Approches Hyper heuristiques appliqu es aux ench res combinatoires
Une hyper-heuristique est une methode d'optimisation de haut niveau, qui selectionne a partir d'un ensemble de methodes de resolution (appelees heuristiques de bas niveau), une heuristique appropriee a une iteration donnee. Dans notre travail nous nous sommes interesses a la resolution du probleme de la determination du gagnant dans les encheres combinatoires (WDP) en utilisant les hyper-heuristiques, ou trois approches ont ete utilisees a savoir Choice-Function, Random et une nouvelle methode hybride a savoir Stochastic Choice-Function. Ces methodes ont ete evaluees sur plusieurs benchmarks du probleme WDP de differente taille. Une comparaison est effectuee avec la methode de recherche locale stochastique (SLS), montrant que l'approche hyper-heuristique donne des resultats tres prometteurs."
Assessment and Simulation Tools for Sustainable Energy Systems
In recent years, the concept of energy has been revised and a new model based on the principle of sustainability has become more and more pervasive. The appraisal of energy technologies and projects is complex and uncertain as the related decision making has to encompass environmental, technical, economic and social factors and information sources. The scientific procedure of assessment has a vital role as it can supply the right tools to evaluate the actual situation and make realistic forecasts of the effects and outcomes of any actions undertaken. Assessment and Simulation Tools for Sustainable Energy Systems offers reviews of the main assessment and simulation methods used for effective energy assessment. Divided across three sections, Assessment and Simulation Tools for Sustainable Energy Systems develops the reader’s ability to select suitable tools to support decision making and implementation of sustainable energy projects. The first is dedicated to the analysis of theoretical foundations and applications of multi-criteria decision making. This is followed by chapters concentrating on the theory and practice of fuzzy inference, neural nets and algorithms genetics. Finally, simulation methods such as Monte Carlo analysis, mathematical programming and others are detailed. This comprehensive illustration of these tools and their application makes Assessment and Simulation Tools for Sustainable Energy Systems a key guide for researchers, scientists, managers, politicians and industry professionals developing the field of sustainable energy systems. It may also prompt further advancements in soft computing and simulation issues for students and researchers.

The Gutenberg Elegies
"[A] THOUGHTFUL AND HEARTFELT BOOK...A literary cri de coeur--a lament for literature and everything implicit in it." --The Washington Post In our zeal to embrace the wonders of the electronic age, are we sacrificing our literary culture? Renowned critic Sven Birkerts believes the answer is an alarming yes. In The Gutenberg Elegies, he explores the impact of technology on the experience of reading. Drawing on his own passionate, lifelong love of books, Birkerts examines how literature intimately shapes and nourishes the inner life. What does it mean to "hear" a book on audiotape, decipher its words on a screen, or interact with it on CD-ROM? Are books as we know them dead? At once a celebration of the complex pleasures of reading and a boldly original challenge to the new information technologies, The Gutenberg Elegies is an essential volume for anyone who cares about the past and future of books. "[A] wise and humane book....He is telling us, in short, nothing less than what reading means and why it matters." --The Boston Sunday Globe "Warmly elegiac...A candid and engaging autobiographical account sketches his own almost obsessive trajectory through avid childhood reading....This profoundly reflexive process is skillfully described." --The New York Times Book Review "Provocative...Compelling...Powerfully conveys why reading matters, why it is both a delight and a necessity." --The Harvard Review
Franï¿½ois Boucher (1703-1770) has suffered a curious fate: to have been so identified with the French Rococo as to have lost his visibility as an artist in his own right. Rethinking Boucher reclaims the artist's individuality, revealing not only the diversity of his talents but also the variety of visual and intellectual traditions with which he engaged. Part one, "The Various Boucher," examines the artist's identity in relation to his portraits and self-portraits, his ingenious genre scenes, and his overlooked religious paintings. Part two, "The Unexpected Boucher," focuses on the network of social and cultural contexts in which the artist functioned, including the commercial print market, the theaters of Paris, and the contemporary textual explorations of the exotic. The final part, "The Enlightened Boucher," discusses Boucher's work as a vehicle for Enlightenment visions of the body, whether conjured by Denis Diderot and Jean-Jacques Rousseau or Madame de Pompadour, Boucher's most famous patron.
“We got to talking”—so David Antin begins the introduction to Radical Coherency, embarking on the pursuit that has marked much of his breathless, brilliantly conversational work. For the past forty years, whether spoken under the guise of performance artist or poet, cultural explorer or literary critic, Antin’s innovative observations have helped us to better understand everything from Pop to Postmodernism. Intimately wedded to the worlds of conceptual art and poetics, Radical Coherency collects Antin’s influential critical essays and spontaneous, performed lectures (or “talk pieces”) for the very first time, capturing one of the most distinctive perspectives in contemporary literature. The essays presented here range from the first serious assessment of Andy Warhol published in a major art journal, as well as Antin’s provocative take on Clement Greenberg’s theory of Modernism, to frontline interventions in present debates on poetics and fugitive pieces from the ’60s and ’70s that still sparkle today—and represent a gold mine for art historians of the period. From John Cage to Allan Kaprow, Mark Rothko to Ludwig Wittgenstein, Antin takes the reader on an idiosyncratic, personal journey through twentieth-century culture with his trademark antiformalist panache—one thatwill be welcomed by any fan of this consummate trailblazer.
A video game is half-real: we play by real rules while imagining a fictional world. We win or lose the game in the real world, but we slay a dragon (for example) only in the world of the game. In this thought-provoking study, Jesper Juul examines the constantly evolving tension between rules and fiction in video games. Discussing games from Pong to The Legend of Zelda, from chess to Grand Theft Auto, he shows how video games are both a departure from and a development of traditional non-electronic games. The book combines perspectives from such fields as literary and film theory, computer science, psychology, economic game theory, and game studies, to outline a theory of what video games are, how they work with the player, how they have developed historically, and why they are fun to play.Locating video games in a history of games that goes back to Ancient Egypt, Juul argues that there is a basic affinity between games and computers. Just as the printing press and the cinema have promoted and enabled new kinds of storytelling, computers work as enablers of games, letting us play old games in new ways and allowing for new kinds of games that would not have been possible before computers. Juul presents a classic game model, which describes the traditional construction of games and points to possible future developments. He examines how rules provide challenges, learning, and enjoyment for players, and how a game cues the player into imagining its fictional world. Juul's lively style and eclectic deployment of sources will make Half-Real of interest to media, literature, and game scholars as well as to game professionals and gamers.
