Variants

None

No boundary handling (unconstrained)

Projection

Project infeasible solutions onto the boundary

Reflection

Reflect infeasible solutions at the boundary

Penalty

Penalize infeasible solutions with a quadratic penalty

Penalty weight factor

Resampling

Resample infeasible solutions until feasible

Fields

max_attempts: usize

Maximum number of resampling attempts

Trait Implementations

impl Clone for BoundaryHandling

fn clone(&self) -> BoundaryHandling

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BoundaryHandling

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

Formats the value using the given formatter.

impl Default for BoundaryHandling

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for BoundaryHandling

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

impl Copy for BoundaryHandling

impl StructuralPartialEq for BoundaryHandling
