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

java.lang.Object

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

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

All Implemented Interfaces:

Serializable, QualityIndicator<Evaluate,Double>, DescribedEntity

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

The Error Ratio (ER) quality indicator reports the ratio of solutions in a front of points that are not members of the true Pareto front. NOTE: the indicator merely checks if the solutions in the front are not members of the second front. No assumption is made about the second front is a true Pareto front, i.e, the front could contain solutions that dominate some of those of the supposed Pareto front. It is a responsibility of the caller to ensure that this does not happen.
