Representing quadratically constrained quadratic programs as generalized copositive programs
收藏 引用
OPERATIONS RESEARCH LETTERS 2012年 第3期40卷 203-206页
作者: Burer, Samuel Dong, Hongbo Univ Wisconsin Wisconsin Inst Discovery Madison WI 53715 USA Univ Iowa Dept Management Sci Iowa City IA 52242 USA
We show that any (nonconvex) quadratically constrained quadratic program (QCQP) can be represented as a generalized copositive program. In fact, we provide two representations: one based on the concept of completely p... 详细信息

Robust and low-order design of flexible AC transmission systems and power system stabilisers for oscillation damping
收藏 引用
IET GENERATION TRANSMISSION & DISTRIBUTION 2012年 第5期6卷 445-452页
作者: Simfukwe, D. D. Pal, B. C. Jabr, R. A. Martins, N. Univ London Imperial Coll Sci Technol & Med Dept Elect & Elect Engn London SW7 2AZ England Amer Univ Beirut Dept Elect & Comp Engn Beirut 11072020 Lebanon Electrobras CEPEL BR-21941911 Rio De Janeiro RJ Brazil
The study presents a method for the coordinated design of low-order robust controllers for stabilising power system oscillations. The design uses conic programming to shift under-damped or unstable modes into a region... 详细信息

SIAM JOURNAL ON OPTIMIZATION 2012年 第2期22卷 628-648页
作者: Bampou, Dimitra Kuhn, Daniel Univ London Imperial Coll Sci Technol & Med Dept Comp London SW7 2BZ England
Continuous linear programs have attracted considerable interest due to their potential for modeling manufacturing, scheduling, and routing problems. While efficient simplex-type algorithms have been developed for sepa... 详细信息

Full Nesterov-Todd step infeasible interior-point method for symmetric optimization
收藏 引用
EUROPEAN JOURNAL OF OPERATIONAL RESEARCH 2011年 第3期214卷 473-484页
作者: Gu, G. Zangiabadi, M. Roos, C. Nanjing Univ Dept Math Nanjing Peoples R China Shahrekord Univ Dept Math Sci Shahrekord Iran Delft Univ Technol Fac Elect Engn Math & Comp Sci NL-2600 AA Delft Netherlands
Euclidean Jordan algebras were proved more than a decade ago to be an indispensable tool in the unified study of interior-point methods. By using it, we generalize the full-Newton step infeasible interior-point method... 详细信息

FAST METHODS FOR COMPUTING THE p-RADIUS OF MATRICES
收藏 引用
SIAM JOURNAL ON SCIENTIFIC COMPUTING 2011年 第3期33卷 1246-1266页
作者: Jungers, Raphael M. Protasov, Vladimir Y. MIT Informat & Decis Syst Lab Cambridge MA 02139 USA Moscow MV Lomonosov State Univ Dept Mech & Math Moscow 119992 Russia
The p-radius characterizes the average rate of growth of norms of matrices in a multiplicative semigroup. This quantity has found several applications in recent years. We raise the question of its computability. We pr... 详细信息

SELF-CONCORDANCE AND DECOMPOSITION-BASED INTERIOR POINT METHODS FOR THE TWO-STAGE STOCHASTIC CONVEX OPTIMIZATION PROBLEM
收藏 引用
SIAM JOURNAL ON OPTIMIZATION 2011年 第4期21卷 1667-1687页
作者: Chen, Michael Mehrotra, Sanjay York Univ Dept Math & Stat Toronto ON M3J 1P3 Canada York Univ Dept Math & Stat Toronto ON M3J 1P3 Canada Northwestern Univ Dept IE MS Evanston IL 60208 USA
We study the two-stage stochastic convex optimization problem whose first-and second-stage feasible regions admit a self-concordant barrier. We show that the barrier recourse functions and the composite barrier functi... 详细信息

MATHEMATICAL programming 2010年 第1期122卷 1-20页
作者: Atamtuerk, Alper Narayanan, Vishnu Univ Calif Berkeley Dept Ind Engn & Operat Res Berkeley CA 94720 USA
A conic integer program is an integer programming problem with conic constraints. Many problems in finance, engineering, statistical learning, and probabilistic optimization are modeled using conic constraints. Here w... 详细信息

EUROPEAN JOURNAL OF OPERATIONAL RESEARCH 2010年 第3期207卷 1210-1220页
作者: Sun, Jie Zhang, Su Natl Univ Singapore Dept Decis Sci Singapore 119245 Singapore Natl Univ Singapore Risk Management Inst Singapore 119245 Singapore Nankai Univ Sch Business Inst Modern Management Tianjin Peoples R China
We propose a modified alternating direction method for solving convex quadratically constrained quadratic semidefinite optimization problems. The method is a first-order method, therefore requires much less computatio... 详细信息
