Regularization-robust preconditioners for time-dependent PDE constrained optimization problems

Regularization-robust preconditioners for time-dependent PDE constrained optimization problems

Mostra altre versioni (1)

In this article, we motivate, derive and test effective preconditioners to be used with the Minres algorithm for solving a number of saddle point systems, which arise in PDE constrained optimization problems. We consider the distributed control problem involving the heat equation with two different...
