Available in PDF, EPUB and Kindle. Book excerpt: Les métaheuristiques sont des algorithmes génériques, souvent inspirés de la nature, conçues pour résoudre des problèmes d'optimisation complexes. Parmi les métaheuristiques les plus récentes, nous retenons celle basée sur la théorie de la biogéographie insulaire: Biogeography-based optimization (BBO).Dans cette thèse, nous considérons à la fois les problèmes d'optimisation globale à variables continues avec et sans contraintes. De nouvelles versions hybrides de BBO sont proposées comme des solutions très prometteuses pour résoudre les problèmes considérés. Les méthodes proposées visent à pallier les inconvénients de la convergence lente et du manque de diversité de l'algorithme BBO. Dans la première partie de cette thèse, nous présentons la méthode que nous avons développée, issue d'une hybridation de BBO avec l'évolution différentielle (DE) pour résoudre des problèmes d'optimisation sans contraintes. Nous montrons que les résultats de l'algorithme proposé sont plus précis, notamment pour des problèmes multimodaux, qui sont parmi les problèmes les plus difficiles pour de nombreux algorithmes d'optimisation. Pour résoudre des problèmes d'optimisation sous contraintes, nous proposons trois nouvelles variantes de BBO. Des expérimentations ont été menées pour rendre compte de l'utilité des méthodes proposées. Dans une deuxième partie, nous nous intéressons à l'étude des capacités des méthodes proposées à résoudre des problèmes d'optimisation, issus du monde réel. Nous nous proposons d'abord de résoudre le problème d'allocation optimale de puissance pour la détection décentralisée d'un signal déterministe dans un réseau de capteurs sans fil, compte tenu des fortes contraintes en ressources énergétiques et en bande passante des noeuds répartis. L'objectif est de minimiser la puissance totale allouée aux capteurs, tout en gardant la probabilité d'erreur de détection au dessous d'un seuil requis. Dans un deuxième temps, nous nous focalisons sur la segmentation d'images en niveaux de gris par seuillage multi-niveaux. Les seuils sont déterminés de manière à maximiser l'entropie floue. Ce problème d'optimisation est résolu en appliquant une variante de BBO (DBBO-Fuzzy) que nous avons développée. Nous montrons l'efficacité de la méthode proposée aux travers de résultats expérimentaux.

Download or read book Reactive Search and Intelligent Optimization written by Roberto Battiti and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reactive Search and Intelligent Optimization is an excellent introduction to the main principles of reactive search, as well as an attempt to develop some fresh intuition for the approaches. The book looks at different optimization possibilities with an emphasis on opportunities for learning and self-tuning strategies. While focusing more on methods than on problems, problems are introduced wherever they help make the discussion more concrete, or when a specific problem has been widely studied by reactive search and intelligent optimization heuristics. Individual chapters cover reacting on the neighborhood; reacting on the annealing schedule; reactive prohibitions; model-based search; reacting on the objective function; relationships between reactive search and reinforcement learning; and much more. Each chapter is structured to show basic issues and algorithms; the parameters critical for the success of the different methods discussed; and opportunities for the automated tuning of these parameters.

This book was released on 2014-07-14 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will present the papers delivered at the first U.S. conference devoted exclusively to global optimization and will thus provide valuable insights into the significant research on the topic that has been emerging during recent years. Held at Princeton University in May 1991, the conference brought together an interdisciplinary group of the most active developers of algorithms for global optimization in order to focus the attention of the mathematical programming community on the unsolved problems and diverse applications of this field. The main subjects addressed at the conference were advances in deterministic and stochastic methods for global optimization, parallel algorithms for global optimization problems, and applications of global optimization. Although global optimization is primarily a mathematical problem, it is relevant to several other disciplines, including computer science, applied mathematics, physical chemistry, molecular biology, statistics, physics, engineering, operations research, communication theory, and economics. Global optimization problems originate from a wide variety of mathematical models of real-world systems. Some of its applications are allocation and location problems and VLSI and data-base design problems. Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Download or read book Metaheuristics for Production Scheduling written by Bassem Jarboui and published by John Wiley & Sons. This book was released on 2013-06-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the potentialities of metaheuristics for solving production scheduling problems and the relationship between these two fields. For the past several years, there has been an increasing interest in using metaheuristic methods to solve scheduling problems. The main reasons for this are that such problems are generally hard to solve to optimality, as well as the fact that metaheuristics provide very good solutions in a reasonable time. The first part of the book presents eight applications of metaheuristics for solving various mono-objective scheduling problems. The second part is itself split into two, the first section being devoted to five multi-objective problems to which metaheuristics are adapted, while the second tackles various transportation problems related to the organization of production systems. Many real-world applications are presented by the authors, making this an invaluable resource for researchers and students in engineering, economics, mathematics and computer science. Contents 1.

Download or read book Using OpenMP written by Barbara Chapman and published by MIT Press. This book was released on 2007-10-12 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive overview of OpenMP, the standard application programming interface for shared memory parallel computing—a reference for students and professionals. "I hope that readers will learn to use the full expressibility and power of OpenMP. This book should provide an excellent introduction to beginners, and the performance section should help those with some experience who want to push OpenMP to its limits." —from the foreword by David J. Kuck, Intel Fellow, Software and Solutions Group, and Director, Parallel and Distributed Solutions, Intel Corporation OpenMP, a portable programming interface for shared memory parallel computers, was adopted as an informal standard in 1997 by computer scientists who wanted a unified model on which to base programs for shared memory systems. OpenMP is now used by many software developers; it offers significant advantages over both hand-threading and MPI. Using OpenMP offers a comprehensive introduction to parallel programming concepts and a detailed overview of OpenMP. Using OpenMP discusses hardware developments, describes where OpenMP is applicable, and compares OpenMP to other programming interfaces for shared and distributed memory parallel architectures. It introduces the individual features of OpenMP, provides many source code examples that demonstrate the use and functionality of the language constructs, and offers tips on writing an efficient OpenMP program. It describes how to use OpenMP in full-scale applications to achieve high performance on large-scale architectures, discussing several case studies in detail, and offers in-depth troubleshooting advice. It explains how OpenMP is translated into explicitly multithreaded code, providing a valuable behind-the-scenes account of OpenMP program performance. Finally, Using OpenMP considers trends likely to influence OpenMP development, offering a glimpse of the possibilities of a future OpenMP 3.0 from the vantage point of the current OpenMP 2.5. With multicore computer use increasing, the need for a comprehensive introduction and overview of the standard interface is clear. Using OpenMP provides an essential reference not only for students at both undergraduate and graduate levels but also for professionals who intend to parallelize existing codes or develop new parallel programs for shared memory computer architectures.
