When I evaluate the ANNs in 3-3s-4n-perf.sc, all 20 of them yield a perfect fitness rating! I've dumped the weights and I can see that all of them are unique. If its true, then I need to test all ANNs for reducibility, not just the first one in the file.
Time for a reality check - is my code working? I fed it 3-3s-4n-8743.sc and it rejected every ANN (as expected.) There could be an infinitude of 4 neuron ANNs that solve the 3-3s problem. I'm proceeding to the reduction code now. Dave ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
