Constructor Detail

AbstractListChromosome

public AbstractListChromosome(List<T> representationIn)

Constructor.

Parameters:

representationIn - inner representation of the chromosome

Throws:

InvalidRepresentationException - iff the representation can not represent a valid chromosome

AbstractListChromosome

public AbstractListChromosome(T[] representationIn)

Constructor.

Parameters:

representationIn - inner representation of the chromosome

Throws:

InvalidRepresentationException - iff the representation can not represent a valid chromosome

Method Detail

checkValidity

protected abstract void checkValidity(List<T> chromosomeRepresentation)

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
