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:

Serializable, CrossoverOperator<S>, Operator<List<S>,List<S>>

public class NullCrossover<S extends Solution<?>>
extends 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.
