Testing a Random Number Generator The first 1,000,000 numbers produced by the random number generator used in the General Purpose Systems Simulator (GPSS) were subjected to statistical tests. The tests are described and the results of the tests are presented. These particular tests indicate that the numbers are satisfactory. It is recommended that suitable tests be applied to all random numbers used in computer simulations. CACM February, 1967 Gorenstein, S.
