Description of MCV, a pseudo-random number generator

The need for random-numbers in simulation in nuclear physics, communications, risk theory, queue systems, industrial organization and many other related and similar topics is beyond question. Sooner or later the calculation part of these problems grows beyond human powers and a computer has to be involved. When using this instrument, spending only microseconds on the arithmetic operations, we cannot spend seconds on generating random numbers with the classical tools: coins, dice, tombolas or something like that. However, many other methods are known which can be adapted for computer applications.
