Distance-Ranked Connectivity Compression of Triangle Meshes
We present a new, single-rate method for compressing the connectivity information of a connected 2-manifold triangle mesh with or without boundary. Traditional compression schemes...

On the k-additive Core of Capacities
We investigate in this paper the set of kadditive capacities dominating a given capacity, which we call the k-additive core. We study its structure through achievable families, wh...

A Primal-Dual Approximation Algorithm for Partial Vertex Cover: Making Educated Guesses
We study the partial vertex cover problem. Given a graph G = (V, E), a weight function w : V → R+ , and an integer s, our goal is to cover all but s edges, by picking a set of v...

An exact algorithm for the capacitated vertex p-center problem
We develop a simple and practical exact algorithm for the problem of locating p facilities and assigning clients7 to them within capacity restrictions in order to minimize the max...
