Enum AcquisitionFn 

pub enum AcquisitionFn {
    ExpectedImprovement,
    UpperConfidenceBound,
    ProbabilityOfImprovement,
}

Acquisition function used to select the next candidate point.

Variants

ExpectedImprovement

Expected Improvement.

Balances exploitation (improving over the current best) and exploration (exploring uncertain regions).

UpperConfidenceBound

Upper Confidence Bound.

Combines mean and standard deviation: μ + κ σ.

ProbabilityOfImprovement

Probability of Improvement.

Probability that the next point exceeds the current best.

Trait Implementations

impl Clone for AcquisitionFn

fn clone(&self) -> AcquisitionFn

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AcquisitionFn

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for AcquisitionFn

fn eq(&self, other: &AcquisitionFn) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
