Struct CmsaEsConfig 

pub struct CmsaEsConfig {
    pub pop_size: usize,
    pub genome_dim: usize,
    pub bounds: Bounds,
    pub initial_sigma: f32,
    pub mu: usize,
    pub tau: f32,
    pub tau_c: f32,
}

Static configuration for a CMSA-ES run.

Fields

pop_size: usize

Offspring population size λ.

genome_dim: usize

Genome dimensionality D.

bounds: Bounds

Search-space bounds; used only to sample the initial mean m⁰.

initial_sigma: f32

Initial global step size σ̄.

mu: usize

Number of selected parents μ = ⌊λ/2⌋.

tau: f32

Log-normal σ-self-adaptation learning rate τ = 1/√(2D).

tau_c: f32

Covariance time constant τ_c = 1 + D(D+1)/(2μ).

Implementations

impl CmsaEsConfig

pub fn default_for(genome_dim: usize) -> Self

Default configuration for dimensionality D, with the Hansen-style population λ = 4 + ⌊3 ln D⌋ and μ = ⌊λ/2⌋.

Sets bounds = (-5.12, 5.12) and initial_sigma = 1.0.

pub fn with_pop_size(pop_size: usize, genome_dim: usize) -> Self

Configuration with an explicit population size λ.

The pop_size ≥ 2 invariant is enforced by Validate::validate at the harness chokepoint, not by this infallible producer.

Trait Implementations

impl Clone for CmsaEsConfig

fn clone(&self) -> CmsaEsConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CmsaEsConfig

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

Formats the value using the given formatter.

impl Validate for CmsaEsConfig

fn validate(&self) -> Result<(), ConfigError>

Returns Ok(()) when every invariant holds, or the first ConfigError otherwise.

fn validate_all(&self) -> Result<(), Vec<ConfigError>>

Returns every violated invariant rather than just the first.
