    Course Overview

    We will study efficient algorithms for a variety of fundamental geometric problems: convex hulls, Voronoi diagrams/Delaunay triangulations, low-dimensional linear programming, line segment intersection, polygon triangulation, geometric shortest paths, visibility, etc. Computational geometry has applications to many areas (geometric data are everywhere), although the focus of the course is on theoretical results and techniques (we will encounter lots of cool algorithmic ideas, including divide-and-conquer, prune-and-search, randomization, plane sweep, etc.). A solid background in algorithm design and analysis is assumed (at the level of CS374).


    There is no required textbook, but you may find the following useful:
