Course content

Course goals:  Data structures are ways of organising the data involved in computation, suitable for representation in and manipulation by computers.  Algorithms are precisely stated, general problem solving methods.  Data structures and algorithms are central to computer science.  They are also integrally related: neither can be studied fruitfully without knowledge of the other.

This course has two goals: First, to survey several important data structures and algorithms; and second, to introduce the basic tools and techniques for the analysis of algorithms and data structures.

Required Text: Cormen, Leiserson, Rivest, and Stein, Introduction to Algorithms , (2nd edition).

Course policies

Course evaluation:   There will be four homeworks, a midterm exam and a final exam. The relative weights of these components towards the final mark are shown in the table below:

Homework40% (10% each)

Important note: A mark of at least 35% on the final exam is required to pass the course.  Repeated differently:  If you receive less than 35% on the final exam, you automatically fail the course, regardless of how well you have done on homeworks or the midterm exam.

Prerequisites:   CSC207H1, CSC236H1/CSC238H1/CSC240H1; STA247H1/STA255H1/STA257H1

Homework marking:  For each homework assignment, solutions will be made available.

Late homework policy:  No late homeworks will be accepted. If you miss a homework deadline because of a medical or personal emergency, you must fill out the Special Consideration Form. (In case of a medical emergency, you must also submit the U of T Student Medical Certificate, completed and signed by your physician.)  If we judge your reason for missing the deadline to be valid, we will use the average mark you achieved in other homeworks as your mark for the missed homework.

Collaboration policy:   Students often learn a lot from working with one another. You are encouraged to meet with other students from class for this purpose. For example, you might work through exercises in the course text together or discuss any material you found confusing in lecture or in the text.

It is a good idea to get contact information (email address and telephone number) of at least two other students in the class. That way, if they miss a lecture, you can tell them important information and give them a copy of your lecture notes. They can return the favour if you miss a lecture.

In terms of assignment problems, you may work with zero, or one or two other students who are currently taking the class. If you choose to work in a group (of up to 3 student in total), please submit only one copy of your assignment, with all of your names and student numbers on each page. Assignments must be written up using only the text and your own notes as aids. The point is that your written report should be your own work. Do not let other students outside your group even look at your completed assignment solutions, since this can lead to copying. These rules are meant to ensure that all students understand their solutions to the problems well enough to write up solutions by themselves. Failure to comply with these guidelines is a serious academic offense.

You may not consult any material except the course textbook and your course notes. Note that finding (or copying) the solution to a homework problem on the web does not demonstrate your understanding of course material and, hence, will receive no credit.

Remarking policy:   If your request concerns a simple addition error, see the instructor.  To make any other kind of remarking request, you must fill this form , attach it to your homework assignment or test, and give it to the instructor of the course no later than one week from the date the marked assignment or test was made available to the class.  Remarking requests made after this deadline will not be accepted.

Missed midterm test policy:    If you miss the midterm test due to a medical or other serious emergency, get in touch with your instructor immediately, and fill out the Special Consideration Form. (In case of a medical emergency, you must also submit the U of T Student Medical Certificate, completed and signed by your physician.)  There will be no make-up test, but if we consider your reason for missing the test to be valid, we will use your final examination mark to compute your mark for the missed midterm test.

Attendance in tutorials:  Attendance in tutorials is as mandatory as attendance in lectures.   Formal records of attendance will not be taken. However, there will be material that is presented only in tutorial and not discussed in the lectures for which you are responsible and in which you may be tested in homeworks or exams.

Accessibility:   The University of Toronto is committed to accessibility. If you require accomodations or have any accessibility concerns, please visit as soon as possible or talk to one of the course professors.

    Posted on Sept 18: Accessibility services requires dependable volunteer note-takers to assist students with disabilities in accessing lecture information for this course. Volunteers report that by giving to the U of T community their class attendance and note taking skills improve. Volunteers need to: (1) Register at or come in person to 215 Huron St. Suite 939; (2) Upload their notes weekly or scan hand written notes. Email at or call 416 978 6186 if you have questions or are interested in volunteering. Thanks!
    Posted on Sept 19: Homework 1 has been updated. (I wrote question 3 in full so that you don't have to look it up in the textbook.)
    Posted on Sept 23: Extra office hours for HW1 this Thursday 4-5pm, and this Friday 1-2pm in Pratt Room 266.
    Posted on Sept 26: IMPORTANT: The tutorial room has changed. From now on it will be in the same room as the lecture, LM 161.
    Posted on Sept 27: Question 2 on HW1 is harder than I anticipated. As a result, you will have an extension for that question. All other problems are still due on Oct 1; question 2 will be due at the same time as HW2 (Oct 22).
    Posted on Sept 30: Homework 2 has been posted below.
    Posted on Oct 14: Extra office hours this week, Thursday 3-4pm and Friday 3-4pm in SF3207. Also solutions to HW1 have been posted below.
    Posted on Oct 21: I am still looking for someone to volunteer to share their class notes with a student registered with disability services. Please see my post above from Sept 18 and *please* consider volunteering. It will not take much of your time, and will be greatly appreciated. Thanks.
    Posted on Oct 24: My office hours this week will be on Monday, Oct 28, from 12-1 (the day before the test). Office hour on Thursday (Oct 31) will be cancelled.
