public interface RandomNumberGenerator

A (pseudo) random number generator is an algorithm designed to generate a sequence of numbers that lack any pattern.

It is very important to know that the sequence is not random at all and that it is completely determined by a relatively small set of initial values. Knowing the generation algorithm and the states can predict the next value, as the values are generated in a deterministic way.
