  • Constructor Details

    • AbstractListChromosome

      public AbstractListChromosome(List<T> representation) throws InvalidRepresentationException
      Constructor, copying the input representation.
      Parameters:
      representation - inner representation of the chromosome
      Throws:
      InvalidRepresentationException - iff the representation can not represent a valid chromosome

    • AbstractListChromosome

      public AbstractListChromosome(T[] representation) throws InvalidRepresentationException
      Constructor, copying the input representation.
      Parameters:
      representation - inner representation of the chromosome
      Throws:
      InvalidRepresentationException - iff the representation can not represent a valid chromosome

    • AbstractListChromosome

      public AbstractListChromosome(List<T> representation, boolean copyList)
      Constructor.
      Parameters:
      representation - inner representation of the chromosome
      copyList - if true, the representation will be copied, otherwise it will be referenced.

  • Method Details

    • checkValidity

      protected abstract void checkValidity(List<T> chromosomeRepresentation) throws InvalidRepresentationException
      Asserts that representation can represent a valid chromosome.
      Parameters:
      chromosomeRepresentation - representation of the chromosome
      Throws:
      InvalidRepresentationException - iff the representation can not represent a valid chromosome

    • getRepresentation

      protected List<T> getRepresentation()
      Returns the (immutable) inner representation of the chromosome.
      Returns:
      the representation of the chromosome

    • getLength

      public int getLength()
      Returns the length of the chromosome.
      Returns:
      the length of the chromosome

    • newFixedLengthChromosome

      public abstract AbstractListChromosome<T> newFixedLengthChromosome(List<T> chromosomeRepresentation)
      Creates a new instance of the same class as this is, with a given arrayRepresentation. This is needed in crossover and mutation operators, where we need a new instance of the same class, but with different array representation.

      Usually, this method just calls a constructor of the class.

      Parameters:
      chromosomeRepresentation - the inner array representation of the new chromosome.
      Returns:
      new instance extended from FixedLengthChromosome with the given arrayRepresentation

    • toString

      public String toString()
      Overrides:
      toString in class Object
