LOPSTR'13

23rd International Symposium on Logic-Based Program Synthesis and Transformation LOPSTR 2013

http://www.utdallas.edu/~gupta/lopstr Madrid, Spain, September 18-20, 2013

DEADLINE: Paper submission: June 24, 2013

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

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 23rd International Symposium on Logic-based Program Synthesis and Transformation (LOPSTR 2013) will be held in Madrid, Spain; previous symposia were held in Leuven, Hagenberg, Coimbra, Valencia, Lyngby, Venice, London, Verona, Uppsala, Madrid, Paphos, London, Venice, Manchester, Leuven, Stockholm, Arnhem, Pisa, Louvain-la-Neuve, Manchester and Odense (you might have a look at the contents of past LOPSTR symposia). LOPSTR 2013 will be co-located with PPDP 2013 (International ACM SIGPLAN Symposium on Principles and Practice of Declarative Programming).

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. Both full papers and extended abstracts 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 * verification * analysis * specialization * composition * certification * transformational techniques in SE * synthesis * transformation * optimisation * inversion * program/model manipulation * security * 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, conference, or workshop with refereed proceedings. Work that already appeared in unpublished or informally published workshop proceedings may be submitted (please contact the PC chair in case of questions). Proceedings

The formal post-conference proceedings will be published by Springer in the Lecture Notes in Computer Science series.

Important Dates

Paper submission: June 24, 2013 Notification (for pre-proceedings): July 24, 2013 Camera-ready (for pre-proceedings): August 5, 2013 Symposium: September 18-20, 2013

Submissions must be formatted in the Lecture Notes in Computer Science style. They cannot exceed 15 pages including references but excluding well-marked appendices not intended for publication. Referees are not required to read the appendices, and thus papers should be intelligible without them.

Full papers can be directly accepted for publication in the formal proceedings to be published by Springer in the LNCS series or accepted only for presentation at the symposium. After the symposium, all authors of extended abstracts and full papers accepted only for presentation 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 may also be published in the formal proceedings.

Authors should submit an electronic copy of the paper (written in English) in PDF or Postscript (Level 2). Each submission must include on its first page the paper title; authors and their affiliations; contact author's email; abstract; and three to four keywords. The keywords will be used to assist us in selecting appropriate reviewers for the paper. If electronic submission is impossible, please contact the program chair for information on how to submit hard copies.

Papers should be submitted to the submission website for LOPSTR 2013.
