- *Alias:* None

- *Arguments:* None


**Description**


The ``mt19937`` keyword directs Dakota to use the Mersenne twister to
generate random numbers.  Additional information can be found on
wikipedia: http://en.wikipedia.org/wiki/Mersenne_twister.

*Default Behavior*

``mt19937`` is the default random number generator.  To specify it
explicitly in the Dakota input file, however, it must be specified in
conjuction with the ``rng`` keyword.

recommended.



**Examples**



.. code-block::

    method
      sampling
        sample_type lhs
        samples = 10
        seed = 98765
        rng mt19937
