IMPROVED conic REFORMULATIONS FOR K-MEANS CLUSTERING
收藏 引用
SIAM JOURNAL ON OPTIMIZATION 2018年 第4期28卷 3105-3126页
作者: Prasad, Madhushini Narayana Hanasusanto, Grani A. Univ Texas Austin Grad Program Operat Res & Ind Engn Austin TX 78712 USA
In this paper, we show that the popular K-means clustering problem can equivalently be reformulated as a conic program of polynomial size. The arising convex optimization problem is NP-hard, but amenable to a tractabl... 详细信息

Limit analysis, rammed earth material and Casagrande test
收藏 引用
COMPTES RENDUS MECANIQUE 2018年 第2期346卷 98-109页
作者: El-Nabouch, Ranime Pastor, Joseph Quoc-Bao Bui Ple, Olivier Univ Savoie Mt Blanc CNRS LOCIE F-73000 Chambery France Ton Duc Thang Univ Fac Civil Engn Ho Chi Minh City Vietnam
The present paper is concerned with the simulation of the Casagrande test carried out on a rammed earth material for wall-type structures in the framework of Limit Analysis (LA). In a preliminary study, the material i... 详细信息

Primal interior-point decomposition algorithms for two-stage stochastic extended second-order cone programming
收藏 引用
OPTIMIZATION 2018年 第12期67卷 2291-2323页
作者: Alzalg, Baha Univ Jordan Dept Math Amman 11942 Jordan
We study and solve the two-stage stochastic extended second-order cone programming problem. We show that the barrier recourse functions and the composite barrier functions for this optimization problem are self-concor... 详细信息

INTERNATIONAL JOURNAL OF COMPUTATIONAL METHODS 2019年 第5期16卷
作者: Ho, P. L. H. Le, C., V Chu, T. Q. Univ Tech Educ HCMC Fac Appl Mech & Civil Engn Ho Chi Minh City Vietnam Int Univ VNU HCM Dept Civil Engn Ho Chi Minh City Vietnam
This paper presents a novel equilibrium formulation, that uses the cell-based smoothed method and conic programming, for limit and shakedown analysis of structures. The virtual strains are computed using straining cel... 详细信息

Strong Stationarity for Optimization Problems with Complementarity Constraints in Absence of Polyhedricity With Applications to Optimization with Semidefinite and Second-Order-Cone Complementarity Constraints
收藏 引用
SET-VALUED AND VARIATIONAL ANALYSIS 2017年 第1期25卷 133-175页
作者: Wachsmuth, Gerd Tech Univ Chemnitz Fac Math Professorship Numer Math Partial Differential Equ D-09107 Chemnitz Germany
We consider mathematical programs with complementarity constraints in Banach spaces. In particular, we focus on the situation that the complementarity constraint is defined by a non-polyhedric cone K. We demonstrate h... 详细信息

Mixed integer programming with a class of nonlinear convex constraints
收藏 引用
DISCRETE OPTIMIZATION 2017年 24卷 66-86页
作者: Vinel, Alexander Krokhmal, Pavlo A. Auburn Univ Dept Ind & Syst Engn Shelby Ctr 3301 Auburn AL 36849 USA Univ Arizona Dept Syst & Ind Engn 1127 E James E Rogers Way Tucson AZ 85721 USA
We study solution approaches to a class of mixed-integer nonlinear programming problems that arise from recent developments in risk-averse stochastic optimization and contain second- and p-order cone programming as sp... 详细信息

A semi-smooth Newton method for projection equations and linear complementarity problems with respect to the second order cone
收藏 引用
LINEAR ALGEBRA AND ITS APPLICATIONS 2017年 513卷 160-181页
作者: Cruz, J. Y. Bello Ferreira, O. P. Nemeth, S. Z. Prudente, L. F. Northern Illinois Univ Dept Math Sci WH 366 De Kalb IL 60115 USA Univ Fed Goias IME Ave Esperanga S-NCampus Samambaia BR-74690900 Goiania Go Brazil Univ Birmingham Sch Math Watson Bldg Birmingham B15 2TT W Midlands England
In this paper a special semi-smooth equation associated to the second order cone is studied. It is shown that, under mild assumptions, the semi-smooth Newton method applied to this equation is well-defined and the gen... 详细信息
