Class EvolutionaryStrategy

+
+
+ +
+
    +
  • +
    +
    Direct Known Subclasses:
    +
    MuPlusLambda, TournamentSelection
    +
    +
    +
    +
    public abstract class EvolutionaryStrategy
+extends Module
    +
    This class specifies the characteristics of an evolutionary strategy. The evolutionary + strategy's job is to generate the next population of solutions. In JCGP this is done by modifying + the provided population object rather than creating a new one. +

    + A typical implementation of EvolutionaryStratey iterates through the chromosomes + in the population and selects the individual(s) to be promoted. It then uses + mutator.mutate() to generically mutate the promoted individual(s). Parameter-dependent + strategies can be implemented by accessing the parameters via the resources + argument. +

    + Parameters may be specified to control the implemented strategy. Any parameters + registered with registerParameters() should be displayed by the user interface, + if it is being used. See Module for more information. +

    + It is advisable to use Resources.reportln() and Resources.report() + to print any relevant information. Note that reportln() and report() are affected + by the report interval base parameter. Use Resources.println() and + Resources.print() to print information regardless of the current generation. + See Resources for more information.

Class MuPlusLambda

+ +
+
    +
  • +
    +
    +
    public class MuPlusLambda
+extends EvolutionaryStrategy
    +
    (μ + λ)-ES +

    + This strategy selects the μ fittest chromosomes from the population. + The promoted individuals are copied into the new population and mutated + λ times, but also carried forward unchanged. The total population size + is μ + λ. +

    + Two integer parameters are used to control this strategy: parents + and offspring. They are constrained in that they must always add up to + the population size, and must never be smaller than 1. +
    + One additional parameter, report, controls whether a detailed log of the + algorithm's operation is to be printed or not. Reports respect the report + interval base parameter.

Class TournamentSelection

+
+
+ +
+
    +
  • +
    +
    +
    public class TournamentSelection
+extends EvolutionaryStrategy
    +
    Tournament selection +

    + This strategy generates a new population by selecting a specified number + of chromosomes from the original population and selecting the fittest out + of the isolated subset (the tournament). The selected individual is mutated + using the specified mutator. This process is repeated until the new population + is complete. +

    + One integer parameter is used to control this strategy: tournament + size. This must always be greater than 0 and smaller than or equal to the + population size. Setting it to equal population size results in the same + chromosome being selected for every tournament, and setting it to 1 leads + to an effectively random search. +
    + One additional parameter, report, controls whether a detailed log of the + algorithm's operation is to be printed or not. Reports respect the report + interval base parameter.
