Xorshift128p class
Random number generator based on xorshift128+ algorithm by S. Vigna.
There were at least two known versions of this algorithm.
With constants 23, 17, 26:
- in paper - Apr 2014
- in JavaScript V8 engine
- on Wikipedia - 2021
With constants 23, 18, 5:
- in paper - Dec 2015
- in paper - May 2016
- in JavaScript xorshift library
"the most recent set of constants according to the author of the algorithm are: 23, 18, and 5. Those are theoretically better than the initial set of numbers" >>
This class uses the most recent constants: 23, 18, 5.
