Detailed Description

  template<typename _RandomNumberEngine, size_t __k>
class std::shuffle_order_engine< _RandomNumberEngine, __k >"Produces random numbers by reordering random numbers from some base engine. The values from the base engine are stored in a sequence of size __k and shuffled by an algorithm that depends on those values.

Since
    C++11
