This page has the content from the course Introduction to Optimization Theory (MS&E213 / CS 269O) which I taught in Spring 2017. Here you can find the syllabus, lecture notes, and more. The Piazza page for class discussion is no longer active, but if you have questions about the content, please feel free to email me directly. I hope you enjoy the content as much as I enjoyed teaching the class.
This class will introduce the theoretical foundations of continuous optimization. Starting from first principles we show how to design and analyze simple iterative methods for efficiently solving broad classes of optimization problems. The focus of the course will be on achieving provable convergence rates for solving numerous complex large-scale problems. For more information about the course see the syllabus.
