1990-05-01 In a recent paper, a bound was derived on the convergence of the multigrid V-cycle for the case when the solution is in the Sobolev space H^1^+^@a but not in H^1^+^@a^', @a' #62;; @a, showing that Example 6.5 Multigrid F-cycle. In between the V-cycle and the W-cycle is the F-cycle, see Figure 6.3. The F-cycle starts with the restriction to the coarsest grid.
The computational works of these multigrid cycles are given to show their numerical efficiency. Numerical results
Multigrid is a scalable method for solving linear equations. • Relaxation methods F. = f and A. C as the discrete form of the operator on the coarse grid, a simple coarse Alternatively, in a W-cycle, the coarser grids are solved m

Multigrid preconditioning is used in practice even for linear systems, typically with one cycle per iteration, e.g., in Hypre. Its main advantage versus a purely multigrid solver is particularly clear for nonlinear problems, e.g., eigenvalue problems.
