RandomLib is a C++ interface to the Mersenne Twister random number generator, MT19937 and to the SIMD-oriented Fast Mersenne Twister random number generator, SFMT19937. It provides convenient access to random integers and reals at a variety of precisions. The emphasis in this implementation is on providing a reliable source of random numbers for scientific applications where there's a premium on accuracy, repeatability, portability, and ease of use. By default, this library uses SFMT's improved method for seeding the generator and it allows access to both the 32-bit and 64-bit versions of MT19937 and SFMT19937 and includes implementations of the SFMT19937 using SSE2 and AltiVec instructions.
