Package org.moeaframework.core.comparator

Class ParetoObjectiveComparator

java.lang.Object

org.moeaframework.core.comparator.ParetoObjectiveComparator

All Implemented Interfaces:

DominanceComparator

public class ParetoObjectiveComparator
extends Object
implements DominanceComparator

Compares two solutions using the Pareto dominance relation on the objectives.

In general, the ParetoDominanceComparator should be used instead as it also incorporates constraint violation checks.

public int compare(Solution solution1,
 Solution solution2)

Description copied from interface: DominanceComparator

Compares the two solutions using a dominance relation, returning -1 if solution1 dominates solution2, 1 if solution2 dominates solution1, and 0 if the solutions are non-dominated.

Specified by:

compare in interface DominanceComparator

Parameters:

solution1 - the first solution

solution2 - the second solution

Returns:

-1 if solution1 dominates solution2, 1 if solution2 dominates solution1, and 0 if the solutions are non-dominated
