Struct ContinuousUnivariateModel 

pub struct ContinuousUnivariateModel {
    pub means: Vec<f64>,
    pub variances: Vec<f64>,
}

Univariate model for continuous variables

Fields

means: Vec<f64>

Mean for each dimension

variances: Vec<f64>

Variance for each dimension

Implementations

impl ContinuousUnivariateModel

pub const MAX_REJECTION_RETRIES: usize = 100

Maximum number of rejection retries per coordinate before clamping (EV-39).

pub fn from_bounds(bounds: &MultiBounds) -> Self

Create from bounds (initial uniform-ish distribution)

pub fn update(&mut self, selected: &[&RealVector], config: &UMDAConfig)

Update model from selected individuals

pub fn sample<R: Rng>(&self, bounds: &MultiBounds, rng: &mut R) -> RealVector

Sample a new individual from the model.

EV-39: each coordinate is drawn by rejection from the truncated Gaussian — out-of-bounds draws are retried up to Self::MAX_REJECTION_RETRIES times before falling back to a clamp. For interior-optimum problems this makes the boundary “atoms” (probability mass piled on a bound by naive clamping) vanish, so the accepted samples that feed the next variance estimate are genuine spread rather than collapsed boundary points.
