Course Description

This is an introductory course on computational geometry and its applications. The primary focus is on algorithms and data structures for processing multi-dimensional and geometric data. The main topics covered in the course include the following: Multi-dimensional Range Searching, Convex Hulls, Intersection Detection, Polygon Triangulation, Point Location, Proximity and Voronoi Diagram, Delaunay Triangulation, Arrangements, Sampling and Epsilon Nets, and Lower Bounds.

This is a graduate level course, and students are expected to know the basic concepts of algorithm analysis (asymptotic notation, worst-case analysis) and data structures (linked lists, trees, priority queues).

Grading and Workload

Students can expect 3-4 written homework assignments, a midterm and a final exam. They will also be expected to read additional advanced material, not covered in lectures, from research papers.

Textbook and Lecture Notes

The textbook for the course is Computational Geometry, by de Berg, van Kreveld, Overmars, and Schwarzkopf. This is a fairly well-written introductory textbook. In addition, my own lecture slides will be available below. However, keep in mind that these slides are not an excuse to skip lectures. The lectures typically involve worked examples and interaction in the form of questions and answers, which can't be captured in the slides.

Homework Assignments

1. Homework #1. Due Oct 19.
2. Homework #2. Due Nov 4.
2. Homework #3. Due Nov 30.
