Dear All, There's another open source GEP library released under the GNU. Its owner is Ryan O'Neil, a graduate student from George Mason University. In his words, "PyGEP is a simple library suitable for academic study of Gene Expression Programming in Python 2.5, aiming for ease of use and rapid implementation. It provides standard multigenic chromosomes; a population class using elitism and fitness scaling for selection; mutation, crossover and transposition operators; and some standard GEP functions and linkers." PyGEP is hosted at:
http://code.google.com/p/pygep/ It looks really nice and a good GEP implementation and Ryan seems to be working really hard to maintain and improve it. So please go take a look and join the project.
