Linear algebra and basic knowledge of numerical methods, or intention of conducting projects related to scientific computation.Content
We study the formulations and algorithms solving convex optimization problems. The topics include convex sets, functions, optimality conditions, duality concepts. If time permits, we will talk about gradient descent, conjugate gradient, interior-point methods, and applications. The objective of the course is to provide students the background and techniques for scientific computing and system optimization.Lectures
