Alex D Herbert commented on RNG-111:
------------------------------------
I think at the moment there is a bit of inconsistency where the name of the
author appears in one generator but not another. Here are some points:
* None of any of the other enum values specify the author in their name
* Doty-Humphrey named his generator sfcNN (NN is for the state size)
* Bob Jenkins did not explicity name his generator but called it 'small fast'
* Doty-Humphrey named Jenkins generator jsf
Stripping the author would be:
* SFC_32
* SFC_64
* SF_32
* SF_64
At least this shows the two are related. I would vote for this option and deal
with name clashes in the future.

> Project: Commons RNG
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.3
> Reporter: Alex D Herbert
> Assignee: Alex D Herbert
> Priority: Minor
> Fix For: 1.3

>
> Implement Bob Jenkins' Small/Fast Chaotic PRNG.
> [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).
