Method Detail

fitness

public double fitness()

Description copied from interface: Fitness

Compute the fitness. This is usually very time-consuming, so the value should be cached.

Returns:

fitness

checkValidity

protected void checkValidity(List<Character> repr)
                      throws MathIllegalArgumentException

Description copied from class: AbstractListChromosome

Asserts that representation can represent a valid chromosome.

Specified by:

checkValidity in class AbstractListChromosome<Character>

Parameters:

repr - representation of the chromosome

Throws:

MathIllegalArgumentException - iff the representation can not represent a valid chromosome

getStringRepresentation

public List<Character> getStringRepresentation()

newFixedLengthChromosome

public HelloWorldExample.StringChromosome newFixedLengthChromosome(List<Character> repr)

Description copied from class: AbstractListChromosome

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.

Specified by:

newFixedLengthChromosome in class AbstractListChromosome<Character>

Parameters:

repr - the inner array representation of the new chromosome.

Returns:

new instance extended from FixedLengthChromosome with the given arrayRepresentation

toString

public String toString()

Description copied from class: AbstractListChromosome

Overrides:

toString in class AbstractListChromosome<Character>
