Algorithms and Lower Bounds for the Maximum Overlap of Two Polygons Under Translation
Mikkel Abrahamsen, Sujoy Bhore, Maike Buchin +4
A fundamental problem in shape matching and geometric similarity is computing the maximum area overlap between two polygons under translation. For general simple polygons, the best…

Bounding a Polygon by a Minimum Number of Vertices
Mikkel Abrahamsen, Jack Stade, Shuyi Yan +1
Suppose that a polygon is given as an array containing the vertices in counterclockwise order. We analyze how many vertices (including the index of each of these vertices) we n…

Computing Non-Obtuse Triangulations with Few Steiner Points
Mikkel Abrahamsen, Florestan Brunck, Jacobus Conradi +2
We present the winning implementation of the Seventh Computational Geometry Challenge (CG:SHOP 2025). The task in this challenge was to find non-obtuse triangulations for given pla…
