abc-algorithm

A Rust implementation of the Artificial Bee Colony (ABC) Algorithm by Karaboga [1].

Usage

#![feature(iter_arith)]

extern crate abc_algorithm;

use std::f64::consts::PI;

fn main() {
    let solution = abc_algorithm::Config::new()
        .stop(abc_algorithm::StopCriterion::TargetValue(0.0, 1.0e-10))
        .optimize(2, -5.0, 5.0, &ackley);

    println!("Best solution: {:?}", solution);
}

fn ackley(xs: &[f64]) -> f64 {
    let a = 20.0;
    let b = 0.2;
    let c = 2.0 * PI;

    -a * (-b * (xs.iter().map(|&x| x.powi(2)).sum::<f64>() / xs.len() as f64).sqrt()).exp() -
        (xs.iter().map(|&x| (c*x).cos()).sum::<f64>() / xs.len() as f64).exp() + a + 1.0f64.exp()
}
