A class of generic factored and multi-level recursive approximate inverse techniques for solving general sparse systems

Purpose – The purpose of this paper is to propose novel factored approximate sparse inverse schemes and multi-level methods for the solution of large sparse linear systems. Design/methodology/approach – The main motive for the derivation of the various generic preconditioning schemes lies to the eff...
