Constructor Detail

BinaryChromosome

public BinaryChromosome(List<Integer> representation)
                 throws InvalidRepresentationException
Constructor.

Parameters:
representation - list of {0,1} values representing the chromosome
Throws:
InvalidRepresentationException - iff the representation can not represent a valid chromosome

BinaryChromosome

public BinaryChromosome(Integer[] representation)
                 throws InvalidRepresentationException
Constructor.

Parameters:
representation - array of {0,1} values representing the chromosome
Throws:
InvalidRepresentationException - iff the representation can not represent a valid 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)
Description copied from class: Chromosome
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
