%X Rational filter functions can be used to improve the convergence of the so-called contour-based eigensolvers, a popular family of algorithms for the solution of the interior eigenvalue problem. This talk provide an overview on how such filters can be optimized for performance and convergence based on a non-convex weighted Least-Square scheme.The net result is an almost parameter-free minimization framework with an enhanced usability and productivity which leads to rational functions outperforming state-of-art filters.
