On this page, I provide a C++ port of the famous Mersenne Twister pseudo-random number generator that has period 2¹⁹⁹³⁷-1. The algorithm and original C source code are designed by

I wrote a C++ port that takes advantage of the possibilities of the C++ programming language like inline member functions to enhance efficiency and the safety of classes. Probably because of this, the compiled code of this C++ version of the generator runs faster than the original C version, it runs even faster than the optimized C version written by Shawn Cokus (tested on a PC with Windows XP, a PC with Linux, and a Sun UltraSparc machine with Solaris, code was compiled with GNU C++ compiler and Borland C++ 5.5).

The code is 100% ISO standard C++ and no additional libraries are needed, so it can be compiled with any compiler that supports standard C++.
