public class RSMutator<G extends Gene<?,G>,C extends Comparable<? super C>> extends Mutator<G,C>
The reverse sequence mutation, two positions i and j are randomly chosen The gene order in a chromosome will then be reversed between this two points. This mutation operator can also be used for combinatorial problems, where no duplicated genes within a chromosome are allowed, e.g. for the TSP.- Since:
