This course meets Mondays, Wednesdays, and Fridays, 2:00 - 2:50 in Steinhaus Hall 128. Coursework will consist of weekly homeworks, turned in at the start of lecture and returned at the reader's office hours, one midterm, and a comprehensive final exam. Group work on homeworks is permitted; each student should turn in his or her own copy of the homeworks. Homeworks will usually be assigned Fridays and due on the following Friday. Grading will be based 20% on homework, 35% for the midterm, and 45% for the final.

Instructor office hours are TBA. The reader for the course is Maral Amir; office hours TBA.

There is no
required textbook; however, much of the course material will be drawn
from the Wikipedia articles collected together in
the Wikipedia "book"
*Fundamental Data Structures*.
Additionally, suggested internet readings for the
topics covered here will be linked from the schedule of topics.

This course may be used as part of the comprehensive exam in the computer science masters program. To pass the comprehensive exam, students must score at least 66% of the possible points on the final examination for the course. Students who wish to take the comprehensive exam but are not enrolled in the course should contact me by email before the end of week 8 of the quarter to reserve a place in the exam.
