What a run found.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

point: Vec<f64>

The best point evaluated, one value per variable, in the variables’ order, as the model was given it (an integer variable’s value encoded).

value: f64

The model’s value there: +∞ if no candidate gave a finite value (serialized as none, a JSON null).

violation: f64

Its constraint violation (Evaluation::violation): zero if it keeps every constraint, and always zero for a run told plain values; +∞ if every candidate failed (serialized as none).

evaluation: usize

Which evaluation found it, counted from 1.

evaluations: usize

How many evaluations the run made.

generations: usize

How many generations it ran.

mean: Vec<f64>

The distribution’s final mean, not encoded: an integer variable’s may lie between whole numbers or outside its bounds (Variable::encode gives the value it stands for).

spread: f64

The distribution’s largest standard deviation in any one variable, in that variable’s units: the largest σ √Cᵢᵢ times the variable’s step and its margin scale Aᵢ; +∞ once the step size has overflowed (serialized as none, a JSON null). An integer variable at an inner value keeps it large enough for the margin (its Aᵢ grows), so then it doesn’t shrink to zero; at an end value only the mean moves, and it may.

stop: Stop

Why it stopped.

Trait Implementations

impl Clone for Optimum

fn clone(&self) -> Optimum

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Optimum

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Optimum

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Optimum

fn eq(&self, other: &Optimum) -> 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 Optimum

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
