Package org.uma.jmetal.util.neighborhood.impl

Class AdaptiveRandomNeighborhood<S>

java.lang.Object

org.uma.jmetal.util.neighborhood.impl.AdaptiveRandomNeighborhood<S>

All Implemented Interfaces:

Serializable, Neighborhood<S>

public class AdaptiveRandomNeighborhood<S>
extends Object
implements Neighborhood<S>

This class implements the adaptive random neighborhood (topology) defined by M. Clerc. Each solution in a solution list must have a neighborhood composed by it itself and K random selected neighbors (the same solution can be chosen several times).
