A Posteriori Suboptimal Error Estimates in Control Problems

Applied Mathematics and Computation, 1977
For the linear quadratic control problem, a lower bound for the performance index is established by simple methods. Using this bound, two important a posteriori error estimates are obtained, the first one measuring the deviation of the performance index, while the other is for the deviation of the state and control variables from the optimal solution ...

The Equivalence of A Posteriori Error Estimators

1995
For finite element discretzations of partial differential equations, various a posteriori error estimators have been proposed in the literature. They can be classified as follows: (1) estimators based on evaluating the residual of the discrete solution with respect to the strong form of the pde, (2) estimators based on the solution of auxiliary local ...

ON A POSTERIORI ERROR ESTIMATION FOR CONSTANT OBSTACLE PROBLEMS

2001
A posteriori error estimators for finite element approximations to variational inequalities are derived inthe model case of ``Poisson's inequality'' for a constant obstacle. These residual-type estimators yield global upper and, partially, local lower bounds for the true error.
