About the 20 chromes per file, the examine program just reads the first chrome, and that is the best one. I'm pretty sure that's the way the 4Play code is, and it should be the same for waybak.
In 4play, we had hundreds of weights, and many could be eliminated. And the same for the dozens of neurons. Here, with only 4 neurons, I don't think it's possible to eliminate one, but there's a good chance to eliminate a few weights. m -- I'm proud of http://ANNEvolve.sourceforge.net.
