Available in PDF, EPUB and Kindle. Book excerpt: Ce travail se scinde principalement en deux grandes composantes ; l'une de type théorique et l'autre de type numérique. Dans la partie théorique, on se place dans le cadre de l'optimisation non linéaire avec contraintes. La globalisation d'un algorithme de points intérieurs par des régions de confiance est examinée et l'on détaille ses propriétés de convergence, étayées par des expérimentations numériques sur des problèmes de programmation quadratique. Sous des hypothèses du premier et second ordre, les propriétés de convergence locale, asymptotique, d'une classe d'algorithmes de points intérieurs, parmi laquelle l'algorithme précédent, sont étudiées et l'on montre que l'on peut obtenir une convergence sous-quadratique qui a lieu en composantes. Les résultats sont généralisés à un taux de convergence arbitrairement élevé, au prix de la résolution d'un nombre suffisamment élevé de systèmes de Newton pour chaque valeur du paramètre barrière. Ces résultats asymptotiques supposent que la condition de qualification des contraintes d'indépendance des gradients actifs est satisfaite. Il s'avère que la condition de qualification des contraintes peut être relachée en la condition de Mangasarian et Fromowitz, tout en conservant les propriétés de convergence importantes. Les techniques utilisées et les résultats de convergence asymptotique en les composantes sont enfin généralisés à la résolution de systèmes d'équations non linéaires de rang plein. Dans la composante numérique, on examine ensuite l'environnement CUTE et l'on décrit les nouvelles fonctionnalités et les apports de CUTEr.

This book was released on 2008-01-22 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Herb Keller suggested, more than two years ago, that we update our lectures held at the Tata Institute of Fundamental Research in 1977, and then have it published in the collection Springer Series in Computational Physics, we thought, at first, that it would be an easy task. Actually, we realized very quickly that it would be more complicated than what it seemed at first glance, for several reasons: 1. The first version of Numerical Methods for Nonlinear Variational Problems was, in fact, part of a set of monographs on numerical mat- matics published, in a short span of time, by the Tata Institute of Fun- mental Research in its well-known series Lectures on Mathematics and Physics; as might be expected, the first version systematically used the material of the above monographs, this being particularly true for Lectures on the Finite Element Method by P. G. Ciarlet and Lectures on Optimization—Theory and Algorithms by J. Cea. This second version had to be more self-contained. This necessity led to some minor additions in Chapters I-IV of the original version, and to the introduction of a chapter (namely, Chapter Y of this book) on relaxation methods, since these methods play an important role in various parts of this book.

Download or read book Optimisation Numerique written by J.-Frédéric Bonnans and published by Mathématiques et Applications. This book was released on 1997-09-25 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce livre est exclusivement consacré aux algorithmes numériques d'optimisation (quasi-Newton, faisceaux, programmation quadratique successive, points intérieurs); les bases théoriques (conditions d'optimalité, multiplicateurs de Lagrange) sont supposées connues. Son but est de familiariser le lecteur avec ces algorithmes, qui sont pour la plupart bien classiques. Leur description insiste sur leur implémentation numérique, ils peuvent être programmés directement par un lecteur expérimenté. Le côté théorique n'est pas pour autant négligé, avec démonstration de chaque théorème de convergence ou vitesse de convergence; souvent, ces démonstrations utilisent des hypothèses minimales.

Download or read book Nonlinear Programming and Variational Inequality Problems written by Michael Patriksson and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since I started working in the area of nonlinear programming and, later on, variational inequality problems, I have frequently been surprised to find that many algorithms, however scattered in numerous journals, monographs and books, and described rather differently, are closely related to each other. This book is meant to help the reader understand and relate algorithms to each other in some intuitive fashion, and represents, in this respect, a consolidation of the field. The framework of algorithms presented in this book is called Cost Approxi mation. (The preface of the Ph.D. thesis [Pat93d] explains the background to the work that lead to the thesis, and ultimately to this book.) It describes, for a given formulation of a variational inequality or nonlinear programming problem, an algorithm by means of approximating mappings and problems, a principle for the update of the iteration points, and a merit function which guides and monitors the convergence of the algorithm. One purpose of this book is to offer this framework as an intuitively appeal ing tool for describing an algorithm. One of the advantages of the framework, or any reasonable framework for that matter, is that two algorithms may be easily related and compared through its use. This framework is particular in that it covers a vast number of methods, while still being fairly detailed; the level of abstraction is in fact the same as that of the original problem statement.

This book was released on 1980-06-01 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume are twenty-eight papers from the Conference on Nonlinear Partial Differential Equationsin Engineering and Applied Science, sponsored by the Office of Naval Research and held at the Universityof Rhode Island in June, 1979. Included are contributions from an international group of distinguishedmathematicians, scientists, and engineers coming from a wide variety of disciplines and having a commoninterest in the application of mathematics, particularly nonlinear partial differential equations, to realworld problems.The subject matter ranges from almost purely mathematical topics in numerical analysis and bifurcationtheory to a host of practical applications that involve nonlinear partial differential equations, suchas fluid dynamics, nonlinear waves, elasticity, viscoelasticity, hyperelasticity, solitons, metallurgy, shocklessairfoil design, quantum fields, and Darcy's law on flows in porous media.Non/inear Partial Differential Equations in Engineering and Applied Science focuses on a variety oftopics of specialized, contemporary concern to mathematicians, physical and biological scientists, andengineers who work with phenomena that can be described by nonlinear partial differential equations.

Available in PDF, EPUB and Kindle. Book excerpt: Control of Distributed Parameter Systems 1982 covers the proceeding of the Third International Federation of Automatic Control (IFAC) Symposium on Control of Distributed Parameter Systems. The book reviews papers that tackle issues concerning the control of distributed parameter systems, such as modeling, identification, estimation, stabilization, optimization, and energy system. The topics that the book tackles include notes on optimal and estimation result of nonlinear systems; approximation of the parameter identification problem in distributed parameters systems; and optimal control of a punctually located heat source. This text also encompasses the stabilization of nonlinear parabolic equations and the decoupling approach to the control of large spaceborne antenna systems. Stability of Hilbert space contraction semigroups and the tracking problem in the fractional representation approach are also discussed. This book will be of great interest to researchers and professionals whose work concerns automated control systems.
