Class InterClusterDistance

      net.sourceforge.cilib.functions.ContinuousFunction
          net.sourceforge.cilib.functions.clustering.ClusteringFitnessFunction
              net.sourceforge.cilib.functions.clustering.InterClusterDistance

All Implemented Interfaces:

Serializable, Cloneable

public class InterClusterDistance
extends ClusteringFitnessFunction

This clustering fitness function will probably never be used to train on directly. The main reason why it has been implemented is to be able to take measurements of the inter-cluster distance via the GenericFunctionMeasurement class. NOTE: By default, the cluster center refers to the cluster centroid. See ClusterCenterStrategy.

Method Detail

calculateFitness

public double calculateFitness()

Specified by:

calculateFitness in class ClusteringFitnessFunction

getClone

public InterClusterDistance 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.
