by DESTERCKE Sébastien

Dear colleagues, We are delighted to announce our upcoming SIPTA online seminar on imprecise probabilities (IP). These monthly events are open to anyone interested in IP, and will be followed by a Q&A and open discussion. They also provide an occasion for the community to meet, keep in touch and exchange between in-person events. The next seminar will take place on the 29th of January (Thursday). The zoom link for this seminar is https://utc-fr.zoom.us/j/85306809920 For this new seminar, we are very happy to have Eric Goubault as our speaker. Eric Goubault is currently the head of the computer science department at the Ecole polytechnique, and is in charge of the "Engineering of Complex Systems" academic and research chair. His research focuses on the verification of numerical programs and systems, on geometric methods for concurrency, directed topology and applications to verification of concurrent, distributed and fault-tolerant computing. He has notably made different contributions mixing system verification with imprecise probabilistic approaches. On the 29th of January, at 15:00 CEST:paris time (up to 17:00 CEST, with a talk duration of 45min/1h), he will talk about "Verification of Cyber-physical systems”. Curious? Then check out the abstract on the webpage of the SIPTA seminars: sipta.org/events/sipta-seminars. The zoom link for attending the seminar can be found on that same page. So please mark your calendars on the 29th of January, and join us for the occasion.

Recent book: "Arbitrage and Rational Decisions"

by Bob Nau

Dear SIPTA colleagues, I’d like to spread a few words about the recent publication of my book “Arbitrage and Rational Decisions”. Publisher links, supporting materials, and a free draft copy of the entire book can be found at this web site: https://people.duke.edu/~rnau/book/Arbitrage_and_Rational_Decisions.htm It was in progress for many years, dating back to the dawn of SIPTA, but the issues that it considers are foundational and still timely. It presents a unified view of the foundations of rational choice theory: subjective probability and expected utility theory, state-preference theory, non-expected utility theory, noncooperative game theory, asset pricing theory, and social aggregation. The unifying theme is the principle of no-arbitrage, i.e., avoidance of sure loss at the hands of other actors in your scene. In the context of subjective probability this is de Finetti’s concept of coherence, but it applies across the whole spectrum and leads to representation theorems that have a common structure in which a hyperplane (or many thereof) separates the convex set of arbitrage opportunities from the convex set of acceptable bets or trades, and the coordinates of the normal vector(s) are the observable parameters of the decision maker’s mind. Imprecision in probabilities, utilities, state prices, and noncooperative equilibria is a natural state of affairs within this framework. A running theme is that it makes a great deal of difference whether money is available as a medium of exchange and betting and (less well appreciated) as a language for constructing common knowledge of beliefs and tastes and reciprocal stakes in events in numerical terms. De Finetti had the right idea in using monetary bets as a measuring device. Nonlinear and/or state-dependent utility for money and/or non-expected-utility preferences are not problematic. They merely change the visible units of analysis from personal probabilities to risk-neutral probabilities, as in asset pricing theory. Probabilities do not need to be uniquely separated from utilities. When the setting is a noncooperative game, this method of analysis leads (via a slight twist on de Finetti’s theorem) to the result that Aumann’s correlated equilibrium, not Nash equilibrium, is the fundamental solution concept, which is illustrated on the book’s cover. The generic solution of a game is imprecise: a convex set of correlated equilibrium distributions. I hope that you may find some of these perspectives to be of interest. Cheers and best wishes, --Bob --------------------------------------------------- Robert Nau Fuqua School of Business Duke University https://www.fuqua.duke.edu/faculty/robert-nau ---------------------------------------------------

1st Call for Papers of QEST+FORMAT 2026

by Marco Paolieri

======================================= 1st Call for Papers of QEST+FORMAT 2026 September 2-4, 2026, Liverpool, UK https://www.qest-formats.org/ https://confest-2026.github.io/ ======================================= Tentative Dates: Abstract submission: April 3, 2026 Paper submission: April 10, 2026 Artifact submission: April 17, 2026 Author notification: May 24, 2026 Camera-ready submission: June 14, 2026 ======================================= Scope and Topics The two flagship conferences QEST (International Conference on Quantitative Evaluation of SysTems) and FORMATS (International Conference on Formal Modeling and Analysis of Timed Systems) are pursuing a strategic process of joining forces and sparking a new joint conference for quantitative modelling, analysis, and verification. This culminated in 2024 in the first QEST+FORMATS joint conference. In 2026, the two conferences will form the third QEST+FORMATS joint conference, which will be held on 2-4 September 2026 in Liverpool, UK, as part of the CONFEST 2026 umbrella conference. The joint conference is the leading forum for the quantitative evaluation and verification of systems. QEST+FORMATS aims to promote the study of fundamental and practical aspects of systems with quantitative nature (such as probability, timing, and cost). It aims to bring together researchers from different disciplines who share interests in the modelling, design, and analysis of computational systems. Systems of interest include biological and chemical systems; computer networks; critical infrastructures; cyber-physical systems; data-driven AI systems; energy systems; hardware and software systems; industrial systems; mobility networks; and quantum systems. The QEST+FORMATS joint conference also aims to attract researchers interested in real-time issues in hardware design, performance analysis, real-time software, scheduling, semantics and verification of timed, hybrid, and probabilistic systems. In general, the conference aims to attract experts in quantitative and timed systems from any domain. Topics and scientific areas of interest include: --- Models and metrics for the correctness, performance, reliability, safety, and security of systems (stochastic, probabilistic, quantum, and non-deterministic models including Markov chains, automata, Petri nets, process algebra, and their variations); --- Languages and methods for the specification of quantitative properties of systems; --- Techniques, algorithms, and data structures for the analysis, evaluation, and verification of the above models, e.g., for model checking, testing, constraint solving, scheduling, optimization, and worst-case execution time analysis; --- Quantitative and probabilistic aspects of programming; --- Data-driven and machine-learning techniques for the analysis, prediction, and verification of quantitative properties of systems; --- Case studies that highlight the role of quantitative specification, modelling, and evaluation in the design and analysis of systems, with emphasis on emerging problems and technologies, or novel domains; --- Software tools to support the practical application of research results in all of the above areas. ======================================= Confirmed Invited Speakers Ezio Bartocci, TU Wien, Austria Kim Guldstrand Larsen, Aalborg University, Denmark ======================================= Submissions QEST+FORMATS 2026 considers three types of submissions (authors will be able to specify the type of contribution upon submission): --- Research papers: Theoretical and methodological contributions that advance the understanding of a topic or issue, or describe the development of new analysis processes and techniques. --- Case study papers: Contributions that present practical applications of quantitative methods to challenging real-world case studies. Case study papers shall provide detailed evaluation and insights, and highlight the value added to the domain experts. --- Tool papers: Contributions introducing new tools or significant improvements of existing ones, and the formalisms they support. These papers shall focus on the software architecture, practical implementation, and evaluation (e.g., usability, scalability, and effectiveness). Tool papers must be accompanied by an artifact in the Artifact Evaluation as detailed below. All three types of papers can be regular or short: --- Regular papers must not exceed 16 pages, excluding references. --- Short papers should be limited to 7 pages, also excluding references. --- All papers can have an appendix containing supporting material. Note that reviewers are not required to read the appendix to fully assess the merits of the paper. We are considering additional presentation-only submission types; details will be provided in the later CfPs. All papers must be submitted in Springer's LNCS format and will undergo a rigorous single-blind review process. All submitted papers must be unpublished and not be submitted for publication elsewhere. Papers should be submitted electronically using EasyChair (Track: QEST+FORMATS 2026). Springer encourages authors to include their ORCIDs in their papers. Authors should consult Springer's authors' guidelines and use Springer's LaTeX templates for the preparation of their papers. Submitted papers not complying with the above guidelines may be rejected without undergoing review. We are considering awards for best papers and best artifacts. ======================================= Publications All accepted papers need to be presented and discussed at the conference by one of the authors. Similarly to last year, the QEST+FORMATS 2026 proceedings will be published in the Springer LNCS series indexed by ISI Web of Science, Scopus, ACM Digital Library, DBLP, Google Scholar. All submitted papers will be evaluated by at least three reviewers on the basis of their originality, technical quality, scientific or practical contribution to the state of the art, methodology, clarity, and adequacy of references. ======================================= Special Issue We are working on a special issue in a Q1 journal. A selection of the best papers will be invited to submit an extended version of their work to a special issue in an internationally recognized journal. ======================================= Artifact Evaluation Reproducibility of experimental results is crucial to foster an atmosphere of trustworthy, open, and reusable research. To improve and reward reproducibility, QEST+FORMATS 2026 will include a dedicated Artifact Evaluation (AE). Submission of an artifact is mandatory for tool papers (both regular and short), and optional but encouraged for research and case study papers where it can support the results presented in the paper. More details will follow.
