ACORN is still alive in 2019, and performing well.

... should include links to

1.Wikipedia page ACORN PRNG

and

2.to ACORN web site http://acorn.wikramaratna.org

:I am glad to hear it. If you are an expert on this generator, please feel free to add as much material as you deem appropriate. All the best, --[[User:Carl McBride | Carl McBride]] ([[User_talk:Carl_McBride |talk]]) 09:40, 8 May 2019 (CEST)

:: I added the web site to ACG page, and added a clarification to your 'Random Numbers' page based on your 2007 statement that ACG is the same as ACORN

However there is an important question ! is ACG equivalent to ACORN ? Are you sure ?
If these are in fact two different PRNGs then we would need a separate ACORN page, and a new line in 'random numbers'

:This is a good question that should be looked into. I think the best thing to do is to start a new page dedicated to ACORN, and if ACG is indeed equivalent to ACORN, then the existing ACG page can be very easily converted into a redirect page to ACORN. All the best,--[[User:Carl McBride | Carl McBride]] ([[User_talk:Carl_McBride |talk]]) 09:45, 22 May 2019 (CEST)

::done; created ACORN, mentioned not to be confused
The actual history of this confusion should also bbe looked into. I mention this for future work (not me)

78.115.82.117: create ACORN page

'''AC'''O'''RN''' is the '''Additive Congruential Random Number''' generator <ref>[http://dx.doi.org/10.1016/0021-9991(89)90221-0 R. S. Wikramaratna "ACORN—A new method for generating sequences of uniformly distributed Pseudo-random Numbers", Journal of Computational Physics '''83''' pp. 16-31 (1989)]</ref> introduced by Roy Wikramaratna in 1989.

Advantages of ACORN (from http://ACORN.wikramaratna.org/critique.html):
<li>extremely light-weight code (a few lines) with reproducible results in any high-level language and on any platform; </li>
<li>theoretical convergence is mathematically proven; </li>
<li>all current empirical test suites for PRNGs are passed; </li>
<li>can be easily extended to give sequences with longer period length, and improved statistical performance over higher dimensions and with higher precision.</li>

==Web site==
The web site [http://ACORN.wikramaratna.org ACORN.wikramaratna.org] describes ACORN in detail and provides complete references.
