The test program <a href="nondet_random_speed.cpp">nondet_random_speed.cpp</a>
measures the execution times of the
<a href="../../boost/nondet_random.hpp">nondet_random.hpp</a> implementation of the above
algorithms in a tight loop.  The performance has been evaluated on a
Pentium Pro 200 MHz with gcc 2.95.2, Linux 2.2.13, glibc 2.1.2.
