MEANING OF PSEUDO-RANDOM NUMBERS

The methods commonly used to generate random numbers are not random processes. Random numbers are called psuedo-random numbers when they are generated by some deterministic process but they qualify the predetermined statistical test for randomness. The sequence of numbers generated by such process is completely determined by the input data (or the first random number) used for the method.

Mid-square method of generating Pseudo-random numbers: This is one of the commonly used methods to generate sequences of Pseudo-random numbers. The method works as follows:

Select a four-digit integer or seed to initialise the generator. The first random number is obtained from the seed in the following manner: The seed is squared, ...
