                 International Symposium on 
       Logic-based Program Synthesis and Transformation,
                      LOPSTR'03
            August 25 - 27, 2003 Uppsala, Sweden

                      CALL FOR PAPERS

-----------------------------------------------------------

The aim of the LOPSTR series is to stimulate and promote international
research and collaboration on logic-based program development, and the
symposium is open to contributions in logic-based program development
in any language paradigm.  

LOPSTR 2003 will be held at the University of Uppsala, as part
of PLI 2003 (Principles, Logics, and Implementation of High-Level 
Programming Languages), a confederation of conferences and workshops
including ICFP 2003 (ACM-SIGPLAN International Conference on
Functional Programming) and PPDP 2003 (ACM-SIGPLAN International
Conference on Principles and Practice of Declarative Programming).

Past events 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).  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 has a strong workshop character, in
the sense that it is also intended to provide useful feedback to
authors on their preliminary research. Formal proceedings of the
symposium are produced only after the symposium, so that authors can
incorporate this feedback in the published papers.


Scope of the Workshop

We solicit full papers as well as extended abstracts describing work
in progress. 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
 *    composition
 *    reuse
 *    optimisation
 *    applications and tools
 *    component-based software development
 *    agent-based software development
 *    software architectures
 *    design patterns and frameworks
 *    program refinement and logics for refinement
 *    proofs as programs


Submission Guidelines

Authors can either submit extended abstracts (up to 6 pages)
describing work in progress or they can choose to submit full papers
(up to 16 pages in llncs format).
 
Contributions should be written in English and should be submitted
electronically in Postscript or PDF format to the program chairman at
the following email address: Maurice.Bruynooghe at cs.kuleuven.ac.be.
Prospective authors who have difficulties for the electronic
submission may contact the chairman. Accepted papers have to be
presented at the Symposium by one of the authors and will appear in
the  informal pre-proceedings distributed at the Symposium.
 

Formal Proceedings

After the workshop, authors of work that is judged mature for
publication will be invited to submit a full paper. These will be
reviewed according to the usual refereeing procedures, and accepted
papers will be published in a final collection of papers which are
expected to be published in the Lecture Notes in Computer Science
series by Springer-Verlag.

Accepted full papers that the PC considers of sufficient quality will
be exempted from a second reviewing round.
