------------------------------------------------------------------------------------------- SECOND CALL FOR PAPERS

TABLEAUX 2017 26th International Conference on Automated Reasoning with Analytic Tableaux and Related Methods University of Brasilia, Brazil September 25-28, 2017

Submission Deadline: 25 Apr 2017

http://tableaux2017.cic.unb.br/

GENERAL INFORMATION TABLEAUX is the main international conference at which research on all aspects, theoretical foundations, implementation techniques, systems development and applications, of the mechanization of tableau-based reasoning and related methods is presented. As the first TABLEAUX workshop was held in Lautenbach in 1992, this year's conference will include special events celebrating 25 years of TABLEAUX.

The conference will be held in Brasilia from 25-28 September 2017. It will be co-located with both the 11th International Symposium on Frontiers of Combining Systems (FroCoS 2017) and the 8th International Conference on Interactive Theorem Proving (ITP 2017).

TOPICS Tableau methods offer a convenient and flexible set of tools for automated reasoning in classical logic, extensions of classical logic, and a large number of non-classical logics. For large groups of logics, tableau methods can be generated automatically. Areas of application include verification of software and computer systems, deductive databases, knowledge representation and its required inference engines, teaching, and system diagnosis.

Topics of interest include but are not limited to:

* tableau methods for classical and non-classical logics (including first-order, higher-order, modal, temporal, description, hybrid, intuitionistic, substructural, relevance, non-monotonic logics) and their proof-theoretic foundations; * related methods (SMT, model elimination, model checking, connection methods, resolution, BDDs, translation approaches); * sequent calculi and natural deduction calculi for classical and non-classical logics, as tools for proof search and proof representation; * flexible, easily extendable, light weight methods for theorem proving; * novel types of calculi for theorem proving and verification in classical and non-classical logics; * systems, tools, implementations, empirical evaluations and applications (provers, logical frameworks, model checkers, ...); * implementation techniques (data structures, efficient algorithms, performance measurement, extensibility, ...); * extensions of tableau procedures with conflict-driven learning, generation of proofs; compact (or humanly readable) representation of proofs; * decision procedures, theoretically optimal procedures; * applications of automated deduction to mathematics, software development, verification, deductive and temporal databases, knowledge representation, ontologies, fault diagnosis or teaching.

We also welcome papers describing applications of tableau procedures to real world examples. Such papers should be tailored to the tableau community and should focus on the role of reasoning, and logical aspects of the solution.

CELEBRATING 25 YEARS To celebrate 25 years TABLEAUX the conference will include a special session of invited talks by:

Reiner Haehnle Technische Universitaet Darmstadt, Germany Wolfgang Bibel Technische Universitaet Darmstadt, Germany

Details will be published in separate calls and on the conference website.

PUBLICATION DETAILS The conference proceedings will be published in the Springer LNAI/LNCS series, as in previous editions.

SUBMISSIONS Submissions are invited in two categories:

A Research papers, which describe original theoretical research, original algorithms, or applications, with length up to 15 pages. B System descriptions, with length up to 9 pages.

Submissions will be reviewed by the PC, possibly with the help of external reviewers, taking into account readability, relevance and originality.

For category A, theoretical results and algorithms must be original, and not submitted for publication elsewhere. Submissions will be reviewed taking into account correctness, theoretical elegance, and possible implementability.

For category B submissions, a working implementation must be accessible via the internet, which includes sources. The aim of a system description is to make the system available in such a way that users can use it, understand it, and build on it.

Accepted papers in both categories will be published in the conference proceedings. Papers must be edited in LaTeX using the llncs style and must be submitted electronically as PDF files via the EasyChair system: https://easychair.org/conferences/?conf=3Dtableaux2017.

For all accepted papers at least one author is required to attend the conference and present the paper. A paper title and a short abstract of about 100 words must be submitted before the paper submission deadline. Further information about paper submissions will be made available at the conference website. Be aware that neither plagiarism, nor self-plagiarism, nor duplicate publication is acceptable. Formatting instructions and the LNCS style files can be obtained via

BEST PAPER AWARD The TABLEAUX 2017 Best Paper Award will be presented to the best submission nominated and chosen by the Program Committee among the accepted papers. The eligibility criteria will place emphasis on the originality and significance of the contribution, but readability and the overall technical quality, including correctness and completeness of results, will also be considered. The TABLEAUX Best Paper Award was established in 2015 and is a permanent initiative of TABLEAUX.
