Struct cosyne::Population

pub struct Population { /* fields omitted */ }

stores all sub-populations and their fitness values

Implementations

impl Population

pub fn set_mutation_prob(&mut self, mp: f64)

Set the mutation probability of the population panics in debug mode if mp < 0.0 || mp > 1.0

pub fn set_mutation_strength(&mut self, ms: f64)

Set the mutation strength of the population panics in debug mode if mp < 0.0 || mp > 1.0

pub fn set_perturb_prob(&mut self, pp: f64)

Set the perturb probability of the population panics in debug mode if pp < 0.0 || pp > 1.0

pub fn get_network(&self, j: usize) -> ANN

Return a neural network at index j

pub fn get_network_fitness(&self, j: usize) -> f64

Return the fitness of a given network

pub fn new(config: Config, nn: &ANN) -> Population

Create a new population with a given config and network

pub fn evolve(&mut self)

Perform a single generational evolutionary step in a given environment assumes all network have been evaluated and their fitness updated

pub fn update_fitnesses(&mut self, new_fits: &Vec<f64>)

Update existing chromosome fitnesses with the new network fits
