|TA||Shuonan Dong, Vincent Antaki, Zilun Peng, Jaspal Singh, Hossein Aboutalebi, Scott Fujimoto. TA's are only responsible for grading, and you should only contact them regarding the grading of your assignments and exams.|
|Corequisite||MATH 235 or MATH 240 or MATH 363. (This course relies on the material from MATH 240 or MATH 353).|
|Lecture||Tuesday-Thursday 8:35-9:55 AM, Leacock Building 26. The lectures will be Video Recorded.|
|Office hours||Tuesday 2:00-3:00 pm in McConnell 308. If you want to meet outside office hours, the best thing is to send me an email, but you can also just drop by my office, and if I'm not busy I will answer your questions. There is also a facebook group "COMP 251 Fall 2017" where you can post questions, and have discussions.|
|Textbook||Jon Kleinberg and Eva Tardos, Algorithm Design, 2006. Official slides for the book can be found here|
This course is an undergraduate course on the design of algorithms and data structures. Topics include Basics of Algorithms Analysis, Greedy Algorithms, Divide and Conquer technique, Dynamic Programming, and Network Flows.
This is a rigorous course with an emphasis on mathematical proofs rather than implementations. Hence it is important that you are already familiar with the material covered in Math 240, Math 235, or Math 363.
Homework (20% = 5 x 4%). The homework will be graded based on correctness rather than effort alone. Each assignment will be posted on the course web page. The homework must be submitted through mycourses. Your grades will be posted on mycourses.
Late homeworks can be submitted until 48 hours after the deadline. There will be a penalty of -25% for one-day delays, and -40% for two-day delays on late homeworks.
Final grade is whichever of (Homework 20% + Midterm 30% + final 50%) or (Homework 20% + Midterm 15% + final 65%) that results in a better grade. There will be two exams: a midterm in October and a final exam in December. The exams are closed-book, and closed-notes.
