The Weighted 2-Server Problem
We consider a generalization of the 2-server problem in which servers have diierent costs. We prove that, in uniform spaces, a version of the Work Function Algorithm is 5-competitive, and that no better ratio is possible. We also give a 5-competitive randomized, memoryless algorithm for uniform spaces, and a matching lower bound. For arbitrary metric spaces, in contrast with the non-weighted ca...
متن کاملCompetitive Algorithms for the Weighted Server Problem
Fiat, A. and M. Ricklin, Competitive algorithms for the weighted server problem, Theoretical Computer Science 130 (1994) 85-99. In this paper we deal with a generalization of the k-server problem (Manasse et al. 1988) in which the servers are unequal. In the weighted server mode1 each of the servers is assigned a positive weight. The cost associated with moving a server equals the product of th...
متن کاملthe problem of divine hiddenness
این رساله به مساله احتجاب الهی و مشکلات برهان مبتنی بر این مساله میپردازد. مساله احتجاب الهی مساله ای به قدمت ادیان است که به طور خاصی در مورد ادیان ابراهیمی اهمیت پیدا میکند. در ادیان ابراهیمی با توجه به تعالی خداوند و در عین حال خالقیت و حضور او و سخن گفتن و ارتباط شهودی او با بعضی از انسانهای ساکن زمین مساله ای پدید میاید با پرسشهایی از قبیل اینکه چرا ارتباط مستقیم ویا حداقل ارتباط وافی به ب...
15 صفحه اولThe Infinite Server Problem
We study a variant of the k-server problem, the infinite server problem, in which infinitely many servers reside initially at a particular point of the metric space and serve a sequence of requests. In the framework of competitive analysis, we show a surprisingly tight connection between this problem and the (h, k)-server problem, in which an online algorithm with k servers competes against an ...
متن کاملThe k-server problem
The k-server problem is perhaps the most influential online problem: natural, crisp, with a surprising technical depth that manifests the richness of competitive analysis. The k-server conjecture, which was posed more that two decades ago when the problem was first studied within the competitive analysis framework, is still open and has been a major driving force for the development of the area...
