public class EpsilonHelper
extends Object

Provides ε values for algorithms using ε-dominance archives on the standard test problems.

Method Summary

Method Detail

getEpsilon

public static double getEpsilon(Problem problem)

Returns the ε value used for the standard problems in sensitivity analysis. If the problem is not recognized, the default ε value of 0.01 is returned.

Parameters:

problem - the problem

Returns:

the ε value used for the standard problems in sensitivity analysis

convert

public static EpsilonBoxDominanceArchive convert(Population population,
                                                 double[] epsilon)

Converts the population to an EpsilonBoxDominanceArchive with the given ε values. To prevent unnecessary computations, this conversion only occurs if the original population is not an EpsilonBoxDominanceArchive and does not have matching ε values.

Parameters:

population - the population to convert

epsilon - the ε values

Returns:

the population converted to an EpsilonBoxDominanceArchive with the given ε values
