A coin tossing algorithm for counting large numbers of events. (English) Zbl 0764.68077
Summary: R. Morris [Commun. ACM 21, 840-842 (1978; Zbl 0386.68035)] has proposed a probabilistic algorithm to count up to \(n\) using only about \(\log_ 2\log_ 2n\) bits. A slightly more general concept is introduced that allows to obtain a smoother average case behaviour. This concept is general enough to cover the analysis of an algorithm where the randomness is simulated by coin tossings.
