Class ParetoObjectiveComparator

java.lang.Object
  org.moeaframework.core.comparator.ParetoObjectiveComparator

All Implemented Interfaces:

Serializable, DominanceComparator

public class ParetoObjectiveComparator
extends Object
implements DominanceComparator, Serializable

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.
