Comparison of the Local Defect Correction Iteration and the Fast AdaptiveComposite Grid Iteration

摘要

The local defect correction method by Hackbusch and the fast adaptive compositegrid method by McCormick are presented for a model situation. The main differences and similarities between both methods are discussed. It is shown that for suitable choices of the components the iterates in the local defect correction iteration and in the fast adaptive composite grid iteration are the same.
