Struct Rastrigin 

pub struct Rastrigin { /* private fields */ }

Rastrigin: f(x) = 10n + Σ [xᵢ² − 10 cos(2π xᵢ)]. Highly multimodal with a regular lattice of local minima; global minimum 0 at the origin.

Implementations

impl Rastrigin

pub fn new(dim: usize) -> Self

dim-dimensional Rastrigin on [-5.12, 5.12]^dim.

Trait Implementations

impl Problem for Rastrigin

fn dim(&self) -> usize

Number of decision variables.

fn bounds(&self) -> &[Bound]

Per-variable inclusive bounds, length Problem::dim.

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

Objective value to minimize. A non-finite return marks the point as infeasible; optimizers will reject it rather than crash.
