<h2>Random-Number Seed</h2>
The seed of the random number generator can be set as follows:
<p/><code>flag </code><strong> Random:setSeed </strong>
(<code>default = <strong>off</strong></code>)<br/>
Indicates whether a user-set seed should be used every time the
<code>Pythia::init</code> 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 <code>Pythia::init</code>
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.
<p/><code>mode </code><strong> Random:seed </strong>
(<code>default = <strong>-1</strong></code>; <code>maximum = 900000000</code>)<br/>
The seed to be used, if <code>setSeed</code> is on.<br/>
A negative value gives the default seed,<br/>
a value 0 gives a random seed based on the time, and<br/>
a value between 1 and 900,000,000 a unique different random number
sequence.
<p/>
For more on random numbers see <a href="RandomNumbers.html" target="page">here</a>.
This includes methods to save and restore the state of the generator,
and some preprogrammed methods to generate non-uniform random numbers.
