The NEAT software is based on the NeuroEvolution of Augmenting Topologies
method of evolving artificial neural networks, by Stanley and
Miikkulainen (2001). Papers describing the method and some associated
findings are available at:

This package is currently in an alpha state. The implementation should be

There are also lots of extra features left to be added from the various papers
published about this method.
