  com.rapidminer.tools.math.optimization.ec.es.GaussianMutation

All Implemented Interfaces:

Mutation, PopulationOperator

public class GaussianMutation
extends java.lang.Object
implements Mutation

Changes the values by adding a gaussian distribution multiplied with the current variance. Clips the value range to [min,max].
