optimization

Collection of optimization algorithms and strategies.

Usage

extern crate optimization;

use optimmization::{Minimizer, GradientDescent, NumericalDifferentiation, Func};

// numeric version of the Rosenbrock function
let function = NumericalDifferentiation::new(Func(|x: &[f64]| {
    (1.0 - x[0]).powi(2) + 100.0*(x[1] - x[0].powi(2)).powi(2)
}));

// we use a simple gradient descent scheme
let minimizer = GradientDescent::new();

// perform the actual minimization, depending on the task this may
// take some time, it may be useful to install a log sink to see
// what's going on
let solution = minimizer.minimize(&function, vec![-3.0, -4.0]);

println!("Found solution for Rosenbrock function at f({:?}) = {:?}",
    solution.position, solution.value);

Installation
