/* The Mersenne Twister code is currently commented out due to
|
|
|
|
|
|
|
|
(1) Simple user specified seeds lead to really bad sequences for
|
|
|
|
nearly 100000 random numbers.
|
|
|
|
(2) open(), read(), and close() are not properly declared via header
|
|
|
|
files.
|
|
|
|
(3) The global index i is abused and causes unexpected behavior with
|
|
|
|
GET and PUT.
|
|
|
|
(4) See PR 15619.

The algorithm was taken from the paper :

(1) The congruential generator x(n)=69069*x(n-1)+1327217885 with a period

As I hoped, several suggestions have led to
|
|
|
|
improvements in the code for RNG's I proposed for
|
|
|
|
use in C. (See the thread "Random numbers for C: Some
|
|
|
|
suggestions" in previous postings.) The improved code
|
|
|
|
is listed below.
|
|
|
|
|
|
|
|
A question of copyright has also been raised. Unlike
|
|
|
|
DIEHARD, there is no copyright on the code below. You
|
|
|
|
are free to use it in any way you want, but you may
|
|
|
|
wish to acknowledge the source, as a courtesy.
