Abstract. Allowing read operations to return stale data with low probability has been proposed as a means to increase availability in quorums systems. Existing solutions that allow...
Abstract. We consider the problem of overcoming (Distributed) Denial of Service (DoS) attacks by realistic adversaries that can eavesdrop on messages, or parts thereof, but with so...
We study greedy routing over n nodes placed in a ring, with the distance between two nodes defined to be the clockwise or the absolute distance between them along the ring. Such ...
We analyze the problem of efficient distributed storage of information in a message-passing environment where both less than one third of the servers, as well as an arbitrary num...
An instance of the multi-radius cover problem consists of a graph G = (V, E) with edge lengths l : E → R+ . Each vertex u ∈ V represents a transmission station for which a tra...
We present efficient approximation algorithms for a number of problems that call for computing the prices that maximize the revenue of the seller on a set of items. Algorithms for ...
Important generalizations of the Vertex Cover problem (Connected Vertex Cover, Capacitated Vertex Cover, and Maximum Partial Vertex Cover) have been intensively studied in terms of...
Abstract. Settling a ten years open question, we show that the NPcomplete Feedback Vertex Set problem is deterministically solvable in O(ck ·m) time, where m denotes the number of...
