We study the integral uniform (multicommodity) flow problem in a graph G and construct a fractional solution whose properties are invariant under the action of a group of automorp...
We prove an exponential lower bound for the length of any resolution proof for the same set of clauses as the one used by Urquhart [13]. Our contribution is a significant simpli...
We present an algorithm for finding the minimum cut of an undirected edge-weighted graph. It is simple in every respect. It has a short and compact description, is easy to implemen...
Programslices have potentialuses in manysoftware engineering applications. Traditional slicing algorithms, however, do not work correctly on programs that contain explicit jump st...
Abstract. The typical use of force-directed layout is to create organiclooking, straight-edge drawings of large graphs while combinatorial techniques are generally preferred for hi...
