Member Data Documentation

MutateBothParentsAndChildren

bool grail::evolution::Mutation::MutateBothParentsAndChildren = false

If true: both the previous population and children can be mutated; if false: only the individuals after crossover can be mutated.

MutateChromosomeRate

double grail::evolution::Mutation::MutateChromosomeRate = 0.0

Probability that a chromosome of an individual will be considered for mutation (randomResolutionTypeForChromosome == ITERATE_AND_TEST_P); or the portion of chromosomes within an individual chosen for mutation (randomResolutionTypeForChromosome == SELECT_P_OF_N).

MutateIndividualRate

double grail::evolution::Mutation::MutateIndividualRate = 0.0

Probability that an individual will be considered for mutation (randomResolutionTypeForIndividual == ITERATE_AND_TEST_P); or the portion of individuals chosen for mutation (randomResolutionTypeForIndividual == SELECT_P_OF_N).

MutationPhaseRate

double grail::evolution::Mutation::MutationPhaseRate = 0.0

Probability of a mutation phase to happen (globally). If a mutation is included in the algorithm, this value should most likely be equal to 1.0.
