The general two-server problem
We consider the general on-line two-server problem in which at each step both servers receive a request, which is a point in a metric space. One of the servers has to be moved to its request. The special case where the requests are points on the real line is known as the CNN-problem. It has been a famous open question in on-line optimization if an algorithm with a constant competitive ratio exi...
متن کاملTwo-Server Network Disconnection Problem
Consider a set of users and servers connected by a network. Each server provides a unique service which is of certain benefit to each user. Now comes an attacker, who wishes to destroy a set of edges of the network in the fashion that maximizes his net gain, namely, the total disconnected benefit of users minus the total edge-destruction cost. We first discuss that the problem is polynomially s...
متن کاملThe Generalized Work Function Algorithm Is Competitive for the Generalized 2-Server Problem
The generalized 2-server problem is an online optimization problem where a sequence of requests has to be served at minimal cost. Requests arrive one by one and need to be served instantly by at least one of two servers. We consider the general model where the cost function of the two servers may be different. Formally, each server moves in its own metric space and a request consists of one poi...
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 ...
