template<typename _T >

void ompl::GreedyKCenters< _T >::kcenters	(	const std::vector< _T > &	data,
		unsigned int	k,
		std::vector< unsigned int > &	centers,
		std::vector< std::vector< double > > &	dists
	)		[inline]

Greedy algorithm for selecting k centers.

Parameters:

data	a vector of data points
k	the desired number of centers
centers	a vector of length k containing the indices into data of the k centers
dists	a 2-dimensional array such that dists[i][j] is the distance between data[i] and data[center[j]]
