Despite the confusing URL, that is actually documentation for Numeric,
numpy's predecessor. You can see documentation for the current version
of numpy here:

Pseudorandom. The Mersenne Twister, to be precise.

"Monte Carlo" is more a general description than a specification of a
particular algorithm. There are many such methods. Which one are you
