The following was posted on info-mac, and I thought it would be of interest
to readers of this rnd number discussion (esp those who want code).

 Arif Zaman and George Marsaglia of the Supercomputer Computations
Research Institute at Florida State University recently developed a
random number generator that has special features. They wrote an
IBM/PC implementation of it in assembler and C, called ULTRA101.ZIP,
which they uploaded to the network.

     I downloaded that file and converted their C program to run on the
macintosh. I am submitting a Stuffit 1.5.1 archive containing this
conversion and also the original IBM submission. I don't know in which
directory this should be placed. Maybe, app or lang. It would be nice
to have a "math" directory to put it in.

     I read about their program from the listserver PCTECH-L@TREARN
when Jim Ritterbusch sent the following message on April 13, which
I will quote:

A while ago, I sent a message searching for a random number generator that
was a recent development in that it had a humongous period. A few of you
replied directly expressing interest when and if I was able to get the
information.

I have finally located it. I replied directly to those that asked, but in
case any others of you are still lurking and waiting for the answer, here
it is.

It was developed by Arif Zaman and George Marsaglia of the Supercomputer
Computations Research Institute at Florida State University. It has a
period of over 10^356 (or about 10^250 random numbers for each atom in
the universe !).

An IBM/PC version including source code for assembler and C is available
as the file ULTRA101.ZIP. I was able to anonymous ftp this from
garbo.uwasa.fi in /pub/msdos/math. According to archie, it is also
available at rigel.acs.oakland.edu in /pub/msdos/math.

Don't forget to use binary mode in your ftp as well as your download to
your PC. Good luck with it and enjoy.

Ain't the Internet grand!
