All Implemented Interfaces:

Serializable, Comparator<S>

public class EqualSolutionsComparator<S extends Solution<?>>
extends Object
implements Comparator<S>, Serializable

This class implements a Comparator (a method for comparing Solution objects) based whether all the objective values are equal or not. A dominance test is applied to decide about what solution is the best.
