Title: Dynamic Restarting Schemes for Eigenvalue Problems

Technical Report ·
DOI:https://doi.org/10.2172/760299· OSTI ID:760299

In studies of restarted Davidson method, a dynamic thick-restart scheme was found to be excellent in improving the overall effectiveness of the eigen value method. This paper extends the study of the dynamic thick-restart scheme to the Lanczos method for symmetric eigen value problems and systematically explore a range of heuristics and strategies. We conduct a series of numerical tests to determine their relative strength and weakness on a class of electronic structure calculation problems.
