This page is OLD: OUTDATED (1999)

Standard Mersenne Twister and outputs, 99/10/29 version. 02/01/08, a (0,1)-version added.

Initialization routine sgenrand(seed) is modified, so that seed may be any unsigned long integer; even 0 is safe.

A lot of users of MT indicated us improvements of the code. Some recommended us to include "standard" C-code and its output sequences for the certification that their improvements do not change the output sequence.
