Marsaglia-multicarry
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 values. The main advantages of the MWC method are that it invokes simple computer integer … See more 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 … 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 … 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 b mod p. If p is a safe prime, then this is simple, and the order of b will be either p − … 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, $${\displaystyle x\leftarrow (ax+c)\,{\bmod {\,}}2^{32},\ \ c\leftarrow \left\lfloor {\frac {ax+c}{2^{32}}}\right\rfloor .}$$ 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 … See more
