Detailed Description

An application examining the resulting arrangement of the Random Ball Cover data structure on 2-D data.

Note

The application requires further processing to extract the representative radii. This feature is not offered by the RBCConstruct class and is implemented on the CPU.

template<typename iterator >

void random_unique	(	iterator	xBegin,
		iterator	yBegin,
		iterator	rxBegin,
		iterator	ryBegin,
		size_t	n,
		size_t	rn
	)

Picks a number of elements uniformly at random without replacement from the input sequences.

The function implements a Fisher-Yates shuffle.

Parameters

[in]	xBegin	input iterator to the initial position of the database sequence with the x dimension.
[in]	yBegin	input iterator to the initial position of the database sequence with the y dimension.
[out]	rxBegin	output iterator to the initial position of the representatives sequence with the x dimension.
[out]	ryBegin	output iterator to the initial position of the representatives sequence with the y dimension.
[in]	n	number of database points.
[in]	rn	number of representative points.
