Constructor Detail

PopulationUniqueness

public PopulationUniqueness(double riskThreshold,
                            ARXPopulationModel populationModel)

Creates a new instance of this criterion. Uses Dankar's method for estimating population uniqueness. This constructor will clone the population model, making further changes to it will not influence the results. The default accuracy is 10e-6 and the default maximal number of iterations is 1000.

Parameters:

riskThreshold -

populationModel -

PopulationUniqueness

public PopulationUniqueness(double riskThreshold,
                            ARXPopulationModel populationModel,
                            ARXSolverConfiguration config)

Creates a new instance of this criterion. Uses Dankar's method for estimating population uniqueness. This constructor will clone the population model, making further changes to it will not influence the results.

Parameters:

riskThreshold -

populationModel -

config -
