======Algorithms, Fall 2019======
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 six TA sessions on 9/24, 10/8,
10/29, 11/19, 12/10, and 12/31.)
