The period depends upon the choice of M, a, b, and the starting `seed' rl, but it is never more than M. mannella rita giuliana

NettetMany practiced and proposed methods for the generation of pseudo-random numbers for use in Monte Carlo calculation can be expressed in the following way: One chooses an integer P, the base; an integer λ, the multiplier, prime to P; and an integer μ, the increment, less than P ( μ is frequently, but not always, zero). References Nettet16. mar. 2024 · One way is to use the so called Lehmer random number method. It generates a sequence of random numbers in your spreadsheet that stays the same until you change the "seed number", a number you choose yourself and will recreate a different random sequence for each seed number you choose.
