Class DominanceRanking<S extends Solution<?>>

java.lang.Object

org.uma.jmetal.util.solutionattribute.impl.GenericSolutionAttribute<S,Integer>

org.uma.jmetal.util.solutionattribute.impl.DominanceRanking<S>

All Implemented Interfaces:

Serializable, Ranking<S>, SolutionAttribute<S,Integer>

public class DominanceRanking<S extends Solution<?>>
extends GenericSolutionAttribute<S,Integer>
implements Ranking<S>

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.
