Geometric speed-up techniques for finding shortest paths in large sparse graphs (2003)

Dorothea Wagner, Thomas Willhalm, D. Wagner, T. Willhalm

In this paper, we consider Dijkstra’s algorithm for the single source single target shortest paths problem in large sparse graphs. The goal is to reduce the response time for online queries by...

Visualization of bibliographic networks with a reshaped landscape metaphor (2002)

Ulrik Brandes, Thomas Willhalm, Fachbereich Informatik Und Informationswissenschaft, U. Br, T. Willhalm

We describe a novel approach to visualize bibliographic networks that facilitates the simultaneous identification of clusters (e.g., topic areas) and prominent entities (e.g., surveys or landmark...
