The invention realizes powerful ways to select multipliers of excellence with greatly improved statistical performances in their generation of uniform and independent random numbers. Related two inventions for new designs of the generator (d,z) are presented at the same time, as strongly facilitative for the application of advocated extended spectral tests, by exploiting specific structures of moduluses formed by two odd-prime-powers so as to realize improved periodic structures that are set conveniently out of tune avoiding harmful resonances. | 01-08-2015 |
