WebOct 1, 2005 · G. Marsaglia recently introduced a class of very fast xorshift random number generators, whose implementation uses three “xorshift” operations. They belong to a large family of generators based on linear recurrences modulo 2, which also includes shift-register generators, the Mersenne twister, and several others. Webnumber generator. The algorithm is based on work of George Marsaglia, a professor at Florida State University and author of the classic analysis of random number …

An MWC generator is a special form of Lehmer random number generator $${\displaystyle x_{n}=bx_{n-1}{\bmod {p}}}$$ which allows efficient implementation of a prime modulus $${\displaystyle p}$$ much larger than the machine word size. Normal Lehmer generator implementations … See more In computer science, multiply-with-carry (MWC) is a method invented by George Marsaglia for generating sequences of random integers based on an initial set from two to many thousands of randomly chosen seed … See more The output of a multiply-with-carry generator is equivalent to the radix-b expansion of a fraction with denominator p = ab − 1. Here is an example for the simple case of b = 10 and r = 1, so the result is a repeating decimal. Starting with See more Establishing the period of a lag-r MWC generator usually entails choosing multiplier a so that p = ab − 1 is prime. Then p − 1 will have to be factored in order to find the order of … See more A linear congruential generator with base b = 2 is implemented as $${\displaystyle x_{n+1}=(ax_{n}+c)\ {\bmod {\,}}2^{32},}$$ See more With multiplier a specified, each pair of input values x, c is converted to a new pair, If x and c are not … See more Continuing the above example, if we start with $${\textstyle x_{0}=34}$$, and generate the ordinary congruential sequence See more The MWC modulus of ab −1 is chosen to make computation particularly simple, but brings with it some disadvantages, notably that the period is at most half the modulus. There are several ways to generalize this, at the cost of more multiplications per iteration.
