Using boost::random as the RNG for std::random_shuffle

Question

I have a program that uses the mt19937 random number generator from boost::random. I need to do a random_shuffle and want the random numbers generated for this to be from th

Answer 1

I'm using tr1 instead of boost::random here, but should not matter much.

The following is a bit tricky, but it works.

#include 
#include 


std::tr1::mt19937 engine;
std::tr1::uniform_int<> unigen;
std::tr1::variate_generator >gen(engine, unigen);
std::random_shuffle(vec.begin(), vec.end(), gen);
