Get random subset of input vector. More... | |
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.
