TABLEAUX 2021

General Information

The 30^th International Conference on Automated Reasoning with Analytic Tableaux and Related Methods (TABLEAUX 2021) will be hosted by the University of Birmingham, UK, 6-9 September 2021.

TABLEAUX is the main international conference at which research on all aspects -- theoretical foundations, implementation techniques, systems development and applications -- of tableaux-based reasoning and related methods is presented. The first TABLEAUX conference was held in Lautenbach near Karlsruhe, Germany, in 1992. Since then it has been organised on an annual basis (sometimes as a part of IJCAR).

TABLEAUX 2021 will be co-located with the 13^th International Symposium on Frontiers of Combining Systems (FroCoS 2021). The conferences will provide a rich programme of workshops, tutorials, invited talks, paper presentations and system descriptions.

Scope of conference

Tableaux and other proof based methods offer convenient and flexible tools for automated reasoning for both classical and non-classical logics. 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, linear, substructural, relevance, non-monotonic logics) and their proof-theoretic foundations;
• related methods (SMT, model elimination, model checking, connection methods, resolution, BDDs, translation approaches);
• sequent, natural deduction, labelled, nested and deep 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 TABLEAUX community and should focus on the role of reasoning, and logical aspects of the solution.

Invited Speakers

TABLEAUX 2021 is pleased to confirm the following invited speakers:

Orna Kupferman (Hebrew University, Israel).
Revantha Ramanayake (University of Gröningen, The Netherlands).
Greg Restall (University of Melbourne, Australia / University of St Andrews, UK).
Renate Schmidt (University of Manchester, UK). Joint with FroCoS.

Submission Guidelines

Submissions are invited in two categories:

• research papers, which describe original theoretical research or applications, with length up to 15 pages excluding references;
• system descriptions, with length up to 9 pages excluding references.

There will also be a later call inviting position papers and brief reports on work-in-progress. Details will be kept up to date on the website.

Submissions will be reviewed by the PC, possibly with the help of external reviewers, taking into account readability, relevance and originality. Any additional material (going beyond the page limit) can be included in a clearly marked appendix, which will be read at the discretion of the committee and must be removed for the camera-ready version.

For category (A) submissions, the reported results must be original and not submitted for publication elsewhere. For category (B) submissions, a working implementation must be accessible via the internet. Authors are encouraged to publish the implementation under an open source license. The aim of a system description is to make the system available in such a way that people can use it, understand it, and build on it. Accepted papers in categories (A) and (B) 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=tableaux21.

For all accepted papers at least one author is required to register to the conference and present the paper. A title and a short abstract of about 100 words must be submitted before the paper submission deadline. Formatting instructions and the LNCS style files can be obtained at:
http://www.springer.com/br/computer-science/lncs/conference-proceedings-guidelines.

Important Dates

• Abstract submission: 19 April 2021 26 April 2021 AoE (extended)
• Paper submission: 26 April 2021 30 April 2021 AoE (extended)
• Notification: 14 June 2021
• Conference: 6-9 September 2021

Conference Format and COVID-19

TABLEAUX 2021 and FroCoS 2021 are intended to be hybrid conferences welcoming both physical and virtual participation. The organisers are closely monitoring the pandemic situation and may choose to make the conference virtual-only if it seems unreasonable to host any sort of physical event. A final decision will be taken before the notification date 14 June (12 weeks before the conference) to leave ample time for potential travel plans to be made.

Best Paper Awards

The program committee will select:

• the TABLEAUX 2021 Best Paper; and
• the TABLEAUX 2021 Best Paper by a Junior Researcher.

Researchers will be considered "junior" if either they are students or their PhD degree date is less than two years from the first day of the meeting. The two awards will be presented at the conference.

Travel Grants for Students

Some funding may be available to support students participating at TABLEAUX 2021. More details will appear here in due time.

Workshops and Tutorials

In keeping with the tradition of TABLEAUX and FroCoS, we invite proposals for colocated workshops and tutorials on all topics related to logical reasoning: from theoretical aspects, to applications, to tools for interactive or automated reasoning. Workshops and tutorials can target the logical systems community in general, or alternatively focus on a particular system, recent theoretical development or application.

If in-person participation is possible, colocated events should take place on 6 and 8 September 2021. Workshop/tutorial-only attendees will enjoy a significantly reduced registration fee. Detailed matters such as the paper submission and review process, or the publication of proceedings, are up to the organisers of individual events. All accepted workshops and tutorials will be expected to have their program ready by 10 August 2021.

Proposals are invited to be submitted by email to frocos2021@easychair.org and tableaux21@easychair.org. no later than 19 April 2021. Selected events will be notified by 26 April 2021. The workshop/tutorial selection committee consists of the FroCoS and TABLEAUX program chairs.

Tutorials. We expect tutorials to be delivered in hybrid mode, combining the use of pre-recorded lecture material and (online or face-to-face) synchronous sessions. Proposals for tutorials should contain at least the following pieces of information:

• name and contact details of the main organiser(s)
• (if applicable) names of additional organisers
• title of the tutorial
• estimated number of attendees
• short description of topic (up to one page)

Workshops. Proposals for workshops should contain at least the following pieces of information:

• name and contact details of the main organiser(s)
• (if applicable) names of additional organisers
• title and organisational style of event (public workshop, project workshop, etc.)
• preferred workshop mode (hybrid, situation permitting, or fully online)
• estimated number of attendees
• short description of topic (up to one page)
• (if applicable) pointers to previous editions of the workshop, or to similar events
