Definition of pseudorandom in English:



  • (of a number, a sequence of numbers, or any digital data) satisfying one or more statistical tests for randomness but produced by a definite mathematical procedure:

    ‘most computers have built-in functions which will generate sequences of pseudorandom numbers’
    ‘pseudorandom noise’
    • ‘Such sequences of pseudorandom numbers play crucial roles not only in computer games but also in simulations of physical processes.’
    • ‘In the clairvoyance condition, the computer had already selected the target using a pseudorandom number generator and had stored the choice directly onto disk by the time that participants made their guess.’
    • ‘The fitness of this ‘zygote’ is evaluated and pseudorandom numbers are used to determine whether to pass one of its ‘gametes’ to the next generation.’
    • ‘Cryptanalysts have analyzed many systems by breaking the pseudorandom number generators used to supply cryptographic keys.’
    • ‘Each bird was tested under the various lights in a pseudorandom sequence.’
