This paper concerns with almost all kinds of generators such as the linear, nonlinear and inversive congruential methods, fibonacci and tausworthe sequences, add-with-carry and subtract-with-borrow methods, multiple prime generator and chaotic mapping 目前国际上关于随机数有很多热门的理论和方法,除了传统的线性同余法,还有非线性同余法、fibonacci、tausworthe序列、进位加?借位减发生器法等。
