pseudorandom number

   Also found in: Wikipedia 0.01 sec.
(programming)pseudorandom number - One of a sequence of numbers generated by some algorithm so as to have an even distribution over some range of values and minimal correlation between successive values.

Pseudorandom numbers are used in simulation and encryption. They are pseudorandom not random because the sequence eventually repeats exactly and is entirely determined by the initial conditions.

One of the simplest algorithms is

x[i+1] = (a * x[i] + c) mod m

but this repeats after at most m numbers and successive numbers are closely related. Better algorithms generally use more previous numbers to calculate the next number.

This signal makes sense only to that base unit which has the same pseudorandom number generator as the cordless handset.
Fishman covers independent Monte Carlo, sample generation, pseudorandom number generation, variance reduction, Markov chain Monte Carlo, MCMC sample-path analysis, optimization by way of MCMC, and advanced concepts in MCMC, and includes a glossary and partial solutions to selected chapter exercises.
After that initial choice, the algorithm produces each new pseudorandom number by multiplying the preceding number by 17, dividing the result by 13, and taking the remainder.
