Gilles created RNG-32:
-------------------------

             Summary: Implement more generators
                 Key: RNG-32
                 URL: https://issues.apache.org/jira/browse/RNG-32
             Project: Commons RNG
          Issue Type: Wish
            Reporter: Gilles
            Priority: Minor


Commons RNG is focused on pure-Java implementations of standard deterministic generators.

Quite a few algorithms could be added, but priority is on fast generators that generate sequences of _pseudo-random_ numbers; i.e. the requirement is strong _uniformity_, but *not* strong _unpredictability_ (a.k.a. _true_ random numbers).
In particular, in Commons RNG, there is no provision for using an external entropy pool.

Beware that some well-known (and much used) algorithms have been proven to fail spectacularly on the uniformity requirement.

Would-be contributors should look at the {{commons-rng-core}} module for how to implement a generator, and at the {{commons-rng-examples}} module for how to test the uniformity requirement.
