java.lang.Object

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

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

All Implemented Interfaces:

java.io.Serializable, java.util.Comparator<S>

public class EpsilonDominanceComparator<S extends Solution<?>>
extends DominanceComparator<S>

This class implements a solution comparator taking into account the violation constraints and an optional epsilon value (i.e, implements an epsilon dominance comparator)

Method Details

compare

public int compare(S solution1, S solution2)

Compares two solutions.

Specified by:

compare in interface java.util.Comparator<S extends Solution<?>>

Overrides:

compare in class DominanceComparator<S extends Solution<?>>

Parameters:

solution1 - Object representing the first Solution.

solution2 - Object representing the second Solution.

Returns:

-1, or 0, or 1 if solution1 dominates solution2, both are non-dominated, or solution1 is dominated by solution2, respectively.
