摘要 最近王广彬等人讨论了在预条件因子P=I+S′作用下的预条件AOR方法,推广了他们的预条件因子,提出了一个多参数的预条件因子P_α=I+S_α,并建立了新的预条件AOR迭代法与经典的AOR迭代法的比较定理. Wang et al.[Wang G B, Zhang N, Tan F P] PreconditionedAOR Iterative Method For Z-Matrices. J Appl Math & Informatics, 2010, 28: 1409-1418] have considered the modified AOR method with a preconditioner P = I + S′. In this paper, we propose a new preconditioner P = I+Sα instead of P = I+S′, and the comparison theorems between the new preconditioned AOR method and the classical AOR are given.
