Expand description

A sampler the demo can run. Each choice is a separate, separately seeded run; the demo never ranks them.

Variants§

§

Random

Independent uniform draws.

§

Grid

An exhaustive square lattice in a fixed order, as large as the budget holds.

§

Qmc

The Sobol low-discrepancy sequence.

§

Tpe

Tree-structured Parzen estimator; its first ten trials are uniform startup draws before the model takes over.

§

Cmaes

Covariance matrix adaptation evolution strategy over the declared box.

§

GpEi

Gaussian-process expected improvement with closed-form hyperparameters.

§

Nsga2

NSGA-II, an elitist genetic algorithm with one objective.

§

Dehb

Differential-evolution Hyperband over the 1, 3, 9 step ladder.

§

Carbs

Cost-aware Bayesian optimization over a declared second objective.

Implementations§

§

impl SamplerChoice

pub const ALL: [Self; 9]

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

The stable identifier used in URLs and form values.

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