Subspace-Modeling-Based Nonlinear Measurement for Process Design
收藏 引用
INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH 2011年 第23期50卷 13457-13465页
作者: Lu, XinJiang Huang, MingHui Li, YiBo Chen, Min Cent S Univ State Key Lab High Performance Complex Mfg Changsha 410083 Hunan Peoples R China
In industry, many nonlinear processes can be approximated well by a linear model under a suitable design parameter, upon which a linear controller can effectively control these processes. The key problem is how to fin... 详细信息

MATHEMATICAL programming 2011年 第2期129卷 285-299页
作者: Ge, Dongdong Jiang, Xiaoye Ye, Yinyu Shanghai Jiao Tong Univ Antai Sch Econ & Management Shanghai 200052 Peoples R China Stanford Univ Inst Computat & Math Engn Stanford CA 94305 USA Stanford Univ Dept Management Sci & Engn Stanford CA 94305 USA
We discuss the L-p (0 <= p < 1) minimization problem arising from sparse solution construction and compressed sensing. For any fixed 0 < p < 1, we prove that finding the global minimal value of the problem... 详细信息

SET-VALUED AND VARIATIONAL ANALYSIS 2011年 第4期19卷 589-608页
作者: Zaslavski, Alexander J. Technion Israel Inst Technol Dept Math IL-32000 Haifa Israel
We study the local convergence of a proximal point method in a metric space under the presence of computational errors. We show that the proximal point method generates a good approximate solution if the sequence of c... 详细信息

AUTOMATION AND REMOTE CONTROL 2011年 第6期72卷 1271-1281页
作者: Srochko, V. A. Rozinova, N. S. Irkutsk State Univ Irkutsk 664003 Russia
Problems of control are considered, for which the maximum principle releases extremal modes and points of the set of accessibility without optimality guaranty. In the framework of technology of the confidence region a... 详细信息

An inexact Newton method for nonconvex equality constrained optimization
收藏 引用
MATHEMATICAL programming 2010年 第2期122卷 273-299页
作者: Byrd, Richard H. Curtis, Frank E. Nocedal, Jorge Northwestern Univ Dept Ind Engn & Management Sci Evanston IL 60208 USA Univ Colorado Dept Comp Sci Boulder CO 80309 USA Northwestern Univ Dept Elect Engn & Comp Sci Evanston IL 60208 USA
We present a matrix-free line search algorithm for large-scale equality constrained optimization that allows for inexact step computations. For strictly convex problems, the method reduces to the inexact sequential qu... 详细信息
