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);
