Detailed Description

template<class BV>
class bm::random_subset< BV >

Class implements algorithm for random subset generation.

Implemented method tries to be fair, but doesn't guarantee true randomeness or absense of bias.

Performace note: Class holds temporary buffers and variables, so it is recommended to re-use instances over multiple calls.
