One of my other examples
is redoing one of the best nodes, Genetic Programming or breeding Perls
, using my module. This node uses bits of legal perl code like "$x += $y;" and "$y=$x;" to make up a long operation; the bits are breed and mutated such that the operation, when evals to a number, and the GA aims to make code that matched a given number. This is a much better GA example, since with a good operations set, there's numerous ways to calculate a given number.
The reason this JAPH one works is that I upped the mutation rate to 10%, such that when it's close but not at the solution, there's a good chance that that one character pertubation is the right one to lock in the right solution.
