The Mersenne Twister is a general-purpose pseudorandom number generator (PRNG) developed in 1997 by Makoto Matsumoto (松本 眞) and Takuji Nishimura (西村 拓士). [1] [2] Its name derives from the choice of a Mersenne prime as its period length. The Mersenne Twister was designed specifically to rectify most of the flaws found in older PRNGs.
Mersenne Twister (MT) 1998 M. Matsumoto and T. Nishimura [25] Closely related with LFSRs. In its MT19937 implementation is probably the most commonly used modern PRNG. Default generator in R and the Python language starting from version 2.3. Xorshift: 2003 G. Marsaglia [26] It is a very fast sub-type of LFSR generators.
In cryptography, CryptMT is a stream cipher algorithm which internally uses the Mersenne twister.It was developed by Makoto Matsumoto, Mariko Hagita, Takuji Nishimura and Mutsuo Saito and is patented.
The 1997 invention of the Mersenne Twister, [9] in particular, avoided many of the problems with earlier generators. The Mersenne Twister has a period of 2 19 937 − 1 iterations (≈ 4.3 × 10 6001 ), is proven to be equidistributed in (up to) 623 dimensions (for 32-bit values), and at the time of its introduction was running faster than ...
Free Pascal uses a Mersenne Twister as its default pseudo random number generator whereas Delphi uses a LCG. Here is a Delphi compatible example in Free Pascal based on the information in the table above. Given the same RandSeed value it generates the same sequence of random numbers as Delphi.
The program is designed to securely erase a hard disk until its data is permanently removed and no longer recoverable, which is achieved by overwriting the data with pseudorandom numbers generated by Mersenne Twister or ISAAC.
An xorshift+ generator can achieve an order of magnitude fewer failures than Mersenne Twister or WELL. A native C implementation of an xorshift+ generator that passes all tests from the BigCrush suite can typically generate a random number in fewer than 10 clock cycles on x86, thanks to instruction pipelining.

In some PRNGs, such as the Mersenne Twister, the state is large, more than 2048 bytes. In other PRNGs, such as xorshift , s t a t e i {\displaystyle \mathrm {state} _{i}} and n u m i {\displaystyle \mathrm {num} _{i}} are one and the same (and so the state is small, just 4, 8, or 16 bytes, depending on the size of the numbers being generated).
