---------------------------------------- Apologies if you receive multiple copies ________________________________________ Second Call for Papers ------------------------------------------------------------ Third Workshop on Constraint Handling Rules CHR 2006 July 9, 2006 S. Servolo, Venice, Italy Co-located with the International Colloquium on Automata, Languages and Programming (ICALP 2006) ------------------------------------------------------------ http://www.cs.kuleuven.be/~toms/CHR2006/ Introduction ------------ The Constraint Handling Rules (CHR) language has become a major declarative specification and implementation language for constraint reasoning algorithms and applications. Algorithms are often specified using inference rules, rewrite rules, sequents, proof rules or logical axioms that can be directly written in CHR. Its clean semantics facilitates program design, analysis and transformation. See the CHR website (http://www.cs.kuleuven.be/~dtai/projects/CHR/) for more information. Previous Workshops on Constraint Handling Rules were organized in May 2004 in Ulm (Germany) and in October 2005 in Sitges (Spain). Topics of Interest ------------------ The workshop calls for full papers and short papers describing ongoing work, on all aspects of CHR, including topics such as: - (Logical) Algorithms - Applications - Comparisons with Related Approaches - Constraint Solvers - Critical Assessment - Expressivity and Complexity - Implementations and Optimization - Language Extensions (Types, Modules) - Program Analysis - Program Transformation and Generation - Programming Environments (Debugging) - Programming Pearls - Retractable Constraints - Semantics Awards ------ The best paper receives the CHR Best Paper Award. It is chosen among all submissions for its outstanding quality in both presentation and scientific contribution and for its impact on the field of CHR. Submission Information ---------------------- All papers must be written in English and not exceed 15 pages in Springer LNCS format. The authors are encouraged, although not obliged, to submit their papers already in Springer LNCS format. General information about the Springer LNCS series and the LNCS authors' instructions are available at the Springer LNCS/LNAI home page. Submissions should be sent to chrworkshop@gmail.com and mention 'CHR 2006 Submission' in the subject. Every submission should include the names and e-mail addresses of the authors (with the corresponding author indicated), the paper abstract in ASCII format and the actual paper in postscript or PDF format. The submission should also indicate whether it is a full paper or a short paper. Accepted papers will be published in a technical report.
