Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. It includes a basic overview of elementary iterative methods for large, sparse, linear systems of equations. A major computer project carried out in Matlab or Python is directed towards solving a large-scale applied problem, on the order of one hundred million unknowns.

The topics of the first edition have been enhanced with additional discussion, new numerical experiments, and improved figures. New topics in the second edition include nonlinear equations, Neumann boundary conditions, variable mesh and variable coefficient problems, anisotropic problems, algebraic multigrid AMG , adaptive methods, and finite elements.
This introductory book is ideally suited as a companion textbook for graduate numerical analysis courses. It is written for computational mathematicians, engineers, and other scientists interested in learning about multigrid. During those years, the field of multigrid and multilevel methods has expanded at a tremendous rate, reflecting progress in the development and analysis of algorithms and in the evolution of computing environments.
Because of these changes, the first edition of the book has become increasingly outdated and the need for a new edition has become quite apparent.
With the overwhelming growth in the subject, an area in which I have never done serious research, I felt remarkably unqualified to attempt a new edition. Realizing that I needed some help, I recruited two experts to assist with the project.
Steve McCormick Department of Applied Mathematics, University of Colorado at Boulder is one of the original researchers in the field of multigrid methods and the real instigator of the first edition. There could be no better collaborator on the subject.
Van Emden Henson Center for Applied Scientific Computing, Lawrence Livermore National Laboratory has specialized in applications of multigrid methods, with a particular emphasis on algebraic multigrid methods. Our collaboration on a previous SIAM monograph made him an obvious choice as a co-author. With the team in place, we began deliberating on the content of the new edition. It was agreed that the first edition should remain largely intact with little more than some necessary updating.
Our aim was to add a roughly equal amount of new material that reflects important core developments in the field. A topic that probably should have been in the first edition comprises Chapter 6: FAS Full Approximation Scheme , which is used for nonlinear problems.
Chapter 7 is a collection of methods for four special situations that arise frequently in solving boundary value problems: Neumann boundary conditions, anisotropic problems, variable-mesh problems, and variable-coefficient problems. One of the chief motivations for writing a second edition was the recent surge of interest in algebraic multigrid methods, which is the subject of Chapter 8.
Finally, in Chapter 10, we depart from the predominantly finite difference approach of the book and show how finite element formulations arise. This chapter provides a natural closing because it ties a knot in the thread of variational principles that runs through much of the book.
