br.otimizes.oplatool.core.jmetal4.qualityIndicator.GeneralizedSpread

public class GeneralizedSpread
extends java.lang.Object

This class implements the generalized spread metric for two or more dimensions. It can be used also as command line program just by typing. $ java br.otimizes.oplatool.core.jmetal4.qualityIndicator.GeneralizedSpread Reference: A. Zhou, Y. Jin, Q. Zhang, B. Sendhoff, and E.

public double generalizedSpread(double[][] paretoFront,
                                double[][] paretoTrueFront,
                                int numberOfObjectives)

Calculates the generalized spread metric. Given the pareto front, the true pareto front as double [] and the number of objectives, the method return the value for the metric.

Parameters:

paretoFront - The pareto front.

paretoTrueFront - The true pareto front.

numberOfObjectives - The number of objectives.

Returns:

the value of the generalized spread metric
