News:

TinyMT is released. (2011/06/20)
MTGP is released(2009/11/17)
we released SIMD-oriented Fast Mersenne Twister (SFMT). SFMT is roughly twice faster than the original Mersenne Twister, and has a better equidistibution property, as well as a quicker recovery from zero-excess initial state. Click here! (2007/1/31)

If you send an email when you use Mersenne Twister (MT), it will encourage us - even if we are unable to reply to all the messages we receive.
Please let us know when you find any problems.

Caution: Mersenne Twister is basically for Monte-Carlo simulations - it is not cryptographically secure "as is". Please read FAQ.
