> [A small noncryptographic PRNG|http://burtleburtle.net/bob/rand/smallprng.html]
> Variants are provided for 32-bit and 64-bit output. The generators use bit shifts to avalanche state and many variants are provided for different shift combinations. However there is a recommended variant that has been more extensively tested. A seeding routine is provided to ensure that generators with short cycles are avoided.
> This generator has no name but appears in PractRand as JSF (Jenkins Small Fast).
