[Boost-users] Newbie question: Random numbers.

I have a simple question, is there a very fast and effecient way to generate random numbers that are fast on the fly. The numbers are really randomize and distorted... /*************************************************** * generates a random number between a and b * * @param a the starting range * * @param b the integer ending range * * @return N such that a <= N <= b * **************************************************/ template <class T> T randint(const T& a, const T& b) { BOOST_STATIC_ASSERT(boost::is_integral<T>::value); assert (b >= a); typedef boost::minstd_rand base_generator_type; typedef boost::uniform_int<> distribution_type; typedef boost::variate_generator gen_type; base_generator_type generator(boost::numeric_cast<unsigned long>(clock())); gen_type ran_gen(generator, distribution_type(a, b)); for (int i = 0; i < 30000; ++i) generator.seed(boost::numeric_cast<unsigned long>(clock())); return ran_gen(); } This works but is super slow... are there effective ways to do it... Thanks.
