Hi!
I'm doing some work that involves MCMC / gibbs sampling ... and I need lots of random numbers, fast! I would also like it to be deterministic (after I give it a seed) so debugging / results is replicable. The best I have in mind right now ... is to seed something, impelment rc4, and go with that. Anyone have a better suggestion / something alread implemented in gambit?
Thanks!
Gambit implements srfi 27 out of the box which I have used in my Monte Carlo simulations of the Ising model (look on the dumping grounds). The behavior of the random number generator is identical to that on other implementations that I have tested on (larceny, PLT, scheme48) except for gauche which implements the Mersenne Twister thingy.
