Achi Brandt developed multilevel approaches to boundary-value problems. His adaptive multigrid work connects local relaxation, which reduces oscillatory error, with coarse-grid correction for slowly varying error. The combination explains why changing scale can be more effective than repeating one relaxation scheme.[ref]
