Constructor Detail

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.

Since:

3.3

Method Detail

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
