Symposium on Intelligent and Autonomous Systems (SIAS 2021) Tallinn, Estonia. June 21-23, 2021. <https://www.sscc.fr/SIAS2021/> https://www.sscc.fr/SIAS2021/ in conjunction with " <https://cs.ttu.ee/events/medi2021/> 10th International Conference on Model and Data Engineering (MEDI 2021)" SIAS 2021 CFP The needs of our daily life push forward modern systems to be well connected more user independent, autonomous, and smart. Intelligent and Autonomous Systems (IAS), that support IoT and CPS, facilitate difficult daily tasks in large eras of applications, especially in industry where a large amount of collected data should be efficiently analyzed in order to be optimally exploited. IAS offer a great importance and promising outcomes with a direct impact on a society safety, productivity, and development. The difficulty arises on both sides of either developing new IAS or enhancing the deployed ones with the needed features and capabilities. IAS run on different environments and should follow different standards that make it difficult to ensure IAS requirements. Many solutions were developed in academia and applied by industrial to build a smart and autonomous system. Some of them rely on formal methods and system engineering whereas others look forward on big data and data analysis using mainly artificial intelligence techniques, in addition to other research areas such as networking, security, resiliency, etc. SIAS2021 provides a platform for professionals from academia, government, and industry to discuss how to address the increasing challenges facing IAS.

The conference aims to attract researchers interested in real-time issues in hardware design, performance analysis, real-time software, scheduling, semantics and verification of real-timed, hybrid and probabilistic systems. We particularly encourage submissions concerning applications of real-time systems and on relevant topics in interdisciplinary areas, such as robot motion planning. Typical topics include (but are not limited to): (1) Foundations and Semantics Theoretical foundations of timed systems and languages; comparison between different models (timed automata, timed Petri nets, hybrid automata, timed process algebra, max-plus algebra, probabilistic models). (2) Methods and Tools Techniques, algorithms, data structures, and software tools for analyzing timed systems and resolving temporal constraints (scheduling, worst-case execution time analysis, optimization, model checking, testing, constraint solving, etc.). (3) Applications Adaptation and specialization of timing technology in application domains such as real-time software, hardware circuits, and problems of scheduling in manufacturing and telecommunication. Special Sessions: Control Synthesis and Motion Planning for Cyber-physical and Control Systems There will be a special session on control synthesis and motion planning for cyber-physical and control systems in FORMATS this year. Real-world systems often include physical components, which impose constraints on the time and space evolution of the system, e.g., robots, smart cities, and medical devices. In this session, we are interested in all approaches, including both model-based and data-driven, to analysis and control design for such systems with logical and temporal specifications. We welcome submissions on this topic and in relevant areas. Paper Submission: FORMATS 2021 solicits high-quality papers reporting research results and/or experience reports related to the topics mentioned above.

Their 2021 editions will be hosted by the University of Birmingham, UK, from 6 to 10 September 2021. In keeping with the tradition of the two events, 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. 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 14 June (12 weeks before the conference) to leave ample time for potential travel plans to be made. 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(a)easychair.org <mailto:frocos2021@easychair.org> and tableaux21(a)easychair.org <mailto: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.

VEST'21 Workshop: First Call for Talks
by Ornela Dardha 26 Mar '21

26 Mar '21

********************************************************************* VEST 2021: 2nd Workshop on Verification of Session Types Online on July 12, 2021, co-located with ICALP 2021 https://sites.google.com/view/vest21/home <https://sites.google.com/view/vest21/home> Submission: Monday, 3rd May 2021 Call for Talks ********************************************************************* * Presentation The goal of this workshop is to bring together researchers and build and strengthen a community working on verification of session types using various theorem provers such as Agda, Coq, Isabelle or any other. Session types are abstract representations of the sequences of operations that computational entities (such as channels or objects) must perform. Stateful entities offer services in a non-uniform way (one cannot pop from an empty stack); traditional type systems cannot guarantee that operations are only invoked when the entity is in the right state. Large-scale software systems rely on message-passing protocols: their correctness largely depends on sound protocol implementations. Session types can help in the specification of correct-by-construction systems, and in verifying that programs respect their intended protocols. Recent years have seen a steady stream of research on behavioural types: their foundations and their transfer to several programming languages. This has led to highly-cited papers in conferences such as POPL and journals such as TOPLAS. Research projects on behavioural types have advanced the theory and applications of behavioural types. Although the foundations of session types are now well established, and new works build on approaches that have become standard, there is still a lack of reusable libraries, namely machine-verified ones. As on one hand the basis of most works is common, and on the other hand the complexity of the formal systems is considerable and may lead to errors in the proofs of the soundness results, machine verifying the type systems proposed is vital. Libraries, or at least clear formalisations of common approaches, is crucial to avoid not only to repeat work but also to increase the confidence in the knowledge base. Moreover, as many of these systems have a goal to do static analysis to ensure some safety or liveness property, machine verification of these approaches leads to certified software for program analysis. The goal of the VEST workshop is to gather the researchers working on mechanisations of behavioural types using various theorem provers, such as Agda, Coq, Isabelle or any other. The workshop will be a platform to present both the now well-established efforts and the ongoing works the community has put on verification. The workshop will also be a forum to discuss strengths and weaknesses of existing approaches, potential obstacles and to foster collaboration. * Types of Contributions We request two types of research contributions. Type 1: Short presentations (1 page) of work published elsewhere; Type 2: Presentations (2-5 pages) of ongoing original work. Submissions of Type 1 will consist of 1 page papers presenting the work, the publication venue and the significance of the results; the PC will select the submissions with a ranking system. Submissions of Type 2 will consist of 2 - 5 page papers submitted to a light reviewing process. There will be no proceedings of VEST'21, but rather the aim is to strengthen and further expand our community. * Important Dates AoE (UTC-12h) Submission: Monday, 3rd May 2021 Notification: Monday, 14th June 2021 Final Version: Monday, 5th July 2021 Workshop: Monday, 12th July 2021 * Submission Link: https://easychair.org/conferences/?conf= <https://easychair.org/conferences/?conf=beat2019>vest21 * Invited Speakers: - Jesper Bengtson (IT University of Copenhagen, Denmark) - Andreia Mordido (University of Lisbon, Portugal) *Tutorial, jointly delivered by: - David Castro-Perez (University of Kent, UK) - Francisco Ferreira-Ruiz (Imperial College, UK) - Lorenzo Gheri (Imperial College, UK) * Program Committee: - Robert Atkey, University of Strathclyde, UK - Laura Bocchi, University of Kent, UK - Ornela Dardha, University of Glasgow, UK (Co-chair) - Cinzia Di Giusto, Université Côte d'Azur, CNRS, I3S, France - Wen Kokke, The University of Edinburgh, UK - Robbert Krebbers, Radboud University Nijmegen, Netherlands - Luca Padovani , Università di Torino, Italy - Kirstin Peters, TU Darmstadt, Germany - António Ravara, NOVA University of Lisbon, Portugal (Co-chair) - Ivan Scagnetto, University of Udine, Italy - Peter Thiemann, Universität Freiburg, Germany

TABLEAUX 2021 The 30th International Conference on Automated Reasoning with Analytic Tableaux and Related Methods Birmingham, UK, September 6-9, 2021 Website: <https://tableaux2021.org/> https://tableaux2021.org/ Submission deadlines: 19 April (abstract), 26 April 2021 (paper) 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. 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: * tableau methods for classical and non-classical logics (including first-order, higher-order, modal, temporal, description, hybrid, intuitionistic, linear, substructural, fuzzy, relevance and non-monotonic logics) and their proof-theoretic foundations; * sequent, natural deduction, labelled, nested and deep calculi for classical and non-classical logics, as tools for proof search and proof representation; * related methods (SMT, model elimination, model checking, connection methods, resolution, BDDs, translation approaches); * 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, proof assistants, logical frameworks, model checkers, etc.); * implementation techniques (data structures, efficient algorithms, performance measurement, extensibility, etc.); * extensions of tableau procedures with conflict-driven learning; * techniques for proof generation and compact (or humanly readable) proof representation; * theoretical and practical aspects of decision 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 on logical aspects of the solution. SUBMISSION GUIDELINES Submissions are invited in the following two categories: (A) research papers reporting original theoretical research or applications, with length up to 15 pages excluding references; (B) 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-gui… IMPORTANT DATES Abstract submission: 19 April 2021 (AoE) Paper submission: 26 April 2021 (AoE) 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. PUBLICATION 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. TRAVEL GRANTS FOR STUDENTS Some funding may be available to support students participating at TABLEAUX 2021. More details will be given on the conference website in due time.
