Constructor Details

AdditiveEpsilonIndicator

public AdditiveEpsilonIndicator(Problem problem,
 NondominatedPopulation referenceSet)

Constructs an additive ε-indicator evaluator for the specified problem and corresponding reference set. The default normalization procedure, as specified by DefaultNormalizer, is used.

Parameters:

problem - the problem

referenceSet - the reference set for the problem

AdditiveEpsilonIndicator

public AdditiveEpsilonIndicator(Problem problem,
 NondominatedPopulation referenceSet,
 Normalizer normalizer)

Constructs an additive ε-indicator evaluator with a user-provided normalizer.

Parameters:

problem - the problem

referenceSet - the reference set for the problem

normalizer - the user-provided normalizer, or null if the default is used

Method Details

evaluate

public double evaluate(NondominatedPopulation approximationSet)

Description copied from interface: Indicator

Returns the value of this unary quality indicator given the specified non-dominated population.

Parameters:

approximationSet - the non-dominated population to be evaluated

Returns:

the value of this quality indicator given the specified non-dominated population
