Large-scale nonlinear optimization problems require special numerical routines for efficient solution. Usually, methods like Sequential Quadratic Programming are used to solve the nonlinear optimization problem. However, at each iteration a large-scale quadratic optimization problem occurs. Its solution is obtained by an iterative solver like CG or GMRES. The efficiency of these methods and hence of the overall method is heavily dependent on the use of proper preconditioners. The speakers will present several methods and an important application to the numerical solution in groundwater modeling.
