Class Hypervolume<Evaluate extends List<? extends Solution<?>>>

java.lang.Object

org.uma.jmetal.util.naming.impl.SimpleDescribedEntity

org.uma.jmetal.qualityindicator.impl.Hypervolume<Evaluate>

All Implemented Interfaces:

QualityIndicator<Evaluate,Double>, DescribedEntity

public class Hypervolume<Evaluate extends List<? extends Solution<?>>>
extends SimpleDescribedEntity
implements QualityIndicator<Evaluate,Double>

This class implements the hypervolume indicator. The code is the a Java version of the original metric implementation by Eckart Zitzler. Reference: E. Zitzler and L.
