What this Course is About

It is easier to describe the course in terms of its mechanics. We will practise the precise statement of various computational problems, think about different strategies or algorithms to solve them, reason about their correctness, evaluate these algorithms from the point of view of efficiency (usually running time), and develop a feel for the difficulty of problems and the applicability of various techniques we will learn. It is convenient to organize the course in terms of the following topics:

We will cover two other topics, possibly from the following list: exact algorithms for hard problems, approximation algorithms, more of probabilistic algorithms, basic computational geometry algorithms, introduction to linear programming.


Algorithm Design, by Kleinberg and Tardos.


We will assume effectively an exposure to an undergraduate data structures course, so that when we talk about algorithms, you are comfortable at seeing how they might translate into programs. This also means you have seen the mechanics of analyzing the running time of simple algorithms. It helps to have also been exposed to an undergraduate algorithms course, in particular, to topics such as graph exploration (breadth first search, depth first search), and shortest path algorithms. Beyond this, we won't assume familiarity with specific topics, but rather hope for a certain maturity.


The grading will be based on about seven homeworks (40 percent), a midterm (25 percent), and a final (35 percent). One or two of the homeworks will be based on programming.

The policy on late homeworks is that you have a quota of three days for the entire semester that you may use for late submissions. So for example, there will be no penalty if you submit the third homework a day late, the fifth two days late, and the rest of the homeworks on time. Once you use up your quota of three days, any homework submitted late will not be accepted and you will get 0 points for that homework.

When you submit a homework X days late, your quota gets decreased by X irrevocably. You can only be late by an integer number of days -- if you submit 10 hours after the deadline, for example, your quota is depleted by one day.

Exam Dates

The midterm will be in class during class hours on Thursday, March 14. The final will be during finals week, as scheduled by the registrar's office. It will be held on Wednesday, May 15th, at 112 MH (Macbride), from 7.30 to 9.30 am.

What We Covered Each Week

We will keep track of what we covered each week here.

Handouts and Homeworks

We can expect this course to be reasonably similar to the spring 2012 offering.
