In Memoriam: Deepak Kapur

Deepak Kapur passed away on April 11, 2026 in Albuquerque, New Mexico, aged 75. He was one of the pioneers of automated reasoning, with outstanding contributions in numerous areas, including inductive theorem proving, geometry theorem proving, term rewriting, unification theory, integration and combination of decision procedures, lemma and loop invariant generation, as well as his work to bridge the gap between computer algebra and automated deduction.

After graduating from the Indian Institute of Technology (IIT) in Kanpur, Deepak earned his Ph.D. in 1980 at MIT under the supervision of Barbara Liskov. From 1980 to 1987 he worked at General Electric's Research Laboratory in Schenectady, New York, while also serving as an adjunct professor at Rensselaer Polytechnic Institute. He was appointed full professor at the University at Albany, State University of New York in 1988. In 1998, Deepak moved to the University of New Mexico (UNM) in Albuquerque, where he was Chair of the Computer Science Department until 2006 and was awarded Distinguished Professor in 2007.

In automated deduction, Deepak introduced one of the most influential approaches for automated program verification by induction, the "proof by consistency" method. This approach had an enormous impact on the further development of the field. His research covered both deep theoretical contributions and practical aspects concerning the application of his results. His induction theorem prover "Rewrite Rule Laboratory (RRL)" was very influential and was successfully used for numerous applications, in particular in hardware verification. Deepak's work on the foundations of RRL forms the basis of many modern theorem provers, since RRL was one of the first tools that successfully combined theorem proving and decision procedures.

Another topic of Deepak's work was termination analysis, in particular for systems where certain functions have additional properties like associativity and commutativity. His results on techniques for termination proofs of such systems had a wide influence and remain among the most powerful ones today.

Moreover, Deepak made fundamental contributions to several other topics in automated deduction, such as methods for unification, for proving sufficient completeness, etc.

In the area of computer algebra, Deepak developed very substantial contributions on algebraic and geometric reasoning. Here, his focus was on developing methods for solving geometric problems and for determining geometric quantities. Moreover, Deepak found a fascinating way to combine results from both computer algebra and automated deduction by using methods from algebraic geometry to generate loop invariants automatically.

His position as one of the leaders of automated deduction is demonstrated by the fact that he was the editor-in-chief of the Journal of Automated Reasoning from 1993 to 2007, he served as CADE program chair in 1992, and he received the Herbrand Award in 2009 in recognition of his seminal contributions to automated reasoning.

Deepak was also a very devoted teacher and mentor for both students and younger researchers. I was fortunate to spend a year working with him as a visiting researcher at UNM in 1999/2000. His advice, suggestions, and friendship have guided me ever since.

Deepak is survived by his wife Roli Varma and their daughter Ila.

We plan to hold a memorial session at IJCAR during FLoC in Lisbon, July 2026, where everybody is welcome to share memories of Deepak. If you would like to speak a few words during this session, please contact Jürgen Giesl by June 26, 2026.

Announcement of the 2026 Herbrand Award

Jürgen Giesl
President of CADE Inc.
On behalf of the 2026 Herbrand Award Committee

The International Conference on Automated Deduction (CADE) Herbrand Award for Distinguished Contributions to Automated Reasoning is presented to

Frank Pfenning

for contributions to the foundations of type theory and logical frameworks, and the development of theory, automated tools, and applications for classical and non-classical logics.

Presented at IJCAR 2026, the 13th International Joint Conference on Automated Reasoning.

The 2026 Herbrand Award Committee consisted of Nikolaj Bjørner (Chair), Amy Felty, Cynthia Kop, Cláudia Nalon, Andrew Reynolds, and Geoff Sutcliffe.

Announcement of the 2026 McCune Award

Jürgen Giesl
President of CADE Inc.
On behalf of the 2026 Bill McCune PhD Award Committee

The International Conference on Automated Deduction (CADE) Bill McCune PhD Award in Automated Reasoning is presented to

Jasper Nalbach

for his dissertation “Cylindrical Algebraic Decomposition Based Methods in Satisfiability Modulo Non-linear Real Arithmetic” supervised by Prof. Dr. Erika Ábrahám and Prof. Dr. James Davenport. The thesis was selected for its strong theoretical contributions to SMT solving for non-linear real arithmetic. The thesis provides a uniform presentation of available algorithms based on the cylindrical algebraic decomposition (CAD) method for satisfiability checking and quantifier elimination; the CAD projection is formalized as a proof system, which allows the design of fine-grained optimizations. These theoretical results are not only important for the understanding, improvement, and applicability of exploration-guided CAD-based algorithms, but also proved to have impact on the development of practically relevant software.

Presented at IJCAR 2026, the 13th International Joint Conference on Automated Reasoning.

The 2026 Bill McCune PhD Award Committee consisted of Viorica Sofronie-Stokkermans (chair), Pascal Fontaine, Carsten Fuhs, Ullrich Hustadt, Mikoláš Janota, Cezary Kaliszyk, Philipp Rümmer, and Sophie Tourret.


An honorary mention is given to

Joseph Reeves

for his dissertation “Cardinality Constraints in Boolean Satisfiability Solving” supervised by Prof. Marijn Heule and Prof. Randal Bryant. The thesis was selected for its impact on the theory and practice of SAT solving. The thesis introduces KNF (AtLeastK Conjunctive Normal Form), an extension of conjunctive normal form with native cardinality constraint support, and develops native cardinality propagation and an efficient form of cardinality-guided formula splitting for parallel solving. The thesis makes a convincing case for enriching the input of SAT solvers with cardinality constraints by demonstrating the substantial performance improvements that can be achieved through cardinality-aware reasoning, even without using cutting planes.

Presented at IJCAR 2026, the 13th International Joint Conference on Automated Reasoning.

The 2026 Bill McCune PhD Award Committee consisted of Viorica Sofronie-Stokkermans (chair), Pascal Fontaine, Carsten Fuhs, Ullrich Hustadt, Mikoláš Janota, Cezary Kaliszyk, Philipp Rümmer, and Sophie Tourret.

Book Announcement: Concise Introduction to Alternating-Time Temporal Logics

The formal verification of multi-agent systems aimed at proving that such systems meet their specifications has given rise to a very active field of research at the crossroads of formal methods, knowledge representation and artificial intelligence. Alternating-time temporal logics are considered as one of the most popular and influential logical formalisms for strategic reasoning in multi-agent systems and have been introduced by Rajeev Alur, Thomas Henzinger and Orna Kupferman about 25 years ago.

This textbook provides a concise presentation of alternating-time temporal logics devoted to strategic reasoning in multi-agent systems. Dedicated mainly to the model-checking problem, the work examines developments about basic semantical properties of such logics, decision procedures and computational complexity. It provides results for solving optimally the model-checking problem on concurrent game structures by taking advantage of—or adapting proof methods from—temporal logics, games in theoretical computer science and automata theory.

FMAS 2026: 8th Workshop on Formal Methods for Autonomous Systems, call for papers

November 17–18, 2026, Southampton, UK (co-located with ICFEM 2026)

FMAS is a 2-day peer-reviewed international workshop that brings together researchers working on a range of techniques for the formal verification of autonomous systems to present recent work in the area, discuss key challenges, and stimulate collaboration between autonomous systems and formal methods researchers.

Autonomous systems present unique challenges for formal methods. They are often embodied in robotic systems that can interact with the real world, and they make independent decisions. Amongst other categories, they can be viewed as safety-critical, cyber-physical, hybrid, and real-time systems.

Key challenges for applying formal methods to autonomous systems include:

  • the system’s dynamic deployment environment;
  • verifying the system’s decision making capabilities – including planning, ethical, and reconfiguration choices; and
  • using formal methods results as evidence given to certification or regulatory organisations.

FMAS welcomes submissions that use formal methods to specify, model, or verify autonomous systems; in whole or in part. We are especially interested in work using integrated formal methods, where multiple (formal or non-formal) methods are combined during the software engineering process. We encourage submissions that are advancing the applicability of formal methods for autonomous systems, for example improving integration or explainability, automation or knowledge transfer of these technique.

Autonomous systems are often embedded in robotic or cyber-physical systems, and they share many features (and verification challenges) with automated systems. FMAS welcomes submissions with applications to automated systems, semi-autonomous systems, or fully-autonomous systems.

Topics of interest include (but are not limited to):

  • Applicable, tool-supported formal methods suited to autonomous systems
  • Runtime verification or other formal approaches to deal with the reality gap
  • Verification against safety assurance arguments or standards documents
  • Formal specification, modelling, and requirements engineering for autonomous systems
  • Case studies that identify challenges when applying formal methods to autonomous systems
  • Experience reports providing guidance for tackling challenges with formal methods or tools
  • Discussions of future directions of the field

In addition to the topics above, we would like to invite work on formal methods for intersymbolic AI. Intersybolic AI refers to the combination of symbolic AI (logic, knowledge graphs, etc.) and subsymbolic AI (neural networks, reinforcement learning, etc.).

Important Dates (AoE)

  • Abstract deadline: August 14, 2026
  • Paper deadline: August 17, 2026
  • Notification: October 6, 2026

Competitions

TermComp 2026: Termination and Complexity Competition

July 24–25, 2026, Lisbon, Portugal (co-located with WST 2026, part of FLoC 2026)

During the 90's a number of new, powerful termination methods was developed. Thus, at the beginning of the millennium many research groups started to develop tools for fully-automated termination analysis.

After a tool demonstration at the Termination Workshop 2003 (Valencia), the community then decided to install an annual termination competition, and to collect benchmarks, to spur the development of tools and new termination techniques.

The competition will be run on the RWTH Aachen High Performance Computing Cluster. Test runs will take place right after the submission deadline, followed by a bug/conflict reporting phase. Bug fixes will be possible until shortly before the full run. A live run on a subset of the benchmark collection, and a presentation of the final results will take place at WST.

Important Dates (AoE)

  • Tool and benchmark submission: June 26, 2026
  • Full run: July 13–17, 2026
  • Live run: July 24–25, 2026

ProoVer-2026: First Proof Verifier Competition

July 27, 2026, Lisbon, Portugal (co-located with CASC-J13 at IJCAR 2026, part of FLoC 2026)

ProoVer-2026 is the first edition of the annual competition for automatic proof verifiers. In ProoVer, verifiers are given a mix of valid proofs and evil proofs in which tricky errors have been deliberately introduced. The goal is to correctly identify which proofs are valid and which are flawed.

Participants submit proof verifier systems that receive FOF (First-Order Form) problems paired with TSTP-format proofs, and must determine whether each proof is valid or flawed. For this first edition, only a limited set of inference rules and formula roles will be used: Axiom, Conjecture, NegatedConjecture, Skolemization, as well as plain steps whose correctness should be delegated to an external ATP. Each system is evaluated on 100 problems: 50 valid proofs and 50 evil proofs, with a time limit of 30 seconds per problem (wall-clock). The competition infrastructure is shared with CASC (StarExec).

As ProoVer is held jointly with CASC, we will have a shared dinner and if you participate in both competitions, registration fees are charged only once.

Important Dates (AoE)

  • System registration deadline: June 29, 2026
  • System descriptions deadline: July 13, 2026
  • Formal ProoVer registration: July 13, 2026

Postdoctoral Position in Interactive Theorem Proving and Blockchain Technologies, LIG, Grenoble, France

A one-year postdoctoral position (renewable) is available in the CAPP group at the Computer Science Laboratory of Grenoble (LIG). The position focuses on the formalization of protocols in decentralized finance within the proof assistant Isabelle/HOL, with the goal of developing rigorous theoretical results and certified tools for optimizing decentralized finance transactions. The LIG is one of the leading computer science research laboratories in France, located on the University Grenoble Alpes campus, at the foot of the Alps. The CAPP group research lies at the intersection of logic, programming languages, and proofs.

Automated Market Makers are the cornerstones of Decentralized Finance (DeFi), eliminating the need for traditional order books. In this ecosystem, Liquidity Providers stake tokens to facilitate swaps for Liquidity Takers in exchange for fees. Concentrated Liquidity Market Makers (CLMMs), introduced by Uniswap v3, have revolutionized this space by allowing providers to allocate liquidity within specific price intervals. This model significantly improves capital efficiency compared to uniform distribution models and has been adopted by several major protocols. Despite implementation variations (fees, tick spacing), these protocols share core principles. Consequently, liquidity takers often face multiple pools for the same token pair with different characteristics. A critical challenge is to rigorously understand how these pools can be combined, both conceptually and computationally, for liquidity takers to perform transactions with the least slippage (recovering as many tokens as possible in exchange for those they provide).

Decentralized finance refers to a set of peer-to-peer exchange protocols designed to minimize the dependence on intermediaries and central authorities. As DeFi becomes increasingly important in modern economies, establishing rigorous theoretical foundations for its core mechanisms is essential. The project aims to develop a rigorous formal framework for reasoning about the behavior of Concentrated Liquidity Market Makers and optimizing execution of transactions across multiple pools. A significant formalization effort regarding the behavior of CLMMs in Isabelle/HOL has already been initiated within the group. The recruited postdoctoral researcher will be responsible for advancing this work.

The primary objectives are:

  • Advance the Formalization: Continue the ongoing effort in Isabelle/HOL to create a rigorous logical framework representing CLMM states and transaction dynamics.
  • Generalization: Work on weakening the initial hypotheses of the current model to generalize results on optimal execution strategies.
  • Tool Development: The formalization should leverage Isabelle/HOL's code generation capabilities to derive a certified decision-aid tool for optimizing simultaneous transactions across multiple pools.
  • Real-case analyses: Evaluate the resulting tool in real-world conditions, taking into account the impact of gaz fees and bridging constraints between blockchains.

Candidates should have a strong background in Logic, Formal Methods, Proof Theory, or Semantics. Experience with proof assistants (e.g., Coq, Lean, Isabelle/HOL) or formal verification tools, as well as familiarity with DeFi concepts (AMMs, Smart Contracts) are also welcomed.

The start date is flexible, but ideally, as soon as possible. Interested candidates should send their CV, a cover letter, links to their thesis and/or relevant papers, and contact information for two references to Mnacho Echenim and Nicolas Peltier.

PhD Position in Formal Verification of Distributed Systems using Reinforcement Learning, Mitsubishi Electric R&D Centre Europe & Inria Rennes, France

A PhD position is open on the formal verification of distributed systems with respect to liveness properties using reinforcement learning techniques.

Mitsubishi Electric R&D Centre Europe and Irisa / Inria Rennes are interested in developing algorithms for automatically proving the absence of livelocks or detecting livelocks bugs in distributed protocols using reinforcement learning algorithms. We suggest developing deep RL algorithms to analyze maximal wait times in distributed protocols. The wait time is the number of steps a process is executed before it gains access to a resource. There are no livelocks if the wait times are always finite. The work consists in modeling this problem as an RL problem, choosing the right rewards and RL algorithms, and making sure it scales to real implementations of distributed algorithms.

Because the overall goal is formal verification, the computed neural policy must be formally verified at the end. This can be achieved using SMT solvers or specific abstract interpretation techniques for neural networks.

The model and RL algorithms can be chosen either to attempt to prove the absence of livelocks and compute bounds on wait times, or to detect livelock bugs. The precise direction to be taken and the weight given to RL versus formal verification in this work can be chosen according to the student’s background and preferences.The work also includes an extensive bibliographic study, the development of the above algorithms, implementation and experiments.

The successful candidate must have an excellent theoretical background in formal methods (or alternatively in reinforcement learning), good programming skills, knowledge (course work, internship, or master's thesis) in at least one of the two fields: reinforcement learning, and formal verification or logic, previous research experience (e.g., internships), strong references, and a strong motivation to learn.

Internship in Formal Verification of Systems Software, AWS, Cambridge, UK

The Automated Reasoning Group at AWS in Cambridge is seeking internship candidates to work on formal verification of low-level systems software. Among other things, the hosting team is responsible for the formal verification of the Nitro Isolation Engine, a new separation kernel for Graviton cloud instances.

The ideal candidate is a student towards the end of their PhD with a strong background in interactive theorem proving, ideally but not necessarily Isabelle, and some familiarity with systems programming, ideally in Rust. Details are TBD, but potential topics include hands-on proof development, refining our large-scale separation logic proof automation, or improving AI / ITP integration.

Interested candidates should reach out directly to Hanno Becker.

Senior Software Engineer, Nectry, Remote

Nectry is building the governance layer for AI-generated code in regulated enterprises. Our core technology, NectryCore, is a purpose-built DSL and compiler that makes formal verification and policy enforcement structurally guaranteed, not bolted on. We're a small, ambitious team, and we're looking for an engineer who loves type systems, takes ownership, and wants to use AI tools to build things that actually have to be correct.

You'll work across our stack on language design, tooling, and product engineering. Most of our application code is written in Ur/Web, a statically-typed functional language for web programming. We don't expect you to know Ur/Web on day one, but we expect you to be the kind of engineer who picks up an unfamiliar functional language quickly.

This is a senior, high-autonomy role: you'll scope your own work, own systems end-to-end, and shape technical direction alongside our co-founders, including our Chief Scientist Adam Chlipala (MIT professor, creator of Fiat Cryptography and Ur/Web).

To apply, send a short note about what you have been working on, why functional programming matters to you, and anything you are proud of (code, papers, projects). More information is available on the job offer page.
