Hello,

I tried calling RandomArray.seed()

by calling RandomArray.get_seed() I get the seed number (x,y).

My problem is that x is always 113611 any advice?

Well, RandomArray.seed() gets its seed from the computer's time.

def seed(x=0,y=0):

"""seed(x, y), set the seed using the integers x, y;

Set a random one from clock if y == 0

"""

if type (x) != IntType or type (y) != IntType :

raise ArgumentError, "seed requires integer arguments."

if y == 0:

import time

t = time.time()

ndigits = int(math.log10(t))

base = 10**(ndigits/2)

x = int(t/base)

y = 1 + int(t%base)

ranlib.set_seeds(x,y)

As you can see, x won't change much if the difference in t is small.

Note, that in scipy_core, the random number facilities have been

completely rewritten. We now use the Mersenne Twister algorithm, which

uses 2496 bytes of state instead of 8 like RandomArray. On UNIX-type

systems with a /dev/urandom and also Windows, the default seed (all

2496 bytes of state) is drawn from the OS's "cryptographic PRNG" where

available.
