Efficiently implementable iterative methods for linear elliptic variational inequalities with constraints on the gradient of solution
The authors develop a new iterative method for finite-dimensional constrained saddle point problem with linear operator and prove the convergence of the method. The proposed method includes a generalized Uzawa method as a special case. The convergence proof of two-stage iterative methods are also given. Numerical examples demonstrate the high convergence rate of the methods and their efficiency.
