This book was released on 2004 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les métaheuristiques de colonies de fourmis s'inspirent des comportements collectifs observés chez les fourmis pour résoudre des problèmes d'optimisation difficiles. La première approche pour concevoir des métaheuristiques d'optimisation continue en suivant cette métaphore consiste à créer un système multi-agent. Nous proposons ainsi un algorithme de "colonies de fourmis interagissantes" (CIAC). La deuxième approche décrit ces métaheuristiques comme des méthodes manipulant un échantillonage d'une distribution de probabilité. Nous proposons ainsi un algorithme "à estimation de distribution" (CHEDA). En accord avec le concept de programmation à mémoire adaptative, nos algorithmes font l'objet d'une hybridation avec une recherche locale de Nelder-Mead (HCIAC). Nous avons ensuite adapté cette méthode à des problèmes continus dynamiques (DHCIAC), pour lesquels nous proposons également un nouveau jeu de test cohérent. Nos algorithmes sont enfin appliqués dans le cadre de l'automatisation du suivi des lésions de l'oeil.

Available in PDF, EPUB and Kindle. Book excerpt: Dans ce mémoire, nous présentons les méta-heuristiques inspirées du comportement des fourmis lors de la recherche de nourriture, les OCF. Nous confrontons ces méthodes face aux principales méta-heuristiques connues. Pour cela, nous proposons de nous placer sous le point de vue de l'utilisation de la mémoire et nous présentons taxinomie qui étends celle des AMP. Nous proposons deux nouvelles adaptations du modèle des fourmis. La première est l'algorithme ANTabu, il s'agit d'une méthode hybride pour la résolution du PAQ. Il associe l'utilisation des fourmis artificielles et d'une méthode de recherche locale robuste : la recherche tabou. Le parallélisme intrinsèque des systèmes de fourmis nous a amené à développer un modèle parallèle pour ANTabu. Cette méthode intègre également une puissante fonction de diversification et l'utilisation de bornes qui lui permettent d'éviter d'être piégé au niveau d'optima locaux. La seconde application développée est AP, cet algorithme est l'adaptation du modèle de coopération des fourmis à la programmation automatique. Son mécanisme de fonctionnement est simple, puisque à chaque itération on crée une nouvelle population en utilisant l'information emmagasinée par la phéromone. L'intérêt de cette gestion de l'information est qu'elle n'utilise pas de mécanismes complexes. Nous présentons cette méthode face à l'algorithme de base tel que Koza l'a défini.

Available in PDF, EPUB and Kindle. Book excerpt: L'optimisation par colonies de fourmis s'inspire du comportement collectif des fourmis dans la nature pour résoudre des problèmes d'optimisation combinatoires. Initialement proposée pour résoudre le problème du voyageur de commerce, elle a été appliquée avec succès à un grand nombre de problèmes NP-difficiles. La programmation par contraintes permet de décrire des problèmes combinatoires de façon déclarative, la résolution de ces problèmes étant prise en charge par des algorithmes intégrés au langage. Cette vision de la programmation par contraintes montre les bénéfices de l'optimisation par colonies de fourmis de manière large et novatrice ainsi que ses connections avec les principales approches existantes pour la résolution de problèmes combinatoires. Didactique, Optimisation par colonies de fourmis dresse tout d'abord un panorama des diverses méthodes pour la résolution de problèmes combinatoires et présente ensuite l'optimisation par colonies de fourmis. Des chapitres applicatifs permettent une compréhension en profondeur de ce sujet novateur. [Source : 4ème de couv.]

Download or read book Ant Colony Optimization written by Marco Dorigo and published by MIT Press. This book was released on 2004-06-04 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of the rapidly growing field of ant colony optimization that describes theoretical findings, the major algorithms, and current applications. The complex social behaviors of ants have been much studied by science, and computer scientists are now finding that these behavior patterns can provide models for solving difficult combinatorial optimization problems. The attempt to develop algorithms inspired by one aspect of ant behavior, the ability to find what computer scientists would call shortest paths, has become the field of ant colony optimization (ACO), the most successful and widely recognized algorithmic technique based on ant behavior. This book presents an overview of this rapidly growing field, from its theoretical inception to practical applications, including descriptions of many available ACO algorithms and their uses. The book first describes the translation of observed ant behavior into working optimization algorithms. The ant colony metaheuristic is then introduced and viewed in the general context of combinatorial optimization. This is followed by a detailed description and guide to all major ACO algorithms and a report on current theoretical findings. The book surveys ACO applications now in use, including routing, assignment, scheduling, subset, machine learning, and bioinformatics problems. AntNet, an ACO algorithm designed for the network routing problem, is described in detail. The authors conclude by summarizing the progress in the field and outlining future research directions. Each chapter ends with bibliographic material, bullet points setting out important ideas covered in the chapter, and exercises. Ant Colony Optimization will be of interest to academic and industry researchers, graduate students, and practitioners who wish to learn how to implement ACO algorithms.

Download or read book Hybrid Metaheuristics written by El-ghazali Talbi and published by Springer. This book was released on 2012-07-31 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main goal of this book is to provide a state of the art of hybrid metaheuristics. The book provides a complete background that enables readers to design and implement hybrid metaheuristics to solve complex optimization problems (continuous/discrete, mono-objective/multi-objective, optimization under uncertainty) in a diverse range of application domains. Readers learn to solve large scale problems quickly and efficiently combining metaheuristics with complementary metaheuristics, mathematical programming, constraint programming and machine learning. Numerous real-world examples of problems and solutions demonstrate how hybrid metaheuristics are applied in such fields as networks, logistics and transportation, bio-medical, engineering design, scheduling.

This book was released on 2020-08-14 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses a range of real-world issues including industrial activity, energy management, education, business and health. Today, technology is a part of virtually every human activity, and is used to support, monitor and manage equipment, facilities, commodities, industry, business, and individuals’ health, among others. As technology evolves, new applications, methods and techniques arise, while at the same time citizens’ expectations from technology continue to grow. In order to meet the nearly insatiable demand for new applications, better performance and higher reliability, trustworthiness, security, and power consumption efficiency, engineers must deliver smart innovations, i.e., must develop the best techniques, technologies and services in a way that respects human beings and the environment. With that goal in mind, the key topics addressed in this book are: smart technologies and artificial intelligence, green energy systems, aerospace engineering/robotics and IT, information security and mobile engineering, IT in bio-medical engineering and smart agronomy, smart marketing, management and tourism policy, technology and education, and hydrogen and fuel-cell energy technologies.

Download or read book Interaction and Market Structure written by Domenico Delli Gatti and published by Springer Science & Business Media. This book was released on 2000-03-27 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of essays which examine how the properties of aggregate variables are influenced by the actions and interactions of heterogenous individuals in different economic contexts. The common denominator of the essays is a critique of the representative agent hypothesis. If this hypothesis were correct, the behaviour of the aggregate variable would simply be the reproduction of individual optimising behaviour. In the methodology of the hard sciences, one of the achievements of the quantum revolution has been the rebuttal of the notion that aggregate behaviour can be explained on the basis of the behaviour of a single unit: the elementary particle does not even exist as a single entity but as a network, a system of interacting units. In this book, new tracks in economics which parallel the developments in physics mentioned above are explored. The essays, in fact are contributions to the analysis of the economy as a complex evolving system of interacting agents.

Download or read book Recent Advances in Global Optimization written by Christodoulos A. Floudas and published by Princeton University Press. 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.
