A GA doesn't evaluate a trial solution so much as applies the solution to generate a fitness score. Higher scores are either more likely or guaranteed a shot at reproducing in the next round. It's the whole genetic code rather than the mutation, that reproduces. > Also, I wonder how many times in Darwinial evolution a species evolved a > truely quantum leap in it's genetics, only to be wiped out by a flood or > volcanic explosion, os simply got eaten by it's predator. :-) > > You get real world opportunism. I had a parameter backwards, and the algorithm stabilized at a negative price in an economic simulation--which was, in fact, the correct but unanticipated result. Ashlock was evolving simple code, and put in a random result as the penalty for not reaching the end of the decision tree--and they adapted to use that "hazard" as a synchronization mechanism to boost their scores. . .
