Package org.uma.jmetal.operator.crossover.impl

Class NullCrossover<S extends Solution<?>>

java.lang.Object

org.uma.jmetal.operator.crossover.impl.NullCrossover<S>

All Implemented Interfaces:

java.io.Serializable, CrossoverOperator<S>, Operator<java.util.List<S>,java.util.List<S>>

public class NullCrossover<S extends Solution<?>>
extends java.lang.Object
implements CrossoverOperator<S>

This class defines a null crossover operator: the parent solutions are returned without any change. It can be useful when configuring a genetic algorithm and we want to use only mutation.
