New Advancements in Swarm Algorithms: Operators and Applications

New Advancements in Swarm Algorithms: Operators and Applications

Erik Cuevas; Fernando Fausto; Adrián González

Springer Nature Switzerland AG
2019
sidottu
This book presents advances in alternative swarm development that have proved to be effective in several complex problems. Swarm intelligence (SI) is a problem-solving methodology that results from the cooperation between a set of agents with similar characteristics. The study of biological entities, such as animals and insects, manifesting social behavior has resulted in several computational models of swarm intelligence. While there are numerous books addressing the most widely known swarm methods, namely ant colony algorithms and particle swarm optimization, those discussing new alternative approaches are rare. The focus on developments based on the simple modification of popular swarm methods overlooks the opportunity to discover new techniques and procedures that can be useful in solving problems formulated by the academic and industrial communities. Presenting various novel swarm methods and their practical applications, the book helps researchers, lecturers, engineersand practitioners solve their own optimization problems.

Stochastic Optimal Control in Infinite Dimension

Stochastic Optimal Control in Infinite Dimension

Giorgio Fabbri; Fausto Gozzi; Andrzej Swiech

Springer International Publishing AG
2017
sidottu
Providing an introduction to stochastic optimal control in in?nite dimension, this book gives a complete account of the theory of second-order HJB equations in in?nite-dimensional Hilbert spaces, focusing on its applicability to associated stochastic optimal control problems. It features a general introduction to optimal stochastic control, including basic results (e.g. the dynamic programming principle) with proofs, and provides examples of applications. A complete and up-to-date exposition of the existing theory of viscosity solutions and regular solutions of second-order HJB equations in Hilbert spaces is given, together with an extensive survey of other methods, with a full bibliography. In particular, Chapter 6, written by M. Fuhrman and G. Tessitore, surveys the theory of regular solutions of HJB equations arising in in?nite-dimensional stochastic control, via BSDEs. The book is of interest to both pure and applied researchers working in the control theory of stochastic PDEs,and in PDEs in in?nite dimension. Readers from other ?elds who want to learn the basic theory will also ?nd it useful. The prerequisites are: standard functional analysis, the theory of semigroups of operators and its use in the study of PDEs, some knowledge of the dynamic programming approach to stochastic optimal control problems in ?nite dimension, and the basics of stochastic analysis and stochastic equations in in?nite-dimensional spaces.

This textbook is an introduction to Scientific Computing, in which several numerical methods for the computer-based solution of certain classes of mathematical problems are illustrated. The authors show how to compute the zeros, the extrema, and the integrals of continuous functions, solve linear systems, approximate functions using polynomials and construct accurate approximations for the solution of ordinary and partial differential equations. To make the format concrete and appealing, the programming environments Matlab and Octave are adopted as faithful companions. The book contains the solutions to several problems posed in exercises and examples, often originating from important applications. At the end of each chapter, a specific section is devoted to subjects which were not addressed in the book and contains bibliographical references for a more comprehensive treatment of the material.From the review:".... This carefully written textbook, the third English edition, contains substantial new developments on the numerical solution of differential equations. It is typeset in a two-color design and is written in a style suited for readers who have mathematics, natural sciences, computer sciences or economics as a background and who are interested in a well-organized introduction to the subject."

Calcul Scientifique

Alfio Quarteroni; Fausto Saleri; Paola Gervasio

Springer Verlag
2010
nidottu
Ce livre constitue une introduction au Calcul Scientifique. Son objectif est de présenter des méthodes numériques permettant de résoudre avec un ordinateur certains problèmes mathématiques qui ne peuvent être traités simplement avec un papier et un crayon. Les questions classiques du Calcul Scientifique sont abordées: la recherche des zéros ou le calcul d'intégrales de fonctions continues, la résolution de systèmes linéaires, l'approximation de fonctions par des polynômes, la résolution approchée d'équations différentielles. La présentation de ces méthodes est rendue vivante par le recours systématique aux environnements de programmation Matlab et Octave dont les principales commandes sont introduites progressivement. Tous les algorithmes sont présentés sous la forme de programmes. Ceci permet de vérifier très rapidement leurs propriétés théoriques, en particulier la stabilité, la précision et la complexité. La résolution de divers problèmes, souvent motivés par des applications concrètes, fait l'objet de nombreux exemples et exercices. À la fin de chaque chapitre, une section présente des aspects plus avancés et fournit des indications bibliographiques qui permettront au lecteur d'appronfondir les connaissances acquises. Le dernier chapitre est consacré à la correction des exercices proposés tout au long du livre

Solving Numerical PDEs: Problems, Applications, Exercises

Solving Numerical PDEs: Problems, Applications, Exercises

Luca Formaggia; Fausto Saleri; Alessandro Veneziani

Springer Verlag
2011
nidottu
This book stems from the long standing teaching experience of the authors in the courses on Numerical Methods in Engineering and Numerical Methods for Partial Differential Equations given to undergraduate and graduate students of Politecnico di Milano (Italy), EPFL Lausanne (Switzerland), University of Bergamo (Italy) and Emory University (Atlanta, USA). It aims at introducing students to the numerical approximation of Partial Differential Equations (PDEs). One of the difficulties of this subject is to identify the right trade-off between theoretical concepts and their actual use in practice. With this collection of examples and exercises we try to address this issue by illustrating "academic" examples which focus on basic concepts of Numerical Analysis as well as problems derived from practical application which the student is encouraged to formalize in terms of PDEs, analyze and solve. The latter examples are derived from the experience of the authors in research project developed in collaboration with scientists of different fields (biology, medicine, etc.) and industry. We wanted this book to be useful both to readers more interested in the theoretical aspects and those more concerned with the numerical implementation.

Psychological Selection and Optimal Experience Across Cultures

Psychological Selection and Optimal Experience Across Cultures

What does Western science know about the relationship between individual well-being and cultural trends? What can learn from other cultural traditions? What do the recent advancements in positive psychology teach us on this issue, particularly the eudaimonic framework, which emphasizes the connections between personal well-being and social welfare? People grow and live in cultures that deeply influence their values, aspirations and behaviors. However, individuals in their turn play an active role in building their own goals, growth trajectories and social roles, at the same time influencing culture trends. This process, defined psychological selection, is related to the individual pursuit of well-being People preferentially select and cultivate in their lives activities, interests, and relationships associated with optimal experience, a state of deep engagement, concentration, and enjoyment. Several cross-cultural studies confirmed the positive and rewarding features of optimal experience. Based on these evidences, this book offers a new perspective in the study of human behavior. Highlighting the interplay between individual and cultural growth trajectories, it conveys a core message: educating people to enjoy engagement and involvement in activities that can be relevant and meaningful for social welfare is a premise to foster the harmonious development of human communities, and the peaceful cohabitation of cultures.

La desnutrici n infantil, especialmente en ni os menores de cinco a os, es un problema que afecta gravemente el desarrollo de un pa s. Esta investigaci n busca ayudar a reducir la desnutrici n infantil, ya que la primera infancia es clave para el crecimiento f sico y el desarrollo intelectual y emocional, los cuales dependen de una nutrici n adecuada. En Ecuador, el 27,2% de los ni os menores de dos a os padece desnutrici n cr nica, lo que impacta no solo en su desarrollo, sino tambi n en la productividad del pa s a largo plazo. La falta de una alimentaci n adecuada antes de los cinco a os se traduce en menores ndices de peso y estatura, y repercute negativamente en su salud f sica e intelectual. La desnutrici n no solo se debe a la falta de alimentos, sino tambi n a la falta de conocimiento de los padres sobre c mo alimentar correctamente a sus hijos, lo que agrava los da os en el organismo, incluyendo posibles efectos negativos en el cerebro debido a la carencia de nutrientes.
