  • Method Details

    • getG

      public int getG()
      Gets the generation when the Individual was created.
      Returns:
      the generation when the Individual was created.

    • getGenotype

      public double[] getGenotype()
      Gets a reference to the Individual genotype.
      Returns:
      the Individual genotype.

    • getFitness
