Trait Implementations§

Source§

impl<F, G> ConstrainedProblem for ConstrainedFunc<F, G>
where F: Fn(&[f64]) -> f64, G: Fn(&[f64]) -> Vec<f64>,

Source§

fn dim(&self) -> usize

Number of decision variables.
Source§

fn bounds(&self) -> &[Bound] ⓘ

Per-variable inclusive bounds, length ConstrainedProblem::dim.
Source§

fn objective(&self, x: &[f64]) -> f64

Objective value to minimize (non-finite ⇒ infeasible, as usual).
Source§

fn violations(&self, x: &[f64]) -> Vec<f64>

Constraint violations: 0.0 per satisfied constraint, positive magnitudes otherwise. Negative entries are clamped to 0.0.
Source§

fn total_violation(&self, x: &[f64]) -> f64

Total violation Σ max(vᵢ, 0) — the quantity Deb’s rules compare.
