An adaptive finite element method for distributed elliptic optimal control problems with variable energy regularization

Ulrich Langer, Richard Löscher, Olaf Steinbach +1

We analyze the finite element discretization of distributed elliptic optimal control problems with variable energy regularization, where the usual $L^{2} (Ω)$ norm regularization term…

Robust finite element discretization and solvers for distributed elliptic optimal control problems

Ulrich Langer, Richard Löscher, Olaf Steinbach +1

We consider standard tracking-type, distributed elliptic optimal control problems with $L^{2}$ regularization, and their finite element discretization. We are investigating the $L^{2}$ …

Space-time finite element discretization of parabolic optimal control problems with energy regularization

Ulrich Langer, Olaf Steinbach, Fredi Tröltzsch +1

We analyze space-time finite element methods for the numerical solution of distributed parabolic optimal control problems with energy regularization in the Bochner space $L^2(0,T;H…
