Constructor Detail

BinaryChromosome

public BinaryChromosome(List<Integer> representation)

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)

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)

Asserts that representation can represent a valid chromosome.

Specified by:

checkValidity in class AbstractListChromosome<Integer>

Parameters:

chromosomeRepresentation - representation of the 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
