Seminar

German title
Nichtglatte Optimierung

Contents
The seminar covers optimization problems which do not satisfy the typical differentiability requirements. Starting from convex functions, the notion of subdifferentials is introduced and with it optimality conditions for unrestricted problems are derived. Allowing infinity as a function value, restrictions can be included with the help of the indicator function. Based on these regularization procedures and subgradient methods for the numerical solution of non-smooth optimization problems are discussed. Also a generalized (non-smooth) Newton method is introduced.
