#Pseudo random generator algorithm generator
Std::random_device is a non-deterministic uniform random bit generator, although implementations are allowed to implement std::random_device using a pseudo-random number engine if there is no support for non-deterministic random number generation. Algorithm AS 183 An Efficient and Portable Pseudo-random Number Generator By B. Its Period is not as long as the Mersenne Twisters but its still decent. Compared with the random library in Java it is about 30 faster and provides better results.

However there is a period, n, in a sequence. If you look for an algorithm, that passes all statistical tests, but is still fast you could try the Xorshift-Algorithm. Newer "Minimum standard", recommended by Park, Miller, and Stockmeyer in 1993 ģ2-bit Mersenne Twister by Matsumoto and Nishimura, 1998 Ħ4-bit Mersenne Twister by Matsumoto and Nishimura, 2000 Ģ4-bit RANLUX generator by Martin Lüscher and Fred James, 1994 Ĥ8-bit RANLUX generator by Martin Lüscher and Fred James, 1994 From each number of the sequence of pseudo-random numbers a new number is computed (usually we work with integers). number generator (PCNG) that exhibits both chaotic properties and pseudo-randomness is a good candidate for creating the cryptographic key stream for encryption.

Discovered in 1969 by Lewis, Goodman and Miller, adopted as "Minimal standard" in 1988 by Park and Miller
