Struct UMDAConfig 

pub struct UMDAConfig {
    pub population_size: usize,
    pub selection_ratio: f64,
    pub min_variance: f64,
    pub prob_bounds: (f64, f64),
    pub learning_rate: f64,
}

Configuration for UMDA.

The builder (UMDABuilder) validates these fields in build() and returns an error for out-of-range values (EV-79) — it no longer silently clamps them. All fields are public, so constructing UMDAConfig directly is a deliberate escape hatch that bypasses that validation; if you build the struct by hand, keep the documented ranges yourself.

Fields

population_size: usize

Population size (must be >= 1).

selection_ratio: f64

Selection ratio: the top proportion selected for model learning. Must lie in the open-closed interval (0.0, 1.0].

min_variance: f64

Minimum variance to prevent collapse (continuous). Must be >= 0.0.

prob_bounds: (f64, f64)

Probability bounds (min, max) for binary UMDA (to prevent determinism). Must satisfy 0.0 < min <= max < 1.0.

learning_rate: f64

Learning rate for the model update (1.0 = replace, <1.0 = blend with the previous model). Must lie in (0.0, 1.0]; 0.0 is rejected because it makes the update a no-op (the model never learns).

Implementations

impl UMDAConfig

pub fn validate(&self) -> Result<(), EvolutionError>

Validate the configuration ranges (EV-79). Called by build(); returns a EvolutionError::Configuration describing the first out-of-range field.

Trait Implementations

impl Clone for UMDAConfig

fn clone(&self) -> UMDAConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UMDAConfig

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

Formats the value using the given formatter.

impl Default for UMDAConfig

fn default() -> Self

Returns the “default value” for a type.
