<h3 class="section">D.12 <code>mtwist</code></h3>

<p>The <code>mtwist</code> library interfaces to a random number generator
<a name="index-random-numbers-780"></a>based on the Mersenne Twistor algorithm. The algorithm has good
properties but is not meant to be cryptographically secure. The
library functions are of the form

<pre class="example">     library('mtwist',f)
</pre>
   <p class="noindent">where <code>f</code> is one of the followng character strings.

<pre class="example">     bern   u_cont   u_disc   u_path   u_enum   w_disc   w_enum
</pre>
   <p>Formally they are not mathematical functions because their results
depend on a pseudo-random number that is not uniquely determined by
their arguments. The numbers are generated deterministically in a
sequence starting from a seed derived from the system clock at the
time <code>avram</code> is launched, and each call uses the next number
in the sequence. In so doing, it simulates a random draw from a
uniformly distributed population.
