Raphaël Maurin posted a new comment: Thank you for your replies. I just had a quick look at a review about random number generator in the chapter 7 of [1]. It is very interesting, and well detailed. They underline the fact that some usual generator proposed can be pretty bad, because the parametrization of the generators can be very important for the randomness. In my case, the random number generation is important but not crucial so I am not looking for something perfect but good enough. It seems that the linear congruential generators, as the one you use Klaus are adapted to my use. The parametrization the generators minstd_rand0 proposed in boost library (variation of the one you are using : minstd_rand) is based on the parametrization proposed by Park and Miller, which is cited as an efficient parametrization by [1]. It is described as a "a good minimal standard" random number generator. For people interested in more efficient generator, I think it is worth having a look at [1]. One last question Klaus, how did you test the random number generator exactly ? Thank you all for the help !
