LOPSTR 2001 

Eleventh International Workshop on
Logic-based Program Synthesis and Transformation

November 28 - 30, 2001

Paphos, Cyprus
LOPSTR 2001 is co-located with the 17th International Conference on Logic Programming (ICLP 2001) and the  7th International  Conference on Principle and Practice of  Constraint Programming (CP 2001). Joint events and reduced joint registration are planned.
The aim of the LOPSTR  workshops 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. 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).

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 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
  • optimisation
  • composition
  • reuse
  • applications
  • component-based software development
  • software architectures
  • design patterns and frameworks

Submission Guidelines

  • Authors should submit extended abstracts describing work in progress. Extended abstracts should be written in English and should not exceed 8 pages in llncs format. Abstracts should be submitted electronically in Postscript format to the program chairman at the following email address: adp@iasi.rm.cnr.it.  The submission deadline is September 24, 2001.
  • Promising abstracts relevant to the scope of LOPSTR will be selected for presentation at the workshop. The notification of acceptance or rejection will be sent by October 5, 2001. Accepted abstracts will be collected in informal pre-proceedings which will be available at the workshop. Perspective authors who have difficulties for the electronic submission may contact the chairman.
  • After the workshop, authors of work which is 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 formal proceedings of the workshop which will be published in the Lecture Notes in Computer Science series by Springer-Verlag.
