List Factoring and Relative Worst Order Analysisrved behavior of online algorithms for a range of different online problems. The contribution of this paper is twofold. First, it adds the static list accessing problem to the collection of online problems where relative worst order analysis gives better results. Second, and maybe more interesting,

Approximation Algorithms for Domination Searchdth and hypertree width. The task is to identify the minimum number of cops sufficient to catch the visible and fast robber. In .-domination search, the robber is being arrested if he resides inside a ball of radius . around some cop. In this setting, the power of the cops does not depend only on ho

A 3/2-Approximation Algorithm for Rate-Monotonic Multiprocessor Scheduling of Implicit-Deadline Taskarbitrary parameter . ∈ ℕ it yields solutions with at most . many processors, thus it gives an asymptotic 3/2-approximation algorithm. This improves over the previously best known ratio of 7/4. Our algorithm can be implemented to run in time .(..), where . is the number of tasks. It is based on cust

Online Tracking of the Dominance Relationship of Distributed Multi-dimensional Dataip of some distributed multi-dimensional data. Such data keep changing from time to time. The objective is to minimize the communication between the root and the distributed data sources. Assume that data are chosen from the .-dimensional grid {1, 2, ⋯ , .}., we give an .(. log.)-competitive algorit
