A modern trend is toward solving complicated physical problems on large unstructured grids. Fast and efficient multigrid methods are attractive for many problems; however, the use of unstructured grids makes writing multigrid solvers tedious and difficult. Algebraic multigrid (AMG) uses only the basic information of the problem (but not geometry) to devise coarsening schemes and operators that give multigrid-like performance in a wide variety of settings. This minisymposium highlights the state-of-the-art in AMG research. Speakers from four of the most active AMG research centers describe new trends in AMG methodology, including parallel implementation, finite-element based AMG, and smoothed agglomeration methods.
