Trait cmaes::fitness::FitnessFunction

pub trait FitnessFunction {
    fn get_fitness(&self, parameters: &[f64]) -> f64;
}

The cmaes_loop function requires a type that implements this trait. Use the self argument to get additional data to factor into the fitness calculation from other struct fields. Implementing it for a dummy type also works.

Examples

use cmaes::FitnessFunction;

#[derive(Clone)]
struct FitnessDummy;

impl FitnessFunction for FitnessDummy {
    fn get_fitness(&self, parameters: &[f64]) -> f64 {
        // Calculate fitness of the parameters
        parameters[0] + parameters[1]
    }
}

Required Methods

fn get_fitness(&self, parameters: &[f64]) -> f64
