WebSuccessive Over Relaxation (SOR) • Again tabulating the values for d = 1,2 and 3 find d W SOR 1 O(N2) 2 O(N3/2) 3 O(N4/3) • Thus note that optimal SOR is not unreasonable for “moderately-sized” d = 3 problems. • Key issue: How to choose ω = ω OPT in order to get optimal performance • Except for cases where ρ GS ≡ ρ(G GS) is ... Web1. Introduction. The successive overrelaxation (SOR) method and its line variants [1,2,3] are among the most popular and efficient iterative methods used for solving large and sparse linear systems.Large linear systems appears in many areas of science and engineering, especially from the discretization of elliptic partial differential equations equation (3).
