I am a college student of NCTU in Taiwan .I am taking the computer
go as my graduation project .I am very interested in neural net ,and I
think maybe I can apply the neuron theory to this game.All the approaches
so far for the computer go is not powerful enough to comapre with man.And
my teacher said it a new trial to use the neural techinque in this field.
He also said he ever saw some reports about games in your Digest.I think
maybe you can send us some useful info for games by neuron.
Sincerely Yours

Subject: Response - Who am I ...
From: "Grzegorz Piotr Klebus" <klebus@ii.pw.edu.pl>
Date: Fri, 02 Apr 93 12:41:57 +0200
[[ Editor's Note: This was a self-introduction, but the greater
readership might be interested in helping out... -PM ]]
My name is Grzegorz P. Klebus and I am student of
Computer Science at Department of Electronics, Warsaw University
of Technology, Warsaw, Poland. Now I study on 8th semester. My
main field of interest is, in general, Artificial Intelligence,
but I am particularly involved in subsymbolic methods, such as
neural networks and genetic algorithms.
I heard of your digest from my friend who found
references to it in ARCHIE. I am very glad to receive the digest
- - it may help me in my work.
Now I am doing a project on CMAC network and its
applications. I would be grateful if someone could send me
references to materials on CMAC. As a matter of fact it is very
hard to get information about this network.
You can contact me via e-mail:
klebus@ii.pw.edu.pl
Thanks in advance,
Grzegorz P. Klebus

Subject: Very Fast Simulated Reannealing (VFSR) Netlib & Statlib updates
From: Lester Ingber <ingber@alumni.cco.caltech.edu>
Date: Sun, 04 Apr 93 13:29:34 -0800
Very Fast Simulated Reannealing (VFSR) Netlib & Statlib updates
To get on or off blind-copy VFSR e-mailings, just send
an e-mail to ingber@alumni.caltech.edu with your request.
________________________________________________________________________
VFSR is a robust algorithm for nonlinear optimization. Major changes
since it was made publicly available under the GNU Copyleft in Nov 92
include support for independent setting of scales of annealing of
parameters, extended documentation, and a new option novel to
optimization algorithms permitting VFSR to recursively optimize its own
Program Options for a given system. The unique latter capability
required a major rewriting of the code to pass only local
pointer-parameters in the vfsr module.
It should be noted that some people have generally criticized simulated
annealing algorithms as _not_ containing enough free parameters to
tune different complex systems. While VFSR has demonstrated that
it is surprisingly robust given its default parameters, it also is
capable of quite a bit of "tuning"; I put these parameters outside
the code, in a separate structure, to enable people so motivated to
be able to tune their optimizations of their systems.
Codes in Netlib and Statlib have been updated, replacing version 6.38.
NETLIB (compressed share file) version 9.3
Interactive:
ftp research.att.com
[login as netlib, your_login_name as password]
cd opt
binary
get vfsr.Z
Email:
mail netlib@research.att.com [AT&T Bell Labs, NJ, USA]
mail netlib@ornl.gov [Oak Ridge Natl Lab, TN, USA]
mail netlib@unix.hensa.ac.uk [U Kent, UK]
mail netlib@nac.no [Oslo, Norway]
mail netlib@cs.uow.edu.au [U Wollongong, NSW, Australia]
and send the one-line message
send vfsr from opt
(It may take a week or so for the code in research.att.com to propagate
to the other netlib sites.)
STATLIB (uncompressed share file) version 9.3
Interactive:
ftp lib.stat.cmu.edu
[login as statlib, your_login_name as password]
cd general
get vfsr
Email:
mail statlib@lib.stat.cmu.edu
and send the one-line message
send vfsr from general
(It may take a few days for the new version to be installed here.)
After getting the file, on your local machine:
ingber% uncompress vfsr.Z [If a compressed file was obtained]
ingber% sh vfsr
ingber% cd VFSR.DIR
The directory VFSR.DIR contains the code.
If you do not have ftp access, get information on the FTPmail service
by sending the word "help" as a message to ftpmail@decwrl.dec.com.
If you receive VFSR via e-mail, then first `uudecode mailfile',
(where mailfile may be a synthesis of several files) to get vfsr.Z,
and then follow the previous directions.
If this is not convenient, and if your mailer can handle large files,
I directly can send you the code or papers you require via e-mail.
Sorry, I cannot assume the task of mailing out hardcopies of code
or papers.

Subject: New Release -- Chipmunk Analog VLSI CAD Tools
From: John Lazzaro <lazzaro@boom.CS.Berkeley.EDU>
Date: Sun, 04 Apr 93 13:42:27 -0800
Caltech VLSI CAD Tool Distribution -- New Revision
---------------------------------------------------
We are offering to the Internet community a new revision of the
Caltech electronic CAD system for analog VLSI neural networks. This
distribution contains tools for schematic capture, netlist creation,
and analog and digital simulation (log), IC mask layout, extraction,
and DRC (wol), simple chip compilation (wolcomp), MOSIS fabrication
request generation (mosis), netlist comparison (netcmp), data plotting
(view) and postscript graphics editing (until). These tools were used
exclusively for the design and test of all the integrated circuits
described in Carver Mead's book "Analog VLSI and Neural Systems".
Until was used as the primary tool for figure creation for the book.
The distribution also contains an example of an analog VLSI chip that
was designed and fabricated with these tools, and an example of an
Actel field-programmable gate array design that was simulated and
converted to Actel format with these tools.
These tools are distributed under a license very similar to the GNU
license; the minor changes protect Caltech from liability.
Highlights of the new revision includes:
* Ports to new platforms (Supported platforms now include: Sun SPARC,
Sun 3, HP Series 300/400/700/800, DEC MIPS-based Ultrix, Appple AU/X,
linux, and IBM RS/6000 support).
* Support for black and white displays, and resource database support
for user preferences for sizing and placement of windows. New
display modes in analog to support small screens.
* Direct generation of SPICE netlists in analog, and new models
for floating-well FET's, two-terminal devices with arbitrary i-v
curves, and quantum-well tunnel diodes.
* Many bug fixes for analog, wol, view, and until, and new features for view.
If you are interested in some or all of these tools,
1) ftp to hobiecat.cs.caltech.edu on the Internet,
2) log in as anonymous and use your username as the password
3) cd pub/chipmunk
4) copy the file README, that contains more information.
European researchers can access these files through anonymous ftp
using the machine ifi.uio.no in Norway; the files are in the directory
chipmunk. We are unable to help users who do not have Internet ftp
access.

Subject: NN market size
From: Alexandre Wallyn <wallyn@capsogeti.fr>
Date: Tue, 06 Apr 93 18:59:12 +0100
You asked in Neuron Digest, volume 11, issue 21, for a prospective
evaluation of NN market size. I made a short compilation one month ago,
so here it is:
1) There is no specific "Neural networks market" which could be an
envelopp: this technology is pushed by the offer.
2) We can nevertheless take as a maximal market size both the KBS Market
tools (270 M$ in 1991, expected 370M$ according to Spang Robinson
report of 1992) or the whole Neural network and fuzzy technologies
market (estimated 300M$ in 1991, 580 M$ in 1992, with a prospective
annual rate of 65\%: lettre de l'IA, octobre 1992)
3) OVUM estimates the total European market for Knowledge Based software
and services at 500MEcus for 1992 and 1500MEcus for 1995. Such and
increase not only supposes a wider distribution of the technology, but
also requires pushing the limits of the technology itself. (1 Ecu =
1.2 $ for the moment)
4) Intelligent Software Strategies (march 1993) is much more pessimistic,
and consider the KBS market and NN market in reduction: KBS market
moves to the OO market, and NN market towards specialised products
(oriented to users), but there is no overall concrete evaluations (for
NNs) here.
I hope this helps, and welcome any comments and critics.

Subject: Genetic Request
From: 90700368@vax1.dcu.ie
Date: Tue, 13 Apr 93 10:45:00 +0000
Dear Sir,
I realise that your excellent publication may not be the correct forum
for this request but maybe you would kindly consider its submission
which would allow me to hopefully contact people who are bound to be
infinitely more knowledgeable than myself about a problem I am
encountering.
I have written a simple genetic algorithm somewhat like the one described
in Goldberg's book using breeding, mutation and crossover as operators.
The algorithm is being used to optimise a least squares error in order
to find the parameters of a mutlivariate expression. Unfortunately I am
finding that in a fixed population size that the population very rapidly
becomes dominated by a particular chromosome and as such there is not
enough diversity left in the genepool for a particularly good fitting
expression to be found. I have tried linear prescaling as described by
Goldberg but it appeared to me that it merely slowed down the whole
process rather than actually dealing with the problem. I have read a
couple of papers including the Federal Bureau of Mines report but it really
didn't seem to help.
Please, please has anyone come across a good way around the problem, if so
I would be absolutely ecstatic to hear from you. Just as an aside if you
do decide to contact me would you mind keeping the mathematical
content of your reply to a minimum.
Thank you in advance for your kind consideration and I hope this will
not cause you too much inconvenience.
