public class WeaselMutator<G extends Gene<?,G>,C extends Comparable<? super C>> extends Mutator<G,C>
Mutator implementation which is part of the Weasel program algorithm. The Weasel program is a thought experiment by Richard Dawkins to illustrate the functioning of the evolution: random mutation combined with non-random cumulative selection.

The mutator mutates the genes of every chromosome of every genotype in the population with the given mutation probability.

Engine setup for the Weasel program:
final Engine<CharacterGene, Integer> engine = Engine.builder(problem) // Set the 'WeaselSelector'. .selector(new WeaselSelector<>()) // Disable survivors selector. .offspringFraction(1) // Set the 'WeaselMutator'. .alterers(new WeaselMutator<>(0.05)) .build();
