Detailed Description

Implements the Additive approximation properties of sets.

The additive approximation measures which value must be subtracted from a reference set until it becomes dominated by a target set.

The implemented least contributor algorithm calculates the point That is approximated best by the remaining points. Thus the reference set is the full set and the target sets all in which one point is removed.

◆ init()

template<class random >
void shark::AdditiveEpsilonIndicator::init ( std::size_t  ,
std::size_t  ,
random &

◆ leastContributor()

template<typename ParetoFrontType , typename ParetoArchive >
std::size_t shark::AdditiveEpsilonIndicator::leastContributor ( ParetoFrontType const &  front,
ParetoArchive const &   
) const

Given a pareto front, returns the index of the point which is the least contributer.

The archive has no effect on the volume as the archive is dominating all points in the front
