Struct Individual 

pub struct Individual<G, F = f64>
where
    G: EvolutionaryGenome,
    F: FitnessValue,
{
    pub genome: G,
    pub fitness: Option<F>,

}

An individual in the population

Wraps a genome with its computed fitness value and additional metadata.

Fields

genome: G

The genome of this individual

fitness: Option<F>

The fitness value (None if not yet evaluated)

birth_generation: usize

Generation when this individual was created

offspring_count: usize

Number of offspring produced by this individual

Implementations

impl<G, F> Individual<G, F>

where G: EvolutionaryGenome, F: FitnessValue,

Create a new individual with a known fitness

pub fn with_generation(genome: G, generation: usize) -> Self

Create a new individual with birth generation

pub fn is_evaluated(&self) -> bool

Check if this individual has been evaluated

pub fn fitness_value(&self) -> &F

Get the fitness value, panicking if not evaluated

pub fn fitness_f64(&self) -> f64

Get the fitness as f64

pub fn set_fitness(&mut self, fitness: F)

Set the fitness value

pub fn into_genome(self) -> G

Take the genome out of this individual

pub fn genome(&self) -> &G

Get a reference to the genome

pub fn genome_mut(&mut self) -> &mut G

Get a mutable reference to the genome

pub fn is_better_than(&self, other: &Self) -> bool

Check if this individual is better than another

pub fn age(&self, current_generation: usize) -> usize

Age of this individual (generations since birth)

Trait Implementations

impl<G, F> Clone for Individual<G, F>

where G: EvolutionaryGenome + Clone, F: FitnessValue + Clone,

fn clone(&self) -> Individual<G, F>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<G, F> Debug for Individual<G, F>

where G: EvolutionaryGenome + Debug, F: FitnessValue + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de, G, F> Deserialize<'de> for Individual<G, F>

where G: EvolutionaryGenome, F: FitnessValue,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<G, F> FromIterator<Individual<G, F>> for Population<G, F>

where G: EvolutionaryGenome, F: FitnessValue,

fn from_iter<I: IntoIterator<Item = Individual<G, F>>>(iter: I) -> Self

Creates a value from an iterator.

impl<G, F> PartialEq for Individual<G, F>

where G: EvolutionaryGenome + PartialEq, F: FitnessValue + PartialEq,

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<G, F> PartialOrd for Individual<G, F>

where G: EvolutionaryGenome + PartialEq, F: FitnessValue + PartialEq,

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<G, F> Serialize for Individual<G, F>

where G: EvolutionaryGenome, F: FitnessValue,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
