Enum Problem 

pub enum Problem {
    Rastrigin,
    ShiftedQuadratic,
}

A built-in minimization problem.

Variants

Rastrigin

The 2-D Rastrigin function on [-5.12, 5.12]²; global minimum 0 at the origin, surrounded by a regular grid of local minima.

ShiftedQuadratic

(x - 1.25)² on [-5, 5]; minimum 0 at x = 1.25. A one-dimensional regression fixture, not shown in the browser.

Implementations

impl Problem

pub const fn name(self) -> &'static str

The study name used for this problem.

pub const fn bounds(self) -> &'static [Bound]

The declared parameters, in suggestion order.

pub const fn optimum(self) -> f64

The known global minimum value.

pub fn evaluate(self, params: &[f64]) -> f64

Evaluates the objective at params (one value per Self::bounds entry, in order).
