public DifferentialEvolutionExponentialCrossover()

Method Detail

getClone

public DifferentialEvolutionExponentialCrossover getClone()

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 Operator

Specified by:

getClone in interface Cloneable

Specified by:

getClone in class CrossoverStrategy

Returns:

An exact clone of the current object instance.

Object.clone()

crossover

public List<Entity> crossover(List<Entity> parentCollection)

Perform the cross-over based on the exponential method for recombination. The given parentCollection should only contain two Entity objects, as the crossover operator is only defined for two Entitys.

It is VERY important that the order in which the parents are presented is consistent. The first Entity within the collection MUST be the trialVector Entity, followed by the target parent Entity.

Specified by:

crossover in class CrossoverStrategy

Returns:

A list consisting of the offspring. This operator only returns a single offspring Entity.

Throws:

UnsupportedOperationException - if the number of parents does not equal the size value of 2.

performOperation

public void performOperation(TopologyHolder holder)

Perform the operator operation given the current TopologyHolder.

Parameters:

holder - The TopologyHolder representing the required Topology instances.
