MOOptimisationProblem

public MOOptimisationProblem()

MOOptimisationProblem

public MOOptimisationProblem(MOOptimisationProblem copy)

Method Detail

getClone

public MOOptimisationProblem getClone()

Description copied from interface: OptimisationProblem

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 OptimisationProblem

Specified by:

getClone in interface Problem

Specified by:

getClone in interface Cloneable

Returns:

An exact clone of the current object instance.

See Also:

Object.clone()

getFitness

public MOFitness getFitness(Type[] solutions,
                            boolean count)

getFitness

public MOFitness getFitness(Type solution,
                            boolean count)

Description copied from interface: OptimisationProblem

Returns the fitness of a potential solution to this problem. The solution object is described by the domain of this problem, see OptimisationProblem.getDomain(). An instance of InferiorFitness should be returned if the solution falls outside the search space of this problem.

Specified by:

getFitness in interface OptimisationProblem

Parameters:

solution - The potential solution found by the optimisation algorithm.

count - True if this call should contribute to the fitness evaluation count, see OptimisationProblem.getFitnessEvaluations().

Returns:

The fitness of the solution.

getFitness

public Fitness getFitness(int index,
                          Type solution,
                          boolean count)

getFitnessEvaluations

public int getFitnessEvaluations()

Description copied from interface: OptimisationProblem

Returns the number of times the underlying fitness function has been evaluated.

Specified by:

getFitnessEvaluations in interface OptimisationProblem

Returns:

The number fitness evaluations.

getDomain

public DomainRegistry getDomain()

Description copied from interface: OptimisationProblem

Returns the domain component that describes the search space for this problem.

Specified by:

getDomain in interface OptimisationProblem

Returns:

A DomainRegistry object representing the search space.

getBehaviouralDomain

public DomainRegistry getBehaviouralDomain()

Description copied from interface: OptimisationProblem

Returns the domain component that describes the search space of the needed behavioral characteristics of the problem. This is mainly used for ECs, however, the use of behavioral parameters with PSO will be investigated.

Specified by:

getBehaviouralDomain in interface OptimisationProblem

Returns:

The domain of the behavioral component

getDataSetBuilder

public DataSetBuilder getDataSetBuilder()

Description copied from interface: OptimisationProblem

Get the associated DataSetBuilder.

Specified by:

getDataSetBuilder in interface OptimisationProblem

Returns:

The currently associated DataSetBuilder.

setDataSetBuilder

public void setDataSetBuilder(DataSetBuilder dataSetBuilder)

Description copied from interface: OptimisationProblem

Set the DataSetBuilder for this optimistion problem.

Specified by:

setDataSetBuilder in interface OptimisationProblem

Parameters:

dataSetBuilder - The DataSetBuilder to be set on the current OptimisationProblem.

accept

public void accept(ProblemVisitor visitor)

Description copied from interface: OptimisationProblem

Accept the provided Visitor and perform the Visitor.visit(Object) method.

Specified by:

accept in interface OptimisationProblem

Parameters:

visitor - The visitor which has operations to perform.
