| Summary : Auto-seeded Mersenne Twister PRNGs
|
Description :
The Mersenne Twister is a fast pseudorandom number generator (PRNG) that is
capable of providing large volumes (> 10^6004) of \"high quality\"
pseudorandom data to applications that may exhaust available \"truly\" random
data sources or system-provided PRNGs such as rand.
This module provides PRNGs that are based on the Mersenne Twister. There is
a functional interface to a single, standalone PRNG, and an OO interface
(based on the inside-out object model as implemented by the
Object::InsideOut module) for generating multiple PRNG objects. The PRNGs
are normally self-seeding, automatically acquiring a (19968-bit) random
seed from user-selectable sources. (_Manual_ seeding is optionally
available.)
* Random Number Deviates
In addition to integer and floating-point uniformly-distributed random
number deviates (i.e., \"irand\" and \"rand\"), this module implements the
following non-uniform deviates as found in _Numerical Recipes in C_:
* * Gaussian (normal)
* * Exponential
* * Erlang (gamma of integer order)
* * Poisson
* * Binomial
* Shuffling
This module also provides a subroutine/method for shuffling data based on
the Fisher-Yates shuffling algorithm.
* Support for 64-bit Integers
If Perl has been compiled to support 64-bit integers (do perl -V and look
for \'use64bitint=define\'), then this module will use a 64-bit-integer
version of the Mersenne Twister, thus providing 64-bit random integers and
52-bit random doubles. The size of integers returned by \"irand\", and used
by \"get_seed\" and \"set_seed\" will be sized accordingly.
Programmatically, the size of Perl\'s integers can be determined using the
\'Config\' module:
use Config;
print(\"Integers are $Config{\'uvsize\'} bytes in length\
\");
The code for this module has been optimized for speed. Under Cygwin, it\'s
2.5 times faster than Math::Random::MT, and under Solaris, it\'s more than
four times faster. (Math::Random::MT fails to build under Windows.)
