========================================================= WLP 2019: Call for Papers ========================================================= 33rd Workshop on (Constraint) Logic Programming Cottbus, Germany, September 9-13, 2019 (part of Declare 2019; co-located with INAP, WFLP, and QPLogic) Important Dates Abstract submission: May 27, 2019 Paper submission: June 3, 2019 Notification of acceptance: July 1, 2019 Camera-ready papers: July 29, 2019 Early registration: August 12, 2019 Online Registration: September 2, 2019 Workshop: September 9-13, 2019 WLP 2019 The workshops on (constraint) logic programming serve as the scientific forum of the annual meeting of the Society of Logic Programming (GLP, Gesellschaft fuer Logische Programmierung e.V.). They bring together researchers (not only from Germany) interested in logic programming, constraint programming, and related areas like databases, artificial intelligence, and operations research. Previous workshops have been held in Germany, Austria, Switzerland, Egypt, Japan, Denmark, Spain, Brazil, Italy, and France. Contributions are welcome on all theoretical, experimental, and application aspects of logic and constraint logic programming. The topics include, but are not limited to the following areas: + Logic and Constraint Logic Programming Languages and Extensions + Knowledge Representation and Non-monotonic Reasoning + Applications and Application Areas of (C)LP + Implementations WLP 2019 will be part of DECLARE 2019 and hence be co-located with INAP 2019 (International Conference on Applications of Declarative Programming and Knowledge Management), WFLP 2019 (International Workshop on Functional and Logic Programming), and QPLogic 2019 (Quantum and Probability Logic). Submission Guidelines Authors are invited to submit long papers (no longer than 15 pages) or short papers (no longer than 6 pages) in the following categories: + Regular research papers + Application papers + System descriptions We also encourage submissions on ongoing work of PhD students (no longer than 6 pages). Submissions must be unpublished original work and not submitted for publication elsewhere. However, work that already appeared in informally published workshop proceedings may be submitted too. All papers will be judged on the basis of significance, relevance, correctness, originality, and clarity. All submissions must be formatted in the Lecture Notes in Computer Science style. For further information on the submission procedure, please, visit the conference web site: declare19.de Proceedings All papers accepted for presentation at the conference will be published in informal proceedings publicly available at the Computing Research Repository. According to the program committee reviews, submissions can be directly accepted for publication in the formal post-conference proceedings. The formal post-conference proceedings will be published in both electronic and paper formats by Springer in the Lecture Notes in Computer Science series. After the conference, all authors accepted only for presentation will be invited to revise and/or extend their submissions in the light of the feedback solicited at the conference. Then, after another round of reviewing, these revised papers may also be published in the formal proceedings. All accepted papers will be presented during the conference. At least one author of an accepted contribution is expected to register for the conference and present the paper.
