Enum Scalarizer 

#[non_exhaustive]
pub enum Scalarizer {
    WeightedSum,
    AugmentedTchebycheff {
        rho: f64,
    },
}

How a CompositeObjective combines its weighted terms.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

WeightedSum

Σ wᵢ·vᵢ — the plain weighted sum.

AugmentedTchebycheff

Augmented weighted min/max (Tchebycheff-style, Knowles 2006): emphasizes the worst-performing term so non-convex trade-offs aren’t missed. For Maximize: minᵢ(wᵢ·vᵢ) + ρ·Σ wᵢ·vᵢ; for Minimize the min becomes a max.

Fields

rho: f64

Weight of the augmenting sum term. 0.0 is pure worst-case; small values (~0.05–0.1) keep the sum as a tie-breaker.

Trait Implementations

impl Clone for Scalarizer

fn clone(&self) -> Scalarizer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scalarizer

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

Formats the value using the given formatter.

impl Default for Scalarizer

fn default() -> Scalarizer

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Scalarizer

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Scalarizer

fn eq(&self, other: &Scalarizer) -> 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 Serialize for Scalarizer

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Scalarizer

impl StructuralPartialEq for Scalarizer
