PROBING THE PARETO FRONTIER FOR BASIS PURSUIT SOLUTIONS
收藏 引用
SIAM JOURNAL ON SCIENTIFIC COMPUTING 2008年 第2期31卷 890-912页
作者: van den Berg, Ewout Friedlander, Michael P. Univ British Columbia Dept Comp Sci Vancouver BC V6T 1Z4 Canada
The basis pursuit problem seeks a minimum one-norm solution of an underdetermined least-squares problem. Basis pursuit denoise (BPDN) fits the least-squares problem only approximately, and a single parameter determine... 详细信息

JOURNAL OF GLOBAL OPTIMIZATION 2008年 第4期40卷 589-621页
作者: Zhao, Y. B. Fang, S. -C. Lavery, J. E. N Carolina State Univ Raleigh NC 27695 USA Chinese Acad Sci Inst Appl Math AMSS Beijing 100080 Peoples R China Tsinghua Univ Dept Math Sci & Ind Engn Beijing 100084 Peoples R China USA Res Off Res Lab Div Math Res Triangle Pk NC 27709 USA
With the objective of generating "shape-preserving" smooth interpolating curves that represent data with abrupt changes in magnitude and/or knot spacing, we study a class of first-derivative-based C-1-smooth... 详细信息

Alternating offers in economic environments
收藏 引用
ECONOMICS LETTERS 2007年 第3期96卷 316-324页
作者: Houba, Harold Vrije Univ Amsterdam Tinbergen Inst Dept Econometr NL-1081 HV Amsterdam Netherlands
For positive time between proposals, stationary SPE (physical) allocations in alternating offers bargaining correspond to an asymmetric Nash bargaining solution. By the Maximum Theorem, convergence when time between p... 详细信息

Just relax: convex programming methods for identifying sparse signals in noise
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2006年 第3期52卷 1030-1051页
作者: Tropp, JA Univ Texas Inst Computat Engn & Sci Austin TX 78712 USA
This paper studies a difficult and fundamental problem that arises throughout electrical engineering, applied mathematics, and statistics. Suppose that one forms a short linear combination of elementary signals drawn ... 详细信息

Enhanced Fritz John conditions for convex programming
收藏 引用
SIAM JOURNAL ON OPTIMIZATION 2006年 第3期16卷 766-797页
作者: Bertsekas, DP Ozdaglar, AE Tseng, P MIT Dept Elect Engn & Comp Sci Cambridge MA 02139 USA Univ Washington Dept Math Seattle WA 98195 USA
We consider convex constrained optimization problems, and we enhance the classical Fritz John optimality conditions to assert the existence of multipliers with special sensitivity properties. In particular, we prove t... 详细信息

Global optimization of nonlinear fractional programming problems in engineering design
收藏 引用
ENGINEERING OPTIMIZATION 2005年 第4期37卷 399-409页
作者: Tsai, JF Natl Taiwan Univ Technol Dept Business Management Taipei 106 Taiwan
This study proposes a novel method to solve nonlinear fractional programming (NFP) problems occurring frequently in engineering design and management. Fractional terms composed of signomial functions are first decompo... 详细信息

EUROPEAN JOURNAL OF OPERATIONAL RESEARCH 2005年 第2期160卷 560-573页
作者: Li, LS Kabadi, SN Nair, KPK Univ New Brunswick Fac Adm Fredericton NB E3B 5A3 Canada
In this paper, we consider an important fuzzy version of the well known smallest covering circle problem which is also called the Euclidean 1-center problem. Here we are given a set of points in the plane whose locati... 详细信息

Tree-sparse convex programs
收藏 引用
MATHEMATICAL METHODS OF OPERATIONS RESEARCH 2003年 第3期56卷 347-376页
作者: Steinbach, MC Informat Techn Berlin Konrad Zuse Zentrum D-14195 Berlin Germany
Dynamic stochastic programs are prototypical for optimization problems with an inherent tree structure inducing characteristic sparsity patterns in the KKT systems of interior methods. We propose an integrated modelin... 详细信息
