A trait which models a population with individuals (solutions).
Required methods
fn add_all(&mut self, individuals: Vec<Individual>) -> bool
Adds all individuals into the population, then sorts and shrinks population if necessary. Returns true if any of newly added individuals is considered as best known.
fn add(&mut self, individual: Individual) -> bool
Adds an individual into the population. Returns true if newly added individual is considered as best known.
fn nth(&self, idx: usize) -> Option<&Individual>
Gets nth individual from population.
fn cmp(&self, a: &Individual, b: &Individual) -> Ordering
Compares two solutions the same way as population does.
fn ranked<'a>(&'a self) -> Box<dyn Iterator<Item = (&Individual, usize)> + 'a>
Returns individuals within their rank sorted according their quality.
fn size(&self) -> usize
Returns population size.
