CO 769 Syllabus (Winter 2023)
Convex Relaxations of Numerically Hard Problems; Efficient Numerical Solutions

There will be four assignments with the last due on Fri. Apr. 14.
50% for the final take-home assignment/exam; and 50% for 3 assignments during the semester.
The course will be self-contained. The required theory will generally be covered when it arises. We will cover (time permitting) elements from the following:
