CSSE230 – Data Structures and Algorithms

Spring 2014–15 (aka 201530)

Schedule Overview

All non-Moodle web pages for the course are available from this index page.

This schedule page will begin with the schedule from a previous term, which will be updated as we go. We’ll try to update assignments and readings at least a week in advance. We’ll update daily schedules and slides just before class.

Preparation is to be completed before the class session.
