  • pseudorandom number — (programming)   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.

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.
