Method Detail

calculateFitness

public double calculateFitness()

Specified by:

calculateFitness in class ClusteringFitnessFunction

getClone

public KHarmonicMeansFunction getClone()

Description copied from class: ContinuousFunction

Create a cloned copy of the current object and return it. In general the created copy will be a deep copy of the provided instance. As a result this operation an be quite expensive if used incorrectly.

Specified by:

getClone in interface Cloneable

Specified by:

getClone in class ClusteringFitnessFunction

Returns:

An exact clone of the current object instance.
