Subject: VAX Lisp
Just looking for a little consumer information here - does anyone have
any experience with Digital's VAX LISP ? DEC advertises it as a
full-fledged implementation of CommonLisp. Any remarks on price,
performance, quality, etc are appreciated.

Subject: PC Lisps
[Forwarded from the MIT bboard by SASW@MIT-MC.]
Can some of you out there who have used Lisp implementations on IBM PC
type machines give me some recommendations as to the best PC Lisp? I
plan to run it on a PC/XT and a PC/AT if possible. Also, any expert systems
shells that run on the same machines, real or toy-like.

Subject: McDonnell Douglas NL Breakthrough
The following is the text of a full page color ad on page 49
in the June 24, 1985 New Yorker. It has also been run in the
Wall Street Journal. Does anyone know what the breakthrough
is? This was mentioned on the ailist some time ago but I
didn't notice a response. There is a photo of a hand holding
the chin of smiling boy.
BREAKTHROUGH: A COMPUTER THAT UNDERSTANDS YOU LIKE YOUR MOTHER
Having to learn letter-perfect software languages can be frustrating to the
average person trying to tap the power of a computer.
But practical thinkers at our McDonnell Douglas Computer Systems Company
have created the first computer that accepts you as you are - human.
They emulated the two halves of the brain with two-level software: One level
with a dictionary of facts and a second level to interpret them. The
resulting Natural Language processor understands everyday conversational
English. So it knows what you mean, no matter how you express yourself. It
also learns your idiosyncrasies, forgives your errors, and tells you how to
find out what you're looking for.
Now, virtually anyone who can read and write can use a computer.
We're creating breakthroughs not only in Artificial Intelligence but also in
health care, space manufacturing and aircraft.
We're McDonnell Douglas.
How can I learn more?

Subject: Optimal Scrabble
Anyone interested in computer Scrabble should be aware that Guy
Jacobson and Andrew Appel (some of the people that did Rog-o-matic)
have written a program which in some sense solves the problem. Using a
clever data structure, their program makes plays in a few seconds and
always makes the best possible play. Their dictionary is the official
Scrabble dictionary. The program is not completely optimal because it
doesn't take into account how the placement of its words near things
like triple word scores may help the other player, but in all other
senses it always makes the best play. I suppose some simple strategic
techniques could be added using a penalty function, but as the program
almost always wins anyway, this hasn't been done. It regularly gets
bingos (all seven letters used), makes clever plays that create three
or more words, and so on. The version they have now runs on Vax/Unix.
There was some work to port it to the (Fat) Macintosh but that is not
finished, mainly for lack of interest.

Subject: Predation/Cooperation (AIL v3 #78)
Re: enquiry of sdmartin@bbng about learning cooperation in predation:
For an extensive investigation of a minimal-domain model (prisoner's
dilemma),see _The Evolution of Co-operation_ (NY: Basic Books, 1984;
LC 83-45255, ISBN 0-465-02122-0) by Robert Axelrod (of the U of Mich).
He is in the Institute of Public Policy Studies, but one of his more
interesting methods was the use of the genetic algorithms of John
Holland (also of the U of Mich) to breed automata to have improved
strategies for playing Prisoner's dilemma. A one-sentence summary of
his results is that cooperation can displace non-cooperation if
individuals remember each other's behavior and have a high enough
probability of meeting again. An intermediate-length summary can be
found in Science _211_ (27 Mar 81) 1390-1396.

Subject: definition of common sense
I had a discussion with a friend on this exact topic just a few weeks
ago. My conclusions can be phrased as an elaboration of V. Pratt's
two criteria.
1. common knowledge basis (all facts depended on must be
common knowledge)
I think the (abstract) common knowledge basis can be more concretely
described as "cultural background". Your Formico's Pizza example
shows clearly that anybody not familiar with San Francisco will not
have the "common sense" to go there. The term "cultural background"
admits many levels of interpretation (national, provincial, etc.)
so most of REALLY COMMON knowledge basis will be encompassed.
2. low computational complexity (easy to check the conclusion).
I think the key here is not the checking (NP), but the finding (P) of
the solution. So here I differ from Vaughan, in that I believe common
sense is something "obvious" to a lot of people, by their own
reasoning power.
There are two factors involved: the first is the amount of reasoning
power; the second is the amount of deductive processing involved. On
the first factor, unfortunately usual words to describe people with
the adequate reasoning power such as "sensible", "reasonable", and
"objective" have also the connotation of being "emotionless". Let's
leave out the emotional aspects and use the term "reasonable" to
include everybody who is able to apply elementary logic to normal
situations. On the second factor, typical words to picture easy
deductive efforts are "obvious", "clear", and "evident".
So my definition of common sense is: that which is obvious to a
reasonable person with an adequate cultural background.
I should point out that the three parameters of common sense, cultural
background, reasoning power, and deductive effort, vary from place to
place and from person to person. If we agreed more on each other's
common sense, it might be easier to negotiate peace.

Subject: Analogy Bibliography
[Someone asked for an analogy bibliography a while back. This was compiled
about two years (maybe more) ago so it's partial and somewhat out of date,
but might serve as a starter for people interested in the topic. I've added
a couple of thing just now in looking it over. The focus is primarily
psychological, but readers will recognize some of the principle AI work as
well. I've got annotations for quite a few of these, but the remarks are
quite long and detailed so I won't burden AIList with them. -- Jeff]

What: Evaluating Expert Forecasts
Abstract: Probabilistic forecasts, often generated by an expert,
are critical to many decision aids and expert systems.
The quality of such inputs has usually been evaluated in
terms of logical consistency. However, in terms of
real-world implications, the external correspondence of
probabilistic forecasts is usually much more important
than internal consistency. I will discuss recently
developed procedures for evaluating external correspondence
and present research on the topic.
