some serious defects. For example, if LCG is used as the point coordinate of the n-dimensional space, these points are located at most on the M1/n superplane (marsaglia theorem ), this is because of the successive Association of x (n) values.
Another problem is that if M is set to 2, the generated low sequence cycle is much smaller than the overall.In general, the minimum N bits in Base B of the output sequence, BK = m (K is an integer), and the maximum period bn.In some cases, LCG has good app

The Mersenne twister algorithm is a good choice if you need high quality pseudorandom numbers and sufficient memory (about 2KB). Mersenne Twister produces a random number of masses almost more than any LCG. However, the implementation of General Mersenne Twi

Php generates the random number mt_rand () rand () mt_srand () function. Mt_rand () returns a random integer using the mersennetwister algorithm. Syntax mt_rand (min, max) indicates that if the optional parameters min and max are not provided, mt_rand () returns the pseudo value between 0 and rand_max with mt_rand () and returns a random integer using the mersenne twister algorithm.

generates a random float uniformly in th e semi-open range [0.0, 1.0]. Python uses the Mersenne Twister as the core generator. It produces 53-bit precision floats and has a period of 2**19937-1. The underlying implementation in C is both fast and threadsafe. The Mersenne Twister is one of the most extensively tested random number generators in existence. However, being completely deterministic, it is not s
