Course Overview

This course is about data structures in computational geometry. We will discuss fundamental techniques and recent theoretical developments for a variety of basic geometric data structuring problems in a variety of models. Possible topics include:

Prerequisite: a solid background in algorithm design and analysis (e.g., at the level of CS 374) is assumed.

Course Work

(Assignments and projects may be done individually or in groups of 2.)
