I'm just starting to do some research into GAs, and I've read numerous papers. However, I think some actual simple algorithms would help my understanding a lot. Does anyone know of any actual algorithms that are publicly available? Thanks, Gavin Steyn steyn@eniac.seas.upenn.edu

My only real source for basic information on genetic algorithms has been the April '91 issue of Dr. Dobbs, some old AI-EXPERT's, and a book that I'm ordering (_Genetic Algorithms in Searching, Optinization and Machine Learning_ by Goldberg [Addison-Wesley]). Can anyone deliver any additional pointers? I am working on a research contract in which we'll have to apply some genetic algorithms. I HATE reinventing the wheel when someone has a better algorithm.

Here you have a copy of a post of its release and of how you can get it. ---------- cut here -------------------------------------- Date: Wed, 12 Sep 90 10:49:39 PDT From: schraudo%cs@ucsd.edu (Nici Schraudolph) Subject: release announcement: GENESIS 1.1ucsd I am pleased to announce the release of GENESIS 1.1ucsd, a heavily modified and enhanced version of the original genetic algorithm simulator by John J. Grefenstette. New features (since 1.0ucsd) include: - support of subdirectory structure for I/O files - application-specific parameters to the evaluation function - sigma scaling (a more robust alternative to window scaling) - stochastic decoding for searching continuous spaces - super-uniform population initialization option - support of Dynamic Parameter Encoding - cf. recent TR announcement Other major differences to standard GENESIS include the ability to use suitable C functions directly as evaluation functions, and to distribute a set of simulations to remote hosts. GENESIS 1.1ucsd can be obtained via anonymous ftp from the Artificial Life archive server as follows: % mkdir GAucsd % cd GAucsd % ftp iuvax.cs.indiana.edu (129.79.254.192) Login: anonymous Password: <anything> ftp> cd pub/alife/software/unix/GAucsd ftp> binary ftp> get GENESIS.1.Z ftp> get GENESIS.2.Z ftp> get GENESIS.3.Z ftp> get GENESIS.4.Z ftp> quit % uncompress GENESIS.?.Z % chmod +x GENESIS.? % GENESIS.1 % GENESIS.2 % GENESIS.3 % GENESIS.4 % lpr UsersGuide % view README A tech report describing the main new feature, Dynamic Parameter Encoding, is available in pub/alife/papers/schrau90-dpe.ps.Z on the same ftp server. If you don't have ftp access, I can honor requests for an e-mail copy of the source code. I maintain a mailing list for bug reports, updates, and other issues pertaining to this simulator - send me a message if you wish to be added to this list. Please feel free to send me your comments, suggestions and experiences regards 1.1ucsd. I have compiled and tested the code on Sun3, Sun4, Vax, Mips and Pyramid architectures - if you are installing 1.1ucsd on another system I'd like to hear whether you had any compatibility problems.

Below is the access info to the GENESIS program, a public domain GA
implementaion (not a classifier). You may also subscribe to the GA
mailing list by sending mail to GA-List-Request@AIC.NRL.NAVY.MIL.
Finally, Dave Goldberg's book has the pascal source code for
implementing a GA and Classifier system.
