The lecture gives an introduction into the field of convex optimization and details the most important numerical methods for the solution of convex optimization problems.
- Preliminaries: Convex sets, convex functions, convex optimization problems (LPs, QPs, SOCPs, SDPs)
- Theory: Separation theorems, duality, subdifferential calculus, existence and optimality
- Algorithms: Gradient-based methods for smooth optimization, proximal-point and splitting methods for non-smooth optimization
- Applications: Convex models in mathematical imaging and data science

You are supposed to solve at least 50% of the numerical exercises (Matlab, Pyhton) in order to participate in the exam. There will be no points, only “OK”, “Not OK” or “ ” if nothing was handed in
Software Practical: Convex Optimization
The software practical is suited for students attending the lecture on Convex Optimization that additionally wish to apply the algorithms and concepts to concrete examples in order to get a deeper understanding.
Registration: in the lecture, or mail to Stefania Petra.
