Struct genetic_algorithm::mutate::MutateMultiGene

pub struct MutateMultiGene {
    pub number_of_mutations: usize,
    pub mutation_probability: f32,
}

Selects Chromosomes in the Population with the provided mutation_probability. Then mutates the selected chromosomes the provided number of times, where the Genotype determines whether this is random, relative or scaled.

Duplicate mutations of the same gene are allowed, as disallowing duplicates is relatively expensive and mutations should be quite small, so there is little chance for conflict.

Useful when a single mutation would generally not lead to improvement, because the problem space behaves more like a UniqueGenotype where genes must be swapped (but the UniqueGenotype doesn’t map to the problem space well). Set number_of_mutations to two in that situation.

Fields

number_of_mutations: usize

mutation_probability: f32
