Struct differential_evolution::Population

pub struct Population<F, R> where F: Fn(&[f32]) -> f32, R: Rng {
    // some fields omitted
}

Holds the population for the differential evolution based on the given settings.

Methods

impl<F, R> Population<F, R> where F: Fn(&[f32]) -> f32, R: Rng

fn new(s: Settings<F, R>) -> Population<F, R>

Creates a new population based on the given settings.

fn best(&self) -> Option<(f32, &[f32])>

Gets a tuple of the best cost and best position found so far.

fn num_cost_evaluations(&self) -> usize

Gets the total number of times the cost function has been evaluated.

fn eval(&mut self) -> Option<f32>

Performs a single cost evaluation, and updates best positions and evolves the population if the whole population has been evaluated. Returns the cost value of the current best solution found.

fn iter(&mut self) -> PopIter<F, R>

Gets an iterator for this population. Each call to next() performs one cost evaluation.
