============================================================

Objectives:

The aim of the LOPSTR series is to stimulate and promote international research and collaboration on logic-based program development. LOPSTR is open to contributions in logic-based program development in any language paradigm. LOPSTR has a reputation for being a lively, friendly forum for presenting and discussing work in progress. Formal proceedings are produced only after the symposium so that authors can incorporate this feedback in the published papers.

The 21st International Symposium on Logic-based Program Synthesis and Transformation (LOPSTR 2011) will be held in Odense, Denmark; previous symposia were held in Hagenberg, Coimbra, Valencia, Lyngby, Venice, London, Verona, Uppsala, Madrid, Paphos, London, Venice, Manchester, Leuven, Stockholm, Arnhem, Pisa, Louvain-la-Neuve, and Manchester (you might have a look at the contents of past LOPSTR symposia). LOPSTR
2011 will be co-located with PPDP 2011 (International ACM SIGPLAN Symposium on Principles and Practice of Declarative Programming).


Topics:

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. Papers describing applications in these areas are especially welcome. Contributions are welcome on all aspects of logic-based program development, including, but not limited to:

- specification
- synthesis
- verification
- transformation
- analysis
- optimisation
- specialization
- partial evaluation
- inversion
- composition
- program/model manipulation
- certification
- security
- transformational techniques in SE
- applications and tools

Survey papers, that present some aspect of the above topics from a new perspective, and application  papers, that describe experience with industrial applications, are also welcome. Papers must describe original work, be written and presented  in English, and must not substantially overlap with papers that have been published or that are simultaneously submitted to a journal or a conference with refereed proceedings. Work that already appeared in unpublished or informally published workshops proceedings may be submitted.

Following past editions, the formal post-conference proceedings will be published by Springer in the Lecture Notes in Computer Science (LNCS) series.


IMPORTANT DATES AND SUBMISSION GUIDELINES:

- Paper submission: March 27,  2011
- Extended abstract submission: April 3, 2011
- Notification (for pre-proceedings): May 16, 2011
- Camera-ready (for pre-proceedings): June 12, 2011
- Symposium: July 18-20, 2011


Submissions can either be (short) extended abstracts or (full) papers whose length should not exceed 9 and 15 pages (including references), respectively. Submissions must be formatted in the Lecture Notes in Computer Science style (excluding well-marked appendices not intended for publication). Referees are not required to read the appendices, and thus papers should be intelligible without them. Short papers may describe work-in-progress or tool demonstrations.

Both short and full papers can be accepted for presentation at the symposium and will then appear in the LOPSTR 2011 pre-proceedings. Full papers can also be immediately accepted for publication in the formal proceedings to be published by Springer in the LNCS series. In addition, after the symposium, the programme committee will select further short or full papers presented in LOPSTR 2011 to be considered for formal publication. These authors will be invited to revise and/or extend their submissions in the light of the feedback solicited at the symposium. Then after another round of reviewing, these revised papers can also be published in the formal proceedings.
