A DC-Reformulation for Gradient- $L^{0}$ -Constrained Problems

Bastian Dittrich, Evelyn Herberg, Roland Herzog +1

Cardinality constraints in optimization are commonly of $L^{0}$ -type, and they lead to sparsely supported optimizers. An efficient way of dealing with these constraints algorithmical…

Solving Semi-Linear Elliptic Optimal Control Problems with $L^{1}$ -Cost via Regularization and RAS-Preconditioned Newton Methods

Gabriele Ciaramella, Michael Kartmann, Georg Müller

We present a new parallel computational framework for the efficient solution of a class of $L^{2}$ / $L^{1}$ -regularized optimal control problems governed by semi-linear elliptic partial…

Nonlinear optimized Schwarz preconditioner for elliptic optimal control problems

Gabriele Ciaramella, Felix Kwok, Georg Müller

We introduce a domain decomposition-based nonlinear preconditioned iteration for solving nonlinear, nonsmooth elliptic optimal control problems, with a nonlinear reaction term, $L^…
