Hello,

I'm updating some algorithms and I need a tip for initialisation of the boost mersenne twister. I think the ctime is not a very good initialization. I think about a uuid value of the OS. I use also the non-deterministic generator, but I need an idea for the mersenne twister initialization.

Do you have an idea?

Well, you can use random_device to get a seed: random_device rng; mt19937 prgn1(rng()); // seed with one random value std::vector vec; for(int i = 0; i < NUM_SEED_WORDS; ++i) { vec.push_back(rng()); } seed_seq seed(vec); mt19937 prng2(seed); // seed with a fixed number of words mt19937 prng3(rng); // fill the entire initial state randomly In Christ, Steven Watanabe
