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

OPERATIONS RESEARCH LETTERS 2001年 第2期29卷 87-92页
作者: Sun, XL Li, D Chinese Univ Hong Kong Dept Syst Engn & Engn Management Shatin Hong Kong Peoples R China Shanghai Univ Dept Math Shanghai 200436 Peoples R China
A bound is obtained in this note for the distance between the integer and real solutions to convex quadratic programs. This bound is a function of the condition number of the Hessian matrix. We further extend this pro... 详细信息
