Struct BoltzmannSelection 

pub struct BoltzmannSelection {
    pub temperature: f64,
}

Boltzmann selection (temperature-based)

Uses softmax of fitness values scaled by temperature.

Fields

temperature: f64

Temperature parameter (higher = more uniform, lower = more greedy)

Implementations

impl BoltzmannSelection

pub fn new(temperature: f64) -> Self

Create a new Boltzmann selection
