Enum ConstrainedAcquisitionStrategy 

pub enum ConstrainedAcquisitionStrategy {
    ExpectedFeasibleImprovement,
    ProbabilityOfFeasibility,
    ConstrainedExpectedImprovement,
    AugmentedLagrangian {
        penalty: f64,
    },
}

Strategy for handling constraints in the acquisition function.

Variants

ExpectedFeasibleImprovement

Expected Improvement weighted by the product of probabilities of feasibility for all constraints (EFI = EI * Prod_i PoF_i).

ProbabilityOfFeasibility

Pure probability of feasibility: Prod_i PoF_i. Useful for cold-start when no feasible point is known.

ConstrainedExpectedImprovement

Constrained EI: EI penalised multiplicatively by PoF.

AugmentedLagrangian

Augmented Lagrangian BO: treats constraint violation as an additive penalty to the objective surrogate.

Fields

penalty: f64

Penalty weight for constraint violations.

Trait Implementations

impl Clone for ConstrainedAcquisitionStrategy

fn clone(&self) -> ConstrainedAcquisitionStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstrainedAcquisitionStrategy

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

Formats the value using the given formatter.

impl Default for ConstrainedAcquisitionStrategy

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ConstrainedAcquisitionStrategy

fn eq(&self, other: &ConstrainedAcquisitionStrategy) -> 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.
