Hierarchical search strategy for a team of autonomous vehicles
收藏 引用
IFAC Proceedings Volumes 2004年 第8期37卷 567-572页
作者: Jorge Silva Alberto Speranzon João Borges de Sousa Karl Henrik Johansson Instituto Superior de Engenharia do Porto Rua Dr. Antonio Bernardino de Almeida 431 4200-072 Porto Portugal Dept. of Signals Sensors & Systems Royal Institute of Technology SE-100 44 Stockholm Sweden Faculdade de Engenharia da Universidade do Porto Rua Dr. Roberto Frias 4200-465 Porto Portugal
A multi-vehicle search strategy based on the simplex algorithm is proposed. The strategy is mapped into a hierarchical scheme with three layers. The upper layer is described by a discrete-event system. The output of t... 详细信息

A global optimization heuristic for estimating agent based models
收藏 引用
COMPUTATIONAL STATISTICS & DATA ANALYSIS 2003年 第3期42卷 299-312页
作者: Gilli, M Winker, P Univ Geneva Dept Econometr CH-1211 Geneva 4 Switzerland FAME CH-1211 Geneva Switzerland Int Univ Germany Dept Econ & Quantitat Methods D-76646 Bruchsal Germany
A continuous global optimization heuristic for a stochastic approximation of an objective function, which itself is not globally convex, is introduced. The objective function arises from the simulation based indirect ... 详细信息

Docking studies of matrix metalloproteinase inhibitors: zinc parameter optimization to improve the binding free energy prediction
收藏 引用
JOURNAL OF MOLECULAR GRAPHICS & MODELLING 2003年 第2期22卷 115-126页
作者: Hu, X Shelver, WH N Dakota State Univ Dept Pharmaceut Sci Fargo ND 58105 USA
Docking of metalloproteinase inhibitors remains a challenge due to the zinc multiple coordination geometries and the lack of appropriate force field parameters to model the metal/ligand interactions. In this study, we... 详细信息

A LAGRANGIAN RELAXATION APPROACH FOR SUPPLY CHAIN PLANNING WITH ORDER/SETUP COSTS AND CAPACITY CONSTRAINTS
收藏 引用
Systems Science and Systems Engineering 2003年 第1期12卷 98-110页
作者: Haoxun CHEN Chengbin CHUIndustrial System Optimization Laboratory Technology University of Troyes, France Industrial System Optimization Laboratory Technology University of Troyes
A heuristic approach is developed for supply chain planning modeled as multi-item multi-level capacitated lot sizing problems. The heuristic combines Lagrangian relaxation (LR) with local search. Different from existi... 详细信息

RANDOM STRUCTURES & algorithmS 2003年 第4期23卷 453-471页
作者: Gärtner, B Tschirschnitz, F Welzl, E Solymosi, J Valtr, P ETH Zentrum ETH Zurich Inst Theoret Informat CH-8092 Zurich Switzerland Univ British Columbia Dept Math Vancouver BC V6T 1Z2 Canada Charles Univ Dept Math Appl Prague 11800 1 Czech Republic
We analyze a randomized pivoting process involving one line and n points in the plane. The process models the behavior of the RANDOM-EDGE simplex algorithm on simple polytopes with it facets in dimension n - 2. We obt... 详细信息

Generalized column generation for linear programming
收藏 引用
MANAGEMENT SCIENCE 2002年 第3期48卷 444-452页
作者: Oguz, O Bilkent Univ Dept Ind Engn Ankara Turkey
Column generation is a well-known and widely practiced technique for solving linear programs with too many variables or constraints to include in the initial formulation explicitly. Instead, the required column inform... 详细信息
