Subject [jira] [Commented] (RNG-32) Implement more generators
Date Mon, 01 Apr 2019 22:09:00 GMT


Gilles commented on RNG-32:

bq. Do you think working on this issue requires deep mathematical knowledge?

No (we "only" port/implement existing algorithms; we do not try to design new RNGs).
Unit tests are required to prove that the port is correct.

See the "dev" ML archive for a [recent discussion|]
with a GSoC candidate.

> 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.
