30th International Conference on Automated Reasoning with Analytic Tableaux and Related Methods 6-9 September. Birmingham, UK.

General Information

The 30th 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. It will primarily be a virtual conference, due to ongoing conerns about COVID-19. However it will be possible to attend the conference physically for those who are able to travel to Birmingham and take advantage of a hybrid format. More information can be found here.

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 13th 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:

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:

Michael Benedikt (University of Oxford, UK). Joint with FroCoS.
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

The submission deadline has now passed.

Submissions are invited in two categories:

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:

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:

Accepted Papers

We are pleased to announce that the following papers have been selected for presentation at TABLEAUX 2021 and publication in the conference proceedings.

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

Due to ongoing concerns and continued instability caused by COVID-19, TABLEAUX 2021 will take place primarily as a virtual conference. For those who are easily able to travel to Birmingham, there will be a video-conferencing room available at the School of Computer Science for hybrid participation. Delegates should indicate their intention to take advantage of this during registration. Depending on the level of interest, there may be further physical elements included for those who participate physically, e.g. social, scientific and networking events.


The conference proceedings will be published in the Springer series Lecture Notes in Artificial Intelligence (LNAI/LNCS).

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.

Workshops and Tutorials

We are pleased to announce that TABLEAUX and FroCoS will host two one workshops during the conference week.

Trends in Arithmetic Theories. (Organised by Dmitry Chistikov and Chistophe Haase). Logical theories of arithmetic play an important role in a variety of different areas of computer science and have been studied since the early days of the field. The recent years have seen a lot of progress on all aspects of such theories, ranging from new foundational results over more performant decision procedures to novel application domains. This progress has largely been obtained independently without much interaction between researchers working on different aspects of this field. The goal of this workshop is to bring together researchers working in the field to exchange latest trends, understand currently existing challenges and to potentially initiate new collaborations. The organisation of the workshop will be supported by the ERC Starting Grant ARiAT.

Automated Reasoning in Quantified Non-Classical Logics (ARQNL 2021). (Webpage. Organised by Christoph Benzmüller and Jens Otten). (This workshop has been cancelled).


TABLEAUX and FroCoS will be entirely free-of-charge to attend, but registration is mandatory to fully engage with the scientific program. We may choose to also stream talks publicly (with no need for registration), but this will be confirmed at a later date.

The registration form is here.

If you wish to attend physically, you should indicate it and submit your registration form by 13 August at the latest. Note that you are able to edit this response in case of change of circumstances. Depending on the level of interest, we may ask for more information or confirmation of physical attendance at a later point. More information about the conference format will be updated here.
