An aggregation-based algebraic multigrid method with deflation techniques and modified generic factored approximate sparse inverses

HIGHLIGHTS

  • who: Anastasia A. Natsiou and colleagues from the School of Computing, Technological University of Dublin, H , Dublin, Ireland Kimmeria, Xanthi, Greece have published the research work: An Aggregation-Based Algebraic Multigrid Method with Deflation Techniques and Modified Generic Factored Approximate Sparse Inverses, in the Journal: Mathematics 2023, 11, 640. of /2023/
  • what: The authors examine multigrid methods for solving large systems of linear equations. of the unknown terms is applied for coarsening while deflation are proposed for improving the rate of convergence. In this work, algebraic multigrid methods were examined that are based on aggregation . . .
