mod objective

module objective

The Objective trait: typed S -> R map with bounds and optional known minimum. The Objective trait: a typed function Obj : S -> R from the IISE manuscript.

Traits

trait Objective<T: Float>

A real-valued function on R^dim with a known feasible domain.

The IISE manuscript’s Obj signature: a typed map from a state space S = R^dim (with Bounds) to R. Implementors may override eval_batch and global_min for performance or known-optima instrumentation.

Functions

fn bounds(&self) -> &Bounds<T>

The feasible domain (typically a box).

fn dim(&self) -> usize

Number of input dimensions; matches bounds().dims.

fn eval(&self, x: ArrayView1<T>) -> T

Evaluates the objective at a single point.

fn eval_batch(&self, x: ArrayView2<T>) -> Array1<T>

Evaluates at a batch of points; default implementation iterates eval.

fn global_min(&self) -> Option<&FPair<T>>

Optional known global minimum, used for benchmarking and convergence checks. Default returns None.
