======Algorithms, Spring 2017======
The goal of this course is to acquaint the students with basic computer
algorithms and their design principles and to cultivate the students' ability
in designing and analyzing algorithms independently.

=====Syllabus/Schedule (with links to notes/slides)=====
This course provides an introduction to the design and analysis of computer
algorithms. A particular emphasis is given to **principles of mathematical
induction** and their use in designing algorithms. The course will cover most
of Manber's book plus supplementary material, including a few chapters of the
book by Cormen //et al.// (Note: a TA session will precede a class meeting
whose date is marked with an *. There are four TA sessions on 3/21, 4/11,
5/9, and 6/6.)
