[−][src]Trait genevo::genetic::FitnessFunction

pub trait FitnessFunction<G, F>: Clone where
    G: Genotype,
    F: Fitness, {
    fn fitness_of(&self, a: &G) -> F;
    fn average(&self, a: &[F]) -> F;
    fn highest_possible_fitness(&self) -> F;
    fn lowest_possible_fitness(&self) -> F;
}

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`

Calculates the Fitness value of the given Genotype.

`fn average(&self, a: &[F]) -> F`

Calculates the average Fitness value of the given Fitness values.

`fn highest_possible_fitness(&self) -> F`

Returns the very best of all theoretically possible Fitness values.

`fn lowest_possible_fitness(&self) -> F`

Returns the worst of all theoretically possible Fitness values. This is usually a value equivalent to zero.
