Backdoor Branching
收藏 引用
INFORMS JOURNAL ON COMPUTING 2013年 第4期25卷 693-700页
作者: Fischetti, Matteo Monaci, Michele Univ Padua Dept Informat Engn I-35131 Padua Italy
We present an exact mixed-integer programming (MIP) solution scheme where a set-covering model is used to find a small set of first-choice branching variables. In a preliminary "sampling" phase, our method q... 详细信息

On the Derivation of Continuous Piecewise Linear Approximating Functions
收藏 引用
INFORMS JOURNAL ON COMPUTING 2020年 第3期32卷 531-546页
作者: Kong, Lingxun Maravelias, Christos T. Univ Wisconsin Dept Chem & Biol Engn Madison WI 53706 USA
We propose mixed-integer programming models for fitting univariate discrete data points with continuous piecewise linear (PWL) functions. The number of approximating function segments and the locations of break points... 详细信息

Distributionally robust joint chance-constrained programming with Wasserstein metric
收藏 引用
OPTIMIZATION METHODS & SOFTWARE 2024年 第1期40卷 134-168页
作者: Gu, Yining Wang, Yanjun Shanghai Univ Finance & Econ Sch Math Shanghai Peoples R China
In this paper, we develop an exact reformulation and a deterministic approximation for distributionally robust joint chance-constrained programmings (DRCCPs) with a general class of convex uncertain constraints under ... 详细信息

A Fuzzy-Based Approach for Cholera Risk Assessment and Vaccine Allocation
收藏 引用
INTERNATIONAL JOURNAL OF FUZZY SYSTEMS 2022年 第8期24卷 3366-3383页
作者: Qasem, Ahmed Gailan Lam, Sarah S. Aqlan, Faisal SUNY Binghamton Dept Syst Sci & Ind Engn Binghamton NY 13902 USA Univ Louisville Dept Ind Engn Louisville KY 40292 USA
Common interventions to control the spread of cholera include improving sanitation, hygiene, and access to safe drinking water and providing epidemic regions with sufficient treatment kits and oral vaccines. Due to re... 详细信息

Bilinear matrix equation characterizes Laplacian and distance matrices of weighted trees

DISCRETE APPLIED MATHEMATICS 2021年 305卷 1-9页
作者: Goubko, Mikhail Veremyev, Alexander RAS VA Trapeznikov Inst Control Sci 65 Profsoyuznaya Moscow 117997 Russia Univ Cent Florida Orlando FL 32816 USA
It is known from algebraic graph theory that if L is the Laplacian matrix of some tree G with a vertex degree sequence d = (delta(1),..., delta(n)). and D is its distance matrix, then LD + 2I = (2 center dot 1 - d)1(i... 详细信息

Minimizing a sum of clipped convex functions
收藏 引用
OPTIMIZATION LETTERS 2020年 第8期14卷 2443-2459页
作者: Barratt, Shane Angeris, Guillermo Boyd, Stephen Stanford Univ Dept Elect Engn Stanford CA 94305 USA
We consider the problem of minimizing a sum of clipped convex functions. Applications of this problem include clipped empirical risk minimization and clipped control. While the problem of minimizing the sum of clipped... 详细信息

Lagrangian Heuristics for Large-Scale Dynamic Facility Location with Generalized Modular Capacities
收藏 引用
INFORMS JOURNAL ON COMPUTING 2017年 第3期29卷 388-404页
作者: Jena, Sanjay Dominik Cordeau, Jean-Francois Gendron, Bernard Univ Montreal CIRRELT Montreal PQ H3C 3J7 Canada Univ Montreal Dept Informat & Rech Operat Montreal PQ H3C 3J7 Canada HEC Montreal CIRRELT Montreal PQ H3T 2A7 Canada HEC Montreal Canada Res Chair Logist & Transportat Montreal PQ H3T 2A7 Canada
We consider the dynamic facility location problem with generalized modular capacities, a multiperiod facility location problem in which the costs for capacity changes may differ for all pairs of capacity levels. The p... 详细信息

On parallelizing dual decomposition in stochastic integer programming
收藏 引用
OPERATIONS RESEARCH LETTERS 2013年 第3期41卷 252-258页
作者: Lubin, Miles Martin, Kipp Petra, Cosmin G. Sandikci, Burhaneddin Argonne Natl Lab Math & Comp Sci Div Argonne IL 60439 USA Univ Chicago Booth Sch Business Chicago IL 60637 USA
For stochastic mixed-integer programs, we revisit the dual decomposition algorithm of Came and Schultz from a computational perspective with the aim of its parallelization. We address an important bottleneck of parall... 详细信息

COMPUTATIONAL OPTIMIZATION AND APPLICATIONS 2022年 第3期83卷 759-800页
作者: Yang, Dominic Balaprakash, Prasanna Leyffer, Sven Univ Calif Los Angeles Los Angeles CA 90095 USA Argonne Natl Lab Lemont IL USA
We consider nonlinear optimization problems that involve surrogate models represented by neural networks. We demonstrate first how to directly embed neural network evaluation into optimization models, highlight a diff... 详细信息
