基于Peaceman-Rachford分裂算法,结合线性近似技术和Bregman距离,本文提出一种线性近似Bregman型Peaceman-Rachford分裂算法,用于求解目标函数带不可分结构的线性约束非凸优化问题.在常规假设下,得到算法的全局收敛性.在效益函数满足Kurdyka-Lojasiewicz性质前提下,论证算法的强收敛性.当KurdykaLojasiewicz性质关联函数为特殊结构时,分析并获得算法的收敛率结果.最后,初步数值试验说明算法有数值有效性. 相似文献

This paper discusses the two-block large-scale nonconvex optimization problem with general linear constraints.Based on the ideas of splitting and sequential quadratic optimization(SQO),a new feasible descent method for the discussed problem is proposed.First,we consider the problem of quadratic optimal(QO) approximation associated with the current feasible iteration point,and we split the QO into two small-scale QOs which can be solved in parallel.Second,a feasible descent direction for the prob... 相似文献
