Class DominanceRanking

java.lang.Object

org.uma.jmetal.util.solutionattribute.impl.DominanceRanking

All Implemented Interfaces:

Ranking<Solution>, SolutionAttribute<Solution,Integer>

public class DominanceRanking
extends Object
implements Ranking<Solution>

This class implements some facilities for ranking set of solutions. Given a collection of solutions, they are ranked according to scheme 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 solutions after removing those belonging to subset 0, and so on.
