如何正确播种梅森倍捻机RNG？ [英] How to properly seed a mersenne twister RNG?

问题描述

这其实并不是这么简单，我首先想到的。

This is actually not as simple as I first thought.

在没有硬件RNG的，什么是可以播种Mersenne扭曲的最佳方式？

In the absence of a hardware RNG, what is the best way to seed a Mersenne Twister?

或者我应该说，什么是种子是用来产生一个梅森倍捻机RNG一种可接受的方式UUID的？

Or should I say, what is an acceptable way to seed a a Mersenne Twister RNG that is used to generate UUID's?

推荐答案

有是伪随机数生成器的此处包括的PRNG的正常播种节（见第3条），它使用的md5sum 和的/ dev /随机或的/ dev / urandom的生成种子。

There is a nice discussion of pseudo-random number generators here including a section on the proper seeding of PRNGs (see rule 3), which uses md5sum and /dev/random or /dev/urandom to generate seeds.

这还包括了一些PRNG算法的这是更容易code了大量的（小于10行code的），比MT，但可以说是一样好（很长时间并通过所有的随机性Dieharder测试）。

This also includes a number of PRNG alogrithms which are a lot easier to code up (< 10 lines of code) than the MT but are arguably just as good (long periods and pass all of the Dieharder tests for randomness).
