Trait genevo::genetic::FitnessFunction
source · [−]pub trait FitnessFunction<G, F>: Clone where
G: Genotype,
F: Fitness, {
fn fitness_of(&self, a: &G) -> F;
fn average(&self, a: &[F]) -> F;

}Expand description
Defines the evaluation function to calculate the Fitness value of a
Genotype based on its properties.
Required methods
fn fitness_of(&self, a: &G) -> F
fn fitness_of(&self, a: &G) -> F
Calculates the Fitness value of the given Genotype.
Calculates the average Fitness value of the given Fitness values.
fn highest_possible_fitness(&self) -> F
fn highest_possible_fitness(&self) -> F
Returns the very best of all theoretically possible Fitness values.
fn lowest_possible_fitness(&self) -> F
fn lowest_possible_fitness(&self) -> F
Returns the worst of all theoretically possible Fitness values.
This is usually a value equivalent to zero.
