extends Mutator<G,C>

The GaussianMutator class performs the mutation of a NumericGene. This mutator picks a new value based on a Gaussian distribution around the current value of the gene. The variance of the new value (before clipping to the allowed gene range) will be

The new value will be cropped to the gene's boundaries.
