Multigrid Iterationstes the one-dimensional model problem. The proof demonstrates the complementary roles of the smoothing part and the coarse-grid correction. Moreover, the dependence of the convergence rate on the number of smoothing steps is determined. The multigrid iteration is defined in Section 11.4. Its computa
