A new, area-based mesh simplification algorithm is described. The proposed algorithm removes the center vertex of a polygon which consists of n ≥ 3 faces and represents that po...

We consider the classical vertex cover and set cover problems with the addition of hard capacity constraints. This means that a set (vertex) can only cover a limited number of its...

We study the inapproximability of Vertex Cover and Independent Set on degree d graphs. We prove that: • Vertex Cover is Unique Games-hard to approximate to within a factor 2−(...
