Method Detail

getClone

public abstract EnvironmentChangeResponseStrategy<E> getClone()

Clone the EnvironmentChangeResponseStrategy object.

Specified by:

getClone in interface Cloneable

Returns:

A cloned EnvironmentChangeResponseStrategy

See Also:

Object.clone()

respond

public void respond(E algorithm)

Respond to the environment change and ensure that the neighbourhood best entities are updated. This method (Template Method) calls two other methods in turn:

• performReaction(PopulationBasedAlgorithm)
• updateNeighbourhoodBestEntities(Topology)

Parameters:

algorithm - some population based algorithm

performReaction

protected abstract void performReaction(E algorithm)

This is the method responsible for responding that should be overridden by sub-classes.

Parameters:

algorithm -

updateNeighbourhoodBestEntities

protected void updateNeighbourhoodBestEntities(Topology<? extends Entity> topology)

TODO: The problem with this is that it is PSO specific. It uses particles instead of entities, because the Entity class does not have the notion of a neighbourhood best.

Parameters:

topology - a topology of particles :-(

getHasMemory

public boolean getHasMemory()

setHasMemory

public void setHasMemory(boolean hasMemory)
