Abstract

We consider the problem of placing arrow heads in directed graph drawings without them overlapping other drawn objects. This gives drawings where edge directions can be deduced unambiguously. We show hardness of the problem, present exact and heuristic algorithms, and report on a practical study.

Research on this problem started at the Dagstuhl seminar 15052 [2]. We thank Michael Kaufmann and Dorothea Wagner for valuable discussions, and the anonymous referees for their comments and suggestions.
