Type Parameters:

T - The class of chromosomes to work with.

public class SimpleMutator<T extends Chromosome>
extends Mutator<T>

A simple mutation operator. It performes the simplest mutation algorithm according to a specified probability. A chromosome position is randomly chosen and its gene randomized.
