Struct moonlander_gp::Population

pub struct Population<P: Clone + Sync, F: Fitness + Sized + Send> {
    pub population: Vec<P>,
    pub generation: u32,
    pub scores: Vec<F>,
}

Collection of programs

The root of each program is of type P, and fitness structures will be represented by type F.

Fields

population: Vec<P>

Collection of algorithms

generation: u32

Generation index of this population

scores: Vec<F>

Collection of fitness scores

Methods

impl<P: Clone + Sync, F: Fitness + Sized + Send> Population<P, F>

fn new(n: usize, generation: u32) -> Population<P, F>

Create a new population with an estimated size.

This does not create programs yet but simply allocates memory.

fn add(&mut self, program: P)

Add a single program to the population.

fn n(&self) -> usize

fn score<S>(&mut self, scoring_fn: S, _: &mut Rng) where
    S: Fn(&P, &mut Rng) -> F + Sync, 

Apply a scoring function to the entire population.

fn avg_score(&self) -> Number

fn best_score(&self) -> Number

fn champion<'a>(&'a self) -> CreatureScore<'a, P, F> where
    P: Encodable,
    F: Encodable, 

Return the best program from the population.

fn best_n<'a>(&self, n: usize) -> Vec<P>

Return the best N programs from the population.
