Interface Evolution<G extends Gene<?,G>,C extends Comparable<? super C>>

Type Parameters:
G - the gene type
C - the fitness result type
All Known Implementing Classes:
Engine
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface Evolution<G extends Gene<?,G>,C extends Comparable<? super C>>
This functional interface defines the evolution function, which takes an EvolutionStart object, evolves the population, and returns an EvolutionResult object.
Since:
5.1
Version:

    • evolve

      EvolutionResult<G,C> evolve(EvolutionStart<G,C> start)
      Perform one evolution step with the given evolution start object New phenotypes are created with the fitness function defined by this engine
      Parameters:
      start - the evolution start object
      Returns:
      the evolution result
      Throws:
      NullPointerException - if the given evolution start is null

      API Note:
      The implementation of this method must be thread-safe.

    • evolve

      default EvolutionResult<G,C> evolve(ISeq<Phenotype<G,C>> population, long generation)
      Perform one evolution step with the given population and generation.

      This method is thread-safe.

      Parameters:
      population - the population to evolve
      generation - the current generation; used for calculating the phenotype age.
      Returns:
      the evolution result
      Throws:
      NullPointerException - if the given population is null
      IllegalArgumentException - if the given generation is smaller then one
