting) of the two problems.
As for formation, the answer is usually linguistic, I think - we know
that there is some notion "bird" because we hear it mentioned, and then
go off and find out just what a bird is (by asking, if need be). There is
also "spontaneous" concept formation, which is harder still, and I do have
some half-baked ideas on this...
Let me finish finding the typos in my "article", and I'll inflict you
with a copy.

Have you been able to set a schedule for the remaining lectures
in your series? Will you be speaking at 3 today? You may have
announced this and I have just not seen it, but I would like
to include a schedule in next week's Newsletter and perhaps
circulate the information even earlier if it's available.
Thanks. -- Dianne

My last lecture co-incided with a philosophy colloquium, and I want to
avoid this conflict. I would be grateful if you would announce my next
lecture, the one on non-monotonic reasoning and circumscription for the
next Friday that does not conflict with this colloquium. Please repeat
the fact that it is one of four and repeat the abstract for this lecture.
Thanks for reminding me.

There would be no philosophy colloquium today, but it is too
short notice to gather people for your lecture. The Fridays on
which philosophy colloquia are scheduled are Feb. 10, Feb. 24,
March 16, April 13, and most of the Fridays in May.
So the next Fridays that do not coincide with philosophy
colloquia are:
February 17
March 2
March 9
March 23
March 30
etc.
I'll announce your next lecture for February 17, with the last
two on March 2 and 9, if those dates are available for you.

Dave Schlager just called from the Symbolics sales meeting in Vermont.
Among other things, the $14K price for 2 MByte memory increments will
come down to $9,900 for orders before 3/15/84 and then back up to $11K
for orders after 3/15. This gimick is apparently to try to generate
some orders to impress investors... Schlager is also trying to get
approval for us to buy 3600's with the DARPA configuration (4 MB memory
and 400 MB disk) at the $86K DARPA price without having to go through
ISI. No word on how that is going.
At the $10K "bargain", the net cost of our machines would be $78K if
we upgraded to 4 MB. How many are feeling the memory pinch already?

Let me ask you an important question. You may know that some of the PhD
students dislike having to read the AI Handbook in order to prepare for the
comprehensive. The last committee's active member in AI, Jitta Malik, has
proposed that the Handbook be deleted from the list and replaced by the new
edition of Winston's book. Of course, this change has to be approved by the
faculty and will not take effect until next years exams if it is so approved.
You could, however, commit yourselves now to giving an exam that tests only
that knowledge that can be had by reading either the Handbook (only the
sections on the list, naturally) and Winston. You could also allow us to
inform the students of this.
Do you want to so commit yourselves and do you want the students to be
so informed?

Siegman to have stated that he had met *precisely* one of the

other since. In any event, thanks for your eminently reasonable

By an overwhelming 8-2 vote, the preference seems to be for morning
seminars rather than afternoon seminars. The next knowledge seminar
will thus be on Feb. 10, at 10 AM, again in the main auditorium of
Building 28 at IBM. There will be two talks, one by Ron Fagin, and
one by Joe Halpern. I suspect we'll be done before noon (the second
talk should only last about 40 minutes). I have booked a small
cafeteria for lunch at IBM, for those who want to stay and discuss
some of the issues brought up by the speakers. The following knowledge
seminar will again be at 10 AM on Feb. 24. The speakers will be
Kurt Konolige of SRI and Yoram Moses of Stanford University.
On Mar. 9, our speakers will be Bob Moore of SRI, and Hector Levesque
of Fairchild. I'm open for suggestions for future talks.
Here are the abstracts for next Friday's talks:
On the semantics of updates in databases -- Ron Fagin
A database can be viewed as representing some knowledge about the world.
What happens to the state of knowledge when you try to update the
database? We show the kinds of problems that can arise in such
situations, and give techniques for dealing with
the insertion or deletion of arbitrary facts
(not just "single tuples") into a database.
Our techniques give insight into the problems of updating
views and of dealing with incomplete information.
The talk will be completely self-contained.
A beginner's guide to the modal logic of knowledge - Joe Halpern
We will give an overview of the techniques used to model knowledge
by means of modal logic and Kripke structures. In particular, we
show how changes in the axioms of knowledge are reflected in
the "alternate worlds" relation. We concude with some discussion of
the advantages and shortcomings of Kripke models. As the title suggests,
the talk will be introductory and self-contained, and is to some extent
preparation for future talks which will use modal logic.

Question to JMC:
If Russia's military complex is usurping an ever increasing share of
their GNP (a clumsy paraphrase, but refer to original bboard message for
exact statement by JMC), and that is bad for the US, should we not
discontinue selling them food, in order to force them to divert more
national effort into feeding themselves?
If relative military strength were the sole consideration, this might
be so, but we aren't at war with them, and the game isn't zero sum.
Therefore, trade and some two-way sharing of science and technology
is beneficial to us as well as to both the Soviet people and the Soviet
Government. I'm not sending this to bboard now, because I intend to
reply at length to JMM after adequate thought.

I just finished talking to Dean Gleason, Assoc. Dean in UT's College of
Natural Sciences about the surplus funds issue. At this point, they have not
developed any concrete solutions but continues to assure me that they (the
Vice President of Academic Research and Gleason) want this conference
on campus. He even suggested they are quite willing to bend
UT's rules and regs for this particular conference. I told him our
association does not want to be any party to any subterfuge.
I will going to Austin next week and will meet with Gleason and another
Assoc Dean to develop some options. After that meeting, they hopefully
will prepare a letter which will outline our financial responsibilities
to UT. I don't know if this letter will take us off the hook yet; I've
got a call into our attorney to get her opinion.

Welcome to the comp committee! I will do my best to make the time you put
into our joint work worthwhile. And to make the job less onerous,
I've divided our committee into two parts; another subcommittee is
going to take care of the programming projects, while the rest of us
are charged only with making up and administering the exam, and revising
the reading list for the spring comp.
Our subcommittee is, in turn, parceled up into six parts having primary
responsibility for the six sections of the exam.
NA: Rob Schreiber, Billy Wilson % Numerical Analysis
AI: John McCarthy, John Lamping % Artificial Intelligence
SW: Keith Lantz, Per Bothner, Tracy Larrabee % Software
AA: Don Knuth, Dave Foulser % Analysis of Algorithms
HW: Manolis Katevenis, Stefan Demetrescu % Hardware
MTC: Christos Papadimitriou, Martin Abadi % Math Theory of Computation
Of course, we'll all work together on the exam as a whole.
I have appended to this note a copy of the reading list the students have
received, and the famous "charge" to our committee. I suggest that you get
from Marilynn Walker the copies of the last two exams, since we will be
making a similar one (namely, six one-hour exams, one for each area,
closed book).
At the moment there is only one piece of urgent business: Everybody who will
take the comp wants to know when it will be given. I believe it is best to
give it at approximately half-year intervals, hence I propose choosing the
latest possible date in May. (The winter comp was given January 14 and 15).
What do you think about the following exam dates?
Saturday, May 19, am: SW, AA, NA.
Sunday, May 20, pm: HW, MTC, AI.
If I hear no strong objections by next Friday (Feb 17), I'll announce
these officially. As last year, we will make exceptions in exceptional
cases (e.g., if somebody needs to take it a day earlier or later for
religious reasons).
I am arranging for some students to pre-take the exam.
In addition, each subcommittee should try to find one student to
pre-test their section.
At the moment I favor the following approach: Each of the six
subcommittees gets together on
their own to come up with possible exam questions. Then I meet with each
of the six subcommittees to help refine the questions, after which I'll present
Phyllis with an edited draft of each question. Then the whole committee
will look at these drafts, and refine everything as a group. Then
the guinea-pigs take our trial exam. Then we grade his work and make
appropriate refinements. Then we administer the real exam.
If you agree with the suggested strategy, I propose the following rough timetable:
Now -- Mar. 12: Six small subcommittees get together and make rough drafts.
Mar. 12 -- Mar. 16: Each subcomittee meets with me to make less rough draft.
Tuesday Mar 20, 12:30: Whole committee refines it (expect a 3.75-hour meeting)
Sometime during the rest of November: Student guinea pigs take it
Tuesday April 10, 12:30: We finalize the exam (another meeting)

What should you do now? Please send me a note, so that I know you have
received this message. In your note, tell me if you cannot come to Tuesday
meetings from 12:30--4:00 (there will be 2 before and 2 after the exam)
And DO please meet with the other member(s) of your subcommittee, before
March 12, so that you'll be ready with a rough draft when Shanee
calls you to set up appointments with me during the week of March 12.

\area{PREPARATION}
The document ``Charge to the Comprehensive Exam Committee,'' available from the
department office, describes general policy. Previous exams, also available
from the department office, provide a good source from which to study.
The comprehensive exam is meant generally to cover the material from
the followiwng courses: 155, 161, 162 (algorithms and data
structures); 223 [224 is recommended in addition] (artificial
intelligence); 111, 112, 311 (hardware systems); 137A (numerical
analysis); 142, 143, 146 [246 is recommended in addition] (software
systems); and 154, 156 [206 is recommended in addition] (theory of
computation). Since the precise content of these courses varies, the
actual scope of the exam will be determined by the references above.
The exam will also assume a certain mathematical sophistication and a knowledge
of programming. Proofs of correctness for simple programs may be required.
The programming knowledge required will be Pascal, LISP, and an assembly
language. Nonsmoking and smoking examination rooms will be scheduled.
\area{PROGRAMMING PROJECT}
Students in the M.S. and Ph.D. programs (and Ph.D. Minor students who
have passed the written examination) must prepare a programming
project of sufficient complexity and quality to demonstrate competence
in computer programming. This project must be supervised and endorsed
by a member of the Computer Science Department faculty and submitted
to the comp committee for final approval. The project must be written
at Stanford by the student, working independently. It is due,
approved and signed by the supervising faculty member and given to the
Administrative Assistant for Academic Affairs, before the end of the
student's second year, specifically before the middle of spring
quarter.
The project must exhibit the use of sophisticated algorithms and data
structures and be well documented. Programs will be judged on the
basis of correctness, efficiency, clarity, and style. The project may
be the result of CS 293 work, although it need not be. It should
represent at least 3 units of work. Before starting the project, read
the ``Requirements for the Comprehensive Programming Project''
available from the department office.

@Begin(Body)
This is an edited version of the Charge to the Comprehensive Exam
Committee drafted in November, 1978 by Denny Brown. Older versions
may be found as indicated at the end of this memo.
During 1978 and 1979, students expressed dissatisfaction with some
aspects of the comprehensive exam. In response to some of the issues
raised, an ad hoc committee composed of Jeff Barth, Frances Yao, Terry
Winograd, and Al Spector was created in Spring, 1978. Their proposals
were presented at the June 1978 faculty meeting. In this memo I will
attempt to present a charge to the comp committee that incorporates
the new policies agreed upon at the June meeting with standard
operating procedures of previous comp committees. This is not
intended to be a definitive document; instead, it is my attempt to
bring together what I believe to be "current policy" concerning the
comprehensive exam.
Additional proposals were presented by the students at the June 12,
1979 faculty meeting. The text of these proposals are attached to the
June 12 faculty meeting minutes. The faculty passed a resolution at
the June 12 meeting. The resolution appears below.
The form of programming portion of the exam was modified at the June
10, 1980 faculty meeting. It was decided to do away with the five-day
programming problem. Instead, a student will submit a program to the
comp committee for approval. Text of the resolution appears below.
@Begin(Enumerate)
The comprehensive exam will be given in two independent parts, the
written exam and the programming project. Students must pass both
parts of the exam at the appropriate level. Grading of the two parts
will be independent of one another, so that a student may pass the
written exam at one time and the programming project at another (in
either order.) The comp committee will try to schedule the exams to
minimize conflicts with courses. The 1979 written exams were given on
Saturday, January 26, and Saturday, May 10. The 1983 written exams
were two-day exams with three one-hour sections on each day; they were
given on the Saturday-Sundays of January 8-9 and May 21-22. The
committee may revise the schedule. The dates should be decided upon
at the first committee meeting.
The comp committee will be composed of 6-10 faculty members and
research associates and 4-6 students who will serve for an entire
academic year. The terms of service will be staggered so that about
half of each committee will have served on the previous exam and about
half will be new members. The committee should be collectively
competent in the six areas of the exam, namely Algorithms and Data
Structures, Artificial Intelligence, Hardware Systems, Numerical
Analysis, Software Systems, and Theory of Computation. They will
administer two written exams and grade programming projects. They
will revise and publish a list of readings and suggested courses to be
used for the exams in the following year. They will prepare a charge
to the following year's committee reflecting additions or
modifications to this charge.
The comprehensive exam serves three purposes. It is (1) the principle
breadth requirement in the Ph.D. program. It is (2) the principle
"quality control" feature of the M.S. in Computer Science program. It
is (3) the only requirement for a Ph.D. minor in Computer Science.
The exam has traditionally been scored as follows:
@Begin(enumerate)
Ph.D. pass - student has a high total grade and has exhibited
acceptable competence in all six sections of the exam.
Conditional Ph.D. pass - student has a high total score, but is
deficient in one of the six sections. Explicit criteria for removal
of the deficiency are given including name of the person who will
certify satisfaction of the condition.
Masters pass - student's total score is sufficient for Masters or
Ph.D. minor accreditation. Breadth is not an issue for such a pass.
Fail - student's total score was unacceptable.
@end(Enumerate)
Exams are graded without knowledge of the students' identities.
Consequently, students in the M.S. program may pass at a "higher"
level. (This does not have any bearing on the student's admission to
the Ph.D. program. Admission is an entirely separate issue.)
Similarly, Ph.D. students may pass at the Masters level. (This would
enable the student to take the Masters degree.)
It is required that Ph.D. students pass the exam at the Ph.D. level
within the first two years of full-time study. Masters students often
plan to spend only one year in the Masters program. The reading list,
list of suggested courses, grading criteria, and the composition of
the exam itself should make it possible to pass the exam at the
Masters level after a single year here. Masters students have been
informed, however, that many students do not pass the exam in the
first year. There has been a tendency to increase the number of
courses recommended for the exam. Constraints upon the expected
length of programs should be kept in mind. At the January 18, 1980
faculty meeting, the faculty voted that Masters students be allowed
only four attempts to pass the exam. This is roughly in keeping with
the two-year limit for Ph.D. students. My (DPB) suggestion is to
limit the scope of potential questions to core issues in each area,
while continuing to require solid performance on the exam.
Don Knuth pointed out that the first exams were four-hours. The
expansion to six hours was a reasoned decision. The 78-79 committee
specifically stipulated that the exam should be a six-hour exam. This
should provide a choice of problems to work on in each section.
Nobody is expected to (come close to) finishing the entire exam.
Each question on the written exam should be graded by at least two
members of the committee; at least one reader should be a faculty
member. Grading of exams should be prompt (say within a week) so
that students can make appropriate plans based on the results of the
exam. The programming project should be graded by at least one member
of the committee but by someone other than the student's advisor.
At the June 1978 faculty meeting, there was a suggestion that a
separate committee administer the programming problem. For this year,
the committee may want to designate a subcommittee to handle the
programming problem. In the charge to the 79-80 committee a
recommendation as to whether the exam committee should be split into
two separate committees would be appreciated. No such recommendation
was given by the 78-79 committee, so we will assume that the entire
committee will be responsible for the programming problem.
@begin(Multiple)
The following motion was passed at the faculty
meeting of June 12, 1979.
@begin(Quotation)
If a Ph.D. student fails twice, or has only one chance left, the
Comprehensive Exam Committee is to arrange a meeting soon after the
exam with the student and his/her advisor to discuss a plan of action.
@end(Quotation)
The key argument leading to this motion was that the comp committee
has a great deal of assembled expertise on the issue of the student's
competence. They know what was expected on the exam, and they know
exactly how the student performed, both absolutely and in relation to
other students who took the exam. They are in the best position to
determine the cause of the student's failure, and to recommend
remedial action. Suggested courses of action include: (a) encourage
the student to study hard, paying special attention to weak areas, and
take the exam again at the next opportunity, (b) if the committee
believes that the student is more knowledgeable than was demonstrated
on the written exam, an alternative method for satisfying the
comprehensive requirement may be substituted for re-taking the written
exam. Examples (not exhaustive) of such alternatives are (i) an
immediate oral exam covering any area of the committee's choosing to
determine if the student's poor performance might have been caused by
poor test-taking skills, or (ii) alternative written work without the
exam's time pressure, or (iii) other reasonable requirements which the
committee, the student, and the student's advisor agree upon. In
general, the exam committee should consider that its task is not
limited to administering the written exam and programming project.
Included in the responsibility is that of diagnosing the cause for
failure of any Ph.D. student who is close to the end of the rope.
@begin(Quotation)
Note: The motion as passed explicitly mentions Ph.D. students who are
in danger. The committee may (or may not) want to consider Masters
students who may not perform well on timed-written exams. A similar
mechanism may be called for in such cases.
@end(Quotation)
@end(Multiple)
@begin(Multiple)
The following resolution, passed at the June 10, 1980 faculty meeting,
gives the new policy on the programming exam.
@begin(Quotation)
Students in the M.S. and Ph.D. programs (and Ph.D. minor students who
have passed the written examination) must prepare a programming
project of sufficient complexity and quality to demonstrate competence
in computer programming. This project must be supervised and endorsed
by a member of the Computer Science Department faculty and submitted
to the comp committee for final approval. The project must be written
after entering the program at Stanford by the student, working
independently.
The project must exhibit the use of sophisticated algorithms and data
structures and be well documented. Programs will be judged on the
basis of correctness, efficiency, clarity, and style. The project may
be the result of CS293 work, although it need not be. The project
should represent at least 3 units of work.
@end(Quotation)
The 1981 committees should decide on a mechanism for implementing this
policy.

deletions, additions, etc. To date you have not returned this to her.
It is requested that this information be returned by Monday, 2/12, at

in the C&D process, and as I am sure you are aware, it is not just the
Publications Office that suffers.
Please take the few minutes it requires to simply look over what Kathy

I believe that it is impossible to change the reading list
this year, because it has already been "promissed" to students. What we
can do is to limit the exam to the intersection of the old reading
list and some other book, and announce this unofficially. I haven't
seen Rich's book, but certainly prefer Winston to the
Handbook, on the basis of reading the first edition

plan.pl[1,LEP] now has a better version. The old version used to
leave around old assertions if the plan failed. I hope to add colors
soon. if you try to build a tower with block1, block2, block1 it
succeeds by undoing what it did to build the bottom of the tower.
I'm thinking about how to fix that.

Also I
was always game for a challenge.
MCC is very important to UT and I would like to help see that the
AI part "gets started right". The university has given their
blessings to this, but are anxious that I continues to "be a
part of the University", and reuturn.
My first loyalty is to the University. I very much like it here
and can't imagine leaving for good. I also want to help in any way
that I can, their effort to build.
I strongly support the effort to attract you to UT even as a
visitor here next year. You can certainly consult at MCC if I go
there, whether or not you come to UT. Perhaps when you and Carolyn
come to Austin this Spring, you can go with me to MCC to discuss
their mission (dont take this as a duty of some sort but just an
opportunity - also they of course pay consulting fees).
Best regards,
Woody
Oh yes, I feel that the problems with AAAI and money are being solved
in a fair and honest (and legal) way. I have talked with VP Fonken
and his word is like gold to me. Also Austin Gleeson (Asso. Dean and
Chairman of the Physics Department) is right on top of it and
determined to see that AAAI is made happy. Of course Claudia is
aware of all of this. During her trip next week I hope everything
can be settled.

This is a content note on an idea generated by yesterdays seminar.
In the semantics of OLP, I attached a certain kind of codition to
activity verbs. E.g., to MULPTIPLY I assigned the condition:
In SIT: at LOC2: multiplies, IND1, IND2, IND3; 1
at LOC3: result, INDR; 1
INDR = IND2 x IND3
LOC3 = re(LOC2)
and commented that this seemed odd, since it brought in the property
of being a result into the semantics of MULTIPLY. It was necessary in
order to get the various part of the discourse to fit together in a
coherent way. Michael's question yesterdays, and the discussion that
followed, disscussion points to a more natural way to do this, that
might suggest a more general treatment of things like moving the
coffee pot to wear out the sweater, etc. The rather obvious idea is
to clearly distinguish what constituts an action from what else that
action may involve, because of various necessary, nomic or
conventional constraints on the agent and his world.
This this simple example, consider the following necessary structural
constraint:
involves, E,E'; 1
where E is basically the first line of the above, and E' the other
three. That is, there is a structural constraint that in an
individual actually multiplies a by b in an interval I then at the end
of that there is a result and the result is the product of a and b.
Now factor the problem of the semantics of the command into two parts.
The condition on multiplies is just the first line, but there is a
general condition that all computatations have to meet the above
constraint. Then there is always a result around when needed, but it
is not brought in by the lexical semantics of MULTIPLY.
To generalize this, there are certain constraints that one type of
action ACT involves certain types E of consequences. Such constraint
can be exploited to achieve situations of type E by doing things of
type ACT. (This does not mean that every action of type E is thus also
of type E, of course, to answer Michael's objection.) But note that
this can also block an action of type ACT, if something blocks
situations of type E. E.g., going thru the door involves there being
nothing blocking the door (if I understood the film, this was Shakey's
assumption), so when Shakey encountered a blocking situation, he
abandonded that particular type of action.

I agree with you completely. My master's work concerned the modeling
of Kansas weather data based on a historical record extending back
for a hundred years. The results showed that there is a correlation
in the temperature patterns that extends back for a couple of days
(in addition to seasonal and other easily predicted long-term effects),
but that precipitation appears nearly random if you do not model the
spatial effects of fronts moving in.
The Farmer's Almanac is obviously based on seasonal averages and the
fact that readers won't object if a predicted event is off by a day
or two either way. Predict five rains in June, each plus or minus
two days, and you've covered the entire month. Anyway, the algorithm
they use is a trade secret.

1.IN THE PAPER YOU MENTION THAT "MATERIAL WAS CUT OUT OF VOLUME 1".
IT SEEMS THAT ALL MATERIAL WHICH WAS INTENDED FOR ALGOL WAS PUT INTO
A VOLUME 1 AND THE REST WAS "CUT OUT".DO YOU REMEMBER WHAT ELSE WAS
CUT OUT?
2.WHEN REALLY YOU BECAME INVOLVED WITH ALGOL? IS THIS PAPER OF JUNE 10TH
IN 1958 A REGULAR CONTRIBUTION OR ONLY A PROPOSAL OF SOMEBODY (YOU) WHICH
IS STILL OUTSIDE?
3.IN THE FIRST LISP MEMO THE MAPLIST FUNCTION IS DEVELOPED WITHOUT LAMBDA-
NOTATION.I HAD THE VIEW THAT IT WAS WRITTEN IN SEPTEMBER 58.IF I SEE NOW
LAMBDA-NOTATION AS PART OF YOUR THINKING ALREADY IN JUNE 58 I ASK MYSELF
IF THIS DATE IS RIGHT.THE DATE (OF THE MEMO 1)WAS NOT PRINTED ON THE MEMO
BUT WRITTEN BY NAT ROCHESTER.
HERBERT
It seems to me that I was a part of the U.S. Algol 58 committe, but I was
not one of those who went to Europe, and I didn't take an active part.
However, it is also possible that I didn't become associated with Algol
until after the 58 meeting. I'm pretty sure that at the time I sent
the memo to Perlis and Turanski, I must have been a member of the Algol
committee. I'll look at the memo and see if I can recall something
else. At present I don't remember doing differentiation without lambda.
Note that it isn't necessary to use lambda to define maplist - only to
use it.

Dear Professor McCarthy:
I am writing a dissertation on computer-based medical decision
analysis, and I have question about formal logic that you might be
able to answer. The point seems quite intuitive to me but, after
checking with Mike Genesereth (with whom I have done quit a bit of
work), it appears that it may not be as simple as I originally
thought. I have taken the liberty of sending you this message in
hopes that you might provide me with some insight or, at least, some
pertinent references.
My claim is that it is not possible to deduce a PRESCRIPTIVE assertion
from a system of axioms and theorems, none of which is prescriptive.
Therefore, if we describe a situation with a set of factual statements
(axioms), and we then apply a formal decision method (a set of
theorems) to this description, the only way in which we can obtain a
prescriptive conclusion is if the formal method contains AT LEAST ONE
THEOREM whose consequent is PRESCRIPTIVE.
I would appreciate your comments on the above claim.
Thank you for your help,
Sam Holtzman
(HOLTZMAN@SUMEX)
-------
I have thought about the matter before, and my opinion is the same
as yours. Some philosopher, probably nineteenth century, put it
this way, "You can't derive an ought from an is". However, as soon
as you admit one ought into your axioms, then with the help of facts,
you may be able to derive many more oughts. The people who thought
they were derving oughts from ises always let one ought, e.g. survival,
sneak into their systems. The relevant technical result is presumably
much simpler. Given an arbitrary predicate, OUGHT in the present
case, we cannot derive a conclusion in which this predicate occurs
postively unless it occurs positively in some premiss. Intuitively,
it would seem that there are stronger theorems. Under suitable conditions,
we can allow rules that have P in both premiss and conclusion but
still be unable to derive any P(a) unless there is some P(x)
unconjoined with not P(y) somewhere in the premisses.

I have been having some discussions with Dick Gabriel, Ed Feigenbaum,
Joe Oliger, folks at Los Alamos, ... about potential interesting
research areas. Some of these include:
1. LISP on Multiprocessors (such as the HEP, the ELXSI, ...)
2. A modeling environment for real-world physical problems (potentially
the confluence of AI and numeric supercomputing)
3. Bringing the Palladio experiment into a high-performance environment
and expanding it for potential use in an operational environment
(CIS)
4. Performance projection and analysis of the above (both to eventually
develop means to predict performance of planned applications and
to contribute to future improved architectures and system organizations
for such applications)
I would appreciate the opportunity to "bounce" some of these ideas around
with you, and to see if you would want to be involved (or take on) any
of them. Tomorrow (Wed.) am, Bill Buzbee from Los Alamos will be with me
starting about 9am. We will be discussing these topics also, since one of
the immediate possibilities is a joint proposal where Stanford and
Los Alamos would approach DARPA for funding of some of the above. Our
discussions to date are certainly not firmed up, but there are some
strong common interests. (If you are interested in joining all or
part of my discussions with Bill, you are welcome - or we could come
to visit you.) Except for that meeting, I will be available tomorrow
until 3:00pm. I will be out of town either Thurs or Fri on IEEE
Computer Society business (probably Thurs). Monday (20th) I am booked,
but have most of the rest of that week open.
(For your information, I have been at Stanford for just over 1 year now -
am Assoc. Prof (Research) in EE - Computer Systems Lab. I am actively
participating in CIS since I was hired to assist Meindl in planning
CIS support facilities and systems design capabilities (among other things).)

Steve,
I'm interested and will call you tomorrow, probably in mid-morning.
Dick has no doubt told you about our work, originally mine and now
almost entirely his, on Lisp for multi-processors. Perhaps I'll have
more ideas in that area. I'm also interested in combining AI and
numerical computing. Edward Teller asked me, a year or two ago, to look
at a proposal by Chandrasekharan of Ohio State on an AI system for
helping reactor operators, and I concluded that the AI proposed could work well

I had considered the same initial idea (mutating a program) but more
LITERALLY than you did: one of Eurisko's domains is Lisp Programming.
In it, it did a few interesting things, such as
(1) Coalesce PROGN: (LAMBDA (Z) (PROGN Z Z)), which got it the notion
of "side effects"
(2) Coalesce NCONC: (LAMBDA (Z) (NCONC Z Z)), which makes it easy to tell
if Z (was a) list, by printing out Z and waiting a few minutes to see if it's
done yet.
(3) Notice that EQ is a specialization of EQUAL, so it hypothesized that
(OR (EQ x y) (EQUAL x y)) might be faster than EQUAL alone, since EQ was
much faster than EQUAL. Strangely enough, it was correct (!!) and that
turned out to be a bug in the then-volatile Interlisp-D language (now fixed.)
The more genral sense of "program", however, had not occurred to me as
suitable, but it certainly is. Moreover, Eurisko might well find some
nonstandard instances of the generalized algebraic structures it defined,
examples in wargaming, programming, oil spill spreading, and other domains
it already has knowledge of (and simulators for).
Thanks for the suggestions, John.

See you then.
A Deduction Model of Belief -- Kurt Konolige
Most current formal models of belief for AI planning systems are
derivatives of a possible-world semantics for belief. However, this
model suffers from epistemological and heuristic inadequacies.
Epistemologically, it assumes that agents know all the consequences of
their belief. This assumption is clearly inaccurate, because it
doesn't take into account resource limitations on an agent's reasoning
ability. For example, if an agent knows the rules of chess, it then
follows in the possible-world model that he knows whether white has a
winning strategy or not. On the heuristic side, proposed mechanical
deduction procedures have been first-order axiomatizations of the
possible-world semantics, an indirect and inefficient method of
reasoning about belief.
A more natural model of belief is a deduction model: an agent has a
set of initial beliefs about the world in some internal language, and
a deduction process for deriving some (but not necessarily all)
logical consequences of these beliefs. Within this model, it is
possible to account for resource limitations of an agent's deduction
process; for example, one can model a situation in which an agent
knows the rules of chess but does not have the computational resources
to search the complete game tree before making a move.
This talk will be about the deduction model of belief and its
formalization by modal logic families. I will discuss some of the
following issues:
1. the correspondence between the deduction and possible
world model;
2. a theory of ignorance;
3. a theory of introspection.
A formalization of the Wise Man Puzzle and a derivative, the
not-so-wise-man problem, will also be given.
Knowledge and Common Knowledge In Distributed Systems -- Yoram Moses
The notion of knowledge in a distributed environment is fundamental to many
issues in distributed computing. Many tasks in a distributed system
directly involve the achievement of specific states of knowledge and others
crucially depend on a variety of constraints on the state of knowledge of
the parties involved. Communication in a distributed system can be viewed
(and in some cases should be viewed) as the act of transforming the system's
state of knowledge. Of particular importance is the notion of Common Knowledge,
which can be viewed as the generalization of an individual's knowledge to a
group. Common knowledge is inherent in notions such as agreement.
We investigate the conditions needed to achieve common knowledge of a fact in a
distributed system, showing that there are practical problems in achieving it
in actual systems. We present a new related notion, called epsilon common
knowledge that corresponds to the knowledge state achievable in some reasonable
systems. We show how this notion can be incorporated into a logic of knowledge,
and compare it with common knowledge. We discuss the logical and practical
implications of this to actual knowledge and action in distributed environmemts.
This work is joint with Joe Halpern of IBM San Jose.

Dear Professor McCarthy:
Thank you for your note on proving OUGHTs from ISes. In
particular, I agree with your statement:
"Given an arbitrary predicate, OUGHT in the present
case, we cannot derive a conclusion in which this
predicate occurs positively unless it occurs positively
in some premise".
I am glad to find that my intuition agrees with yours.
For your information, I am using this argument to claim that,
at present, our best choice for a NORMATIVE theory of decision is the
formal methodology known as "Decision Theory," which is based on
subjective probability as a measure of uncertainty, and on the
principle of maximization of expected utility (MEU) as an "action
axiom" (i.e., the axiom with an OUGHT in it). To me, any action axiom
is a leap of faith, because it makes a statement about the real world
on the basis of a formal condition. As such, it must be accompanied
by a convincing argument justifying its wisdom; otherwise it is pretty
useless other than as dogma. My claim is founded on the fact that
people like Leonard Savage have given powerful arguments in favor of
MEU, the likes of which do not exist (to my knowledge) for any other
action axiom.
Knowing that an action axiom (and, hence, a leap of faith)
MUST exist in any normative theory of decision is crucial to the
above argument. Otherwise, it would be possible to build such a
theory without the leap (as many statisticians have tried to do), and
the need for justification would disappear, at least in principle.
Given your comments, I feel confident that an action axiom is a
necessary part of normative decision theories.
Again, thank you for your help.
Sincerely,
Sam Holtzman.

HOLTZMAN@SUMEX-AIM
ought and is
I don't agree with MEU - either as describing actual human behavior,
as a norm for human behavior, or what should be built into computer
programs. I think my objection is different from those usually given,
and it applies to any unitary ought rule, i.e. a rule deriving all
oughts from a single principle.
People appear to have a wide variety of rules, learned at different
times, determining their goals and what ought or ought not be done
to accomplish them. This can and does lead to conflicts between what
the different rules advocate. Since one of our dislikes is internal
conflict, one human goal is to discover and adopt a general rule that
will encompass all the specific rules and enable us to avoid internal
conflict and also to provide a justification for others. However, I
don't believe this can be done except for in limited models of reality
parametrized in advance. My reasons for believing this are still somewhat
vague and are related to a whole collection of ideas about non-monotonic
reasoning. However, here are a few remarks.
1. When someone formulates a general rule, it is typically criticized
by bringing up examples that the author of the rule hasn't thought of.
Often concepts that the author thought were clear turn out to be
ambiguous in the circumstances postulated in the examples.
2. That our concepts have limited applicability is the normal intellectual
situation of humans and it will be normal for machines also. We can
only formulate rules governing small (in some sense) models of
certain aspects of the world. These rules may be unambiguous
in the cases encountered in existence of a particular human or machine,
but there is no reason to suppose that they won't be ambiguous
in cases that might arise.
3. Let me propose a semi-mathematical problem. Suppose that we have
a collection of a dozen or so ought rules. Suppose that we have
a certain parametrized set of circumstances, and suppose that
the prescriptions of the set of rules are unambiguous and intuitively satisfactory
in these circumstances. Suppose now that we propose to expand
the collection of circumstances considered. It may happen that
the rules become ambiguous or that the results are intuitively
unsatisfactory. Is there necessarily a more comprehensive rule
that will give even approximately the same results in the limited
circumstances, which can be compactly formulated and which is
intuitively satisfactory. My opinion is that this is not guaranteed.
Therefore, when we invent rules of behavior for robots, we will have
provide a collection covering the circumstances we can anticipate,
and we can expect conflicts when certain unanticipated circumstances
occur.
4. But surely, you may argue, the robot will exhibit some behavior
in the unanticipated circumstances, and isn't this the general rule.
Yes, but the robot's behavior may be intuitively unsatisfactory.
In particular it may depend on adventitious aspects of the situation,
such as which horn of the dilemma was encountered first.
I don't know whether any of this is relevant to the problems you are
trying to solve, so I'll stop.

Dear Prof. McCarthy
I am a staff member of SRI International, spending this year in the
Department of Electrical Engineering and Computer Science at the Techn-
ion in Israel. Next year I will be back in California and would like to
teach a class in your department, possibly as an Industrial Professor.
My area of interest is data communication networks and the subject
of the class I have in mind is random access techniques in data communi-
cations. This is a mathematically oriented course for upper graduate
students which I developed and have taught twice here in Israel. A gen-
eral syllabus is attached.
If such a class does not fit the department's repertoire, I shall
be glad to teach any class in the data communications area.
As to references, Prof .Z. Manna knows me well, and of course Dr.
Don Nielson and Mr. Jack Goldberg of SRI. Additional references can be
provided if required.
Sincerely,
Attachments.

Technology, techniques, and design paradigms of electronic office
information systems. The objective is to present a coherent and cohesive
foundation for the understanding and analysis of office systems and
their implementation. Topics include: basic components and media such as
word processors, workstations, PBXs, and local area networks; office
firmware such as RasterOps, virtual keyboards, phone handlers, and
window managers; office system elements such as document editors, mail
systems, calendaring systems, and distributed servers. The course will
describe and discuss issues of user interfaces, user programming, office
modeling, and the social / organizational structures within which the
technology must exist. Prerequisites: computer organization (e.g.
cs111,cs112), computer software (e.g. cs142,cs146).

I believe I have some good news to tell you. The University
has agreed to allow the AAAI to keep our surplus funds for
the conference (incl all 3 programs). We agreed that the
AAAI will pay for all out-of-pocket expenses ( ie UT police
services, electicians, guides, room rental fees).
These points of agreement are expressed in the following letter (note:
the letter is from the AAAI to UT) and the Revised Building Use
Agreement form. I've been assured that the letter will be signed off
by the VP of Academic Affairs and the VP of Business Affairs. This
letter will act as agreement of our mutual understanding of the AAAI's
financial responsibilities to UT.
My only reservation regarding this matter was the possibility of an
audit by UT auditors. Their response was that they control the
auditors, and, anyway, audits of activities in the Performing Arts
Center are only concerned about fraud and theft of tickets.
I admit I had some serious reservations about this matter.But,when I
met with Dr. Fonken and UT legal counsel in which they explictly
stated we could keep the extra surplus and that both VPs would
sign off on the letter and revised agreement, my reservations
disappeared. One thing I was asked to do was to tell you to keep
this agreement quiet. The University usually doesn't accomodate
outside groups as they have in this case.
I'd like to hear your comments soon so that we can proceed with
the preparation with the conference.
Regards,
Claudia
P.S. Let's thank Woody for getting in there and getting to the right
people in the University.

Dear Vice Presidents Fonken and Franklin:
The American Association for Artificial Intelligence (AAAI) is holding
its national meeting at Austin, Texas in 1984. The meeting is
scheduled to take place from August 6-10, 1984. Although the meeting
headquarters and registration site is in the Villa Capri Hotel [ This
is one of the concession I had to make; originally registration was to
occur on campus; pls note the Villa Capri is a 3 min walk to the
Performing Arts Center; at least at the Villa, we will be able to sell
conference proceedings and memberships], the association has requested
use of the facilities at the University of Texas at Austin for some of
its sessions. The Depts of Mathematics and Computer Sciences and the
College of Natural Sciences are co-sponsors of this event. The
facilities we intend to use are the Performing Arts Center for large
plenary sessions and rooms in the Thompson Conference Center for
tutorials. As a part of the conference we are sponsoring the displays
of new equipment related to the field of artificial intelligence in
the scene shop of the PAC. Our estimated attendance is more than 2000
computer scientists who will be accomodated in the hotels in Austin
and in Jester Center.
I attached an estimated income and expense statement fo r the
operation of the conference on your campus. We understand that
the only financial obligations of AAAI to the University in regard to
the conference will be indicated in the items of the budget.[ ie
facilities costs]. In addition, this letter shall serve as the only
agreement between the AAAI and the University in regard to
financial matters. We would appreciate your review of the attached
budget and outline of the conference plan stated above. If it
appears acceptable, please indicate your review and acceptance by
signing below and then return it to me for your records. Additional
copies are attached for your files.
We appreciate the hospitality of the University in sharing its
facilities for our conference. This ......

Subject: Bird axioms
To: jmc@SU-AI.ARPA
It occured to me during your lecture today that I'm handling the blocks
world in a different way that you were doing the bird example. Below
are the same axioms expressed in the two ways. The second way will
make the same inferences, but perhaps the circumscription doesn't work
correctly?
The way JMC does it:
~ ab aspect1 x -> ~ flies x
bird x -> ab aspect1 x
bird x & ~ ab aspect2 x -> flies x
ostrich x -> ab aspect2 x
ostrich x & ~ ab aspect3 x -> ~flies x
A simpler way:
~ ab aspect1 x -> ~ flies x
ab aspect1 x -> flies x
bird x & ~ ab aspect2 x -> ab aspect1 x
ostrich x & ~ ab aspect3 -> ab aspect2 x
-------

abnormality
It seems to me that with your axioms, minimizing ab won't lead to the
conclusion that Tweety, known only to be a bird, flies. We will
just get
ab aspect2 Tweety or ab aspect1 Tweety.
I still haven't gotten around to reading your Prolog program, but I
hope to do so this weekend. We should get together next week anyway,
though I'll be gone Tuesday and Wednesday. Thursday afternoon
after 3 might be ok if convenient for you.
∂17-Feb-84 2308 PACK@SU-SCORE.ARPA is-a hierarchy solution?
Received: from SU-SCORE by SU-AI with TCP/SMTP; 17 Feb 84 23:07:58 PST
Date: Fri 17 Feb 84 23:07:48-PST
From: Leslie E. Pack <PACK@SU-SCORE.ARPA>
Subject: is-a hierarchy solution?
To: jmc@SU-AI.ARPA
I'm not sure what question you were asking, but here is a solution to
some related problem.
Rules for expressing a general is-a hierarchy. We must know about the
direct ancestor of a particular class in the hierarchy. I left tweety
out of the example, because the relationship is member-of rather than
subset-of.
1. [Ax.ancestor(class)(x) -> p(x)] & ~ab aspectn(class,p) ->
[Ax.class(x) -> p(x)]
2. [Ax.ancestor(class)(x) -> p(x)] & ab aspectn(class,p) ->
[Ax.class(x) -> ~p(x)]
3. [Ax.ancestor(class)(x) -> ~p(x)] & ~ab aspectn(class,p) ->
[Ax.class(x) -> ~p(x)]
4. [Ax.ancestor(class)(x) -> ~p(x)] & ab aspectn(class,p) ->
[Ax.class(x) -> p(x)]
An example:
This relation expresses the hierarchy.
ancestor(animal) = thing
ancestor(bird) = animal
ancestor(canary) = bird
ancestor(ostrich) = bird
ancestor(penguin) = bird
The default is that things don't fly.
[Ax.thing(x) -> ~flies(x)]
These things are different than their immediate predecessors in the hierarchy
ab aspectn(bird,flies)
ab aspectn(ostrich,flies)
ab aspectn(penguin,flies)
Using rule 3,
[Ax.ancestor(animal)(x) -> ~flies(x)] & ~ab aspectn(animal,flies) ->
[Ax.animal(x) -> ~flies(x)]
[Ax.thing(x) -> ~flies(x)] & ~ab aspectn(animal,flies) ->
[Ax.animal(x) -> ~flies(x)]
One of our assumptions is that the first part of the antecedent is
true. By circumscription of abnormality we find the second part of
the antecedent also true, making the consequent true. Thus we can
conclude
[Ax.animal(x) -> ~flies(x)]
Using rule 4,
[Ax.ancestor(bird)(x) -> ~flies(x)] & ab aspectn(bird,flies) ->
[Ax.bird(x) -> flies(x)]
[Ax.animal(x) -> ~flies(x)] & ab aspectn(bird,flies) ->
[Ax.bird(x) -> flies(x)]
By the previous conclusion and our known abnormality of birds and
flying in aspect n, we have
[Ax.bird(x) -> flies(x)]
Using rule 1,
[Ax.ancestor(canary)(x) -> flies(x)] & ~ab aspectn(bird,flies) ->
[Ax.canary(x) -> flies(x)]
[Ax.bird(x) -> flies(x)] & ~ab aspectn(canary,flies) ->
[Ax.canary(x) -> flies(x)]
We conclude that all canaries can fly.
Using rule 2,
[Ax.ancestor(penguin)(x) -> flies(x)] & ab aspectn(penguin,flies) ->
[Ax.penguin(x) -> ~flies(x)]
[Ax.bird(x) -> flies(x)] & ab aspectn(penguin,flies) ->
[Ax.penguin(x) -> ~flies(x)]
Thus, no penguins can fly.
-------
pack@score
is-a
I haven't checked whether your proposed is-a formalization suffers
from the same problem as your bird formalization. However, it
doesn't meet my goal in another way, and that is your use of an
ancestor function; if it were an ancestor relation, that would be
ok, but you use it as a parent function. For example, you write
ancestor(bird) = animal, but you might have written
ancestor(bird) = vertebrate and ancestor(vertebrate) = animal.
Our human inheritance algorithm, whatever it may be, does not
require a fixed parentage chain. It can deal with the situation
in which there are an unknown or even undefined number of intermediates
between bird and animal. This is the goal I tried to state.
Returning briefly to your first message, let me state the goal that
axiom systems should be devised so that circumscribing ab gives
a definite result in those cases where our informal reasoning would
give a definite result.
Please persist in your efforts to formulate axioms. A few more tries
and you'll get some I won't be able to find flaws in. At least they
won't be the same flaws that I found in some of my own previous efforts.
If there is anything unclear about these comments, I'll be glad to discuss
them either in person or by phone. My home phone is 857-0672, and I'm usually
free to talk except at dinner time.

Subject: another try
To: jmc@SU-AI.ARPA
Here is another try at making the is-a hierarchy more general. I'm
not yet sure if the circumscription works, but the axioms have a
similar form to the ones that you use for the specific bird example.
I'll come and talk at 4:30 on Thursday.
Rules for expressing a general is-a hierarchy.
If there is some ancestor of the class we are concerned which for
which the property holds for all memebers, and the ancestor, current
class and property are not abnormal in aspect1 then the property holds
for all members of the current class.
1. [Ec.is-ancestor(c,class) & [Ax.c(x) -> p(x)] & ~ab aspect1(c,class,p)] ->
[Ax.class(x) -> p(x)]
The same as axiom 1, only expressing the inheritance of negative properties.
2. [Ec.is-ancestor(c,class) & [Ax.c(x) -> ~p(x)] & ~ab aspect1(c,class,p)] ->
[Ax.class(x) -> ~p(x)]
If there is an odd number of descendents of the first class who are
ancestors of or equal to the second class which are abnormal with
relation to the predicate we are considering, then the truth of the
predicate is not inherited.
3. [Es.[Ac.[is-ancestor(class1,c) &
[is-ancestor(c,class2) v equal(c,class2)] &
ab aspect2(c,p)] <->
member(c,s)] &
odd (cardinality (s))] ->
ab aspect1(class1,class2,p)
Restated in ppc -- a little easier to see the structure
2. (if (exist s (and (all c (if-only-if (and (is-ancestor class1 c)
(or (is-ancestor c class2)
(equal c class2))
(ab (aspect2 c p)))
(member c s)))
(odd (cardinality y))))
(ab (aspect2 class1 class2 p)))
Now we need to say something positive about such classes...
If there is an odd number of intervening abnormalities and the ancestor
class has the property then the descendent class does not have the property.
3. (if (and (exist s (and (all c (if-only-if (and (is-ancestor class1 c)
(or (is-ancestor c class2)
(equal c class2))
(ab (aspect2 c p)))
(member c s)))
(odd (cardinality y))))
(not (ab (aspect3 class1 class2 p)))
(all x (if (class1 x)
(p x))))
(all x (if (class2 x)
(not (p x)))))
Negative version
4. (if (and (exist s (and (all c (if-only-if (and (is-ancestor class1 c)
(or (is-ancestor c class2)
(equal c class2))
(ab (aspect2 c p)))
(member c s)))
(odd (cardinality y))))
(not (ab (aspect3 class1 class2 p)))
(all x (if (class1 x)
(not (p x)))))
(all x (if (class2 x)
(p x))))
An example:
This relation expresses the hierarchy.
is-ancestor(thing,animal)
is-ancestor(thing,bird)
is-ancestor(thing,penguin)
is-ancestor(thing,canary)
is-ancestor(thing,dog)
is-ancestor(animal,penguin)
is-ancestor(animal,dog)
is-ancestor(animal,canary)
is-ancestor(bird,canary)
is-ancestor(bird,penguin)
The default is that things don't fly.
[Ax.thing(x) -> ~flies(x)]
These things are different than their immediate predecessors in the hierarchy
ab aspect2(bird,flies)
ab aspect2(ostrich,flies)
ab aspect2(penguin,flies)
Using rule 2,
[Ec.is-ancestor(c,animal) & [Ax.c(x) -> ~flies(x)] &
~ab aspect1(c,animal,flies)] ->
[Ax.animal(x) -> ~flies(x)]
Instantiate c to thing
is-ancestor(thing,animal) & [Ax.thing(x) -> ~flies(x)] &
~ab aspect1(thing,animal,flies) ->
[Ax.animal(x) -> ~flies(x)]
All that we need to show is ~ab aspect1(thing,animal,flies). We shall
assume it is not abnormal unless we can prove that it is using axiom 3.
[Es.[Ac.[is-ancestor(thing,c) &
[is-ancestor(c,animal v equal(c,animal)] &
ab aspect2(c,p)] <->
member(c,s)] &
odd(cardinality(s)) ->
ab aspect1(thing,animal,flies).
We have no classes satisfying the requirements for membership in s, so
its cardinality is 0 which is not odd. Since we cannot prove its
abnormality, we conclude ~ ab aspect1(thing,animal,flies), which
allows us to conclude our goal, Ax.(animal(x) -> ~flies(x)).
Now, let us see if birds can fly...
Using rule 1 as before we can easily arrive at the following:
~ab aspect1(thing,bird,flies) -> [Ax.bird(x) -> ~flies(x)]
In this case, however, we find s in axiom three equal to {bird}. The
cardinality of s is odd, and so we conclude ab aspect1(thing,bird,flies).
Rule 2 cannot tell us anything about the flight of birds, so we try
rule 4. Its antecedents are all satisfied because we assume the normality
of aspect3 in absence of information about it. Thus, we can conclude
[Ax.bird(x) -> flies(x)].
In trying to prove whether or not penguins can fly, we try rule 2. It
is easily reduced to
~ab aspect1(thing,penguin,flies) -> [Ax.penguin(x) -> ~flies(x)].
In using rule 3 to try to disprove the antecedent, we find the set
e equal to {bird,penguin}. Its cardinality is even, so we have failed
to prove ab aspect1(thing,penguin,flies). We can conclude
[Ax.pengiun(x) -> ~flies(x)].
We might have approached this problem differently. If we had our
result from the previous example ([Ax.bird(x) -> flies(x)]) we might
have reduced our problem to
~ab aspect1(bird,penguin,flies) -> [Ax.penguin(x) -> flies(x)].
Since, however, our set e in axiom 3 is {penguin}, this will fail and we
have to use axiom 4 to conlude that penguins cannot fly.

The Diablo mailer at Stanford was extremely flaky last week. As a
result, a number of people didn't get the announcement of this Friday's
knowledge seminar, while others got many copies of bad messages. I
am sending out the announcement again, in the hopes that it will
work better this time, and come in time to be of use.
The knowledge seminar will be continuing as scheduled on Feb. 24,
at 10 AM. Our speakers will be Kurt Konolige of SRI and Yoram Moses
of Stanford. The abstracts are included below. Our speaker for
March 9 will be Bob Moore of SRI and Hector Levesque of Fairchild.
See you then.
A Deduction Model of Belief -- Kurt Konolige
Most current formal models of belief for AI planning systems are
derivatives of a possible-world semantics for belief. However, this
model suffers from epistemological and heuristic inadequacies.
Epistemologically, it assumes that agents know all the consequences of
their belief. This assumption is clearly inaccurate, because it
doesn't take into account resource limitations on an agent's reasoning
ability. For example, if an agent knows the rules of chess, it then
follows in the possible-world model that he knows whether white has a
winning strategy or not. On the heuristic side, proposed mechanical
deduction procedures have been first-order axiomatizations of the
possible-world semantics, an indirect and inefficient method of
reasoning about belief.
A more natural model of belief is a deduction model: an agent has a
set of initial beliefs about the world in some internal language, and
a deduction process for deriving some (but not necessarily all)
logical consequences of these beliefs. Within this model, it is
possible to account for resource limitations of an agent's deduction
process; for example, one can model a situation in which an agent
knows the rules of chess but does not have the computational resources
to search the complete game tree before making a move.
This talk will be about the deduction model of belief and its
formalization by modal logic families. I will discuss some of the
following issues:
1. the correspondence between the deduction and possible
world model;
2. a theory of ignorance;
3. a theory of introspection.
A formalization of the Wise Man Puzzle and a derivative, the
not-so-wise-man problem, will also be given.
Knowledge and Common Knowledge In Distributed Systems -- Yoram Moses
The notion of knowledge in a distributed environment is fundamental to many
issues in distributed computing. Many tasks in a distributed system
directly involve the achievement of specific states of knowledge and others
crucially depend on a variety of constraints on the state of knowledge of
the parties involved. Communication in a distributed system can be viewed
(and in some cases should be viewed) as the act of transforming the system's
state of knowledge. Of particular importance is the notion of Common Knowledge,
which can be viewed as the generalization of an individual's knowledge to a
group. Common knowledge is inherent in notions such as agreement.
We investigate the conditions needed to achieve common knowledge of a fact in a
distributed system, showing that there are practical problems in achieving it
in actual systems. We present a new related notion, called epsilon common
knowledge that corresponds to the knowledge state achievable in some reasonable
systems. We show how this notion can be incorporated into a logic of knowledge,
and compare it with common knowledge. We discuss the logical and practical
implications of this to actual knowledge and action in distributed environmemts.
This work is joint with Joe Halpern of IBM San Jose.

it might be that indeed you worked with lambda notation before lisp deve-
lopment started.j.slagle gave me very short notice he had done watching
a lecture of you in may 58.there lambda notation is mentioned in connec-
tion to function composition.
you wrote a paper "notes on the sky-blue compiler.on functions which pro-
duce more than one quantity as output" in 1957 (7/11/).the titel looks
quite similar to some ideas in the algol-connected paper of 1958.do you
have a saved copy?
what would you think were the reasons for Morse to send you in the ALGOL
group (better:ACM ad hoc committee)? as far as i know you had no published
paper at this time which proved you as programming language specialist.
There was no such thing as a programming language specialist, and I
was the faculty member with the most programming language interests,
although one of the programmers had worked in the Fortran group at
IBM. I believe I was already making propaganda for the idea of
an algebraic list processing language.

Hi John,
The discussion session I invited you to be guest for is Thursday,
March 15, 9:30-11:30am, in MJ 352. CS229b is a course oriented to qual
preparation. It consists of reading, student-only discussion sessions on
Tuesdays (9:30-12), and discussions with a guest on Thursdays (9:30-11:30).
The course is organized around one topic per week. Our last week is,
however, miscellaneous, which we have decided to devote to issues of:
supercomputer architecture for AI
programming languages for AI
evaluating AI systems
The class has expressed desire to have you be our guest to discuss these and
your general thoughts on AI.
Our format with guest discussions is informal, basically question-and-answer.
Please feel no responsibility to prepare anything. If you'd like to make
some opening remarks for say half an hour, that's fine.
Please let me know if you'll be able to come, as soon as you can.
----------------------
I really enjoyed getting the opportunity to talk with you at length this
afternoon. I'm quite busy these days what with qual, probabilities, and
programming project, but I will keep thinking about circumscription and
nonmonotonicity.

that he didn't, and it may even be that the letter to Morse was

John,
Our current arrangements are substantially the same as in other years';
however, the registration is now off campus, which is a compromise from
our original plan. There are some real advantages with having the
registration off campus, i.e. we can now sell extra proceedings, memberships,
and magazines whereas at the university, it would have been a problem.
Also, with the revised building use agreement (which eliminated the
sections on the return of excess funds to UT and extra fee charges),
our only financial responsibilities to UT is the payment of direct
services (ie electricians, guards) which was anticipated.
That's it for now.

TOPIC: Learning and Problem Solving
ABSTRACT:
One mark of intelligence is the ability to improve one's
problem-solving abilities through experience. Modelling this kind of
learning is an important goal for AI, both because it is bound to lead
to general insights on the nature of intelligence, and because of its
practical importance for developing high-performance problem solving
programs. We discuss some recent progress in the area of learning
problem-solving expertise, as well as some directions in which
research in this area is headed.

We have received a preliminary umbrella contract in the amount of
$12,482,047. This is $997,50l short of the umbrella proposal. These
figures include indirect costs.
The tasks for all six of you total $6,969,821. The major cut is in
the salaries proposed; the cut is a combination of position elimination
and a reduction from 8% to 6% in salary increases over the three years.
You will recall that we included positions and expenses to allow for
additional tasks over the three year period. The question now is whether
the $5,512,226 (including indirect costs) will be sufficient to add tasks
over the three years.
Another question to be resolved is how the $697,000 addition to the current
contract fits into the picture, i.e., whether it is to be deducted from
the $12,482,047 proposed award on the new contract. I am trying to confirm
exactly how this is to be handled, and will let you know as soon as I have
the answer.
I do not know whether specific tasks have been cut in the overall award
reduction, since we only have the "lump" sum figure. I am working with SPO
now to try and get this additional detail.
I will appreciate your comments on the information I have to date, and I
will certainly keep you informed of any new information received.
Please keep in mind that we don't have an effective contract date; this won't
be assigned until the contract has been approved both by Stanford and by
Navelex.

Received: from SUMEX-AIM by SU-AI with TCP/SMTP; 27 Feb 84 11:58:42 PST
Date: Mon 27 Feb 84 11:58:08-PST
From: Samuel Holtzman <HOLTZMAN@SUMEX-AIM.ARPA>
Subject: MEU
To: jmc@SU-AI.ARPA
cc: holtZMAN@SUMEX-AIM.ARPA
Dear Professor McCarthy:
Thanks for your comments on "ought" rules. Your opinion is very useful
to me since your perspective is different from that of most of my
colleagues. In particular your argument against a unitary ought rule
has made me rethink my position regarding Maximum Expected Utility
(MEU).
I certainly do not claim that MEU is a good descriptor of human
behavior except, perhaps, in trivial situations. In contrast, I feel
that the normative power of the rule is remarkable. The context in
which I mean this, however, requires some explanation. I will address
mostly the use of MEU for prescribing human action.
The problem that interests me is the situation encountered by people
who are faced with a decision for which they have no strong
heuristics. That is, when people are "stuck" with a decision. Two
brute-force approaches to this problem are a) to provide a
recommendation for action by solving a decision theoretic
representation of their problem and b) to give them access to an
expert system which can increase their domain knowledge in hopes of
promoting the development of the needed heuristics. However,
paraphrasing Herb Simon, people do not commit valuable resources
solely as a consequence of a logical argument, regardless of its
correctness. To really help people who are stuck with a decision
problem we must give them insight.
If our purpose is to develop insight, rather than to compute answers,
it is very useful to have a formal method in which to describe
assumptions and infer their consequences. MEU works wonders in this
context. Note that I am not saying that this, or any other rule is
what people should obey to make "good" decisions. What I am claiming
is that the EFFORT needed to formalize a problem can often get people
UNSTUCK (I have seen this happen repeatedly when I wear my consultant
hat). MEU's desirability does not come from its uniqueness -- it is
certainly not a panacea -- but from the fact that it is the best
formalization of decision making behavior I know of (Savage and
DeFinetti did a pretty good convincing job). It is important to
realize that I am not even basing my argument on the success of the
effort to formalize a decision problem; all that is required is that
the decision maker give it a good try. It is interesting to note in
this context that a good indicator of a successful decision analysis
is the fact that no final report is written: no one needs to be
convinced of what should be done!
Let me now address you specific comments regarding prescriptive rules.
In your note you made two crucial points:
1. "We can only formulate rules governing small (in some
sense) models of certain aspects of the world."
2. "Suppose that we have a certain parametrized set of
circumstances, and suppose that the prescriptions of the set
of rules are unambiguous and intuitively satisfactory in these
circumstances. Suppose now that we propose to expand the
collection of circumstances considered. It may happen that
the rules become ambiguous or that the results are intuitively
unsatisfactory. Is there necessarily a more comprehensive
rule that will give even approximately the same results in the
limited circumstances, which can be compactly formulated and
which is intuitively satisfactory. My opinion is that this is
not guaranteed."
I fully agree with both points, and not just in terms of MEU, but for
any formal decision making method. In my dissertation I claim that
for a formal method to be valid in the context of a given real
situation, it must meet two conditions that are closely related to
your two points: local correctness, and structural regularity. The
former condition implies that the formal method should give
intuitively correct answers "in the small," the latter is a requirement
that the domain be such that the normative method remains applicable
as problems within it increase in size and complexity. I claim that
MEU is locally correct, and that the domain of personal decision
making is structurally regular with respect to the MEU axiom.
A final advantage of a unique action axiom: simplicity. Although I
recognize the possibility that a multiple "ought" rule systems might
provide attractive alternatives to MEU (I am aware of very good work
in this direction), there is certain beauty in a single-axiom
formalization. In particular, there is no need for an arbiter -- a
possibly messy issue.
One last comment regarding the use of MEU for automated decision
making: I DO NOT THINK THAT AUTOMATED DECISION MAKING IS A GOOD IDEA
unless a) the resources involved are small (e.g., automatic
manufacturing, file manipulation), or b) there is an explicit
advantage to delegating authority (e.g., deep space probes,
quick-response real time systems). Neither case concerns me very
much; heuristic systems may well be an efficient solution. In
general, however, I worry. As you are well aware, the use of
automatic decision systems in contexts such as defense, and medicine
is very possible in the foreseeable future. One advantage of MEU is
that it makes the surrogate decision maker's VALUES very EXPLICIT.
Multiple ought-rule systems are likely not to share this feature. The
last thing I want to see is an automated politician with a direct
means to remove my kidneys, or explode a bomb.
Again, let me thank you for your comments. They have been very
helpful to me in clarifying my ideas.
Regards,
Sam Holtzman

There are some problems using the APEX fare.
1. You had to stay one more day to qualify, which means returning
Sunday, April 1.
2. There were no APEX seats available on 4/1 from Orly to JFK,
so I used the London routing. Fare is still $999 RT.
3. Ticketing deadline is Mar. 3, which is a Saturday, so you may want
to get them done Friday, Mar. 2. Cancellation or changes after
ticketing bring a $50 penalty, plus you would not qualify for the
fare. Coach fare is $1878 RT.
4. These reservations were made directly with Pan Am, 364-1921.

I do not want to get into a big flame war about IBM vs DEC but your
message included some misstatements that I think ought to be corrected:
(1) the line editor may be rubbish, but the full screen editor is
very well done. Massive features dumped in an unsystematic way onto
a poorly designed base do not a super editor make, and tailorability
that requires one to be a wizard does not 'a powerful, extensible'
editor make.
(2) EXECs are not only described fully in the basic user's manual, but
one does not have to be an expert to use them. They also have the
advantage of being usable to control edits and full-screen management
easily. While there are indeed problems w/ VM and CMS, EXECs are the
one thing that other manufacturers would do well to copy. Not being
able to easily tailor one's work environment is what makes other
systems so horrendous.

"Quantitative System Performance: Computer System
Analysis Using Queueing Network Models" by Edward
D. Lazowska, John Zahorjan, G. Scott Graham, and
Kenneth C. Sevcik, Prentice-Hall, 1984.
Catalog Description
-------------------
The use of queueing network performance models as
tools in the design and analysis of computer systems.
Topics include Little's law and other fundamental
relations, bounding the performance of systems,
algorithms for evaluating queueing network models,
flow equivalence and hierarchical modelling, detailed
representation of specific subsystems, parameterization
of models, the structure and use of queueing network
modelling software. Various exercises, one examination,
and a realistic case study.
Course Schedule
---------------
Two 1.5-hour meetings per week, at either the beginning
or the end of the day. Fall Q, so that Sevcik can
participate; there's a good chance he'll be in Europe
during Winter and Spring Q.
Support Requirements
--------------------
Ideally, two computing facilities. The first would be
a 370 running VM/370. (That's what commercial-grade
queueing network modelling software runs on; sorry.)
The second would be a more hospitable environment
for student exercises, done in Pascal or some similar
language.

SEMANTICAL CONSIDERATIONS ON NONMONOTONIC LOGIC-- Bob Moore, SRI
Commonsense reasoning is "nonmonotonic" in the sense that we often
draw, on the basis of partial information, conclusions that we later
retract when we are given more complete information. Some of the most
interesting products of recent attempts to formalize nonmonotonic
reasoning are the nonmonotonic logics of McDermott and Doyle
(McDermott and Doyle, 1980; McDermott, 1982). These logics, however,
all have peculiarities that suggest they do not quite succeed in
capturing the intuitions that prompted their development. In this
talk we reconstruct nonmonotonic logic as a model of an ideally
rational agent's reasoning about his own beliefs. For the resulting
system, called "autoepistemic logic," we define an intuitively based
semantics for which we can show autoepistemic logic to be both sound
and complete. We then compare autoepistemic logic with the approach
of McDermott and Doyle, showing how it avoids the peculiarities of
their nonmonotonic logic.
-------
A Logic of Knowledge and Active Belief-- Hector J. Levesque, Fairchild Labs
As part of an on-going project to understand the foundations of Knowledge
Representation, we are attempting to characterize a sense of knowledge
that forms a more appropriate basis for Knowledge Representation systems
than that captured by the usual possible-world formalizations (begun by
Hintikka). In this talk, we will point out deficiencies in the current
semantic treatment of knowlege including the recent syntactic approaches
and suggest a new analysis (in the form of a logic of knowledge and
belief) that avoids some of these difficulties.

Idont think we ought to take a casual view of crosslisting, since it may confuse
students, confuse transcrpits, and confuse the outside world. I think we ought
to see the course descriptions and/or outlines before agreeing. The Psych187
might be OK, the other two may not be very reasonable.

performed. This is the technique by which placques in blood
vessals (coronary arteries in my case) are compressed by inflating
a balloon. They will be using a rather new catheter which allegedly
can get the balloon into tight spaces and around corners in a way
not previously possible. Angioplasty is done under sedation, but there
is no anaesthesia needed, and if all goes as expected, I'll

SIGLUNCH
Friday, March 9, 1984
LOCATION: Braun Lecture Hall (smaller), ground floor of Seeley Mudd
Chemistry Building (approx. 30 yards west of Gazebo)
12:05
SPEAKER: Ben Grosof
Stanford University, HPP
TOPIC: AN INEQUALITY PARADIGM FOR PROBABILISTIC KNOWLEDGE
Issues in Reasoning with Probabilistic Statements
ABSTRACT:
BACKGROUND: Reasoning with probabilistic knowledge and evidence is
a key aspect of many AI systems. MYCIN and PROSPECTOR were pioneer
efforts but were limited and unsatisfactory in several ways. Recent
methods address many problems. The Maximum Entropy principle
(sometimes called Least Information) provides a new approach to
probabilities. The Dempster-Shafer theory of evidence provides a new
approach to confirmation and disconfirmation.
THE TALK: We begin by relating probabilistic statements to logic. We
then review the motivations and shortcomings of the MYCIN and
PROSPECTOR approaches. Maximum Entropy and Dempster-Shafer are
presented, and recent work using them is surveyed. (This is your big
chance to get up to date!) We generalize both to a paradigm of
inequality constraints on probabilities. This paradigm unifies the
heretofore divergent representations of probability and evidential
confirmation in a formally satisfactory way. Least commitment is
natural. The interval representation for probabilities includes in
effect a meta-level which allows explicit treatment of ignorance and
partial information, confidence and precision, and (in)dependence
assumptions. Using bounds facilitates reasoning ABOUT probabilities
and evidence. We extend the Dempster-Shafer theory significantly and
make an argument for its potential, both representationally and
computationally. Finally we list some open problems in reasoning with
probabilities.

Subject: A major change in prospect
To: Friends-and-Colleagues: ;
Dear Friends and Colleagues,
The time has finally come for me to join the migrating throng and seek
my fortune in the great wide world. After 13 years at SRI International,
deciding to leave it has not been an easy choice; I will miss a remarkable
institution, wonderful people, a distinctive life style, and a set of
memories that will always stay with me.
Needless to say, the call that would provoke such an action must be
something special, and indeed it is. Bell Communications Research, an
organization newly formed by the seven telephone operating companies to be
their very own "Bell Labs," has asked me to head a group devoted to
'Artificial Intelligence and Information Science Research.' This position
will provide me with a unique opportunity to pursue the goals embodied in
the 'Natural-Language and Knowledge-Resource Systems Program' that I
recently established at SRI.
I will begin working on a part-time basis for Bell Communications
Research late this month, although the separation from SRI and the
transition from Menlo Park and Palo Alto to Morristown, New Jersey, will not
be complete until late in July. During this interim period, I will be
spending most of my time on the West Coast, so general communications should
continue to be directed to SRI. The COLING84 conference, which will be held
2-6 July at Stanford, marks the turning point. I deeply appreciate the
support and cooperation being provided by both SRI and Bell Communications
Research in facilitating this unusual change of state.
My involvements with the Association for Computational Linguistics and
the International Joint Conferences on Artificial Intelligence will continue
from my new location, as will my now less active participation in the
American Association for Artificial Intelligence. I look forward to further
personal and professional interactions with you all.
Respectfully,
Don

Some confusion had arisen about at least the Expert Systems Technology
sources sought announcement that appeared in the Commerce Business Daily
on Feb. 21. Many of us had been going on a prerelease version of the
announcement that did not contain all of the information in the actual
published version. In particular, DARPA wants >>BOTH<< a 5-page
qualification statement and a 15-page proposal by March 22! They plan to
convene a review group on March 27-29 to decide on actual awards using FY84
money. They want to start some of the contracts by July. Therefore, we
must get our various proposals for this program together fast!

I've been thinking that the AAAI should honor Don Walker during the

organization during its early days, and he regularly offers support
on official matters of the AAAI. I thought we could give him a

them? Raj?

There is not much that E can explain in the small space at the bottom of

various possibilities for saving the text, such as: attaching it and
moving it to a new window, attaching it and switching to another (possibly
the same, but formatted) file, mailing it to yourself, or saying ⊗xSave to
have E save all incore text in an emergency file. I suppose I could mention
one of these in the brief message about unformatted files (etc.). However,
you're supposed to get that message as soon as you start editing a page
in such a file, and then again anytime you try to write it out. Formatting
a file is offered automatically if you try to edit a file NOT in /R mode.
One page files are always "formatted" (/N), so you can just say ⊗xReadWrite.
Probably that's what you did before adding a pagemark and making it two
pages. Then you probably went back to the file /R, at which point it is
really unformatted as far as E knows. Saying ⊗xReadWrite at such a point
will report that you can't do that, as will trying to change any text.

Brian,
I don't agree with your proposal because it erodes a traditional
prerogative of a faculty member (and as I mentioned in my last note on
this, a tradition that goes back all the way to the founding of
the modern university). In that sense, I am a "conservative". If we want
not to conserve this tradition, let's change it with full discussion
sometime in a faculty meeting.
In general, the evaluation of candidates is a subjective affair (although
we strive each year to make it otherwise). In particular, as you said at
a meeting earlier this year, once we're down to the last eighty, the
random draw would yield as "good" a set as any other. The most
important "qualification" a candidate can have is that a faculty member
wants her/him. Certainly this can be abused, but as JMc pointed out,
limiting this to one (per faculty member) limits the possibility of
abuse to the level of the negligible.
There is no "greater good" in your striving for the "best" set of
admittees (indeed there is no "best" set that we know how to determine).
There is only the sum of the "individual goods". The faculty IS the
department, and I propose that we continue this "individual good"
or if we must change it, then only with considerable discussion by
the faculty.
To be concrete, what this means is that "whiteballed" applicants (to use
your term) should receive "yes" letters (but limited to one per faculty
member).
With best wishes,
Ed

If you anticipate any more trips that will have to

Betty is very concerned that they will disallow the

cannot be considered "necessary to continue the research,"
and we have no funds specifically allotted to travel left.
She wants to try to get approval for it from Rob Simpson

I doubt they can pay for all because they have $2k for all travel to this

From: Ken Laws <Laws@SRI-AI.ARPA>
Subject: Beliefs of Thermostats
To: JMC@SU-AI.ARPA
cc: laws@SRI-AI.ARPA
I have no general difficulty in ascribing beliefs to mechanism.
In the particular case of thermostats, however, I have some
reservations.
Although we could ascribe beliefs to rocks, it would seem to
violate an aesthetic principle of economy. Likewise, it seems
unreasonable to ascribe to thermostats any beliefs about humans
in its sphere of influence and the effects of temperature on
their comfort. The behavior of a simple thermostat can be
explained (or predicted) just as well without imagining that
the thermostat has any such mental baggage.
The minimal belief set, assuming that we ascribe beliefs at all,
appears to be on the order of the thermostat believing that the
room is too warm or, equivalently, believing that its switch
should be open at this time. It believes these things because
of its physical structure and organization.
The first statement, though, implies that the thermostat has
some notion of its environment, at least to the level of ambient
temperature, and some notion of the temporal effects on that
environment of the action(s) that it can take at the current time.
The second statement is just as bad since the word "should"
introduces either normative/ethical concepts or some awareness
of possible worlds.
I would find such attributions palatable in more complex mechanisms,
but surely the beliefs of a thermostat should be limited to the
>>here<< and >>now<< if its behavior can possibly be explained
by such means. Its beliefs and reasoning should be of the form
"I am too warm, therefore my switch is open."
This, of course, is such a primitive level of belief that it fails
to provide the naive mental model of thermal homeostasis that you
were seeking when you began the inquiry into beliefs of machines.
The concept of negative feedback must now be supplied by the person
thinking about the thermostat, or at best is only implicit rather
than explicit in the thermostat's belief set. A pity, but if you
are looking for the smallest meaningful "unit of belief", I think
this is it. Attributing more powerful beliefs to the thermostat
is a useful heuristic, but is not fully justified and will no doubt
raise the hackles of philosophers.

beliefs of thermostats
Thanks for your message. I have two comments.
1. First, you missed a transition that arose in the discussion. Ascribing
beliefs about what temperatures made what humans comfortable was in
connection with a hypothetical more elaborate temperature control
mechanism that was designed to take such facts into account. For
the very simplest thermostat, I proposed only the beliefs, "the room is
too cold", "the room is too hot", and "the room is ok".
Perhaps I made the transition without adequate notice.
2. Second, there is the question of whether the thermostat believing
"the room is too cold" requires that the thermostat know how sentences
are constructed from parts, i.e. that it somehow generate or understand
the sentence. I don't want to assume any such thing. "The room is
too cold" is how we express the belief. Ascribing the belief is
supported by the fact that the thermostat does what will achieve
the goal we also ascribe to it, i.e. making the temperature ok.
Also, please remove me as a subscriber to the AI list digest, since
I'll change to reading the public copy.

If you re-read my note, I am not saying that the admissions committee

current round of "put this person in round II please" computer mail
notes to be whiteballs.
If you want to have a person admitted, give us a note to that effect,
in writing, on a piece of paper, which we can put into that person's
permanent application file, and we will admit him. My previous note
said this same thing but in contrapositive--if you don't do this we
won't admit him.

In-Reply-To: Message from "John McCarthy <JMC@SU-AI.ARPA>" of Sat 10 Mar 84 00:04:00-PST
I'll make the change in the AIList distribution.
I was aware of the transition between simple and elaborate thermostats,
and was only commenting on the simple ones in my message. My point was
that, for the simple thermostat, we would not want to say "It believes
that I am too warm, and therefore it will shut off the heat." We can
build a simpler mental model of the thermostat's action based on ambient
temperature; the concepts of humans and human comfort are unnecessary
and thus inelegant. This appears to be in accord with your own theory of
thermostat beliefs and scientific parsimony, and establishes a common
ground for further reasoning. I'm sorry that I didn't make it clear that
I was in complete agreement with you.
I then diverged from your line of reasoning as expressed at the talk and
in your reply to me. I am concerned that you ascribe to the thermostat
not only beliefs about its current state, but also goals or knowledge of
the potential effects of its actions. I have no objection to the
thermostat knowing (or believing) its current state, and I am only a
little uneasy at the idea that it knows what states it could be in were
its environment different. I object, however, to the idea that it
believes it can change its environment through its own actions. >>We<<
know that the thermostat's purpose is to control the environment, but
the thermostat's belief should be that the environment controls it. If
you want to talk about the entity that does believe it can control its
environment, you should be talking about the heating system as a whole
rather than just the thermostat.
In part, my position is a reaction to your statement that a rock is the
zero of belief and a thermostat is the unit measure of belief. I accept
this with my restricted view of a thermostat, but not with your more
liberal view. I agree, though, that your view is more in line with the
way that people normally reason (when rigor is not demanded), and that
it is a more powerful view for making high-level statements.
Thanks for listening.

Dear John,
Etherington's proof seems to have a fatal flaw.
Here is my simple proof that circumscribing the equality predicate in a theory
T(=) yields nothing new, i.e. that
T(=) proves Circumscription schema for =
Assume T(=) contains the usual axioms for equality, in particular (x)x=x, and
axioms sanctioning the substitution of equal terms for each other.
We want to show
T(=) proves [T(phi) & [(xy)phi(x,y) --> x=y]] --> [(xy)x=y --> phi(x,y)]
i.e. show
T(=), T(phi), [(xy)phi(x,y) --> x=y], a=b proves phi(a,b)
Now T(=) contains (x)x=x, so T(phi) contains (x)phi(x,x)
So with (x)phi(x,x), a=b and the principle of substitution we can prove
phi(a,b). QED
I also think that circumscription may have other limitations. For example,
intuitively, circumscribing P in (Ex)P(x) should yield (E!x)P(x). I have
tried very hard to get this but can't. Do you know how?
Best wishes, Ray.

Steve, You should be receiving a source qualification statement via Federal
Express this morning in response to your Multiprocessor Computer
Architecture Project announcement in the CBD. It is under Ed Feigenbaum
as PI and involves a close collaboration between members of the Stanford
Heuristic Programming Project, John McCarthy and Dick Gabriel from the
Stanford Formal Reasoning Project, and Bruce Delagi from DEC.
Rather than just working on multiprocessor hardware designs and seeing what
symbolic computing problems they are useful for, we propose to work on
integrated software and hardware architectures for concurrent symbolic
computing in knowledge-based systems. This work will be driven by
applications involving signal understanding and will investigate concurrency
derived from the application domain, the organization and use of knowledge
and problem solving strategies, the implementation languages and system
software, and the underlying computing hardware.
We recognize that with this vertical cut, from application through
underlying hardware, there is a strong intersection of this proposed work
with other parts of the Strategic Computing Program. We are also preparing
a related submission for consideration under Ron Ohlander's Expert Systems
Project later this month.
Please let us know if you need additional information. Tom R.

John,
Can you please review this draft about local chapters before I send
it out to the Execomm?
Thanks,
Claudia
Dear Colleague:
During the last twelve months, AAAI officers have received several
requests to establish local AAAI chapters in the Pacific Northwest,
Washington, D.C., Boston, and Florida.
As a means of satisfying this emerging need, we propose to help
establish local chapters informally by providing to the local contacts
the members' names and addresses in a particular region. It would
then be the responsibility of that person to reach local people and to
establish meeting schedules and activities. They could also collect
dues to cover direct costs (e.g. phones, room rental). At the same
time, we will need to establish some safeguards so that local contacts
do not abuse the lists of members we provide to them.
We would like to hear your comments on the establishment of local
chapters so that we can respond to these requests.

Claudia,
The draft on local chapters is ok. I suggest you send it out
over both our names. In general, I think that nothing bad is likely
to happen, and if something does, we can correct it, since chapter
charters should be revokable.

LOCATION: Chemistry Gazebo, between Physical & Organic Chemistry
TIME: 12:05
SPEAKER: Bill Swartout
USC/Information Sciences Institute
TOPIC: Explainable Expert Systems
ABSTRACT:
Traditional methods for explaining expert systems provide explanations
by converting the code of the program to English. While such methods
can sometimes adequately explain program behavior, they cannot justify
it. That is, such systems cannot explain why what the system is doing
is reasonable. The problem is that production of justifications
requires knowledge of how the expert system itself was created, but
that knowledge is not recorded as part of the code and hence is
unavailable. This talk will first describe the XPLAIN system, a
previous research effort which used an automatic programmer to capture
the development of an expert system from abstract domain knowledge,
thereby providing the knowledge needed to improve its explanatory
capabilities. We will then outline the goals and research directions
for the Explainable Expert Systems project, a new research effort just
starting up at ISI.
Our current research focuses on three areas. First, we want to extend
the XPLAIN framework to represent additional kinds of knowledge such
as control knowledge for efficient execution. Second, we want to
investigate the generation of systems that can reason either with
abstract knowledge and general methods or highly specific
assumption-based procedures while maintaining a representation of the
relationship between the two forms of knowledge. A system that could
use either abstract or specific methods could be both robust and
efficient -- using its specific knowledge with built-in assumptions
for simple cases but reverting to deeper knowledge for complex cases.
Third, we will use the richer framework provided by the XPLAIN
paradigm to allow the system to form appropriate abstractions when new
knowledge is presented at a too-specific level during knowledge
acquisition.

Each year there is a new group of industrial lecturers,
and the courses are not expected to be repeated.
Clarence (Skip) Ellis (Xerox PARC)
Office Information Systems Design.
Technology, techniques, and design paradigms of electronic office
information systems. The objective is to present a coherent and cohesive
foundation for the understanding and analysis of office systems and
their implementation. Topics include: basic components and media such as
word processors, workstations, PBXs, and local area networks; office
firmware such as RasterOps, virtual keyboards, phone handlers, and
window managers; office system elements such as document editors, mail
systems, calendaring systems, and distributed servers. The course will
describe and discuss issues of user interfaces, user programming, office
modeling, and the social / organizational structures within which the
technology must exist. Prerequisites: computer organization (e.g.
cs111,cs112), computer software (e.g. cs142,cs146).
Fall 84 only.
Joe Halpern (IBM San Jose)
400B Reasoning about Knowledge. Formal Systems for modeling aspects
of reasoning about knowledge, such as modal logic, nonmonotonic logic and
relevance logic will be considered. Discussions will address to what
extent these approaches can be used to deal with such problems as
reasoning in the presence of inconsistency, belief revision, and
knowledge representation. Familiarity with mathematical reasoning and
first-order logic will be assumed.
Winter quarter (Halpern) by arrangement.

1) We will have a student meeting on Wednesday, April 4, in the usual
place (Psychology basement, 420-041). Among other things, we'll be
electing TWO new bureaucrats, one to start this quarter and one next
(Kim McCall, elected bureaucrat at the last student meeting, won't be
able to serve spring quarter because of other departmental
obligations).
We've decided to solicit bureaucrat nominations electronically now,
but we'll actually vote on them at the meeting (the two with the most
votes at the meeting will be our new bureaucrats)---we'll announce who
the nominees are a few days before the meeting, but there won't be any
primaries, caucuses, straw polls, or other beauty contests beforehand.
So, over the next few weeks, send us your nominations.
2) Gio Wiederhold, chairman of the `Royalty Committee' described
below, would like one more student volunteer (Rich Pattis is already
on it); he'd prefer one who has not been involved in book production.
Here's his message:
-----
I have been asked to set up an ad-hoc committee to look into the
issues for book production and royalties at the Stanford CSD facilities.
The global question is: should the CS department be a partial beneficiary
of the income generated from books produced using CSD computer facilities,
staff, and other resources. Other resources could include the space and
attention provided to faculty and students while they are working on
such books.
It is a complex question and at most we could illuminate the issues and
present some alternatives. A report to the April CSD senior faculty meeting
is desired.
Questions to be raised include:
Does it include all books or only those which are written for large-scale
reproduction? Traditionally theses, even if published, and other research
monographs are sufficiently desirable that departments are willing to subsidize
such efforts. Maybe this questions is moot when we consider a percentage,
and perhaps also a threshold applied to the royalty. Then popularity speaks
for itself.
What is the relationship to funding sources? Most production and staff costs
ore supported by research grants. Some costs have been paid directly by
the authors or their publishers, specifically the costs for photo-typesetting
supplies. Should source of support make a difference?
At Stanford and most universities the tradition has that the authors hold
the right to intellectual property. This right is now modified in the case
of software, where Stanford desires a 1/3 university and a 1/3 department
share, leaving a 1/3 author share.
Should a sharing policy by the department be enforced or be a suggestion only.
Should the CS department be listed in the publishers' royalty distribution
list? Can a policy be enforced, especially with authors who have shared
affilitation?
I suggest that we would need at least three meetings:
1 brainstorming and ideas
2 formalize the points
3 summarize and complete a report.
Gio 3MAR84
-----
If you're interested in volunteering for this committee and will be
around for most of the month of March, send us a message. Also if you
have any comments about these issues, you can send them to the student
committee members, whom we'll announce once someone volunteers.

Hi John,
The discussion session I invited you to be guest for is Thursday,
March 15, 9:30-11:30am, in MJ 352. CS229b is a course oriented to qual
preparation. It consists of reading, student-only discussion sessions on
Tuesdays (9:30-12), and discussions with a guest on Thursdays (9:30-11:30).
The course is organized around one topic per week. Our last week is,
however, miscellaneous, which we have decided to devote to issues of:
supercomputer architecture for AI
programming languages for AI
evaluating AI systems
The class has expressed desire to have you be our guest to discuss these and
your general thoughts on AI.
Our format with guest discussions is informal, basically question-and-answer.
Please feel no responsibility to prepare anything. If you'd like to make
some opening remarks for say half an hour, that's fine.
Please let me know if you'll be able to come, as soon as you can.

I really enjoyed getting the opportunity to talk with you at length this
afternoon. I'm quite busy these days what with qual, probabilities, and
programming project, but I will keep thinking about circumscription and
nonmonotonicity.

There will be a large gap in our lives without him. He had many things
going when he got sick. I am committed to continue the history project.
Ithiel wants me to find someone to do it with at MIT. The last thing he
asked me to do on Friday night was to talk to my advisory board this
week and try to find where & who to deal with here, otherwise to look
for some similar place outside of MIT, possibly the Computer Museum.
We are meeting on Friday. Sloan has given me an extension of our grant
until June, mostly to prepare a proposal to them (or others) for
continuation. Art Singer of Sloan likes what he saw so far, and is very
enthusiastic o about the project. But Sloan may not want to fund all of
it next time, or may want some other sponsors as well as their funds,
for video is expensive. I'm sorry you did not see the tapes, perhaps
after we clean up some segments, I will be able to send you a cassette
to look at.
Anyway, we are open to any suggestions about continuation, more tapg
tapings, etc. Sloan is particularly interested in how such tapes can be
use in educational institutions, and not so much in the archiving
problems. They would rather let someone else worry about archives,
though they appreciate the need to keep these tapes for a long time.
Let's keep in touch on this.
The memorial service is set for Friday after this, March 23, at 2 PM, in
the MIT chapel, in case you know of anyone who may be here and wants to
go. Unfortunately, the Boston Globe got the date wrong. Ithiel would
have thought that pretty funny and indicative of how the press works!
The last week was pretty bad for him. I saw him twice, and was going to
see him Sunday again. He apparently was in pain, but continued to work
up to the end, giving me a list ofthings to do over the weekend, as
usual. I managed to show him the edited tape and some other stuff, and
he proofread the final report and made some good suggestions, but could
barely write. All of the graduate students are pretty broken up over
it; I don't think we were prepared for the end coming so quickly. The

some problem with keeping their activities in the right line (e.g., for

John,
We received a letter which responds to your Presidential MSG. I'd like
to include in the next issue their response and your rebuttal.
Claudia
Dear Editor:
In the previous issue's President's Quarterly Message (AI Magazine,
Vol. 4, No. 4), John McCarthy quoted part of a net message from Jon
Doyle, a faculty member here at CMU, to the effect that the students
at CMU are not very interested in fundamental questions, open
problems, and basic research. As graduate students in artificial
intelligence at CMU, we feel that while the over-all article is
clearly directed toward the general case of a real problem, this
introduction gives rise to several unwarranted implications, which
we would like to counter.
First, it should be noted that Jon Doyle stated that his conclusion
was "tentative", whereas John McCarthy refers to it as "definite".
In fact, it was a tentative conclusion, based on attendance at and
responsiveness to introductory lectures about the various faculty
members' interests. This could be an indication of interest, or it
could be an indication that applications are easier to appreciate
during one's first month in graduate school. It should be noted that
most of the students here are engaged in what they consider basic
research, though probably not pure theory (see below).
Secondly, the tone seems to be one of "you students aren't interested
in basic research", rather than that of the title, which is that
"basic research isn't emphasized enough". Clearly, basic research
needs more deliberate emphasis than applications, in AI as in any
science, since the usefulness of applications is always apparent, the
relative quantity of basic research is small, and the importance of
basic research is always hard to impress on the public. An arriving
student's first guess at a research interest is likely to be shaped by
the media attention given it, although one expects the actual research
topic eventually pursued will be the result of deeper inquiry.
Finally, there is an implication, refuted later in the article, that
there are no basic research issues involved in either natural language
or expert systems. There are at least three levels of "depth" in
research: purely theoretical research, basic research involving a
problem domain such as natural language, and "big, build-it-now"
application systems. Bothy types of basic research are less "flashy"
than applications, and require more conscious emphasis than
applications to receive equal attention.

I would think that this is a good idea. But I would put on some controls
to protect the good name of AAAI (which they represent), namely have them
give us a short summary ("bylaws") on how they plan to operate: How
officers are elected, what dues are collected, etc. To my mind these
need not be consistent between chapters but we should know what they are.

@b{John McCarthy},
Professor of Computer Science.@\
Professor McCarthy has worked in the area of formal reasoning applied to
computer science and artificial intelligence since 1957. He has recently
developed a technique for
completely characterizing LISP and other recursive programs within
first order logic by supplementing Cartwright's first order form of the
functional equation by a minimization schema.
This technique is well suited to automatic
proof checking, and in collaboration with Cartwright and Stanford students
Professor McCarthy is exploiting this breakthrough
by verifying more complex programs directly within first order logic. In
addition many of the standard program verification techniques can be
represented by axiom schemas in this system. Recently McCarthy has
discovered how to represent facts about knowledge and belief in unmodified
order logic and the solution works no matter how many mental
qualities must be treated.
He has also recently discovered that an axiom schema of first
order logic called a minimization schema can be used to represent in a
flexible way the conjecture that the entities that can be shown to exist
on the basis of the information in a certain data base are all the
relevant entities that exist. This conjecture is a common feature of
human reasoning. Professor McCarthy has investigated continuous
functionals that don't arise from simple recursive programs. Some of them
require parallel evaluation, and the work may lead to a treatment of
program correctness that unifies parallel programs with the more usual
sequential programs.
In 1979 McCarthy developed a new formalism called ``Elephant'' for
expressing sequential programs as sentences in first order logic.
The formalism permits programmers to avoid defining some data structures
by referring explicitly to the past.

All Greater Extended `O' Program Members:
In celebration of the attainment of the Vernal Equinox and a fully
functional S-1 Memory Box, there will be a party next Saturday, 24 March,
starting at 1400 hours (and running 'til PMF closes down the seemingly
inevitable poker game).
This gala event will occur at the Sty In The Sky (the entry point to which
is 4.2 miles north of I-580 on N. Vasco Rd.; close the barbed wire gate
across the splendid new blacktopped driveway entrance on the left-hand
side of Vasco Road after you pass through it). It will feature the usual
picnic/barbeque-style eat-ables and locally favored drink-ables; if you
want something more exotic, feel perfectly free to bring it along.
Highlights of the afternoon/evening (in addition to watching FM, JMB, OTA,
and PMF slug it out for their pooled paychecks) include all expense-paid
tours by PMF of his notorious hot tub salon, by RAH of his fabulous new
library, and by LLW of his recently established orchards; in addition, the
Sty's newly functional solar heating system will be demonstrated for the
incredulous. Most importantly, any virgins which have been obtained will
be sacrificed in the traditional fashion, and JMB will formally award the
stakes of the now-famous EAK-LLW wager on Memory Box functionality-
availability to the proper recipient (at last!).
Come and bring your spouse, semi(-demi-hemi)-spouse, offspring, etc for
another of the blowouts that leaves the whole Lab buzzing for weeks
afterwards!
RSVP to Gloria or Paula, or be thrown to the local pack of wild animals
(including the Sty's infamous Killer Cat) when you show up unexpectedly.

Dear John
Thanks for your proof on circumscribing an existential. I now see what I
overlooked.
Re a convincing example where circumscription yields a disjunction. How about
the following:
In a taxonomy we usually have a number of necessary conditions on a class, e.g.
DOG(x) --> MAMMAL(x)
CAT(x) --> MAMMAL(x)
etc.
If we have reason to believe that our taxonomy exhausts the class of mammals,
we can circumscribe the predicate MAMMAL to obtain
MAMMAL(x) --> DOG(x) V CAT(x) V...
Is this the kind of example you were seeking?
Regards, Ray.
PS The search continues for a proof that circumscription cannot yield new
inequalities. The old "proof" failed for theories without minimal models. We
conjecture that universally quantified Horn theories always have minimal
models and therefore for such theories, circumscription yields nothing new
about inequalities.

Thanks for the copy of Reiter's note. Boy, is that ever opening a can
of worms.
It follows from the fact that
bird(x) ∧ ¬ab(x) → fly(x)
that
bird(x) ∧ ¬ab(x) → ¬ostrich(x).
It seems likely to me that, for each specific type of bird, we will have
that a bird is not of that type specifically unless it is abnormal in
some fashion. If we can really circumsribe to get a disjunction, then
we will circumscribe to get
bird(x) → ab1(x) ∨ ab2(x) ∨ ... ∨ abn(x)
and I do not think that we really look at things this way.
Bear in mind, though, that I am writing this reply about 20 seconds

I believe that there is academic benefit to having students learn about
different operating systems if they are so inclined. In the Computer
Science Dept., we are quite fortunate to have UNIX (on many VAXen,
including NAVAJO), WAITS (SAIL), and TOPS-20 (LOTS-A, LOTS-B, and SCORE).
Students get some access to TOPS-20 on LOTS-A and LOTS-B. The CS Dept.,
however, has essentially forced all of its students on SCORE, and is
making it deliberately difficult for students to use SAIL in addition to
or instead of SCORE. Perhaps this is because SCORE has software for
limiting computer charges and SAIL doesn't. However, we are overriding a
definite educational benefit for purely monetary considerations.
John McCarthy has proposed that students can do projects supervised by the
bureaucrats for subsidized computer time. Since these projects would
inure to the benefit of CSD-CF, such subsidization would be overhead and
not come from CSD's unrestricted funds. This seems like an eminently
reasonable approach, and I encourage its consideration as a way to provide
for a valid educational objective while ameliorating financial
considerations. Thank you for your time and interest.
Arthur
It seems to me that your memo is capable of being misunderstood and
needs clarification. You should be explicit that the projects in question
involve improving CSD-CF for all users and are not the students' own
research and that the payoff for the student is computer time that he
can use for his own research.

UNIX. It is my belief that we could have the stuff working on more than
one computer, but that it is probably easiest to get a first approximation
on SAIL using the NS software. Would you rather it be done on SAIL first
and then later elsewhere, or instead do it somewhere else later without
the experience of the SAIL implementation?
I don't suppose you like the software at SAIL that notifies you of new things

elegantly described as circumscription. I've done some examples and
developed some notation, especially for inheritance hierarchies with
exceptions. I've written up most of it in longhand form (convenient for

LOCATION: Chemistry Gazebo, between Physical & Organic Chemistry
TIME: 12:05
SPEAKER: Hisao Yamada
Department of Information Science
Faculty of Science, University of Tokyo
TOPIC: A Cerebral View of Task Optimality
in Japanese Text Typing
ABSTRACT:
We discuss an activity of typists' brains during touch typing, based
on knowledge of experimental psychology and cerebral physiology,
especially in connection with the functional laterization of cerebral
hemispheres. Our hypothesis is that a skilled copy typist depends
heavily on the cortical reflex in response to direct visual
information from a manuscript, but depends less on the linguistic
facility of the left hemisphere. As an indication of the validity of
the hypothesis, we report our results of the measurements of typists'
electroencephalograms (EEG) during Japanese touch typing. Our
findings are preliminary but they are compatible with the hypothesis.
Whereas the current AI efforts are mainly focusing their attention on
the logical reasoning aspect of our intellectual activities which is a
dominant function of the left cerebral hemisphere, the present
investigation concerns itself with a subconscious, intuitive and
reflexive function of our mind, for which the right cerebrum is
dominant.
A short introduction to Japanese input techniques is also included.
The talk is profusely illustrated with slides.

Hi John,
I managed to connect with Reiter on the phone this morning
for half an hour. He said that my approach sounds good, and confirms
his feelings about the relation of default logic to circumscription.
But it seems to be new.
In general he was encouraging. The deadline for submitting abstracts
for the Workshop has been extended tothe end of April. He said he'd like to
read whatever I get written.
Etherington is working on trying to show that circumscription
CANNOT hadle equality and unique names. Reiter pointed out that since
default logic can, I should try my approach on it. I will. He and
Etherington would appreciate prompt report of either positive or negative
progress on equality and unique names, since Etherington is actively
pursuing it.
Reiter agreed that Doyle's reasoned assumptions stuff is just
default logic. (One more down in trying to unify nonmonotonic reasoning
approaches!).
As far as general default rules go, Reiter commented neither
he nor Criscuolo nor anyone else that he knows of have found any use
for non- seminormal defaults, and moreover he has very little intuituion
on them.
Also, he recommends using a different net address than you have:
reiter@rutgers
I'll keep you posted of further developments....
Regards,
Benjamin

Subject: unique names and equality
To: jmc@SU-AI.ARPA
cc: grosof@SUMEX-AIM.ARPA
Hi John,
This may be very naive, but how about the following:
Reiter proposes to handle circumscribing inequality using
a default rule:
: Not-equal(x,y)
-------------------------
Not-equal(x,y)
I guess this is universally quantified to the left, i.e.
: NE(x,y)
ALL x,y. --------------
NE(x,y)
Using my mapping from default logic to circumscription, we can
describe this seminormal default rule as:
ALL x,y. ~ab[nNE](x,y) => NE(x,y)
This provides a single axiom in first order to handle inequality.
We then circumscribe ab[nNE], which is just a predicate.
Alternatively, we could think of this as circumscribing ab in a
more general context, where the above is rewritten:
ALL x,y. ~ab (aspect[nNE](x,y)) => NE(x,y)
"nNE" refers to "null antecedent, NE consequent" in line with the
indexing notation [a,w] I used in what I showed you yesterday.
The index doesn't matter. We could just write:
"ab1" or "ab (aspect1"
instead. The reason I included it, however, is to point out that we can
combine the inequality default, i.e. equality circumscription, with other
defaults/ circumscription.
What do you think?

Is there a suggestion here that Sail is usable only from special types of
terminals? That's certainly not true.
A system which can only be used effectively from hard-wired or modified
terminals lacks one important aspect of an information system: getting
data WHERE it is needed. ( it's fine for computation )
Although the display service is available remotely only on terminals that
have certain capabilities (such as insert-delete), the system still works
from other types of terminals. Maybe you're under the impression that
only terminals with "EDIT" keys can use the Sail display service. That's
not true either. I'm not sure what your point is here.
I find it indeed very difficult to deal with the SAIL keysequences away from
a DATADISC. Do you use SAIL that way? The fact that something can be
done doent mean that it is pleasant, and we want to make the bibliography/
library services available to many folk. Gio

Reply to:
Wiederhold%sumex,feigenbaum@SUMEX-AIM/cc,olumi@SU-SCORE,ME,Library%score
SAIL and the library's technical report list
I have used the SAIL display service from an unmodified Zenith. I would
have to say that it works but not as well as a terminal with an edit key.
Nonetheless, I believe that for the project we are contemplating, the
question is really moot. First, the news service programs can be used
quite effectively without using display service. If you don't use display
service, you don't have use for the features of a modified terminal.
Rather, you don't even use those features! There are considerable
simplifications in usage because the records are usually less than 10
lines long.
One thing of which you may not be aware is that Richard Manuck usually
uses SAIL as the first CSD machine that he puts the bi-monthly New Reports
List online. (He uses the DIAL program to transfer it from ITS. Does
your system have this facility? Is it as easy to use? Richard says that
the method he uses with SAIL's DIAL is significantly easier than the old
method he used in the past on SUMEX. He regularly lost chunks of data
using SUMEX, and has never lost any data using SAIL.) Richard then moves
the list to the other systems on which it resides. He could easily run an
easy-to-use program to supply the new data to the news service programs.
SAIL allows some things to be done while not logged in. SCORE allows
significantly fewer such things. You can look at files and search them
(if they are unprotected) at SAIL if you are not logged in. (However,
running the news service programs is currently not permitted when not
logged in.)
Clearly, people with SAIL accounts would have no problem accessing the
files effectively. There are several alternatives for people without
accounts on SAIL. We could encourage them to get accounts on SAIL (after
all, they would have to have accounts on SCORE if it were there). We
could have a program that runs on the user's computer that requests the
service from SAIL and keeps track of the charges that was incurred on the
user's behalf on SAIL. Alternatively, we could simply allow free and
unrestricted access to the data on SAIL until an equivalent system
appeared on SCORE. (Would the management of SCORE be willing to do that?)
There is no reason why we can't have the reports list up on more than one
system without much additional effort on the part of library personnel.
Why is there such an uproar about putting it on SAIL and narry a peep
about doing it on SCORE?
Thanks.

∂21-Mar-84 1628 DEK CHAIRPERSON SEARCH ENTERS CRITICAL PHASE!
To: "@FACULT.DIS[1,DEK]"@SU-AI.ARPA
On behalf of the Chairperson Search Committee, I'm pleased to report that
we received a dozen excellent applications, from which we have selected
three people for visits to the campus.
The first of these visits is imminent: Dennis Tsichritzis will be here
next Monday and Tuesday, March 26 and 27. (I'm sorry that I couldn't
arrange for more lead time; he must return to Europe soon, so this was
the only reasonable pair of days.) Nils Nilsson will be our guest on
Monday and Tuesday, April 9 and 10; and Ken Kennedy will be visiting us
on the following Monday and Tuesday, April 16 and 17.
These visits obviously will have a significant effect on the future of
our department, and I hope you will be able to help us make the best
choice. The candidates also will want to find out as much about us
as possible while they are here.
Each candidate will be giving a special lecture. The first of these,
entitled "Office filing and office mailing", will be by Dennis T.,
next Tuesday afternoon in Jordan at 4:15. (Note, NOT Terman!)
Besides this, the candidates will be at our regular Tuesday lunch;
there will be sandwiches available next Tuesday noon, even though
it's between quarters, because of Dennis's visit.
Many of you will also want to spend a few minutes meeting our visitors
personally. Please phone Phyllis (7-4367) for an appointment.
You might want to combine that with dinner at the faculty club;
I've left the Monday noons open for that.
And besides this, Jill and I will be hosting three dinner parties
on the respective Monday evenings, so that we can have informal
get-togethers. The first such gala occasion will be next Monday
evening, March 26, beginning at 6pm. [Our house is at 1063 Vernier
Place on campus.] You and your spouse/friend are cordially invited.
And that brings me to an important logistical point: I need to tell
the caterers soon (i.e., by Friday night) how many people to expect,
so that they can make the food. Therefore please RSVP to Phyllis
before, say, 4pm on Friday March 23, telling her if Jill and I should
expect 0, 1, or 2 people from your household. (I'm sorry that I wasn't
able to give more advance warning about this; I know that many of
you will have trouble arranging for baby sitters at such a late date.
Now if Iris can wait to have her baby until next Wednesday...)
OK, to summarize: Our search is entering its most important period.
I'm asking you to do this before Friday at 4pm: Call Phyllis to arrange
for a time to meet Dennis next Monday or Tuesday, and/or to RSVP
to the party invitation. Thanks for any help you can be to our search.

Elsie, that's Veronica not Victoria. I can pay 1/3 of the expenses.
I suggest that one of the organizations pay (not mine) and tell my
secretary Diana Hall (DFH@SU-AI) what our share is. Do you have titles
and abstracts yet of talks she can give.

He has applied to csli for a postdoc. He wasn't included among the winners,
but a negative decision was not really made either. He is so quiet that we
don't feel we know him very well, even though he has been coming to csli
events all year. His credentials are interesting. Can you tell us anything
about how he has interacted with you this year, and what you think of him,or
give us any advice?
-------
I'll phone you about Kuo, but I fear he is taking quite some time getting
used to this environment, so I haven't got a lot out of him either. I
suggest a long talk with him.

I've sent a letter to Victor apologizing for the tardiness in coming
to a decision about his status as a postdoctoral fellow at CSLI. I
told him that a decision would be forthcoming in a couple of weeks,
thinking that he shouldn't be held off any longer than that and
anticipating that either one or both of you could find a chance to

In your message of 18 Mar 84 15:29:32-PST you state that "our system of
government and our behavior as a world power is a LOT better than theirs
[the USSR], and worth defending; and we'd better keep our guard up."
I certainly agree that our system of government is "a LOT better than
theirs." But I can't agree that our international conduct is any
better. We have a nasty habit of overthrowing or undermining any
government we don't happen to like. We did it in Iran and Guatemala in
1954; in Chile in 1973; in the Dominican Republic in 1965 or so; even in
Australia in the late 1970's (see the latest issue of Mother Jones). We
installed the Somoza dictatorship in Nicaragua. We tried and failed to
overthrow Castro by invasion in 1961, and we're trying to get rid of the
Sandinistas in Nicaragua right now. Furthermore some of the governments
that we support (Chile, El Salvador, Guatemala, the Philippines) are the
kind of people we fought World War II to stop.
If you put that record up against Soviet misbehavior in Czechoslovakia,
Hungary, Poland, East Germany, Afghanistan, and the rest of the
well-known list, wouldn't you say the scales are pretty balanced?

Hi John,
Below is a draft of an announcement of the nonmonotonic seminar proposal.
I have taken the liberty of speculating as to possible topics. Circumscription
appears to be heavily represented. I'd like your comments, especially with
regard to speakers and topics. The parts with question marks I will include
only in a limited distribution to potential speakers. The more
general-distribution announcement will of course be briefer and more
circumspect than to include the speculations herein.
Especially, what do you think of my speculations as to topics for you, Reiter
Etherington, and Leslie Pack?
--Benjamin
John McCarthy has asked me to try to arrange a seminar in
nonmonotonic reasoning for this spring. I was thinking along the
lines of meeting once every one or two weeks.
Below is a list of possible speakers and topics. Only the first <three>
speakers (and not even their topics) are more than hypothetical at this
point, since they haven't even been approached yet.
Please respond if you are interested, and indicate what your interests are.
Suggestions (and especially offers) with respect to speakers and topics are
of the highest priority, and are greatly appreciated.

Barwise and Perry have convinced me that it would be better to shift to
their computer and one of their terminals when I return in the summer.
I understand that all the files I currently have can be automatically
transferred at that point. However I suppose my Sail account should be
kept open until then. It would be most convenient if you , or someone
acting on your behalf, could come and get the terminal sometime this
Wednesday, preferably by 1 P.M.
I think you said that should not be too much trouble.
I awant to thank you for the extended loan of the terminal. It has been
very useful and has served as a good introduction to the possibilities
of such an apparatus. Thanks again for all your help and initial advice.
Please let me know when the terminal will be picked up. Sol

John,
Carolyn mentioned to me your generous offer to pick up my SAIL costs if I
can't find anyone else to support my research. I'm talking to a number of
potential patrons whose interests are closer to mine, but at the moment
it's difficult to predict the outcome of our negotiations. I hope that I
won't have to take you up on your offer, but it's very reassuring to me to
know that there will be a way for me to continue my work on SAIL, since
transporting it elsewhere would be very inconvenient at this stage.
Thanks again.

As previously noted, grades for winter quarter courses are due today.
If the end of quarter reports are not turned in by the deadline,
students will receive a grade of "incomplete" on their records.
Thus some students planning to graduate winter quarter will be unable
to do so, because his grade was not reported on time.
Please turn the end of quarter reports in as soon as possible. Put
them in my mailbox, or bring them to my office (256 mjh) today, or
tomorrow before 10 (at the latest).
Thank you for your kind attention to this request.

Bruce (and John and Ed),
As Ed suggested, I looked up myself and others in AI in the
Compumath Citation Index (which is the relevant specialization of
the Science Citation Index) in our library. Harry Lull was
quite helpful in this, by the way. Anyway, here are the results.
I come out favorably according to this measure, compared to almost
everyone. There are some exceptions (textbook-writers and
Randy Davis, in particular). If you want to use some or all of
this data in the papers or future dealings with the dean, please
feel free to do so. This index is only one database, albeit
the most relevant to AI. In another DB, the Social Science one,
there another 49 citations of my work (1975-84), for instance.
Below, I have reported all citations, in the years shown, for
articles and books which were written after 1974.

Keep in mind that this is only citations of post-1974 works
(so Nils' early books, and N&S's Human Problem Solving, e.g.,
are not included here), since MY paper publishing begins in 1975.
Also keep in mind that this is only CS-related publications; if
one searches the Social Science data base with the same people,
there some dramatic changes (e.g., Winograd and Suppes gain about
500 citations, many people on the list gain 0, and Lenat gains 49).
It is also worth noting the upward trend in my citations, which
I expect will continue a few more years (at least!) due to the
forthcomingpublication of Nature of Heuristics IV in AIJ, and the
Sci. American Articles (which raise publicity if not direct citations),
and due to the fact that many of my publications were in the last
12-18 months, so haven't been cited yet by those who will eventually
do so. A final note: this is all the data I collected, these aren't
a selected set to make me look good. E.g., I really wish I hadn't
looked Randy up! I intentionally did not look Winston up, because
I expected almost all his citations would be to textbooks and
the Computer Vision book he edited, and the MIT AI Lab reports he
edited. I also didn't look Simon up; that was simply an oversight.
I could look up more people, now that I think of it
(Stan Rosenschein, Johann deKleer,...), but the list above
gives a representative sampling of AI, young AI, and machine
learning researchers. I was disappointed in my listing, until
I saw everyone else's. Of course our conference proceedings,
even though refereed, don't get entered, or we'd all have
many times as many citations.
Cheers,
Doug

Subject: determinism and choice
I am most in sympathy with the point of view expressed by DAM. It is
expressed more elaborately in McCarthy and Hayes, "Some Philosophical
Problems from the Standpoint of Artificial Intelligence", Machine
Intelligence 4. The essence is that what a person or machine
CAN DO is determined by its position in the interaction structure
rather than by its internal structure. The latter determines what
it will do. This general idea is variously decorated in the paper.
I agree with DAM and with McCarthy on free willl and choice, although I think
DAM's statement (I wish I could excerpt it here, but I let it disappear a few
days ago) while more informal than JMC's also thereby catches a twist that
the McC and Hayes approach may miss, namely, that the internal structure
itself can be a crucial factor in what is a possible choice. For instance,
suppose I have an inherent incapacity to jump higher than 4 feet. This then
is a factor of importance in my deciding whether a plan involving jumping
is feasible. If the jump required is less than 4 feet, I may still consider
it in the realm of things open to me to do; but otherwise not (assuming I
have such knoweledge about my juimpoing limitations). Since it appears that
often we do and often we do not have such knowledge, then the choice set
should perhaps be defined in terms of ones explicit knowledge, in general,
rather than in terms of interanl versus external data. After all, it may
be that in fact I cannot even jump 2 feet due to unknown factors ( I may have
injured may leg and not realize it, or the floor may be to soft to support
a vigorous leap) and still a 3 foot jump may be (appropriately, as far as
I can be expected to know) one of the 'choices' I entertain.

determinism and choice
McC and Hayes suggests treating the phenomenon mentioned by Perlis as follows.
Regard the brain, (or perhaps better the mind, since the form of physical
implementation is not relevant) as composed of interacting parts. What one
part can do depends on its position in the causal structure, and this takes
into account the other parts. For example, the folk psychology decomposition
of the mind into Will and Intellect works pretty well for
Perlis's example of jumping provided we add the Body as a part. Namely,
the Body can jump 4 feet, because it has outputs that would do it. However,
if the Will tells the Intellect to do it, the Intellect won't emit the
required order to the Body, so the Will can't. This may not be quite right,
but we will have to provide our robot programs with some kind of
notion of CAN based on interaction structure so that it will explore its
options and decide what to do in some reasonable way.

I got a note from you on the "Marek" paper.
Probably there were previous messages that got lost because of the
diablo crash (jef@sail forwards to diablo)
Can you go over this again?
I had a question about database notation, specifically what does X →→ Y
mean, but ARK answered it for me. The Marek paper purports to provide a
proper semantics for the McDermott-Doyle non-monotonic logic using
model-theoretic forcing, but this seems to me a bit like using a
sledge hammer to kill a fly, since forcing really gets its power in
infinite domains. Marek takes his examples from database theory. If
you're interested, I can supply a copy of the Marek note. You need
a computer like SAIL that takes regular disk dumps. I haven't
permanently lost a file since 1969.

Gabi Kuper might be interested, since he looked at McDermott's

By the way, the problem with diablo was a bit more interesting.
In principle, SUMEX, which runs it, takes dumps every other day.
However, the guy they hired to do the job was simply labeling
tapes with the date and not doing the dump.
I'm not sure, but I think any suggestions on how to make the
punishment fit the crime would be welcomed by Ed Pattermann.

Good point. However, the uncertainty principle of quantum mechanics
would seem to limit the extent to which the interaction structure
determines what a system will do. It may be that the macroscopic behavior
of people is not much affected by quantum level effects. But I don't know any
good arguments why this should be the case.

be that the macroscopic behavior of people is not much affected
by quantum level effects. But I don't know any good arguments

There is a good reason for quantum effects not being present at
the scale we live in. The group statistics washes them out. The
exact behavior of the ensemble depends on the statistics:
Bose-Einstein
Fermi-Dirac
Maxwell-Boltzman
Typical everyday ensembles obey Maxwell-Boltzman (I think) in
which many of the quantum effects are washed out. (However other
ensembles such as super-conducting materials obey other
statistics (Fermi-Dirac?) in which some of the quantum effects
are shown by the ensemble.

I'm not sure I follow this. My point was that the reasoning mechanisms
themselves must be included, in some cases, as part of the 'causal
interaction structure,' and that no part of it is immune from this. As
a consequence, self-reference might be required. This struck me as at
least implicit in DAM's original comments. Self-reference here is not
just of one part to another, but of one part to *itself*, e.g. the
intellect may know its *own* limitations, such as to reason fast enough
to find a solution to a certain kind of problem before its too late.
As for JMC's statement about the body being able to jump 4 feet, even if
the will and the intellect are prepared to emit such orders, the body
still may fail for physical reasons; if the intellect is aware of these
limitations, it (the intellect) may still order the motion (say in
desperation), yet we wouldn't want to say that the body (or the individual)
was then capable of the impossible jump, or even that the individual thought
itself so capable, I think.
I don't believe that this presents insurmountable problems for the McC&Hayes
account; but it does strike me as a point worth separate mention.

Because of his new MCC duties, Woody has resigned as
chairman of the committee at the University of Texas that is
trying to fill new chairs.
The new chairman of the committee is Mani Chandy, who is
also chairman of the CS department.
Mani has asked me to talk with you about the idea of your
coming to Texas. I believe that at some point, your and
Carolyn's visiting for a week was discussed, but not much
has been said for months. Are you interested? It's my
guess that you don't have the time or interest right now,
but it would be good (good for us) to hear whether
you are interested in a visit.
I am not on the search committee, but it is my understanding
that you are the only one of the first ten people that UT
approached who has not given a definite signal. Dijkstra
has accepted, and the others have said "No" or "Not now".
You should definitely understand that a "Not now" is a
signal that you could give and yet still reopen the subject
later. Mani indicated that even if the current positions
were filled, a chair for someone like you could be created
if you ever became interested.
On a more scientific plane --
An Indian student named Shankar has been using our
theorem-prover to do some proofs in metamathematics. He has
formalized Shoenfield's logic as a collection of functions
in our theorem-prover's theory and has proved a number of
Shoenfield's proof-theory theorems. The most interesting is
a proof that for any "tautology" one can give a proof
(grinding everything out with modus ponens, etc.). He has
been working on the famous theorems of Goedel and Church.
It is a surprise to me that in the case of Goedel's first
theorem on unprovable statements, the easy part, from the
point of view of proof checking, is that which is commonly
regarded as the heart of the argument. The hard (long,
anyway) part however is the tedious business of showing that
any primitive recursive function can be imitated from within
an elementary set theory or number theory.
Moore and I have almost finished constructing a version of
our system that handles bounded quantification. One
interesting proof was that of the Binomial Theorem, where
sigma manipulation is standard.

Agenda:
12:15-12:30 -- eat lunch
12:30-1:00 discuss AA questions
1:00-4:30(?) -- discuss remaining sections
The faculty lunch that day will last until 1:00ish. Nils Nilsson will be
there. So I expect that some faculty members of the committee will
be at the faculty lunch. I've scheduled the AA section because Dave
Foulser and I will be present to defend it and enough student and faculty
members will be around to attack it.

The anthology, "Free Will and Determinism" edited by Bernard Berofsky
(Harper and Row, 1966) contains several such papers.
In particular, the papers of Hobart and Foot address this very question,
Hobart on 'our' side, and Foot against. Both give some additional
references, esp. Foot. Also, John Stuart Mill in the same volume has
an essay with a broadly sympathetic outlook. The papers of Davidson and
MacIntyre are of interest as well.
Finally, Austin goes into 'choosing' at great length, at times bordering
on statements similar to DAM's, I think, but I have not examined the
former with any care.

Date: 23 Mar 1984 1214-EST (Friday)
From: mit-athena!dm@mit-eddie (Dave Mankins )
Subject: Notes from talk by Alan Kay at MIT
Dr. Alan Kay, one of the developers of Smalltalk and the Xerox Alto, and
currently a Vice President and Chief Scientist at Atari, gave a talk at
MIT yesterday (22 March 1984) titled: "Too many smart people: a personal
view of design in the computer field"
The abstract:
This talk is about the battle between Form and Content in Design and
why "being smart" ususally causes content to lose. "Insightful
laziness" is better because (1) it takes maximum advantage of others
work and (2) it encourages "rotating" the problem into its simplest
essence -- often by changing it completely. In other words: Point
of view is worth 80 IQ points!
Here are some tidbits gleaned from my notes:
One of the problems with smart people is that they deal with
difficulties by fixing them, rather than taking the difficulty as a
symptom of a flaw in the design, and noticing "a rotation into a new
simplicity."
When preparing his talk he realized that what he wanted to say was
basically inconsistent, that
1) You should do things over, and
2) You shouldn't do things over.
"Both of these are true as long as you get the boundary conditions
right." (There ensues an anecdote about working with Seymour Cray to
get an early CDC6500 up at NCAR. The 6500 hardware did not normalize
its floating point operations, but that was "okay" because "any sensible
model will converge". When the NCAR meteorologists (who answer the
question "what will the weather be like?" by looking out the window)
tried to put their models up on the CDC6500, they didn't work. They
insisted that the Fortran compiler do the normalization for them. Kay
cited this as evidence that their model was wrong. Hmph, it's easy to
make fun of meteorologists...)
Kay cited Minsky's Turing award lecture, in the Apr. 1970 JACM (or maybe
CACM, I didn't catch it): "Form and content aren't enough." What has
happened to the computer science field over the last twenty years is
myopia: "a myopia so acute that only the very brilliant can achieve
it."
As an example of this, Kay cited the decline from the STS940 in 1965 to
UNIX ("a mere shadow of what an operating system should be") to CPM. The
myopia in question is best illustrated by a failure of Kay's own: "When
we got our first IMSAI (mumble) we put Smalltalk up on it. We had to do
a lot of machine coding on it, and we thought that wasn't right. And it
performed about as well as BASIC does today. We said 'This is clearly
inadequate. What we need is 2Mb of memory and a fast disk.' Thus we
left the door open for BASIC to crawl back out of its crypt."
He should be lynched. At least he realizes the error of his ways.
He cited an article by Vannevar Bush, in a 1945 Atlantic Monthly,
titled, "As we may think", in which Bush described a multi-screened,
pointer-based system with access to the world's libraries, drawing
programs, etc. Bush, of course, thought it was just a few years away
(he called it "Memex").
He alluded to Minsky's notion of "science-envy": Natural scientists look
at the universe and discover its laws. Computer scientists make up
their universes. "What we do is more like an art." "You can judge
whether or not a field is overcome by science-envy if it sticks the word
'science' into its name: 'computer science', 'cognitive science',
'political science'..."
He talked about some of his early work, with Ed Teitel, developing an
early personal computer (ca. 1965) calligraphic display with a pointer.
It had "a wonderful language I developed, influenced by Sutherland's
Sketchpad (the best thesis ever done in computer science) and
Simula--everything I've ever done has been influenced by Sketchpad and
Simula). Everyone who tried to use it hated it. They all had about the
same reaction to it that everyone has to APL today." Shortly after
working on this he saw Papert's work with LOGO and children, and
resolved that everything he did from that day forth would be
programmable by children.
Part of the machine's problem stemmed from the fact that it didn't have
enough memory. This in turn stems from the fact that we cast hardware
in concrete before we know what we're going to do with it.
Some relevant maxims from my notes:
"Hardware is software crysallized early."
"We shouldn't try to build a supercomputer until we have something
to compute."
His point in these two maxims was, I think, that we're very good at
building hardware before we really know what we're going to do with it
(is there a lesson here for Project Athena with its tons of Ethernetted
VAXes "which will be used for undergraduate education" but a lack of
vision when it comes to educational software?)
He then described the Dynabook: a note-book sized interactive computer,
with about the same kind of interface as a notebook: you can doodle with
it, scribble, but it can also peruse the whole Library of Congress, as
well as past doodles. "So portable you can carry something else, too."
[For a more complete description of Dynabook, see ``Fanatic Life and
Symbolic Death among the Computer Bums'', in "Two Cybernetic Frontiers"
by Stewart Brand.]
[An aside: one of the proposed forms of the Dynabook was a Walkman with
eyeglass flat-screen stereoptic displays (real 3-d complete with hidden
surfaces!). This was punted because "no one would want to put something
on their head." (Times change.) Kay asserted that such displays ought
to be easier to produce than a note-book sized display, since there
would be fewer picture-elements required (a notebook would require maybe
1.5M pixels, while "the human eye can resolve only 140,000 points, so
you'd only have to put 140,000 pixels into your eyeglasses". The flaw
in this argument is that most of those points the eye can resolve are in
the fovea, and you would have to put foveal-resolution over the entire
field of the glasses, meaning, more pixels. This is the opposite of
window-oriented displays. Instead of a cluttered desk you have an
orderly bulletin-board: just display everything at once, the user
can look around the room at all the stuff. If this room isn't enough
you can walk into the next room and look at more stuff.]
More maxims:
"Great ideas are better than good ones because they both take about
the same amount of time to develop and the great ideas aren't
obsolete when you're done."
An observation:
"In all the years that we had the Altos no one at Xerox ever
designed anything by starting with a drawing on an Alto. They
always started with a sketch on the back of an envelope."
Nicholas Negroponte and the Architecture Machine (ArcMac) group
did the only study of what sketching is and what really is going
on when you sketch in 1970 in a project called "Architecture by
yourself" but their funding dried up and no one remembers that
stuff now.
[An aside: the Macintosh's MacPaint program is the best drawing
program that Kay has ever seen. (The Macintosh people called him
up one day and said, "Come on over, we have a present for you.")
When he started playing with it he had a two-fold reaction:
"Finally", and "Why did it take 12 years?"]
Homage was paid to the Burroughs B5000, a computer developed in 1961:
It's operating system was entirely written in a higher level
language (ALGOL)
It had hardware protection (which was later recognized to be
a capability protection system)
It had an object-oriented virtual memory system
It had virtual data
(any data reference could have a procedure attached to it for
fetching and storing the real data--a bit was set as to which
side of the assignment statement it went on)
It was a multiprocessor (it had two processors, and much of the
protection scheme was built in order to allow the two processors
to work together).
It had an integrated stack (which, sadly, is the only thing that
people seem to remember).
"This was twenty years ago! What happened, people?"
The B5000 had some flaws:
The virtual data wasn't done right
there were too many architectural assumptions about physical data
formats
"Char mode: which eliminated all the protections." This was
provided to let programmers used to the 1401 (I think) be
comfortable.
User interface observations:
Piaget's three stages of development:
Doing ----> Images -----> Symbols
doing: "a hole is to dig"
images: "getting the answer wrong in the water glass experiment"
symbols: "so we can say things that aren't true"
Brunner did a study that indicated these weren't stages, they were three
areas conflicting for dominance--as we mature, symbols begin to win out.
Ha...man did a study of inventiveness and creativity among
mathematicians and discovered that most mathematicians do their work
imagistically, very few of them work by manipulating symbols. Some
mathematicians (notably Einstein) actually have a kinesthetic ability to
FEEL the spaces they are dealing with.
From psychology comes a principle applicable to user interfaces:
Kay's law: Doing with Images generates Symbols.
He cites Papert's "Mindstorms", where Papert describes programming a
computer to draw a circle. A high school student, working with BASIC
would have before her the dubious assertion that a circle and
x**2+y**2=C are related. A child, instructed to "play turtle" will
close her eyes while walking in a circle and say "I move forward a
little, then I turn a little, and I keep doing that until I make a
circle". This is how a differential geometer views a circle. Papert's
whole book is an illustration of Kay's Law.
User interface maxims:
Immediacy
What you see is what you get (WYSIWYG)
Modeless
Always be able to start a new command without having to clean up
after the old one.
Generic
What works in one place works in another
User illusion
User's make models of what goes on inside the machine. Make the
system in which most of the user's guesses are valid. Not "some
of the time it's wonderful, but most of the time you get
surprised."
Communicative
He drew the distinction between reactive systems and interactive
systems. All his systems have been reactive--you would do
something, and the system would react, opening up new
possibilities.
Undoability
Even if it doesn't do much, if you never lose a character, your
users will be happy.
Functional
"What will it do without user programming."
He didn't used to think this was a user interface issue until he
saw the STAR, which has the world's best user interface, except
that it doesn't DO anything. Not many people can affort a 17000
coffee-warmer.
Fun
One should be able to fool around with no goal. A user
interface should be like Disneyland
"Language is an extension of gestures--you're not really trying to say
something, you're really trying to point to something that is in someone
else's head. A good mime can convey a message without a single word."
A model he encourages people to pursue is that of the AGENT. When you
go into a libratry, you don't expect an oracle, you expect someone who
knows how to find what you're looking for. It is much easier to make an
expert about the terrain of knowledge than an expert that can deal with
the knowledge itself.
He then played a videotape of a "telephone answering machine" being
developed by ArcMac (with funding from Atari). It listened to the
pattern of a person's speech (in order to figure out when the person was
pausing long enough to be politely interrupted) and then channelled the
conversation into a context (that of taking a message) that the machine
could deal with. It has a limited speech recognition ability, which
allows its owner to leave messages for other people:
Hello, this is Doug's telephone, Doug isn't in right now, can I tell
him who called?
Uh, Clem...
If you'd like to leave Doug a message, I can give it to him, otherwise
just hang up and I'll tell him you called.
Doug, I'm going to be in town next Tuesday and I'd like to get
together with you to discuss the Memory project....
Thank you, I'll tell him you called.
and
Hello, this is Doug's telephone, Doug isn't in right now, can I tell
him who called?
It's me...
Hi, Doug, you have three messages.
Who are they from?...
One is from UhClem, one is from Joe, and you have a mail message
from Bill about the Future Fair.
Tell me what UhClem has to say...
[The machine plays a recording of Clem's message]
Take a message for UhClem...
Recording.
Dinner next Tuesday is fine, how about Mary Chung's?
And so on. UhClem calls later, and the machine plays back the recording
of Doug's message.
POINT OF VIEW IS WORTH 80 IQ POINTS:
"A couple of years after Xerox punted the Alto, I met the people who
made that decision. They weren't dunces, as I had originally
supposed, they just didn't have the right point of view: they had no
criteria by which to tell the difference between an 8080 based word
processor and a personal computer."

Don Perlis has agreed to your suggestion that someone develop a bibliography
on non-monotonic reasoning in time to be distributed at the Workshop in
October. He will send a message over the ARPA and CS nets requesting
inputs and will request inputs from those who we know are doing work in this
field. Could you send Don any information you have re people or citations
that would be useful. If you would send the names and NET addresses he
will send requests to individuals. Is it possilble to get a notice into
SIGART or the AI Magazine with a request for information?
Don already has a fair sized bibliography and is anxious to expand it for
the Workshop.

As far as I can see step 27 loses information. See page 4
of bird.lsp[w84,jmc]. Namely, it loses the informtion that
ostriches can't fly. We have ∀x.ostrich x ∧ ¬ab aspect3 x ⊃ ¬flies x,
and ab2, which is substituted for ab is always false on
any aspect3 x.

Amazing: false∨false was simplified to true due to a typo in the rewriter.

I discovered that if I replaced ⊃ by ≡ in the second parts of my axiom 2,
the rewrites work. I thought they were advertised to work for ⊃. I now
have almost the result I want. I only lack showing that ostriches don't
fly even if they are birds. Most likely this is my fault rather than
that of EKL. Thanks for your help.
