Hello, I thought that with the facilities from <random> we had good and well-defined ones -- but alas, only recently I realised that only say the Mersenne twister is well-defined in the standard, but roughly everything else is up to the implementer. Since reproducibility is crucial for us (as with most scientific applications), thus we need to implement ourselves the algorithms for 1. std::seed_seq 2. std::uniform_int_distribution 3. std::bernoulli_distribution (only for default p=0.5). Easiest would be to copy (and specialise) the gcc-implementations. I searched for it in the source-code, but couldn't find it: Where do I find the implementations for <random> ? Thanks for your help! Oliver
