The Additive Lagged-Fibonacci Generator (ALFG) is: In recent years the ALFG has become a popular generator for serial as well as scalable parallel machines because it is easy to implement, it is cheap to compute and it does well on standard statistical tests , especially when the lag k is sufficiently high (such as k = 1279). 2.2.2 Lagged-Fibonacci Generators (LFG) The name of the generator comes from the Fibonacci sequence. quarter the length of the corresponding ALFG [27], it has empirical November 2018. Also, this is called a "two-tap" generator, in that you are using 2 values in the sequence to generate the pseudorandom number. parallelized by varying a parameter in the underlying recursion. parallel computing is that a parameterization analogous to that of the $ python lagged.py 6 1 4 4 3 9 0 4 8 1. Instead the ALFG can be parameterized through its initial values It's a "lagged" generator, because "j" and "k" lag behind the generated pseudorandom value. The Additive Lagged-Fibonacci Generator (ALFG) [12] is a recurrence-based generator that is parameterized by the values or lags ` and k and an initial state array of length ` and width m. The transition function xn = xn−` +xn−k (mod 2 m) (1) describes how a new value xn is derived from two previous values xn−` and xn−k in the sequence. Cite . different full-period cycles [28]. If you wish to perform a statistical analysis of the results, a sample of 30 runs should be sufficient. A Lagged Fibonacci generator (LFG) is an example of a pseudorandom number generator. Trying to make an efficient Fibonacci sequencer in Python. If the operation used is addition, then the generator is described as an Additive Lagged Fibonacci Generator or ALFG, if multiplication is used, it is a Multiplicative Lagged Fibonacci Generator or MLFG, and if the XOR operation is used, it is called a Two-tap Generalised Shift Feedback Register or GFSR. The maximal period of multiplicative lagged Fibonacci generator, however, is shorter than that of additive lagged Fibonacci generator:MLFG=2b−3(2p1−1). # Fibonacci sequence is series in which each successive number is the sum of the previous two numbers. We study the suitability of the additive lagged-Fibonacci pseudorandom number generator for parallel computation. It uses the modulus 2 and by default the "lags" 418 and 1279. These are based on a generalisation of the Fibonacci sequence. However, some care For a complete discussion, see .
