CGAL::random_selection

Definition

random_selection chooses $$n items at random from a random access iterator range which is useful to produce degenerate input data sets with multiple entries of identical items.

#include <CGAL/random_selection.h>

template <class RandomAccessIterator, class Size, class OutputIterator, class Random>
OutputIterator	random_selection ( RandomAccessIterator first, RandomAccessIterator last, Size n, OutputIterator result, Random& rnd = default_random)
		chooses a random item from the range $$[first,last) and writes it to result, each item from the range with equal probability, and repeats this $$n times, thus writing $$n items to result. A single random number is needed from rnd for each item. Returns the value of result after inserting the $$n items. Precondition: Random is a random number generator type as provided by the STL or by Random.
