“…, σ (m)} is the indexes set used in an IPM iteration for the SP construction, an advantageous property of this preconditioner is that the same indexes may be reused by several iterations making these iterations much cheaper. The papers [1,5,9,19] study the choice of basic indexes for a preconditioner.…”

“…A abordagem híbrida de precondicionamento se mostrou uma ferramenta bastante útil para a resolução de sistemas lineares oriundos do método de pontos interiores, os quais são resolvidos pelo método iterativo do gradiente conjugado. Isto pode ser visto conforme os resultados apresentados nos trabalhos em (BOCANEGRA, 2005b;GHIDINI;OLIVEIRA;SORENSEN, 2014;SUÑAGUA;OLIVEIRA, 2016;BARTMEYER, 2016), dentre outros. Esta estratégia consiste em combinar dois ou mais precondicionadores distintos com intuito de melhorar a eficiência do método iterativo.…”
