Numerical solution of elliptic distributed optimal control problems with boundary value tracking
Ulrich Langer, Richard Löscher, Olaf Steinbach +1
We consider some boundary value tracking optimal control problem constrained by a Neumann boundary value problem for some elliptic partial differential equation where the control a…
State-based approach to the numerical solution of Dirichlet boundary optimal control problems for the Laplace equation
Ulrich Langer, Richard Löscher, Olaf Steinbach +1
We investigate the Dirichlet boundary control of the Laplace equation, considering the control in , which is the natural space for Dirichlet data when the sta…
State-based nested iteration solution of optimal control problems with PDE constraints
Ulrich Langer, Richard Löscher, Olaf Steinbach +1
We consider an abstract framework for the numerical solution of optimal control problems (OCPs) subject to partial differential equations (PDEs). Examples include not only the dist…
A Posteriori Single- and Multi-Goal Error Control and Adaptivity for Partial Differential Equations
Bernhard Endtmayer, Ulrich Langer, Thomas Richter +2
This work reviews goal-oriented a posteriori error control, adaptivity and solver control for finite element approximations to boundary and initial-boundary value problems for stat…
