- Larry Yaegar (sorry if I butchered the last name!) at apple (larryy@apple.com
- is his address if memory serves) has a wonderful simulation that runs on
- SGI machines. It falls most squarely under the category of Artificial Life,
- since the evolving creatures are implicitly rewarded for survival and
- reproduction (i.e., they must feed, defend themselves, and mate while others
- around them do the same) rather than being rewarded for an explicit externally
- imposed fitness function. Different genotypes evolve, each with their own
- niche. Most go extinct fairly rapidly, some flourish. Very visual, this work
- will probably be published in the forthcoming Artificial Life III procedings
- and the software can be obtained from Larry Yaegar (I think).
-
- On a less visual (but more supervised) note John Koza and James Rice have
- done work with emergent behavior of ants (see ALife-2 proceedings & video, and
- JK's new book "Genetic Programming," and the accompanying video by Koza &
- Rice.). Also see work by Collins & Jefferson (also in ALife3) and Rob Collins
- dissertation, available via ftp from UCLA/cognet.
