WebMar 6, 2000 · Then we provide a new, H k -competitive algorithm for paging. Our algorithm, as well as its analysis, is simpler than the known algorithm by McGeoch and Sleator. Another advantage of our algorithm is that it can be implemented with complexity bounds independent of the number of past requests: O (k 2 log k) memory and O (k 2) … WebCompetitive paging algorithms Michael Luby 1991, Journal of Algorithms The paging problem is that of deciding which pages to keep in a memory of k pages in order to minimize the number of page faults. We develop the …
