      k+1 is a floating pointing number the random number in the interv al [0,1). The initial value of S k, S 0, is called the initial seed for the generator. If c=0 and (g mod 8) = 3 or 5, then the generator has a period 2M-2. If c 0 and (g mod 4)=1 andc is odd, then the period is 2M.

      General Random Number Generation Algorithm In each of the three methods: Each generator has a state Y n, which has one or more variables, that can be advanced by some algorithm Y n+1 = f(Y n) from some initial value Y 0. There is an output process x n = g(Y n) that generates an approximate Uniform[0,1) random number x n.

This makes the multidimen-sional array generation as efficient as possible because the total number of random values is generated as efficiently as possible and the time required for partitioning is negligible.

It is the result of a separate, independent, random number generator based on bitwise logical operations. The floating-point fraction of each zi is XORed with j to produce the result returned by the generator.
