Struct Mutation 

pub struct Mutation {
    pub point_rate: f64,
    pub crossover: CrossoverMethod,
    pub crossover_rate: f64,
}

Mutation configuration.

Fields

point_rate: f64

Probability of point mutation per position.

crossover: CrossoverMethod

Crossover method.

crossover_rate: f64

Crossover probability (if not crossed over, child = clone of parent).

Implementations

impl Mutation

pub fn default_rates() -> Self

Default mutation: 1% point mutation rate, single-point crossover at 70%.

pub fn point_mutate(&self, agent: &mut TernaryAgent, rng: &mut SimpleRng)

Apply point mutation to a single agent (modifies in place). Each position has point_rate chance of being randomly changed.

pub fn crossover( &self, parent_a: &TernaryAgent, parent_b: &TernaryAgent, rng: &mut SimpleRng, ) -> (TernaryAgent, TernaryAgent)

Crossover two parents to produce two children.

pub fn mutate(&self, agent: &mut TernaryAgent, rng: &mut SimpleRng)

Apply mutation (point mutation) to an agent.

Trait Implementations

impl Clone for Mutation

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Mutation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
