Fitness scaling for a population. More...
As a population converges on a definitive solution, the difference between fitness values may become very small. That prevents the best solutions from having a significant advantage in reproduction. Fitness scaling solves this problem by adjusting the fitness values to the advantage of the most-fit chromosomes.
|OrganismType||- The type of organism|
|virtual libevocosm::scaler< OrganismType >::~scaler||(||)||
A virtual destructor. By default, it does nothing; this is a placeholder that identifies this class as a potential base, ensuring that objects of a derived class will have their destructors called if they are destroyed through a base-class pointer.
|virtual void libevocosm::scaler< OrganismType >::scale_fitness||(||vector< OrganismType > &||a_population||)||
The scale_fitness method can adjust the fitness of a population to make it more likely that the "best" (whatever that menas) organisms have the best chance of reproduction.
|a_population||- A population of organisms|
Implemented in libevocosm::null_scaler< OrganismType >, libevocosm::linear_norm_scaler< OrganismType >, libevocosm::windowed_scaler< OrganismType >, libevocosm::exponential_scaler< OrganismType >, libevocosm::quadratic_scaler< OrganismType >, libevocosm::sigma_scaler< OrganismType >, and libevocosm::linear_norm_scaler< function_solution >.
