    On the Number of Edges of Fan-Crossing Free Graphs

    A graph drawn in the plane with n vertices is fan-crossing free if there is no triple of edges e,f and g, such that e and f have a common endpoint and g crosses both e and f. We prove a tight bound of 4n − 9 on t...

    Computing k-center over Streaming Data for Small k

    The Euclidean k-center problem is to compute k congruent balls covering a given set of points in ℝ d such that the radius is minimized. We consider the k-center problem in ℝ ...

    The Cost of Bounded Curvature

    We study the motion-planning problem for a car-like robot whose turning radius is bounded from below by one and which is allowed to move in the forward direction only (Dubins car). For two robot configurations σ,...

    Measuring the Similarity of Geometric Graphs

    What does it mean for two geometric graphs to be similar? We propose a distance for geometric graphs that we show to be a metric, and that can be computed by solving an integer linear program. We also present ...

    Throwing Stones Inside Simple Polygons

    Given two sets A and B of m non-intersecting line segments in the plane, we show how to compute in O(m logm) time a data structure that uses O(m) space and allows to answer the following query in O(logm) time: Gi...
