Call for papers International Symposium on Logic-Based Program Synthesis and Transformation LOPSTR 2007 22-24 August 2007, Kongens Lyngby, Denmark (co-located with SAS 2007) url: http://www.cs.kent.ac.uk/events/conf/2007/lopstr/ email: lopstr-2007@kent.ac.uk 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 authors can incorporate this feedback in the published papers. 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 composition security reuse applications and tools component-based software development software architectures agent-based software development program refinement 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. Submission information and Special Issue: Submissions can either be (short) extended abstracts or (full) papers whose length should not exceed 9 and 15 pages respectively. Submissions must be formatted in the Lecture Notes in Computer Science style (excluding bibliography and 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 accepted short and full papers will appear in the pre-proceedings. The full papers will automatically appear in the formal proceedings that will be published by Springer-Verlag in the Lecture Notes in Computer Science series. In addition, after the symposium, the programme committee will select those short papers to be considered for formal publication. These authors will be invited to revise and extend their submissions in the light of the feedback solicited at the meeting. Then after another round of reviewing, these revised papers will be also published in the formal proceedings. The very best papers will additionally be invited to submit for a special issue or special track of the journal Higher-Order and Symbolic Computation, provided there are sufficient high-quality submissions. Papers should be submitted either in PostScript or PDF format and they should be interpretable by Ghostscript or Acrobat Reader.
