Second Call for Papers - Runtime Verification RV'22 (Computational

von Thao Dang

[ Apologies for cross posting ] Runtime Verification 2022 CALL FOR PAPERS [ https://rv22.gitlab.io/ | https://rv22.gitlab.io ] We are pleased to invite you to submit papers for the 22nd International Conference on Runtime Verification (RV'22), which will take place as part of the Computational Logic Autumn Summit CLAS 2022 ( [ http://viam.science.tsu.ge/clas2022/ | http://viam.science.tsu.ge/clas2022/ ] ) in Tbilisi, Georgia, from September 28-30, 2022. ### Dates ### Paper submission: Thursday, 5 May 2022 Notification: Wednesday, 22 June 2022 Camera-ready: Sunday, 24 July 2022 Conference: 28-30 September 2022 Deadlines expire at 23:59 anywhere on earth on the dates displayed above. ### Conference Objectives and Scope ### Runtime verification is concerned with the monitoring and analysis of the runtime behaviour of software and hardware systems. Runtime verification techniques are crucial for system correctness, reliability, and robustness; they provide an additional level of rigor and effectiveness compared to conventional testing and are generally more practical than exhaustive formal verification. Runtime verification can be used prior to deployment, for testing, verification, and debugging purposes, and after deployment for ensuring reliability, safety, and security and for providing fault containment and recovery as well as online system repair. The topics of the conference include, but are not limited to: - specification languages for monitoring - monitor construction techniques - program instrumentation - logging, recording, and replay - combination of static and dynamic analysis - specification mining and machine learning over runtime traces - monitoring techniques for concurrent and distributed systems - runtime checking of privacy and security policies - metrics and statistical information gathering - program/system execution visualization - fault localization, containment, resilience, recovery and repair - systems with learning-enabled components - dynamic type checking and assurance cases - runtime verification for autonomy and runtime assurance Application areas of runtime verification include cyber-physical systems, autonomous systems, safety/mission critical systems, enterprise and systems software, cloud systems, reactive control systems, health management and diagnosis systems, and system security and privacy. ### Papers ### There are four categories of papers which can be submitted: regular, short, tool demo, and benchmark papers. Papers in each category will be reviewed by at least three members of the Program Committee. - Regular Papers (up to 16 pages, not including references) should present original unpublished results. We welcome theoretical papers, system papers, papers describing domain-specific variants of RV, and case studies on runtime verification. - Short Papers (up to 8 pages, not including references) may present novel but not necessarily thoroughly worked out ideas, for example emerging runtime verification techniques and applications, or techniques and applications that establish relationships between runtime verification and other domains. - Tool Demonstration Papers (up to 8 pages, not including references) should present a new tool, a new tool component, or novel extensions to existing tools supporting runtime verification. The paper must include information on tool availability, maturity, selected experimental results and it should provide a link to a website containing the theoretical background and user guide. Furthermore, we strongly encourage authors to make their tools and benchmarks available with their submission. - Benchmark Papers (up to 8 pages, not including references) should describe a benchmark, suite of benchmarks, or benchmark generator useful for evaluating RV tools. Papers should include information as to what the benchmark consists of and its purpose (what is the domain), how to obtain and use the benchmark, an argument for the usefulness of the benchmark to the broader RV community and may include any existing results produced using the benchmark. We are interested in both benchmarks pertaining to real-world scenarios and those containing synthetic data designed to achieve interesting properties. Broader definitions of benchmark e.g. for generating specifications from data or diagnosing faults are within scope. We encourage benchmarks that are tool agnostic, especially if they have been used to evaluate multiple tools. We also welcome benchmarks that contain verdict labels and with rigorous arguments for correctness of these verdicts, and benchmarks that are demonstrably challenging with respect to the state-of-the-art tools. Benchmark papers must be accompanied by an easily accessible and usable benchmark submission. Papers will be evaluated by a separate benchmark evaluation panel who will assess the benchmarks relevance, clarity, and utility as communicated by the submitted paper. The Program Committee of RV 2021 will give a Springer-sponsored Best Paper Award to one eligible regular paper. ### Submissions ### All papers and tutorials will appear in the conference proceedings in an LNCS volume. Submitted papers and tutorials must use the LNCS/Springer style detailed here: [ http://www.springer.de/comp/lncs/authors.html | http://www.springer.de/comp/lncs/authors.html ] . Springer encourages authors to include their ORCIDs ( [ https://www.springer.com/gp/authors-editors/orcid | https://www.springer.com/gp/authors-editors/orcid ] ) in their papers. Papers must be original work and not be submitted for publication elsewhere. Papers must be written in English and submitted electronically (in PDF format) using the EasyChair submission page here: [ https://easychair.org/conferences/?conf=rv2022 | https://easychair.org/conferences/?conf=rv2022 ] . The page limitations mentioned above include all text and figures, but exclude references. Additional details omitted due to space limitations may be included in a clearly marked appendix, that will be reviewed at the discretion of reviewers, but not included in the proceedings. At least one author of each accepted paper and tutorial must register and attend RV'22 to present.

LAMAS & SR 2022 - 1st Call for Contributions

von Fabio Mogavero

[Apologies for multiple cross-posting] -------------------------------------------------------------------------------- 1st Call for Contributions 2nd International Workshop on Logical Aspects in Multi-Agent Systems and Strategic Reasoning (LAMAS&SR) 2022 25-26 August 2022, Rennes, France URL: https://lamassr.github.io/ -------------------------------------------------------------------------------- Objectives ---------- Logics and strategic reasoning play a central role in multi-agent systems. Logics can be used, for instance, to express the agents’ abilities, knowledge, and objectives. Strategic reasoning refers to algorithmic methods that allow for developing good behaviour for the agents of the system. At the intersection, we find logics that can express existence of strategies or equilibria, and can be used to reason about them. The LAMAS&SR workshop merges two international workshops: LAMAS (Logical Aspects of Multi-Agent Systems), which focuses on all kinds of logical aspects of multi-agent systems from the perspectives of artificial intelligence, computer science, and game theory, and SR (Strategic Reasoning), devoted to all aspects of strategic reasoning in formal methods and artificial intelligence. List of Topics -------------- The topics covered by the workshop include, but are not limited to: * Logical systems for specification, analysis, and reasoning about multi-agent systems * Logic-based modelling of multi-agent systems * Dynamical multi-agent systems * Deductive systems and decision procedures for logics for multi-agent systems * Development and implementation of methods for verification in multi-agent systems * Logic-based tools for multi-agent systems * Logics for reasoning about strategic abilities * Logics for multi-agent mechanism design, verification, and synthesis * Logical foundations of decision theory for multi-agent systems * Strategic reasoning in formal verification * Automata theory for strategy synthesis * Applications and tools for cooperative and adversarial reasoning * Robust planning and optimisation in multi-agent systems * Risk and uncertainty in multi-agent systems * Quantitative aspects in strategic reasoning Invited Speakers ---------------- * Rineke Verbrugge, University of Groningen Co-Located Event ---------------- LAMAS&SR 2022 will be an event co-located with the 14th International Conference on Advances In Modal Logic (AiML 2022, 22-25 August). About COVID-19 -------------- Local organizers are following closely the evolution of the pandemic situation. Our preference is for a full in-person event, but we will employ an online or hybrid format according to the situation. Important Dates --------------- * Paper submission: May 23 (AoE) * Author notification: June 30 (AoE) * Camera ready: July 15 (AoE) * Workshop: August 25-26, 2022 Contribution Submission ----------------------- Authors are invited to submit extended abstracts of 2 pages, plus 1 page for references only, in the AAMAS 2022 format. Both published and unpublished works are welcome. Submissions are subject to a single-blind review process, thus, submissions should not be anonymous, must be in PDF format, and will be handled via EasyChair at https://easychair.org/conferences/?conf=lamassr22 Although there will be no formal proceedings, accepted extended abstracts will be made available on the workshop website. Extensions of selected original contributions will be then invited to a special issue of Games, an MDPI open-access journal, with a special arrangement.

Learning and Automata (LearnAut) 2022 -- ICALP 2022 Workshop, last

von Tobias Kappé

Learning and Automata (LearnAut) -- ICALP 2022 workshop July 4th - Paris, France and virtually Website: https://learnaut22.github.io Deadline: Extended to April 7th Submission portal: https://easychair.org/conferences/?conf=learnaut2022 Learning models defining recursive computations, like automata and formal grammars, are the core of the field called Grammatical Inference (GI). The expressive power of these models and the complexity of the associated computational problems are major research topics within mathematical logic and computer science. Historically, there has been little interaction between the GI and ICALP communities, though recently some important results started to bridge the gap between both worlds, including applications of learning to formal verification and model checking, and (co-)algebraic formulations of automata and grammar learning algorithms. The goal of this workshop is to bring together experts on logic who could benefit from grammatical inference tools, and researchers in grammatical inference who could find in logic and verification new fruitful applications for their methods. We invite submissions of recent work, including preliminary research, related to the theme of the workshop. The Program Committee will select a subset of the abstracts for oral presentation. At least one author of each accepted abstract is expected to represent it at the workshop (in person, or virtually). Note that accepted papers will be made available on the workshop website but will not be part of formal proceedings (i.e., LearnAut is a non-archival workshop). Topics of interest include (but are not limited to): - Computational complexity of learning problems involving automata and formal languages. - Algorithms and frameworks for learning models representing language classes inside and outside the Chomsky hierarchy, including tree and graph grammars. - Learning problems involving models with additional structure, including numeric weights, inputs/outputs such as transducers, register automata, timed automata, Markov reward and decision processes, and semi-hidden Markov models. - Logical and relational aspects of learning and grammatical inference. - Theoretical studies of learnable classes of languages/representations. - Relations between automata or any other models from language theory and deep learning models for sequential data. - Active learning of finite state machines and formal languages. - Methods for estimating probability distributions over strings, trees, graphs, or any data used as input for symbolic models. - Applications of learning to formal verification and (statistical) model checking. - Metrics and other error measures between automata or formal languages. ** Invited speakers ** Jeffrey Heinz (Stony Brook University) Sheila McIlraith (University of Toronto) Ariadna Quattoni (Universitat Politècnica de Catalunya) ** Submission instructions ** Submissions in the form of anonymized extended abstracts must be at most 8 single-column pages long at most (plus at most four for bibliography and possible appendixes) and must be submitted in the JMLR/PMLR format. The LaTeX style file is available here: https://ctan.org/tex-archive/macros/latex/contrib/jmlr We do accept submissions of work recently published or currently under review. - Submission url: https://easychair.org/conferences/?conf=learnaut2022 - Submission deadline: April 7th - Notification of acceptance: May 5th - Early registration: TBD ** Program Committee ** - Dana Angluin (Yale University) - Leonor Becerra-Bonache (Jean Monnet University, Saint-Étienne) - Jorge Castro (Universitat Politècnica de Catalunya) - Dana Fisman (Ben-Gurion University) - Matthias Gallé (Naver Labs Europe) - Gerco van Heerdt (University College London) - Colin de la Higuera (University of Nantes) - Falk Howar (TU Dortmund) - Nils Jansen (Radboud University) - Joshua Moerman (Open University of the Netherlands) - Ariadna Quattoni (Universitat Politècnica de Catalunya) - Bernhard Steffen (TU Dortmund) - Henning Urbat (Friedrich-Alexander University Erlangen-Nürnberg) - Frits Vaandrager (Radboud University) - Ryo Yoshinaka (Tohoku University) ** Organizers ** Rémi Eyraud (Jean Monnet University, Saint-Étienne) Tobias Kappé (ILLC, University of Amsterdam) Guillaume Rabusseau (Mila & DIRO, Université de Montréal) Matteo Sammartino (Royal Holloway, University of London & University College London)

April 5-6, 2022: Guarded Fragments: Current Trends and Applications (GF@25)

von Balder ten Cate

Guarded Fragments: Current Trends and Applications (GF@25) April 5-6, 2022, Fully Online Webpage: https://events.illc.uva.nl/GF25/ The Guarded Fragment (GF) was introduced in 1996 by Hajnal Andreka, Johan van Benthem and Istvan Nemeti, as a decidable fragment of first-order logic that aims to explain the attractive algorithmic and model theoretic behavior of modal logic. It subsequently gave rise to a larger family of decidable guarded fragments of first-order logic and second-order logic. These guarded fragments are, up to today, still actively studied and used in various application domains across different areas of computer science and artificial intelligence (e.g., data management, knowledge representation). This workshop is a celebration of the 25th anniversary of GF. It will showcase recent results, bringing together different strands of research, and offering an opportunity for reflection. The workshop is fully online, with a program consisting of 7 invited lectures, spread out across two days.

Call for papers: QBF '22

von HUBERT MING CHEN

CALL FOR PAPERS QBF 2022 -------- International Workshop on Quantified Boolean Formulas and Beyond August 1, 2022 To be held in hybrid format (virtually + in-person). https://www.ac.tuwien.ac.at/qbf2022/ Affiliated to and co-located with: Int. Conf. on Theory and Applications of Satisfiability Testing (SAT 2022), August 2-5, 2022. ------------------------------------------------------------- Quantified Boolean formulas (QBF) are an extension of propositional logic which allows for explicit quantification over propositional variables. The decision problem of QBF is PSPACE-complete, compared to the NP-completeness of the decision problem of propositional logic (SAT). Many problems from application domains such as model checking, formal verification or synthesis are PSPACE-complete, and hence could be encoded in QBF in a natural way. Considerable progress has been made in QBF solving throughout the past years. However, in contrast to SAT, QBF is not yet widely applied to practical problems in academic or industrial settings. For example, the extraction and validation of models of (un)satisfiability of QBFs has turned out to be challenging, given that state-of-the-art solvers implement different solving paradigms. The goal of the International Workshop on Quantified Boolean Formulas (QBF Workshop) is to bring together researchers working on theoretical and practical aspects of QBF solving. In addition to that, it addresses (potential) users of QBF in order to reflect on the state-of-the-art and to consolidate on immediate and long-term research challenges. The workshop also welcomes work on reasoning with quantifiers in related problems, such as dependency QBF (DQBF), quantified constraint satisfaction problems (QCSP), and satisfiability modulo theories (SMT) with quantifiers. =============== IMPORTANT DATES =============== May 1: Submission June 5: Notification of acceptance June 19: Final versions of accepted papers due August 1: Workshop Please see the workshop webpage for any updates: https://www.ac.tuwien.ac.at/qbf2022/ ====================== CALL FOR CONTRIBUTIONS ====================== The workshop is concerned with all aspects of current research on all formalisms enriched by quantifiers, and in particular QBF. The topics of interest include (but are not limited to): Applications, encodings and benchmarks with quantifiers QBF Proof theory and complexity results Experimental evaluations of solvers or related tools Case studies illustrating the power of quantifiers Certificates and proofs for QBF, QCSP, SMT with quantifiers, etc. Formats of proofs and certificates Implementations of proof checkers and verifiers Decision procedures Calculi and their relationships Data structures, implementation details and heuristics Pre- and inprocessing techniques Structural reasoning ========== SUBMISSION ========== Submissions of extended abstracts are invited and will be managed via Easychair: https://easychair.org/conferences/?conf=qbf2022 In particular, we invite the submission of extended abstracts on work that has been published already, novel unpublished work, or work in progress. The following forms of submissions are solicited: - Proposals for short tutorial presentations on topics related to the workshop. Tutorial proposals will be reviewed by the PC. The number of accepted tutorials depends on the overall number of accepted papers and talks, with the aim to set up a balanced workshop program. - Talk abstracts reporting on already published work. Such an abstract should include an outline of the planned talk, and pointers to relevant bibliography. - Talk proposals presenting work that is unpublished or in progress. - Submissions which describe novel applications of QBF or related formalisms in various domains are particularly welcome. Additionally, this call comprises known applications which have been shown to be hard for QBF solvers in the past as well as new applications for which present QBF solvers might lack certain features still to be identified. Each submission should have an overall length of 1-4 pages in LNCS format. Authors may decide to include an appendix with additional material. Appendices will be considered at the reviewers' discretion. The accepted extended abstracts will be published on the workshop webpage. The workshop does not have formal proceedings. Authors of accepted contributions are expected to give a talk at the workshop. ======= CONTACT ======= qbf2022(a)easychair.org ================= PROGRAM COMMITTEE ================= Hubie Chen, Birkbeck, University of London Florian Lonsing, Stanford University Martina Seidl, JKU Linz Friedrich Slivovsky, TU Wien
