Interface GenerationEventListener<T extends Chromosome>

Type Parameters:

T - extends Chromosome

All Known Implementing Classes:

PatternProblem

public interface GenerationEventListener<T extends Chromosome>

A listener of the genetic algorithm generation event. Such a listener is notified after a generation step is executed.

A GenerationEventListener is registered to the algorithm by the method GeneticAlgorithm.addGenerationEventListener(GenerationEventListener). The listener is removed by invoking the method GeneticAlgorithm.removeGenerationEventListener(GenerationEventListener).

A GenerationEventListener can be registered to multiple different algorithms, thus being notified by all of them.

Another way to get notified of algorithms events is to override method GeneticAlgorithm.onGeneration(long) when subclassing the GeneticAlgorithm class.
