Directed Animals and Gas Models Revisited
In this paper, we revisit the enumeration of directed animals using gas models. We show that there exists a natural construction of random directed animals on any directed graph t...

Directed tree-width examples
In [1] Johnson, Robertson, Seymour and Thomas define the notion of directed tree-width dtw(D) of a directed graph D. They ask whether dtw(D) ≥ k − 1 implies that D has a have...

A simple transitive signature scheme for directed trees
Transitive signatures allow a signer to authenticate edges in a graph in such a way that anyone, given the public key and two signatures on adjacent edges (i, j) and (j, k), can c...

Integrating Edge Routing into Force-Directed Layout
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...

Incremental Layout in DynaDAG
Abstract. Generating incrementally stable layouts is important for visualizing dynamic graphs in many applications. This paper describes DynaDAG, a new heuristic for incremental la...
