LOPSTR 2004 Verona, Italy, August 26-28, 2004 http://www.sci.univr.it/~lopstr04 CALL FOR PAPERS ***EXTENDED DEADLINE*** The aim of the LOPSTR series is to stimulate and promote international research and collaboration on logic-based program development, and the workshop is open to contributions in logic-based program development in any language paradigm. Starting this year, LOPSTR will put extra emphasis to the field of verification; in fact LOPSTR will also incorporate the VCL (verification in computational logic) workshop series. LOPSTR'04 will be held at the University of Verona http://www.univr.it co-located with SAS 2004 http://www.sci.univr.it/~sas04, the International Static Analysis Symposium, PEPM 2004 http://www.sci.univr.it/~pepm04 - ACM SIGPLAN 2004 Workshop on Partial Evaluation and Semantics Based Program Manipulation, and PPDP 2004 http://www.sci.univr.it/~ppdp04 - 6th ACM-SIGPLAN International Conference on Principles and Practice of Declarative Programming. Past workshops were held in Manchester, UK (1991, 1992, 1998), Louvain-la-Neuve, Belgium (1993), Pisa, Italy (1994), Arnhem, the Netherlands (1995), Stockholm, Sweden (1996), Leuven, Belgium (1997), Venice, Italy (1999), London, UK (2000), Paphos, Cyprus (2001), Madrid, Spain (2002), Uppsala, Sweden (2003). Since 1994 the proceedings have been published in the LNCS series of Springer-Verlag. LOPSTR also aims to be a lively, friendly forum for presenting and discussing work in progress, so it is a real workshop in the sense that it is also intended to provide useful feedback to authors on their preliminary research. Formal proceedings of the workshop are produced only after the workshop, so that authors can incorporate this feedback in the published papers. Scope of the Workshop We solicit extended abstracts and full papers. Topics of interest cover all aspects of logic-based program development, all stages of the software life cycle, and issues of both programming-in-the-small and programming-in-the-large. The following is a non-exhaustive list of topics: * specification * synthesis * verification * transformation * specialisation * analysis * optimisation * composition * reuse * applications and tools * proofs as programs * component-based software development * agent-based software development * software architectures * design patterns and frameworks * program refinement and logics for refinement Submission Guidelines Authors can either submit extended abstracts (short papers) describing work in progress or they can choose to submit full papers. Contributions should be written in English and should be submitted electronically in Postscript or PDF format at http://profs.sci.univr.it/~lopstr04/index.html. Authors are also asked to send the title and abstract of their submission three days before the deadline to lopstr04@sci.univr.it. Prospective authors who have difficulties for the electronic submission may contact the chairman at lopstr04@sci.univr.it. Extended abstracts should not exceed 6 pages in llncs format and may describe work in progress. Promising abstracts relevant to the scope of LOPSTR will be selected for presentation at the workshop. The submission deadline for extended abstract is May 17, 2004 (extended, strict). Full papers should not exceed 16 pages (including references) in llncs format. These papers will be judged using ordinary conference quality criteria and accepted papers will have to be presented at the workshop and will automatically appear in the pre-proceedings as well as in the final collection of papers, published in the LNCS series. The submission deadline for full papers is May 7, 2004 (extended, strict). Accepted papers and abstracts will be collected in informal pre-proceedings which will be available at the workshop. After the workshop, authors of extended abstract which are judged mature for publication will be invited to submit full papers. These will be reviewed according to the usual refereeing procedures, and accepted papers will be published in the final collection of papers (together with the accepted full papers) which is expected to be published in the Lecture Notes in Computer Science series by Springer-Verlag. All the full papers accepted before the workshop will automatically appear in that book as well; there will be no additional refereeing (although authors will be given a chance to revise their paper, if they so wish, based upon the feedback from the LOPSTR event).
