A complete pivoting strategy for the right-looking Robust Incomplete Factorization preconditioner

In this paper, we use a complete pivoting strategy for the right-looking version of Robust Incomplete Factorization preconditioner (Benzi and Tůma, 2003) [7]. The new preconditioner has been used as the right preconditioner for several linear systems and its effectiveness has been studied.
