In this course, we will study the solution of computational problems from two complementary perspectives: (i) The Algorithm Design & Analysis perspective, i.e., the design methods one can employ in order to build efficient algorithms for fundamental problems (e.g., network flows), and the analysis of their running times. We will study the design of Divide-and-Conquer, Greedy and Dynamic Programming algorithms, approximations algorithms that are efficient but can only provide approximation-of-the-optimal guarantees, and the use of randomization in our algorithms. (ii) The Computational Complexity perspective, i.e., the study of the inherent difficulty of solving a problem computationally. As opposed to the 'easyness' of solving a problem, demonstrated by efficient algorithms designed in (i), in this part we will study how one can show that a problem is at least as 'hard' to solve as another problem, using reductions, and will classify our problems into complexity classes such as P, NP, PSPACE, according to their 'hardness'.
More specifically, students should know and understand:

Student Assessment (Grading)
Policy on collaboration for homework assignments: Collaboration on the homework assignments is highly encouraged, within reasonable limits. Students are expected to discuss assignment problems with each other, and to cooperate on solutions in groups of no more than 5 people. However, the final write-up should be done by individual students (i.e. individual students should be able to explain their solutions by themselves, if such an explanation is asked for by the instructor) and the names of the collaborators should appear on the paper. Cooperation and teamwork are necessary for the success of any complex task (the design of algorithms being one such task), and it is the instructor's hope that students will come to appreciate them in a constructive way. Please see the instructor if you need someone to collaborate with.
Policy on delayed assignments: Assignments delivered between the lecture they were due and the following lecture get 50% of total credit. After the following lecture, no credit given.
collaboration during exams: ABSOLUTELY
NO COLLABORATION DURING EXAMS!!!

dishonesty consists of misrepresentation by deception or by
fraudulent means and can result in serious consequences, e.g. the grade of
zero on an assignment, loss of credit with a notation on the transcript
(notation reads: "Grade of F assigned for academic dishonesty"), and/or
suspension or expulsion from the university.
It is your responsibility to understand what constitutes academic
dishonesty. For information on the various kinds of academic dishonesty
please refer to the Academic Integrity Policy, specifically Appendix 3,
located at http://www.mcmaster.ca/senate/academic/ac_integrity.htm
The following illustrates only three forms of academic dishonesty:
1. Plagiarism, e.g. the submission of work that is not one's own or for which other credit has been obtained. (e.g. submitting a copy of someone else's writeup for an assignment)
2. Improper collaboration in group work. (e.g. collaboration between groups in an assignment)
3. Copying or using unauthorized aids in tests and examinations."
"The Faculty of Engineering is
concerned with ensuring an environment that is free of all
discrimination. If there is a problem, individuals are
reminded that they should contact the Department Chair, the
Sexual Harrassment Officer or the Human Rights Consultant, as
the problem occurs."
"The instructor and university
reserve the right to modify elements of the course during
the term. The university may change the dates and deadlines
for any or all courses in extreme circumstances. If either
type of modification becomes necessary, reasonable notice
and communication with the students will be given with
explanation and the opportunity to comment on changes. It is
the responsibility of the student to check their McMaster
email and course websites weekly during the term and to note
All assignments are
