Constructor Detail

### BinaryChromosome

    public BinaryChromosome(List<Integer> representation)

  Constructor.

  Parameters:
    `representation` - list of {0,1} values representing the chromosome

### BinaryChromosome

    public BinaryChromosome(Integer[] representation)

  Constructor.

  Parameters:
    `representation` - array of {0,1} values representing the chromosome

Method Detail

### checkValidity

    protected void checkValidity(List<Integer> chromosomeRepresentation)
                          throws InvalidRepresentationException

  Asserts that `representation` can represent a valid chromosome.

  Specified by:
    `checkValidity` in class `AbstractListChromosome<Integer>`
  Parameters:
    `chromosomeRepresentation` - representation of the chromosome
  Throws:
    `InvalidRepresentationException` - iff the `representation` can not represent a valid chromosome

### randomBinaryRepresentation

    public static List<Integer> randomBinaryRepresentation(int length)

  Returns a representation of a random binary array of length `length`.

  Parameters:
    `length` - length of the array
  Returns:
    a random binary array of length `length`

### isSame

    protected boolean isSame(Chromosome another)

  Returns `true`iff `another` has the same representation and therefore the same fitness. By default, it returns false -- override it in your implementation if you need it.

  ``
  Overrides:
    `isSame` in class `Chromosome`
  Parameters:
    `another` - chromosome to compare
  Returns:
    true if `another` is equivalent to this chromosome
