Ginsburg and Karpiuk in 1995 introduced an algorithm that simulates human performance in tasks of generating random digits. We have compared sequences produced by this algorithm with human performance and truly random sequences. It is shown that the algorithm can be used to simulate human performance according to the measures on which it had been constructed. However, other peculiarities of human performance are not captured by the algorithm. The results are discussed with regard to current theories of human random-digit generation.
