Random-Number Seed
The seed of the random number generator can be set as follows:
Random:setSeed
On
Off
(
default =
off
)
Indicates whether a user-set seed should be used every time the
Pythia::init
routine is called. If off, the random number generator is initialized with its default seed at the beginning of the run, and never again. If on, each new
Pythia::init
call (should several be made in the same run) results in the random number being re-initialized, thereby possibly starting over with the same sequence, if you do not watch out.
Random:seed
(
default =
-1
;
maximum = 900000000
)
The seed to be used, if
setSeed
is on.
A negative value gives the default seed,
a value 0 gives a random seed based on the time, and
a value between 1 and 900,000,000 a unique different random number sequence.
