Re: classifier system routines

[Rick Riolo]

Hi,
CFS-C certainly is not still state of the art, neither
implementation-wise nor conceptual-wise!
(After all, its over 12 years old...when I wrote it
the ansi-c standards were not yet in place, and various
compilers on pc's and mac's had strange limits on heap
sizes, variable name lengths, etc!)

We have implemented an alpha version CFS-S in Swarm.
You can get a version (which works under some earlier Swarm version,
eg 1.0 or so...I can't recall right now) 
at the PSCS website:
  http://www.pscs.umich.edu/Software/Contents.html

This implements all that we still thought might be useful
in CFS-C, plus some new features and with plans
to make it easy to implement some of the features
in other (non-public) systems, eg Stewart Wilson's
macro classifiers.

Please feel free to download this alpha version and give it
a try.  Feedback is welcome.   I hope to get someone
to work on it in the next year sometime, to
a) get it up to the latest swarm
b) find and squash bugs
c) implement new features (eg macro classifiers)

- r

ps By the way there are newer non-swarm classifier
   systems in the public domain, which I believe you can
   find at the various Encore archives, eg, two offspring
   of the original CFS-C, and Tolkien, a C++ based system.
   There might be others as well, I'm not sure.
