Public Member Functions
void	clear ()
	Clears the map.
void	operator() (const eoPop< EoType > &_pop)
	Update or create the dominance map.
void	remove (unsigned i)
	Removes the domination info for a given individual, thus nothing dominates it and it dominates nothing.
void	setup (const eoPop< EoType > &_pop)
	Create domination matrix from scratch.
std::vector< double >	sum_dominators () const
	For all elements, returns the no.
std::vector< double >	sum_dominants () const
	For all elements, returns the number of elements that the element dominates Thus: higher is better It returns a std::vector<double> cuz that makes subsequent manipulation that much easier.

Detailed Description

template<class EoType>
class eoDominanceMap< EoType >

eoDominanceMap, utility class to calculate and maintain a map (std::vector<std::vector<bool> >) of pareto dominance statistics.

It is set up such that

if map[i][j] == true then i dominates j

The dominance map can be used to perform pareto ranking (eoParetoRanking) or non dominated sorting. For the latter, the remove() member function might come in handy.

Todo:

make it an eoStat?

template<class EoType> void eoDominanceMap< EoType >::setup (  const eoPop< EoType > &  _pop  )  [inline]

Create domination matrix from scratch. Complexity O(N^2) Definition at line 81 of file eoDominanceMap.h. Referenced by eoDominanceMap< EOT >::operator()().

template<class EoType> std::vector<double> eoDominanceMap< EoType >::sum_dominators (   )  const [inline]

For all elements, returns the no. of elements that dominate the element Thus: lower is better (and 0 is the front). It returns a std::vector<double> cuz that makes subsequent manipulation that much easier Definition at line 118 of file eoDominanceMap.h. Referenced by eoParetoRanking< EOT >::calculate_worths().
