public class GaussianMutator<G extends NumericGene<?,G>,C extends Comparable<? super C>>
extends SamplerMutator<G,C>

The GaussianMutator class performs the mutation of a NumericGene. This mutator picks a new value based on a Gaussian distribution, defined by the GaussianMutator.Shape parameter of the mutator.

Since:

1.0

Version:

8.3
