متن کاملImproved Space Bounds for Strongly Competitive Randomized Paging Algorithms
Paging is a prominent problem in the field of online algorithms. While in the deterministic setting there exist simple and efficient strongly competitive algorithms, in the randomized setting a tradeoff between competitiveness and memory is still not settled. In this paper we address the conjecture in [2], that there exist strongly competitive randomized paging algorithms using o(k) bookmarks, ...
متن کاملCompetitive Paging Algorithms AMOS FIAT
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 marking algorithm, a randomized on-line algorithm for the paging problem. We prove that its expected cost on any sequence of requests is within a factor of 2Hk of optimum. (Where Hk is the kth harmonic number, which is roughly Ink.) The best such facto...
متن کاملCompetive Analysis of Randomized Paging Algorithms
The paging problem is deened as follows: we are given a two-level memory system, in which one level is a fast memory, called cache, capable of holding k items, and the second level is an unbounded but slow memory. At each given time step, a request to an item is issued. Given a request to an item p, a miss occurs if p is not present in the fast memory. In response to a miss, we need to choose a...
متن کاملCompetitive Analysis of Paging: A Survey
This paper is a survey of competitive analysis of paging. We present proofs showing tight bounds for the competitive ratio achievable by any deterministic or randomized online algorithm. We then go on to discuss variations and reenements of the competitive ratio and the insights they give into the paging problem. Finally, we variations to the online paging problem to which competitive analysis ...
