Stochastic Galerkin Method and Hierarchical Preconditioning for PDE-constrained Optimization

Zhendong Li, Akwum Onwunta, Bedřich Sousedík

We develop efficient hierarchical preconditioners for optimal control problems governed by partial differential equations with uncertain coefficients. Adopting a discretize-then-op…
