Method Detail

step

public void step()

Description copied from interface: GA

Do one step. This could create a new generation (generation-based GA) or do one reproduction (steady state).

doReproduction

private IndividualList<T> doReproduction()

Selects two individuals, recombines and mutates them.

Returns:

A list of two offsprings.

Since:

11.08.2012

newIndividualRequested

public void newIndividualRequested()

Description copied from interface: EvaluationListener

This will be notified when a evaluator demands a new individual for evaluation.

individualEvaluated

public void individualEvaluated(T ind)

Description copied from interface: EvaluationListener

This will be notified when an evaluator has evaluated the individual.

Parameters:

ind - The individual that has been evaluated.
