WitrynaIt is proved that thick restarted, nonpreconditioned Davidson is equivalent to the implicitly restarted Arnoldi and motivates the development of a dynamic thick restarting scheme for the symmetric case, which can be used in both Davidson and implicit restarting Arnoldi. The Davidson method is a popular preconditioned variant of the Arnoldi … Witryna1 sty 1995 · Implicit restarting is a technique for combining the implicitly shifted QR mechanism with a k-step Arnoldi or Lanczos factorization to obtain a truncated form …
