Creates a new sigma scaler

Member Function Documentation

template<class OrganismType >
virtual void libevocosm::sigma_scaler< OrganismType >::scale_fitness ( vector< OrganismType > &  a_population) [inline, virtual]

Performs sigma scaling, which maintains selection pressure over the length of a run, thus minimizing the affects of convergence on reproductive selection. The function adjusts an organism's fitness in relation to the standard deviation of the population's fitness.

a_population- A population of organisms

Implements libevocosm::scaler< OrganismType >.
