Method Details

mutate

public Genotype mutate(long generation,
 Genotype original)

Description copied from interface: Mutator

Applies mutation to the given genotype and returns a new mutated genotype.

The original genotype should not be modified; instead, a new genotype with the mutations applied should be returned. The specific mutation behavior depends on the implementation and the mutation policy being used.

Mutation may affect:

• Individual alleles within chromosomes (bit flips, value changes)
• Chromosome structure (for variable-length representations)
• Multiple chromosomes simultaneously

Specified by:

mutate in interface Mutator

Parameters:

generation - the current generation

original - the genotype to mutate, must not be null

Returns:

a new genotype with mutations applied, never null
