: A large variety of emerging Computational Grid applications require versioning services to support effective management of constantly changing datasets and implementations of dat...
d Abstract) Bertrand Ducourthial Sofiane Khalfallah Franck Petit We propose a group membership service for asynchronous wireless dynamic ad hoc networks. It maintains as long as p...
A spanning subgraph H of a graph G is a 2-detour subgraph of G if for each x, y V (G), dH (x, y) dG(x, y) + 2. We prove a conjecture of Erdos, Hamburger, Pippert, and Weakley by ...
We give the first representation-independent hardness results for PAC learning intersections of halfspaces, a central concept class in computational learning theory. Our hardness ...
We prove that for every c > 0 there exists a constant K = K(c) such that every graph G with n vertices and minimum degree at least cn contains a cycle of length t for every even...
