Detailed Description

Convergence criterion which looks at the weighted absolute value of the residual.

For the WeightedResidualReductionCriterion, the error of the solution is defined as

$e^k = \max_i\{ \left| w_i r^k_i \right| \}\;,$

where $r^k = \mathbf{A} x^k - b$ is the residual for the k-th iterative solution vector $x^k$ and $w_i$ is the weight of the $i$ -th linear equation.

In addition, to the reduction of the maximum defect, the linear solver is also considered to be converged, if the defect goes below a given absolute limit.
