Short: Best Random Number Generator (PPC+68k) Author: George Masaglia, Arif Zaman, David LaSalle, Jim Butler Uploader: info@ar-kleinert.de Type: dev/c ************************************************************************* This random number generator originally appeared in "Toward a Universal Random Number Generator" by George Marsaglia and Arif Zaman. Florida State University Report: FSU-SCRI-87-50 (1987) It was later modified by F. James and published in "A Review of Pseudo- random Number Generators" THIS IS THE BEST KNOWN RANDOM NUMBER GENERATOR AVAILABLE. (However, a newly discovered technique can yield a period of 10^600. But that is still in the development stage.) It passes ALL of the tests for random number generators and has a period of 2^144, is completely portable (gives bit identical results on all machines with at least 24-bit mantissas in the floating point representation). The algorithm is a combination of a Fibonacci sequence (with lags of 97 and 33, and operation "subtraction plus one, modulo one") and an "arithmetic sequence" (using subtraction). ======================================================================== This C language version was written by Jim Butler, and was based on a FORTRAN program posted by David LaSalle of Florida State University. ************************************************************************* The Amiga 68k/PPC version comes with both, makefiles for 68k and PPC, and test programs for both CPUs.
