MULTIGRID METHODS:AN ALTERNATE VIEWPOINT

摘要

Research activity in the numerical solution of elliptic partial differential boundary value problems is experiencing a revolution of sorts in the form of multigrid methods. Although primitive forms of these methods have actually been known for some time, they have been given very little attention until recently. The new surge of activity is due primarily to the pioneering numerical work of Achi Brandt who is also extending these methods to apply to problems in such areas as integral equations, optimization, and time dependent equations. Yet the complexity of these methods has slowed the progress of their dissemination within the technical community.
