arXiv 2025年
作者: Jiao, Xiangmin Gao, Hongji Department of Applied Mathematics & Statistics Institute for Advanced Computational Science Stony Brook University Stony BrookNY11794 United States Department of Applied Mathematics & Statistics Stony Brook University Stony BrookNY11794 United States
We propose P-order (Power-order), a unified, norm-independent framework for quantifying the convergence rates of iterative methods. Standard analyses based on Q-order are norm-dependent and require some uniformity of ... 详细信息
