Struct genetic_algorithm::chromosome::Chromosome

pub struct Chromosome<G: Genotype> {
    pub genes: G::Genes,
    pub fitness_score: Option<FitnessValue>,
    pub age: usize,
    pub reference_id: usize,
}

The Chromosome is used as an individual in the Population. It holds the genes and knows how to sort between itself with regard to it’s fitness score. Chromosomes crossover, mutate and compete with each other in the Evolve strategy

Fields

genes: G::Genes

fitness_score: Option<FitnessValue>

age: usize

reference_id: usize

User controlled alternative to genes_key(), set manually in custom Fitness implementation. Defaults to 0

Implementations

impl<G: Genotype> Chromosome<G>

where G::Genes: Hash,

Cannot Hash floats

pub fn genes_key(&self) -> GenesKey

impl<G: Genotype> Chromosome<G>

pub fn new(genes: G::Genes) -> Self

pub fn taint_fitness_score(&mut self)

Reset fitness_score for recalculation

Trait Implementations

impl<G: Clone + Genotype> Clone for Chromosome<G>

where G::Genes: Clone,

fn clone(&self) -> Chromosome<G>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<G: Debug + Genotype> Debug for Chromosome<G>

where G::Genes: Debug,

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

Formats the value using the given formatter.

impl<G: Genotype> Display for Chromosome<G>

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

Formats the value using the given formatter.

impl<G: Genotype> Ord for Chromosome<G>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<G: Genotype> PartialEq for Chromosome<G>

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: Genotype> PartialOrd for Chromosome<G>

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.
