Abstract :
In this paper an algebraic multilevel method is discussed that mainly focuses on the use of a sparse approximate inverse smoother. In particular strategies are presented to adapt the sparse approximate inverse smoother to a given problem.

Keywords : sparse approximate inverse, large sparse matrices, algebraic multilevel method
