Practical issues -- BackmatterThis book deals with algorithms for the solution of linear systems of algebraic equations with large-scale sparse matrices, with a focus on problems that are obtained after discretization of partial differential equations using finite element methods. The authors provide a systematic presentation of the recent advances in robust algebraic multilevel methods and algorithms, e.g., the preconditioned conjugate gradient method, algebraic multilevel iteration (AMLI) preconditioners, the classical algebraic multigrid (AMG) method and its recent modifications, namely AMG using element interpolation (AMGe) and AMG based on smoothed aggregation. The first six chapters can serve as a short introductory course on the theory of AMLI methods and algorithms. The next part of the monograph is devoted to more advanced topics, including the description of new generation AMG methods, AMLI methods for discontinuous Galerkin systems, looking-free algorithms for coupled problems etc., ending with important practical issues of implementation and challenging applications. This second part is addressed to some more experienced students and practitioners and can be used to complete a more advanced course on robust AMLI and AMG methods and their efficient application. This book is intended for mathematicians, engineers, natural scientists etc. Radon series on computational and applied mathematics ;5.Algebras, LinearData processingMathematical analysisLinear Algebra.Multigrid Method.Partial Differential Equation.Algebras, LinearData processing.Mathematical analysis.515.35SK 540rvkKraus Johannes1544395Margenov Svetozar1544396MiAaPQMiAaPQMiAaPQBOOK9910778468003321Robust algebraic multilevel methods and algorithms3798596UNINA
