template<class AbstractInstance>
class Weighted< AbstractInstance >

Weighted Fitness Function used from evaluating the instances in EIG. This functions performs a linear weighted sum of the performance fitness of the instances and their novelty to calculate their final fitness.

Template Parameters

AbstractInstance

Constructor & Destructor Documentation

Weighted()

template<class AbstractInstance >

Weighted< AbstractInstance >::Weighted	(	const float &	fRatio,
		const float &	dRatio
	)

Construct a new Weighted object with the corresponding fitness ratio and diversity ratio.

Template Parameters

AbstractInstance

Parameters

fRatio	Weight of the fitness in the final fitness.
dRatio	Weight of the novelty in the final fitness.

Member Function Documentation

computeFitness()

template<class AbstractInstance >

void Weighted< AbstractInstance >::computeFitness

(

vector< AbstractInstance > &

solutions

)

Computes the actual fitness of the solutions based on the fitness pre-defined in the instances and their diversity.

The selection of different ratios determine whether the generated instances will be completely biased (and well clustered) or more dispersed

Template Parameters

AbstractInstance

Parameters

solutions

getFAndNRatios()

template<class AbstractInstance >

std::tuple<float, float> Weighted< AbstractInstance >::getFAndNRatios ( )

inline

Returns a tuple containing the fitness and novelty ratio in that order!

Returns

std::tuple<float, float>
