Detailed Description

template<class OrganismType>
class libevocosm::exponential_scaler< OrganismType >

Implements an exponential fitness scaling, whereby all fitness values are modified such that new fitness = (a * fitness + b) ^ n.

Parameters:

OrganismType

- The type of organism

libevocosm::exponential_scaler< OrganismType >::exponential_scaler	(	double	a_a = 1.0,
		double	a_b = 1.0,
		double	a_power = 2.0
	)		[inline]

Creates a new exponential scaler with a given set of parameters. The formula used is new_fitness = (a * fitness + b) ^ power.

Parameters:

a_a	- A multplier against the fitness
a_b	- Added to fitness before exponentiation
a_power	- Power applied to the value
