Struct ConvergenceDetector 

pub struct ConvergenceDetector {
    pub plateau_threshold: usize,
    pub fitness_tolerance: f64,
    pub species_stability_threshold: usize,
    pub fitness_history: Vec<f64>,
}

Detects convergence based on fitness plateau and species stability.

Fields

plateau_threshold: usize

How many generations of flat fitness before declaring convergence.

fitness_tolerance: f64

Minimum relative change in avg fitness to count as “improving”.

species_stability_threshold: usize

How many generations of stable species before declaring convergence.

fitness_history: Vec<f64>

History of average fitness per generation.

Implementations

impl ConvergenceDetector

pub fn default_detector() -> Self

Default detector: 15 generations, 0.001 tolerance.

pub fn record(&mut self, avg_fitness: f64)

Record a generation’s average fitness.

pub fn check(&self, species: &SpeciesTracker) -> ConvergenceStatus

Check convergence based on fitness history and species tracker.
