Constructor Detail

MeanAlterer

public MeanAlterer(double probability)

Constructs an alterer with a given recombination probability.

Parameters:

probability - the crossover probability.

Throws:

IllegalArgumentException - if the probability is not in the valid range of [0, 1].

MeanAlterer

public MeanAlterer()

Create a new alterer with alter probability of 0.05.

Method Detail

recombine

protected int recombine(MSeq<Phenotype<G,C>> population,
                        int[] individuals,
                        long generation)

Description copied from class: Recombinator

Recombination template method. This method is called 0 to n times. It is guaranteed that this method is only called by one thread.

Specified by:

recombine in class Recombinator<G extends Gene<?,G> & Mean<G>,C extends Comparable<? super C>>

Parameters:

population - the population to recombine

individuals - the array with the indexes of the individuals which are involved in the recombination step. The length of the array is Recombinator.getOrder(). The first individual is the primary individual.

generation - the current generation.

Returns:

the number of genes that has been altered.

toString

public String toString()

Overrides:

toString in class Object
