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 ;-)

PS did anyone receive the mail that I sent yesterday about syllogisms?

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:
