RE: random numbers?
Sean, The implementation notes say Random uses the Wolfram rule 30 cellular automaton generator for integers. It uses a Marsaglia-Zaman subtract-with-borrow generator for real numbers. If that helps! But remember that Johnny von Neumann said something like: "Anyone who expects an arithmetical process to produce a random number is, of course, living in sin." David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: sean kim [mailto:sean_incali at yahoo.com] To: mathgroup at smc.vnet.net hello group. this is gonna sound silly. How do ppl make random number generators? is a random number generator like a routine that picks a given set of different number then goes back to the beginning and starts over? How does mathematica determine if a numbder is random? or is that even a right question to ask? I just wanted to know what the random generator is. and how it's used in Mathematica. maybe i'm asking alot. thanks in advance
