Class DataSetBasedPositionInitialisationStrategy

java.lang.Object
  net.sourceforge.cilib.pso.particle.initialisation.DataSetBasedPositionInitialisationStrategy

All Implemented Interfaces:

Serializable, PositionInitialisationStrategy, Cloneable

public class DataSetBasedPositionInitialisationStrategy
extends Object
implements PositionInitialisationStrategy

This strategy initializes the position as well as the best position of a Particle using the DataSetBasedCentroidsInitialisationStrategy. The particle is therefore initialized from the current dataset. The dataset is found using the ClusteringUtils.getClusterableDataSet() method. The ClusteringProblem is also found using the ClusteringUtils.getClusteringProblem() method.

Method Detail

getClone

public DataSetBasedPositionInitialisationStrategy getClone()

Description copied from interface: Cloneable

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 PositionInitialisationStrategy

Specified by:

getClone in interface Cloneable

Returns:

An exact clone of the current object instance.

initialise

public void initialise(Particle particle,
                       OptimisationProblem problem)

Initialize the position and best position of the given Particle from the current dataset using the DataSetBasedCentroidsInitialisationStrategy.

Specified by:

initialise in interface PositionInitialisationStrategy

Parameters:

particle - the Particle that should be initialized

problem - the OptimisationProblem that is currently being optimized. This should be a ClusteringProblem, but is ignored, because the clustering problem is found via the ClusteringUtils.getClusteringProblem() method.
