Interface SteadyStateStatisticsForm

All Known Implementing Classes:
HypervolumeStatistics, MultiObjectiveStatistics, SimpleStatistics
public interface SteadyStateStatisticsForm
This interface defines the hooks for SteadyStateEvolutionState objects to update themselves on. Note that the the only methods in common with the standard statistics are initialization and final. This is an optional interface: SteadyStateEvolutionState will complain, but will permit Statistics objects that don't adhere to it, though they will only have their initialization and final statistics methods called!

See SteadyStateEvolutionState for how regular Statistics objects' hook methods are called in steady state evolution.

  • Method Details

    • enteringInitialPopulationStatistics

      void enteringInitialPopulationStatistics(SteadyStateEvolutionState state)
      Called when we created an empty initial Population.

    • enteringSteadyStateStatistics

      void enteringSteadyStateStatistics(int subpop, SteadyStateEvolutionState state)
      Called when we have filled the initial population and are entering the steady state.

    • individualsBredStatistics

      void individualsBredStatistics(SteadyStateEvolutionState state, Individual[] individuals)
      Called each time new individuals are bred during the steady-state process.

    • individualsEvaluatedStatistics

      void individualsEvaluatedStatistics(SteadyStateEvolutionState state, Individual[] newIndividuals, Individual[] oldIndividuals, int[] subpopulations, int[] indices)
      Called each time new individuals are evaluated during the steady-state process, NOT including the initial generation's individuals.

    • generationBoundaryStatistics

      void generationBoundaryStatistics(EvolutionState state)
      Called when the generation count increments

    • preCheckpointStatistics

      void preCheckpointStatistics(EvolutionState state)
      Called immediately before checkpointing occurs.

    • postCheckpointStatistics

      void postCheckpointStatistics(EvolutionState state)
      Called immediately after checkpointing occurs.

    • prePreBreedingExchangeStatistics

      void prePreBreedingExchangeStatistics(EvolutionState state)
      Called immediately before the pre-breeding exchange occurs.

    • postPreBreedingExchangeStatistics

      void postPreBreedingExchangeStatistics(EvolutionState state)
      Called immediately after the pre-breeding exchange occurs.

    • prePostBreedingExchangeStatistics

      void prePostBreedingExchangeStatistics(EvolutionState state)
      Called immediately before the post-breeding exchange occurs.

    • postPostBreedingExchangeStatistics

      void postPostBreedingExchangeStatistics(EvolutionState state)
      Called immediately after the post-breeding exchange occurs.

    • finalStatistics

      void finalStatistics(EvolutionState state, int result)
      Called immediately after the run has completed. result is either state.R_FAILURE, indicating that an ideal individual was not found, or state.R_SUCCESS, indicating that an ideal individual was found.
