A Pseudorandom number sequence is a sequence of numbers that has been computed by some defined arithmetic process but is effectively a random number sequence for the purpose for which it is required. In Mathematics, a sequence is an ordered list of objects (or events Random number may refer to A number generated for or part of a set exhibiting Statistical randomness.
Although a pseudorandom number sequence in this sense often appears to lack any definite pattern, any pseudorandom number generator with a finite internal state will repeat after a very long sequence of numbers. This can be proved using the pigeonhole principle. The pigeonhole principle, also known as Dirichlet's box (or drawer) principle, states that given two Natural numbers n and
An other definition :
A set of values or elements that is statistically random, but it is derived from a known starting point and is typically repeated over and over. A Binary sequence (BS is a sequence of N bits a_j for j=01N-1 i A pseudorandom process is a process that appears random but is not A pseudorandom number generator ( PRNG) is an Algorithm for generating a sequence of numbers that approximates the properties of random numbers Pseudo-random numbers provide necessary values for processes that require randomness, such as creating test signals or for synchronizing sending and receiving devices in a spread spectrum transmission. It is called "pseudo" random, because the algorithm can repeat the sequence, and the numbers are thus not entirely random.
