A Manhattan p–q path is a geodesic in the Manhattan (or L1-) metric that connects p and q, i.e. a staircase path between p and q. Given a set of points P in the plane, a Manhattan network is a set of axis-parallel line segments that contains a Manhattan p–q path for each pair {p, q} of points in P. In this paper we consider the minimum...

Graphical features on map, charts, diagrams and graph drawings usually must be annotated with text labels in order to convey their meaning. In this paper we focus on a problem that arises when labeling schematized maps, e.g. for subway networks. We present algorithms for labeling points on a line with axis-parallel rectangular labels of equal...
