A Robust Approximation of the Schur Complement Preconditioner for an Efficient Numerical Solution of the Elliptic Optimal Control Problems

In this paper, we consider the numerical solution of the optimal control problems of<br />the elliptic partial differential equation. Numerically tackling these problems using the finite<br />element method produces a large block coupled algebraic system of equations of saddle point<b...
