java.lang.Object

org.uma.jmetal.util.comparator.EqualSolutionsComparator<S>

All Implemented Interfaces:

Comparator<S>

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

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.

Method Detail

compare

public int compare(S object1,
                   S object2)

Compares two solutions.

Specified by:

compare in interface Comparator<S extends Solution<?>>

Parameters:

object1 - Object representing the first Solution.

object2 - Object representing the second Solution.

Returns:

-1, or 0, or 1, or 2 if solution1 is dominates solution2, solution1 and solution2 are equals, or solution1 is greater than solution2, respectively.
