  • Random number — may refer to:* A number generated for or part of a set exhibiting statistical randomness. * A random sequence obtained from a stochastic process. * An algorithmically random sequence in algorithmic information theory. * The output of a random… …   Wikipedia

  • Random number table — Random number tables have been used in statistics for tasks such as selected random samples. This was much more effective than manually selecting the random samples (with dice, cards, etc.). Nowadays, tables of random numbers have been replaced… …   Wikipedia

  • Pseudorandom number sequence — 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. Although a pseudorandom number sequence in… …   Wikipedia

  • Random number generation — A random number generator (often abbreviated as RNG) is a computational or physical device designed to generate a sequence of numbers or symbols that lack any pattern, i.e. appear random. Computer based systems for random number generation are… …   Wikipedia

  • Random number generator attack — The security of cryptographic systems depends on some secret data that is known to authorized persons but unknown and unpredictable to others. To achieve this unpredictability, some randomization is typically employed. Modern cryptographic… …   Wikipedia

  • Hardware random number generator — This SSL Accelerator computer card uses a hardware random number generator to generate cryptographic keys to encrypt data sent over computer networks. In computing, a hardware random number generator is an apparatus that generates random numbers… …   Wikipedia

  • Park–Miller random number generator — The Park–Miller random number generator (or the Lehmer random number generator) is a variant of linear congruential generator that operates in multiplicative group of integers modulo n. A general formula of a random generator (RNG) of this type… …   Wikipedia

  • Random sequence — A random sequence is a kind of stochastic process. In short, a random sequence is a sequence of random variables. Random sequences are essential in statistics. The statistical analysis of any experiment usually begins with the words let X 1,...,… …   Wikipedia

  • Random permutation — A random permutation is a random ordering of a set of objects, that is, a permutation valued random variable. The use of random permutations is often fundamental to fields that use randomized algorithms. Such fields include coding theory,… …   Wikipedia

  • Random variate — A random variate is a particular outcome of a random variable: the random variates which are other outcomes of the same random variable would have different values. Random variates are used when simulating processes driven by random influences… …   Wikipedia

  • Halton sequence — In statistics, Halton sequences are sequences used to generate points in space for numerical methods such as Monte Carlo simulations. Although these sequences are deterministic they are of low discrepancy, that is, appear to be random for many… …   Wikipedia
