Implementations

impl<T: Allele> Population<T>

pub fn new(chromosomes: Vec<Chromosome<T>>, recycling: bool) -> Self

pub fn new_empty(recycling: bool) -> Self

pub fn size(&self) -> usize

pub fn parents_and_offspring_size(&self) -> (usize, usize)

pub fn shuffle<R: Rng>(&mut self, rng: &mut R)

pub fn reset_age(&mut self)

pub fn increment_age(&mut self)

pub fn recycled_size(&self) -> usize

pub fn new_chromosome(&mut self, source: &Chromosome<T>) -> Chromosome<T>

Get a recycled chromosome or create new one by cloning source

pub fn drop_chromosome(&mut self, chromosome: Chromosome<T>)

Recycle the chromosome or just drop it

pub fn truncate(&mut self, keep_size: usize)

Truncate a population and add truncated chromosomes to recycling bin

pub fn truncate_external( &mut self, chromosomes: &mut Vec<Chromosome<T>>, keep_size: usize, )

Truncate a detached vector and add truncated chromosomes to recycling bin Used when chromosomes are temporarily outside the population (e.g. during selection)

pub fn extend_from_within(&mut self, amount: usize)

Extend population by amount, reusing recycled chromosomes if available

pub fn best_chromosome( &self, fitness_ordering: FitnessOrdering, ) -> Option<&Chromosome<T>>

fitness_score is Option and None is least, but invalid as best_chromosome, so filter it out when minimizing the fitness score, otherwise None would end up as best.

pub fn best_chromosome_index( &self, fitness_ordering: FitnessOrdering, ) -> Option<usize>

pub fn best_chromosome_indices( &self, amount: usize, fitness_ordering: FitnessOrdering, ) -> Vec<usize>

pub fn unique_chromosome_indices(&self) -> Vec<usize>

pub fn best_unique_chromosome_indices( &self, amount: usize, fitness_ordering: FitnessOrdering, ) -> Vec<usize>

pub fn age_mean(&self) -> f32

pub fn fitness_score_count(&self) -> usize

pub fn fitness_score_median(&self) -> Option<isize>

pub fn fitness_score_mean(&self) -> f32

pub fn fitness_score_stddev(&self) -> f32

pub fn fitness_score_cardinality(&self) -> Option<usize>

pub fn genes_cardinality(&self) -> Option<usize>

Trait Implementations

impl<T: Clone + Allele> Clone for Population<T>

fn clone(&self) -> Population<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Allele> Debug for Population<T>

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

Formats the value using the given formatter.

impl<T: Allele> From<Vec<Chromosome<T>>> for Population<T>

fn from(chromosomes: Vec<Chromosome<T>>) -> Self

Converts to this type from the input type.
