Struct SearchEngine 

pub struct SearchEngine { /* private fields */ }

The search engine: combines Sobol initial design with k-NN + EI Bayesian optimization.

Implementations

impl SearchEngine

pub fn new(space: ConfigurationSpace, budget: usize) -> Self

pub fn trials(&self) -> usize

Number of trials so far.

pub fn best_value(&self) -> f64

Best objective value seen.

pub fn ask(&mut self) -> Option<Configuration>

Ask for the next configuration to try. Returns None if the budget is exhausted.

pub fn tell(&mut self, cfg: &Configuration, result: &ExperimentResult)

Tell the engine the result of an experiment.

pub fn surrogate_add( &mut self, normalized: Vec<f64>, objective: f64, config_hash: u64, )

Directly add an observation to the surrogate (for resuming from a log). The normalized vector and config hash must be pre-computed.

pub fn best_config(&self) -> Option<u64>

Get the best configuration found so far (by scalar objective).
