//! Standard optimization test problems.
//!
//! Each problem is exposed three ways:
//! - Raw functions on `&[f64]` slices (e.g.
//!   [`rosenbrock()`](crate::problems::rosenbrock::rosenbrock)) for callers that
//!   want to plug the math into their own wrappers, benchmarks, or visualizations.
//! - A pre-wrapped struct (e.g. [`Rosenbrock`](crate::problems::Rosenbrock))
//!   implementing
//!   [`CostFunction`](crate::CostFunction) and [`Gradient`](crate::Gradient)
//!   for each enabled backend, so it can be handed straight to an
//!   [`Executor`](crate::Executor).
//! - A static [`ProblemSpec`](crate::problems::ProblemSpec) with metadata
//!   (dimensionality, mathematical
//!   properties, references) for use in catalog UIs and filtering. Iterate
//!   [`ALL_SPECS`](crate::problems::ALL_SPECS) to enumerate the corpus.
//!
//! Most functions in this corpus are catalogued in Jamil & Yang (2013),
//! *A Literature Survey of Benchmark Functions For Global Optimisation
//! Problems*, arXiv:1308.4008. Per-problem references on each
//! [`ProblemSpec`](crate::problems::ProblemSpec) cite the original source where
//! applicable.
//!
//! Gated behind the `problems` feature (default-on). Disable with
//! `default-features = false` to drop the corpus from the build.
