The Arti?cial Evolution conference was originally conceived as a forum for the French-speaking Evolutionary Computation community, but has of late been acquiring an European audience, with several papers from Germany, Austria, Italy, Spain... However, AE remains as intended a small and friendly gathering, which will continue to be held every two years. Previous AE meets were held in Toulouse, Brest, and Nˆ ?mes. This year, the hosting was done by the LIL (Laboratoire d’Informatique du Littoral) in the not-so-cold city of Dunkerque. The invited talk on “Fitness Landscapes and Evolutionary Algorithms” was delivered by Colin Reeves of Coventry University This volume contains a selection of the papers presented at the conference. Twenty-seven papers were presented orally at the conference, selected from over 40 papers refereed by the program committee. After the conference, each p- sentation was reviewed and 20 papers were retained and revised for publication in this volume. The papers in this volume have been grouped into the following ?ve sections which more or less re?ect the organization of the oral presentations. 1. Invited Paper: C. Reeves brightly describes the state of the art in Fitness Landscapes.

This book is devoted to the investigation of a special topic in theoretical computer science - communication complexity as an abstract measure of the complexity of computing problems. Its main aim is to show how the theoretical study of communication complexity can be useful in the process of designing effective parallel algorithms. The author shows how to get important information about the parallel complexity (parallel time, the number of processors, the descriptional complexity of the topology of the parallel architecture) of specific computing problems from knowledge of their communication complexity. The book is written as a textbook for undergraduate and graduate students and provides a careful explanation of the subject as well as motivation for further research.

JavaScript is a powerful, object-based scripting language; JavaScript programs can be embedded directly into HTML web pages. When combined with the Document Object Model (DOM) defined by a web browser, JavaScript allows you to create Dynamic HTML (DHTML) content and interactive client-side web applications. JavaScript syntax is based on the popular programming languages C, C++, and Java, which makes it familiar and easy to learn for experienced programmers. At the same time, JavaScript is an interpreted scripting language, providing a flexible, forgiving environment in which new programmers can learn. *JavaScript: The Definitive Guide* provides a thorough description of the core JavaScript language and both the legacy and standard DOMs implemented in web browsers. The book includes sophisticated examples that show you how to handle common tasks such as validating form data, working with cookies, and creating portable DHTML animations. The book also contains detailed reference sections that cover the core JavaScript API, the legacy client-side API, and the W3C standard DOM API, documenting every JavaScript object, method, property, constructor, constant, function, and event handler in those APIs. This fourth edition of the bestselling JavaScript book has been carefully updated to cover JavaScript 1.5 (ECMAScript Version 3). The book also provides complete coverage of the W3C DOM standard (Level 1 and Level 2), while retaining material on the legacy Level 0 DOM for backward compatibility. *JavaScript: The Definitive Guide* is a complete programmer's guide and reference manual for JavaScript. It is particularly useful for developers working with the latest standards-compliant web browsers, such as Internet Explorer 6, Netscape 6, and Mozilla. HTML authors can learn how to use JavaScript to build dynamic web pages. Experienced programmers can quickly find the information they need to start writing sophisticated JavaScript programs. This book is an indispensable reference for all JavaScript programmers, regardless of experience level. *Description from the Fourth Edition (2007, O'Reilly Media)* <h2>Printing History</h2> <dl> <dt>August 1996</dt> <dd>Beta Edition.</dd> <dt>January 1997</dt> <dd>Second Edition.</dd> <dt>June 1998</dt> <dd>Third Edition.</dd> <dt>January 2002</dt> <dd>Fourth Edition.</dd> </dl>

More and more, software systems involve autonomous and distributed software components that have to execute and interact in open and dynamic environments, such as in pervasive, autonomous, and mobile applications. The requirements with respect to dynamics, openness, scalability, and decentralization call for new approaches to software design and development, capable of supporting spontaneous configuration, tolerating partial failures, or arranging adaptive reorganization of the whole system. Inspired by the behaviour of complex natural systems, scientists and engineers have started to adjust their mechanisms and techniques for self-organization and adaption to changing environments. In line with these considerations, Mamei and Zambonelli propose an interaction model inspired by the way masses and particles in our universe move and self-organize according to contextual information represented by gravitational and electromagnetic fields. The key idea is to have the components’ actions driven by computational force fields, generated by the components themselves or by some infrastructures, and propagated across the environment. Together with its supporting middleware infrastructure – available with additional information under – this model can serve as the basis for a general purpose and widely applicable approach for the design and development of adaptive distributed applications.
