Constructor Detail

PositionMutator

public PositionMutator(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 position. Chooses a new position randomly.

Overrides:

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

Parameters:

gene - gene to mutate

random - random object for random doubles

Returns:

gene with mutated position
