Struct genevo::reinsertion::elitist::ElitistReinserter
source · [−]pub struct ElitistReinserter<G, F, E> where
G: Genotype,
F: Fitness,
E: FitnessFunction<G, F>, { /* private fields */ }Expand description
The ElitistReinserter combines the best individuals from the offspring and
the old population. When there are more individuals in the offspring than
necessary, either because the offspring is larger than the population size
or a replace ratio smaller then 1.0 is specified, only those individuals
with the best fitness are taken over into the new population.
The reinserter can be configured by the replace_ratio field. The
replace ratio is the fraction of the population size that is replaced by
individuals from the offspring. The remaining spots are filled with
individuals from the old population.
A replace ratio of 1.0 means that the new population is fist filled with individuals from the offspring. If the offspring does not contain enough individuals then the new population is filled up with individuals from the old population. If the offspring contains more individuals than the size of the population then the individuals are chosen uniformly at random.

Constructs a new instance of the ElitistReinserter.
sourcepub fn is_offspring_has_precedence(&self) -> bool
pub fn is_offspring_has_precedence(&self) -> bool
Returns true if the offspring should take precedence over better performing individuals from the old population.
sourcepub fn set_offspring_has_precedence(&mut self, value: bool)
pub fn set_offspring_has_precedence(&mut self, value: bool)
Sets whether the offspring should have precedence over better performing individuals from the old population.
sourcepub fn replace_ratio(&self) -> f64
pub fn replace_ratio(&self) -> f64
Returns the replace_ratio of this ElitistReinserter.
sourcepub fn set_replace_ratio(&mut self, value: f64)
