the method from l'Ecuyer is already used in the texas instruments graphic calculators. But they don't seem to have patented it (I don't know how to check that). Anyway I agree to have more RNGs which can be useful for statistics simulations or kryptography. And I would like to know how one can play with the bacteria ;-) Alain PS did anyone receive the mail that I sent yesterday about syllogisms?

Hi guys
Konstantin who is a biologist developed for a "bacteria" eating monster simulation system, two new random number generators. I think that this is great because we need more random generators :)
- Combined Random Number Generator is based on the algorithm described by PIERRE L'ECUYER in "Efficient and Portable Combined Random Number Generators" [Communications of the ACM, June 19, Volume 31, Number 6, pp. 742-749, references p.774].
- ExpInvConGen is an explicit inversive congruential generator, constructed according to "Good random number generators are (not so) easy to find" by P. Hellekalek (1998) and extended euclidean algorithm.
I plan to package them and publish them in SciTalk with their own configuration. But I wanted to know what you think.
Great !
Maybe better to integrate them in Sci-talk with the existing Random Number Generator (RNG). We have already 5 RNGs. I'm working on refactoring the RNG and distributions in Sci-Talk, because there is some redundancy until now: https://groups.google.com/forum/#!topic/scismalltalk/zXEyeGvTmJk
