WebConstructs a mersenne_twister_engine object, and initializes its internal state sequence to pseudo-random values. The internal state sequence is seeded either applying a linear random generator on a single value (val) or using a seed sequence object (q).Parameters val A seeding value. An entire state sequence is generated from this value using a linear … WebI'd like to add that you should preferably have exactly one generator per thread since instantiating and seeding it takes time and the standard generators are not thread safe. I think std::random_device is not really reliable It should be able to tell you if it is via its entropy () function.
