Abstract EN
We propose an augmented Arnoldi-Tikhonov regularization method for the solution of large-scale linear ill-posed systems.
This method augments the Krylov subspace by a user-supplied low-dimensional subspace, which contains a rough approximation of the desired solution.
The augmentation is implemented by a modified Arnoldi process.
Some useful results are also presented.
Numerical experiments illustrate that the augmented method outperforms the corresponding method without augmentation on some real-world examples.
