Class FrequencySelectionMutationBasedPerturbation

java.lang.Object

org.uma.jmetal.component.catalogue.pso.perturbation.impl.FrequencySelectionMutationBasedPerturbation

All Implemented Interfaces:

Perturbation

public class FrequencySelectionMutationBasedPerturbation
extends Object
implements Perturbation

This perturbation applies a mutation operator to a fixed set of solutions according to a frequency parameter. Given a frequency of application parameter f and a list of solutions, the mutation will be applied to solutions in position p such as p % f == 0.
