The $h$-robust convergence of the local multigrid V-cycle has been thoroughly discussed in previous presentations. Now we present the proof of its optimal computational complexity and the performance of nested iterations (full multigrid). We will discuss different stopping criteria and illustrate their usefulness for a variety of numerical examples.
