Constraints have emerged as the basis of a representational and computational paradigm that draws from many disciplines and can be brought to bear on many problem domains. This volume contains papers dealing with all aspects of c- puting with constraints. In particular, there are several papers on applications of constraints, re?ecting the practical usefulness of constraint programming. The papers were presented at the 1998 International Conference on Principles and Practice of Constraint Programming (CP 98), held in Pisa, Italy, 26{30 - tober, 1998. It is the fourth in this series of...

Thecircleisclosed.The European Modula-2 Conference was originally launched with the goal of increasing the popularity of Modula-2, a programming language created by Niklaus Wirth and his team at ETH Zuric ] h as a successor of Pascal. For more than a decade, the conference has wandered through Europe, passing Bled, Slovenia, in1987, Loughborough, UK, in1990, Ulm, Germany, in1994, and Linz, Austria, in 1997. Now, at the beginning of the new millennium, it is back at its roots in Zuric ] h, Switzerland. While traveling through space and time, the conference has mutated. It has widened its scope...

CICLing 2003 (www.CICLing.org) was the 4th annual Conference on Intelligent Text Processing and Computational Linguistics. It was intended to provide a balanced view of the cutting-edge developments in both the theoretical foundations of computational linguistics and the practice of natural language text processing with its numerous applications. A feature of CICLing conferences is their wide scope that covers nearly all areas of computational linguistics and all aspects of natural language processing applications. The conference is a forum for dialogue between the specialists working in...

This volume, Petri Net Technology for Communication-Based Systems, is a state-of-the-artreportin the seriesAdvances in Petri Nets. It showshowvarious well-established and new Petri net notions and techniques can be used for m- elingcommunication-basedsystems, withspecialfocusonwork?owmanagement and business processes. In the last 6 years this topic has been studied by the DFG Forschergruppe Petri Net Technology in Berlin in close cooperation with the international c- munity. The main results of this cooperation were presented at the 1st and 2nd...

The 11th International Symposium on Graph Drawing (GD 2003) was held on September 21 24, 2003, at the Universit a degli Studi di Perugia, Perugia, Italy. GD 2003 attracted 93 participants from academic and industrial institutions in 17 countries. In response to the call for papers, the program committee received 88 re- larsubmissionsdescribingoriginalresearchand/orsystemdemonstrations.Each submission was reviewed by at least 4 program committee members and c- ments were returned to the authors. Following extensive e-mail discussions, the program committee accepted 34 long papers (12 pages...

This book is devoted to the 6th International Conference on Theory and - plications of Satis?ability Testing (SAT 2003) held in Santa Margherita Ligure (Genoa, Italy), during May5 8,2003. SAT 2003followedthe WorkshopsonS- is?ability held in Siena (1996), Paderborn (1998), and Renesse (2000), and the Workshop on Theory and Applications of Satis?ability Testing held in Boston (2001) and in Cincinnati (2002). As in the last edition, the SAT event hosted a SAT solvers competition, and, starting from the 2003 edition, also a Quanti?ed Boolean Formulas (QBFs) solvers comparative evaluation. There...

The Workshop on Approximation and Online Algorithms (WAOA 2003) focused on the design and analysis of algorithms for online and computationally hard problems. Both kinds of problems have a large number of applications ar- ing from a variety of ?elds. The workshop also covered experimental research on approximation and online algorithms. WAOA 2003 took place in Budapest, Hungary, from September 16 to September 18. The workshop was part of the ALGO 2003 event, which also hosted ESA 2003, WABI 2003, and ATMOS 2003. TopicsofinterestforWAOA2003were: competitiveanalysis, inapproximab- ityresults,...
