[Push] Artificial ant problem

[Lee Spector]

Pablo,

Push has been used for a lot of non-mathematical problems, but  
unfortunately there aren't very many cleaned up examples floating  
around, and I don't know of an artificial ant example... although it  
shouldn't be too hard to write.

In the Lisp version, at http://hampshire.edu/lspector/push3/, there  
are a couple of examples including the even n-parity problem (which is  
Boolean).

A much more complicated example, using Push but not PushGP per se, is  
the SwarmEvolve 2.0 system that comes as one of the demos with the  
breve simulation environment (from www.spiderland.org). This uses many  
types but it's more of an artificial life application than a GP  
application.

Your message is a reminder to me that we are interested in polishing  
up Jon Klein's new Java implementation called Psh (http://www.spiderland.org/Psh/ 
), and a good idea for that would be to code up some other standard  
problems like artificial ant. But I'm not sure when this will happen.

On the creation of additional types, I think this may also be easiest  
in Psh. Maarten Keijzer also has versions in which types can be  
defined dynamically by Push itself, or built automatically from Java  
types via reflection, but I don't know if he has made any of these  
publicly available (I'll cc him).
