A New Approximation of the Schur Complement in Preconditioners for PDE Constrained Optimization
Saddle point systems arise widely in optimization problems with constraints. The utility of Schur complement approximation is now broadly appreciated in the context of solving such saddle point systems by iteration. In this short manuscript, we present a new Schur complement approximation for PDE co...
