Constructor Detail

DistanceMutator

public DistanceMutator(double probability)

Standard probability constructor. Utilized by the ConfigPanel.

Parameters:

probability - the mutation probability

Method Detail

mutate

protected DiscreteGene mutate(DiscreteGene gene,
                              Random random)

Mutate the genes distance. Adds a random value from the interval [-1.0, 1.0) to the distance.

Overrides:

mutate in class io.jenetics.Mutator<DiscreteGene,Double>

Parameters:

gene - gene to mutate

random - random object for random doubles

Returns:

gene with mutated distance

setConfiguration

public void setConfiguration(Configuration configuration)

Configuration for the alterers to work with.
