On-Line Versions of Handouts from Class:

Course Information (AMS 345), Fall 2015 (available soon!)
Assignments, handouts, practice exams, and solutions to assignments will be available via Blackboard.
The introductory class on Tuesday, August 25 will give an overview of what computational geometry is and what types of problems we study in the course. I will include some demos, which are applets linked from the slides (available on Blackboard).
