Dear all, Using the following (slightly manipulated) sample code of Boost.Random, I'm always gettig the same sequence: boost::mt19937 rng; boost::uniform_int<> six(1,6); boost::variate_generator<boost::mt19937, boost::uniform_int<> > die(rng, six); for(size_t i = 0; i < 10; ++i) cout << die() << " "; I know that this is the consequence of the fact that the generators are deterministic ones, plus another fact that they start using the same seed. This behaviour, however, is not that much desirable, and I'm seaking some sort of good random seed. Any suggestions? TIA and Merry Christmas, --Hossein __________________________________ Do you Yahoo!? Yahoo! Mail - You care about security. So do we. http://promotions.yahoo.com/new_mail
