Class AntiClusterWeighing

java.lang.Object
  net.sourceforge.cilib.moo.archive.solutionweighing.AntiClusterWeighing

All Implemented Interfaces:

Serializable, SolutionWeighing, Cloneable, Weighing<OptimisationSolution>

public class AntiClusterWeighing
extends Object
implements SolutionWeighing

An implementation of SolutionWeighing that weighs a collection of OptimisationSolutions based on how closely clustered these solutions are to one another.

This class can be used to select the most closely clustered optimisation solutions to be removed from the Archive if it reaches its maximum capacity. However, by selecting the least closely clustered solutions, you have a collection of solutions that are good candidates to be used as guides in a Multi-objective optimisation algorithm (see GuideSelectionStrategy).

Method Detail

getClone

public AntiClusterWeighing getClone()

Description copied from interface: Weighing

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 SolutionWeighing

Specified by:

getClone in interface Cloneable

Specified by:

getClone in interface Weighing<OptimisationSolution>

Returns:

An exact clone of the current object instance.

weigh

public boolean weigh(List<Selection.Entry<OptimisationSolution>> solutions)

Description copied from interface: Weighing

Perform a weighing on the provided list of entries.

Specified by:

weigh in interface SolutionWeighing

Specified by:

weigh in interface Weighing<OptimisationSolution>

Parameters:

solutions - The entries to weigh.

Returns:

true if successful, false otherwise.
