MATHEMATICS OF OPERATIONS RESEARCH 2021年 第3期46卷 1054-1080页
作者: Ahmadi, Amir Ali El Khadir, Bachir Princeton Univ Dept Operat Res & Financial Engn Princeton NJ 08544 USA
We study time-varying semidefinite programs (TV-SDPs), which are semidefinite programs whose data (and solutions) are functions of time. Our focus is on the setting where the data vary polynomially with time. We show ... 详细信息

IFAC Proceedings Volumes 2003年 第11期36卷 199-204页
作者: Ragnar Wallin Anders Hansson Lieven Vandenberghe Department of Electrical Engineering Division of Automatic Control Linköping University SE-581 83 Linköping Sweden Electrical Engineering Department University of California Los Angeles Los Angeles CA 90095-1594 USA
As the semidefinite programs that result from integral quadratic constraints are usually large it is important to implement efficient algorithms. The interior-point algorithms in this paper are primal-dual potential r... 详细信息
