Edit ``Mersenne Twister''
The Mersenne Twister is a pseudorandom number generation *(algorithm) created by Makoto Matsumoto. There is a <a href="http://cybertiggyr.com/gene/jmt/jmt.html#mersenne-twister-home">Mersenne Twister home page</a>, and a <a href="http://en.wikipedia.org/wiki/Mersenne_twister">Wikipedia entry</a>. The Mersenne Twister algorithm has a large period (something like 2<sup>19,937</sup> - 1), and it is advertised as fast.</p> There are two main portable implementations: <ul> <li>_(MT19937) is a portable version of _(CMUCL)'s random number generator. It's faster than _(jmt.lisp), but significantly slower than the built-in :(CLHS "random") function on all implementations it's been tested with. It's in the public domain.</li> <li>_(jmt.lisp) is another implementation of the Mersenne Twister. It's slower than _(MT19937), but it's still a good implementation. In particular, _(MT19937) may have a few bugs from the move to portability. It's under the LGPL.</li> </ul> <hr> *(statistics)
