Topic outline

  • Computational Geometry 2023 Spring


    Computational geometry considers problems with geometric input, and its goal is to design efficient algorithms and to study the computational complexity of such problems. A typical input to a problem is some set of points or segments in the Euclidean plane (or higher dimensional Euclidean space). Examples of problems include computing the convex hull of a point set, finding clusters, or setting up a data structure to find the nearest point to a given query point. Although not the main focus of this course, there is a very rich application domain, including computer graphics, computer-aided design and manufacturing, machine learning, robotics, geographic information systems, computer vision, integrated circuit design, and many other fields.
