Standard and portable pseudo random number generator based on seed in C++

Question

If i want to start building a PRNG in C++ what are the best bricks for the job?

are there any standardize and portable libraries with a predictable behaviour ( with a seed ) and pseudo randomic?

Answer 1

When you say "portable" I assume you want the same sequence of random numbers given the same seed, no matter which platform they're compiled for. Pseudo-random number generators should provide the same sequence as long as they're based on the same algorithm. I think boost::random is your best bet, it's a good random number generator (better than rand in many cases) with predictable behavior across platforms.

Answer 2

C++11 offers a host of portable random-number generators. This was driven by the folks at Fermilab, who do heavy-duty simulations of subatomic particle interactions, often involving distributing work through a network to many computers.
