COMP 530: Schedule

This schedule is also available as an ical file that you can subscribe to.

All material covered in the lectures, labs, and required readings may appear on the exams.

Optional readings provide additional explanation of material covered in class that can be useful in preparing for the exams.

Initially, I will post slides, notes, or videos from the last incarnation of this course (if they exist), and incrementally replace them with the versions presented in class (perhaps with fixes after class) as the semester progresses.

Papers are only accessible to hosts in the unc.edu domain, although most are available elsewhere online.

New lecture videos will be posted in Panopto/Sakai.

The schedule of topics is tentative, and may adjust over the course of the semester.
