The Mersenne twister is a pseudorandom number generator developed by Makoto
Matsumoto and Takuji Nishimura that is based on a matrix linear recurrence over
a finite binary field. It provides for fast generation of very high quality
pseudorandom numbers. The source for the C code can be found here:
This library provides a purely functional binding to the 64 bit classic
mersenne twister, along with instances of RandomGen, so the generator can be
used with System.Random. The generator should typically be a few times faster
than the default StdGen (but a tad slower than the impure 'mersenne-random'
library based on SIMD instructions and destructive state updates. .
