The Security Council consists of ten elected members, and five permanent members (China, the United States, France, the United Kingdom, and the Russian Federation). The current and past membership of the Security Council since 1946 can be found in the Members section.
A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG), is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers.ood statistical properties are a central requirement for the output of a PRNG. In general, careful mathematical analysis is required to have any confidence that a PRNG generates numbers that are sufficiently close to random to suit the intended use.
I created a simple algorithm to generate two-digit numbers using apparently random operations. 1  Start with a two digit number whose digits are d1d0. 2  Form a new digit r = 10 - (d1+d0) mod 10. 3  Form the three digit number s=d1rd0.  Let and form a new two digit number e1e0 where ei is the dith digit in t after the decimal.
