Struct ExtensionMassExtinction 

pub struct ExtensionMassExtinction {
    pub cardinality_threshold: usize,
    pub survival_rate: f32,
    pub elitism_rate: f32,
}

Simulates a cambrian explosion. The controlling metric is population cardinality in the population after selection. When this cardinality drops to the threshold, the population is randomly reduced regardless of fitness using the survival_rate (fraction of population). The elitism_rate ensures the passing of the best chromosomes before random reduction starts (doesn’t care about best chromosome uniqueness).

Population will recover in the following generations

Fields

cardinality_threshold: usize

survival_rate: f32

elitism_rate: f32
