All Implemented Interfaces:

ExampleSetBasedPopulationOperator

public class FourierGeneratingMutation
extends ExampleSetBasedIndividualOperator

The mutation operator for FourierGGA. This operator adds single attributes from the original set, creates new ones and deselect single attributes. For each freshly added attribute a fourier generation will will be performed.
