Trait optimization::problems::Problem [−] [src]

pub trait Problem: Function + Default {
    fn dimensions(&self) -> usize;
    fn domain(&self) -> Vec<(f64, f64)>;
    fn minimum(&self) -> (Vec<f64>, f64);
    fn random_start(&self) -> Vec<f64>;

    fn is_legal_position(&self, position: &[f64]) -> bool { ... }
}

Specifies a well known optimization problem.

Required Methods

fn dimensions(&self) -> usize

Returns the dimensionality of the input domain.

fn domain(&self) -> Vec<(f64, f64)>

Returns the input domain of the function in terms of upper and lower, respectively, for each input dimension.

fn minimum(&self) -> (Vec<f64>, f64)

Returns the position as well as the value of the global minimum.

fn random_start(&self) -> Vec<f64>

Generates a random and feasible position to start a minimization.

Provided Methods

fn is_legal_position(&self, position: &[f64]) -> bool

Tests whether the supplied position is legal for this function.
