org.uma.jmetal.util.ranking.impl.MergeNonDominatedSortRanking<S>

All Implemented Interfaces:

Ranking<S>

public class MergeNonDominatedSortRanking<S extends Solution<?>>
extends Object
implements Ranking<S>

This class implements a solution list ranking based on dominance ranking. Given a collection of solutions, they are ranked according to scheme similar to the one proposed in NSGA-II. As an output, a set of subsets are obtained. The subsets are numbered starting from 0 (in NSGA-II, the numbering starts from 1); thus, subset 0 contains the non-dominated solutions, subset 1 contains the non-dominated population after removing those belonging to subset 0, and so on.
