Struct EvolutionModel 

pub struct EvolutionModel<G, F>
where
    G: EvolutionaryGenome,
    F: Fitness<Genome = G, Value = f64>,
{
    pub fitness: F,
    /* private fields */
}

A probabilistic model of an evolutionary step

This wraps an evolutionary genome in Fugue’s Model monad, enabling integration with SMC and MCMC inference.

Fields

fitness: F

The fitness function used for conditioning

Implementations

impl<G, F> EvolutionModel<G, F>

where G: EvolutionaryGenome, F: Fitness<Genome = G, Value = f64>,

pub fn new(fitness: F, bounds: MultiBounds) -> Self

Create a new evolution model

pub fn with_temperature(self, temperature: f64) -> Self

Set the temperature for fitness weighting

Lower temperature = stronger selection pressure

pub fn sample_prior<R: Rng>(&self, rng: &mut R) -> G

Sample a genome from the prior (uniform within bounds)

pub fn log_weight(&self, genome: &G) -> f64

Compute the log-weight for a genome based on fitness

w(x) = exp(f(x) / T) where T is temperature

pub fn to_weighted_trace(&self, genome: &G) -> Trace

Create a Fugue trace representing this genome with fitness weight

Trait Implementations

impl<G, F> Clone for EvolutionModel<G, F>

where G: EvolutionaryGenome + Clone, F: Fitness<Genome = G, Value = f64> + Clone,

fn clone(&self) -> EvolutionModel<G, F>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
