Here is a request for information.
Does anyone know of the whereabout of (code for)
a Random-Number Generator (Linear-Congruential or otherwise)
that produces output ``uniformally distributed''
amongst at least 2^96 objects?
i.e. integers: {1, ..., 2^96 }
The code can be in any language: Mathematica, C, APL, Maple, ....
Concerning Mathematica...
What are the technical specs on the RNG used by Mathematica?
What is its period?
How many distinct ``seeds'' are accepted by SeedRandom[]
and/or how many distinct starting-points for Random[]
are generated by seeding?
Indeed, does Mathematica even provide an RNG distinct from that
which may be built-in to the host-computer's operating system?
Please email replies to myself and timbourk at spirit.com.au,
posting to the group only if you think there is general interest.
Thanks,
Ross
