Method Detail

mutate

protected MutatorResult<Chromosome<G>> mutate(Chromosome<G> chromosome,
                                              double p,
                                              Random random)

Mutates the given chromosome.

Overrides:

mutate in class Mutator<G extends TreeGene<A,G>,C extends Comparable<? super C>>

Parameters:

chromosome - the chromosome to mutate

p - the mutation probability for the underlying genetic objects

random - the random engine used for the genotype mutation

Returns:

the mutation result

mutate

protected abstract void mutate(TreeNode<A> tree)

This method does the actual mutating, in place.

Parameters:

tree - the mutable tree to mutate
