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
  • Applications: Convex models in mathematical imaging

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
