Call for Nominations: CADE Trustees Elections

Philipp Rümmer
Secretary of AAR and CADE

The affairs of CADE are managed by its Board of Trustees. This includes the selection of CADE (IJCAR) co-chairs, the selection of CADE venues, choosing the Herbrand Award selection committee, instituting new awards, etc.

Nominations for two CADE trustee positions are being sought, in preparation for the elections to be held after CADE-28.

The current members of the board of trustees are (in alphabetical order):

The terms of Christoph Benzmüller and Stephan Schulz end. Stephan Schulz may be nominated for a second term, whereas Christoph Benzmüller has already served two consecutive terms and cannot be nominated this year.

The term of office of André Platzer as CADE-28 programme chair ends after the CADE conference. As outgoing ex-officio trustee, André Platzer is eligible to be nominated as elected trustee.

In summary, we are seeking to elect two trustees.

Nominees must be AAR members. Nominations can be made by any CADE member, either by e-mail or at the CADE business meeting at CADE-28; since nominators must be CADE members, they must have participated at at least one of the CADE or IJCAR conferences in the years 2018-2021. Two members, a principal nominator and a second, are required to make a nomination, and it is their responsibility to ask people's permission before nominating them. A member may nominate or second only one candidate. For further details please see the CADE Inc. bylaws at the CADE web site.

Guest Column: The power of proof certificates

Chantal Keller,
LMF, Université Paris-Saclay

More and more automatic theorem provers output evidence of their answers. When they derive the unsatisfiability of a given conjunction of formulas, these witnesses are called proof certificates. They are used to increase the confidence in these provers by checking a posteriori their claims, as well as for proof reconstruction to enjoy automation in interactive provers without increasing their trusted base. A major example is the check in the Coq proof assistant of the proof of the Boolean Pythagorean Triples problem, which was encoded into a Boolean unsatisfiability problem generating a raw proof certificate of 200 terabytes in size.

Certificates can be understood in a very large sense as an evidence that the result of a program satisfies the expected specification. Now widely spread in the automated reasoning community, another example is their use to validate some compilation phases. Verifiable computing, which allows one to check the result of any program with high probability by a cryptographic approach (also satisfying zero-knowledge properties), can be seen as a universal certificate of the execution of a program - but saying nothing on the functional correctness of the program.

Let us come back to automated reasoning.

Certificates for Boolean unsatisfiability are largely studied and optimized, with formats such as D/LRAT or DRUP which have a good balance between the difficulty to generate certificates, to check certificates, and the size of certificates. However, for more expressive solvers, a curse of Babel starts to appear: for instance, while formats have been proposed for Satisfiability Modulo Theory (SMT) solvers, no standard has emerged yet. TPTP provers could be seen as enjoying a common certificate format, but if the syntax is indeed standardized - which is already a good point for parsing - the semantics is not since any prover may use its own set of inference rules.

Then, what should the requirements on these inference rules be? At first sight, it seems that they should be simple enough so that it is "easy" to check them. In this statement, "easy" could be understood in different (possibly compatible) ways: in terms of computational complexity, or of logical atomicity. Unfortunately, this is contradictory with other requirements: they should be easy to output for provers, and they should also be small enough to be stored in memory.

My claim is that these two problems - different formats, and the contradiction in the requirements of the formats - are actually not so important, thanks to the power of certificates.

The power is that, for all the applications of certificates listed above, we actually do not care about the correctness of certificates. What we do care about is the correctness of the answer of the prover. Certificates are only a way to help establishing this latter, but they can be manipulated, completed, etc as much as needed to actually get convinced of the answer.

With this in mind, the first problem - the difference between formats - can be solved by means of encodings between formats, those encodings having no need to be trusted. Regarding the second problem, a certificate only containing one step is of course useless, but even few steps - and even non-atomic ones - are already of good help if they can be given (maybe on demand) to some tools dedicated to these particular steps that can progressively refine the certificate. An example is that an SMT solver may not detail Boolean and theory reasoning, as long as it separates them so that they can be detailed by as many (simpler) tools as kinds of reasoning.

So what is a good certificate format? It is actually a *documented* format, such that, for each step, one can identify the fragment that it handles, and thus how to encode it in another format or to refine it with another tool. Certificates are spreading across domains, for instance proof of programs, thanks to this flexibility and interoperability.


New Software Foundations title: Separation Logic Foundations by Arthur Charguéraud

The Software Foundations team is pleased to announce another new volume in the series and significant updates to other volumes.

New Volume
Software Foundations volume 6, Separation Logic Foundations, by Arthur Charguéraud, is an in-depth introduction to separation logic—a practical approach to modular verification of imperative programs—and how to build program verification tools on top of it.

Updated Volume
Volume 2, Programming Language Foundations, surveys the theory of programming languages, including operational semantics, Hoare logic, and static type systems. The concrete notations in this volume have been extensively revamped for better readability, using the advanced Notation features of recent versions of Coq.

The other volumes in the series have been updated to track the current Coq release and incorporate many large and small improvements made since the last release. Watch for a major update to Volume 5, Verifiable C, later this summer!

All Software Foundations titles are available electronically, free of charge.

Functional Algorithms, Verified! by Tobias Nipkow et al.

This book is an introduction to data structures and algorithms for functional languages, with a focus on proofs. It covers both functional correctness and running time analysis. It does so in a unified manner with inductive proofs about functional programs and their running time functions. All proofs have been machine-checked by the proof assistant Isabelle.

The book can be freely downloaded here.

SETTA 2021: Symposium on Dependable Software Engineering: Theories, Tools and Applications, call for papers

November 25-27, 2021, Beijing, China

Formal methods emerged as an important area in computer science and software engineering about half a century ago. An international community is formed researching, developing and teaching formal theories, techniques and tools for software modeling, specification, design and verification. However, the impact of formal methods on the quality improvement of software systems in practice is lagging behind. This is for instance reflected by the challenges in applying formal techniques and tools to engineering large-scale systems such as Cyber-Physical Systems (CPS), Internet-of-Things (IoT), Enterprise Systems, Cloud-Based Systems, and so forth.

The purpose of the SETTA symposium is to bring international researchers together to exchange research results and ideas on bridging the gap between formal methods and software engineering. The interaction with the Chinese computer science and software engineering community is a central focus point. The aim is to show research interests and results from different groups so as to initiate interest-driven research collaboration. The SETTA symposium is aiming at academic excellence and its objective is to become a flagship conference on formal software engineering in China.

To achieve these goals and contribute to the sustainability of the formal methods research, it is important for the symposium to attract young researchers into the community. Thus, this symposium encourages in particular the participation of young researchers and students.

XLoKR 2021: 2nd Workshop on Explainable Logic-Based Knowledge Representation, call for papers

6-8 November 2021 (exact date(s) TBD), Hanoi, Vietnam (virtually)
co-located with KR 2021

Remote Participation due to COVID-19 Pandemic We understand that the global public health situation may make it difficult or impossible for some, if not all, participants to travel to Hanoi. For this reason, we commit to allowing authors of accepted papers to present virtually and will work hard to enable the best possible experience for all conference participants.

Embedded or cyber-physical systems that interact autonomously with the real world, or with users they are supposed to support, must continuously make decisions based on sensor data, user input, knowledge they have acquired during runtime as well as knowledge provided during design-time. To make the behavior of such systems comprehensible, they need to be able to explain their decisions to the user or, after something has gone wrong, to an accident investigator.

While systems that use Machine Learning (ML) to interpret sensor data are very fast and usually quite accurate, their decisions are notoriously hard to explain, though huge efforts are currently being made to overcome this problem. In contrast, decisions made by reasoning about symbolically represented knowledge are in principle easy to explain. For example, if the knowledge is represented in (some fragment of) first-order logic, and a decision is made based on the result of a first-order reasoning process, then one can in principle use a formal proof in an appropriate calculus to explain a positive reasoning result, and a counter-model to explain a negative one. In practice, however, things are not so easy also in the symbolic KR setting. For example, proofs and counter-models may be very large, and thus it may be hard to comprehend why they demonstrate a positive or negative reasoning result, in particular for users that are not experts in logic. Thus, to leverage explainability as an advantage of symbolic KR over ML-based approaches, one needs to ensure that explanations can really be given in a way that is comprehensible to different classes of users (from knowledge engineers to laypersons).

The problem of explaining why a consequence does or does not follow from a given set of axioms has been considered for full first-order theorem proving since at least 40 years, but there usually with mathematicians as users in mind. In knowledge representation and reasoning, efforts in this direction are more recent, and were usually restricted to sub-areas of KR such as AI planning and description logics. The purpose of this workshop is to bring together researchers from different sub-areas of KR and automated deduction that are working on explainability in their respective fields, with the goal of exchanging experiences and approaches. A non-exhaustive list of areas to be covered by the workshop are the following:

SOQE 2021: 2nd workshop on Second-Order Quantifier Elimination and Related Topics, call for papers

November 6-8, 2021, virtual
associated with KR 2021

Second-order quantifier elimination (SOQE) is the problem of equivalently reducing a formula with quantifiers upon second-order objects such as predicates to a formula in which these quantified second-order objects no longer occur. In slight variations, SOQE is known as forgetting, projection, predicate elimination, and uniform interpolation. It can be combined with various underlying logics, including propositional, model, description and first-order logics. SOQE and its variations bear strong relationships to Craig interpolation, definability and computation of definientia, the notion of conservative theory extension, abduction and notions of weakest sufficient and strongest necessary condition, and generalizations of Boolean unification to predicate logic. It is attractive as a logic-based approach to various computational tasks, for example, the computation of circumscription, the computation of modal correspondence properties, forgetting in knowledge bases, knowledge-base modularization, abductive reasoning and generating explanations, the specification of non-monotonic logic programming semantics, view-based query processing, and the characterization of formula simplifications in reasoner preprocessing.

Topics of interest include, but are not limited to:

The workshop aims to bring together researchers working on SOQE and all these related topics to present, discuss and compare issues shared by problems emerging from different special contexts, interesting open research problems (perhaps with partial solutions), new applications and implementation techniques.

FMTea 2021:Formal Methods Teaching Workshop and Tutorial, call for papers

November 21, 2021, online
Co-located with FM 2021

FMTea21 is a one-day combined workshop and tutorial that brings together researchers and educators working on formal methods to share their experiences in teaching formal methods, discuss key challenges, and stimulate collaboration that can lead to ways to reboot the presence of formal methods in curricula.

Objectives and Scope
Formal Methods provide software engineering with tools and techniques for rigorously reasoning about the correctness of systems. While in recent years formal methods are increasingly being used in industry, university curricula are not adapting at the same pace. Some existing formal methods classes interest and challenge students, whereas others fail to ignite student motivation. It is thus important to develop, share, and discuss approaches to effectively teach formal methods to the next generations. This discussion is now more important than ever due to the challenges and opportunities that arose from the pandemic, which forced many educators to adapt and deliver their teaching online. Exchange of ideas is critical to making these new online approaches a success and having a greater reach.

In the workshop part of the event, we welcome papers detailing experiences with FM Teaching, including papers discussing successes and failures of various methods, case studies, tools, etc. Given the increasing importance of online teaching and self-learning, we also welcome reports of experiences with online teaching, including experiences with teaching formal methods via MOOCs. We invite novel papers that cover, but are not limited to, the following aspects:

OVERLAY 2021, call for papers

September 22, 2021, Padova, Italy (unless held online, depending on the pandemic emergency situation)
co-located with GandALF 2021

COVID-19 Information
Taking into account the emergency situation, the organizers of OVERLAY 2021 will closely monitor the evolution of the pandemic and will take all the necessary actions to guarantee a successful event. In the case that an in-person event will not be possible, OVERLAY 2021 will be a hybrid or fully virtual conference. Updates on the organization mode will be published and advertised in due time. In any case, OVERLAY 2021 will be a no-fee event.

The increasing adoption of Artificial Intelligence techniques in safety-critical systems, employed in real world scenarios, requires the design of reliable, robust, and verifiable methodologies. Artificial Intelligence systems employed in such applications need to provide formal guarantees about their safety, increasing the need for a close interaction between the Artificial Intelligence and Formal Methods scientific communities. To witness this increasing need, tools and methodologies integrating Formal Methods and Artificial Intelligence solutions are getting more and more attention.

The workshop is the main official initiative supported by the OVERLAY group. The event aims at establishing a stable, long-term scientific forum on relevant topics connected to the relationships between Artificial Intelligence and Formal Methods, by providing a stimulating environment where researchers can discuss about opportunities and challenges at the border of the two areas.

Important goals of the workshop are

  1. to encourage the ongoing interaction between the formal methods and artificial intelligence communities,
  2. to identify innovative tools and methodologies, and
  3. to elicit a discussion on open issues and new challenges.

Topics of interest include (but are not limited to): automata theory automated reasoning automated planning and scheduling controller synthesis formal specification languages formal verification game theory hybrid and discrete systems logics in computer science reactive synthesis runtime verification and monitoring specification and verification of machine learning systems tools and applications

CAUSAL 2021: Workshop on Causal Reasoning and Explanation in Logic Programming, call for papers

September 20-27, 2021, virtual

Sophisticated causal reasoning has long been prevalent in human society and continues to have an undeniable impact on the advancement of science, technology, medicine, and other significant fields. From the development of ancient tools to modern roots of causal analysis in business and industry, reasoning about causality and having the ability to explain causal mechanisms enables us to identify how an outcome of interest came to be and gives insight into how to bring about, or even prevent, similar outcomes in future scenarios.

This workshop aims to bring together researchers and practitioners of logic programming with a dedicated focus on methods and trends emerging from the study of causality and explanation. We welcome the submission of papers on systems, tools, and applications of logic programming methods for causal reasoning and explanation. In particular, we encourage submissions presenting recent developments, including works in progress. The workshop will present the latest research and application developments in these areas and provide opportunities to discuss current and future research directions and relationships to other fields (e.g. Machine Learning, Diagnosis, Natural Language Processing and Understanding, Philosophy of Science). An important expected outcome of this workshop is to collect first-hand feedback from the ICLP community about the role and placement of causal reasoning and explanation in the landscape of modern computer theory as well as in the software industry.

NCMPL 2021: 3rd conference on Non-classical Modal and Predicate Logics, call for abstracts

November 23-26, 2021, Bochum, Germany

Modalities and predicates have since ancient time been central notions of logic. In the 20th century, various systems of non-classical logics have emerged, with applications in many disciplines like Computer Science, Linguistics, Mathematics, and Philosophy. This gave rise to the questions of a non-classical treatment of quantifiers and modalities and the accommodation of quantifiers and modalities in non-classical logics. In response, various modal and predicate variants of non-classical logics have been introduced and studied in the past decades.

NCMPL is a conference series solely dedicated to modal and predicate non-classical logics. The aim of the conference is to bring together researchers from various branches of non-classical logics, not only to present recent advances in their particular fields, but also to identify common problems and methods and foster the exchange of ideas between researchers from separate fields.

Topics of interest

The scope includes theoretical works on the above topics coming from all branches of formal logic (proof-theory, model theory, game theory, computational complexity, philosophical and historical aspects), as well as their applications in computer science, linguistics, philosophy, etc.

Strong papers on propositional logics can also be accepted, provided they relate to the themes in the main scope of the conference (e.g., the study of completions in algebraic semantics, infinitary logics, etc.).

Full versions of selected papers will be published in a special issue of an international peer-reviewed journal (to be specified).

Winter school LI 2022: 4th logic And interactions

January 24 - February 25, 2022, Marseille, France

We are delighted to announce Logic and Interactions 2022: a five week session at the CIRM in Luminy (Marseille, France), on logic and its interactions in mathematics and computer science, but also in the broader perspective of its transdisciplinary nature, with connexions to philosophy and linguistics. Two weeks will be organized as thematic schools targeted primarily at PhD students and non-specialist researchers. The other three will be workshops presenting the state of the art in specific areas.

As for previous sessions, we expect this event to offer a friendly venue not only for established specialists but also for students and young researchers as well as non-specialists. In addition to the thematic schools, each week will include introductory material. We encourage colleagues, and especially students and young researchers, to attend several weeks or even the full month, in order to make the most of this special occasion.

Practical information
We hope that the sanitary conditions will allow us to hold the event mainly in the pre-CoVid fashion: with participants attending physically at the CIRM. In any case, attending remotely will certainly be possible: the CIRM has invested a lot of efforts to make hybrid events the standard practice.

Accommodation at the CIRM will be available for participants attending physically. A limited number of fundings will be available to cover the accommodation and travel expenses, especially for students.

Pre-registrations will open soon. In the meantime, you can already save those weeks in your agenda.

More information is available on the school's web page.


Termination and Complexity Competition 2021, call for participation

Since the beginning of the millennium, many research groups developed tools for fully automated termination and complexity analysis.

After a tool demonstration at the 2003 Termination Workshop in Valencia, the community decided to start an annual termination competition to spur the development of tools and termination techniques.

The termination and complexity competition focuses on automated termination and complexity analysis for all kinds of programming paradigms, including categories for term rewriting, imperative programming, logic programming, and functional programming. In all categories, we also welcome the participation of tools providing certifiable proofs. The goal of the termination and complexity competition is to demonstrate the power of the leading tools in each of these areas.

The competition will be affiliated to CADE 2021. The competition will be run on the StarExec platform shortly before CADE.

We strongly encourage all developers of termination and complexity analysis tools to participate in the competition. We also welcome the submission of termination and complexity problems, especially problems that come from applications.

A category is only run in the competition if there are at least 2 participants and at least 40 examples for this category in the underlying termination problem data base. If there is no category that is convenient for your tool, you can contact the organizers, since other categories can be considered as well if enough participants are guaranteed.

Important dates

For further information, we refer to the website of the termination and complexity competition.

PhD position on program verification in Coq

There is an opening for a 3-year PhD position at University of Lille, France. The successful applicant will be funded -- including salary and (international) conference travel -- through a new French-German ANR-funded project. There will also be an opportunity to collaborate with a research team in Japan.

Lille is at the heart of Europe: 45 minutes from Bruxelles, 1 hour from Paris, 1 hour and half from London. This is an important university hub that hosts the annual International Cybersecurity Forum (FIC).

The start date is September 1st, but might possibly be postponed to October 1st.

The PhD position is about the formal proof in Coq for shallow-embedded imperative programs and their compilation into C (more details below).

Interested students should meet the following requirements:

If you are interested in applying for this opportunity please begin by contacting Gilles Grimaud, Samuel Hym and David Nowak. as soon as possible with the following information:

The topic of this PhD offer is the formal proof in Coq for shallow-embedded imperative programs and their compilation into C. More precisely, the objective is to conceive and develop formal tools to simplify code writing and proof of system software for low-end devices.

The Coq proof assistant allows to prove properties of programs. Its language, called Gallina, is purely functional. In the Pip project, we have considered a monadic subset of C-like Gallina enough to formally write an OS kernel.

A first objective of this PhD is to extend the monadic subset in order to include further imperative features (such as loops, references or exceptions) that will simplify code writing and proof of system software for low-end devices. For security properties the monadic Hoare logic used for Pip will have to be extended to deal with the new imperative features. For functional properties, there are two possible directions: either use the monadic Hoare logic or monadic equational reasoning as developed in Monae. The relation with FreeSpec should also be investigated.

A second objective is to automatically translate programs written in this monadic subset into an AST of the CompCert C verified compiler and to prove formally that this translation is correct, in the sense that properties proved on the monadic subset are also true of the generated C code.

PhD position in higher-order rewriting and program equivalence at Radboud University Nijmegen

There is currently a PhD position available at Radboud University Nijmegen (the Netherlands) in the topic Higher-order Term Rewriting for Program Equivalence. The position is for four years, and comes with a competitive salary and very attractive employment conditions.

Interested students who either already hold a Masters' degree in computer science, mathematics, or a related area, or who will complete such a degree before September, are encouraged to apply. The initial application deadline is 20 June, but will be extended if no suitable candidate is found by that time.

The project
As a PhD candidate, you will conduct research into higher-order term rewriting systems with logical constraints. This project brings together two different areas of theoretical computer science: higher-order term rewriting and program equivalence analysis.

Term rewriting is a formal system that can be used to specify algorithms. Its simple, rigorous definition makes it very suitable for formal analysis, and as a result, its properties are well studied. Higher-order term rewriting extends standard term rewriting with anonymous functions and binders as in the lambda-calculus, thus providing a highly liberal class of systems.

Term rewriting can be combined with a logical theory and logical constraints; for example, integer numbers and conditions such as x >= 1 /\ y != x. With this approach, it Is possible to model programs in common programming languages; higher-order term rewriting systems in particular offer a natural model to analyse functional and object-oriented programming languages.

Program equivalence analysis is the study of whether two systems of program code have the same result, given the same input. This is a challenging field with many applications both in business practice and in other areas of computing science.

In this project, your task will be to develop techniques for program equivalence analysis, by analysing in particular higher-order term rewriting systems with logical constraints, which encode realistic programs. The majority of the project is the development of theory, but since it is a goal to develop automatable techniques, you will also implement some of your techniques in a prototype analysis tool.

You will be supervised by Dr Cynthia Kop. If you wish to learn more, feel free to send an e-mail.

Work environment
Strategically located in Europe, Radboud University is one of the leading academic communities in the Netherlands. It is a place with a personal touch, where top-notch education and research take place on a beautiful green campus, in modern buildings with state-of-the-art facilities.

The position is available in the Software Science group of the Institute for Computing and Information Sciences (iCIS) at Radboud University. Research at iCIS focuses on software science, digital security and data science. During recent evaluations, iCIS has been consistently ranked as the No. 1 Computing Science department in the Netherlands. Evaluation committees praised our flat and open organisational structure, our ability to attract external funding, our strong ties to other disciplines, and our solid contacts with government and industrial partners. The Software Science group is well known for its contributions to the mathematical foundations of software, formal methods, and functional programming.

PhD position on Embedded Systems Verification at University of Twente, Netherlands

We are looking for a PhD candidate for a 4-year project on Formal Methods for Embedded Systems, as part of SAVES (ScAlable Verification of industrial Embedded control Systems), a collaboration with the University of Münster (WWU Münster). You will be working on the SAVES project, carried out in collaboration with prof. dr. Paula Herber (University of Twente / WWU Münster).

The overall goal of SAVES is to investigate methods and tools to establish correctness of embedded systems. With trends such as Industry 4.0, the internet of things, and autonomous driving, the complexity of embedded systems is steadily increasing. A prerequisite to ensure the correct functioning of industrial embedded systems under all circumstances is a clear understanding of the models and languages that are used in the development process. Formal methods provide a basis to make the development process systematic, well-defined, and automated. However, for many industrially relevant languages and models, the semantics are only informally defined. Together with the limited scalability of formal design and verification techniques, this makes the formal verification of industrial embedded control systems a difficult challenge, which can not be solved satisfactory with currently available methods and tools. At the same time, we see that in the area of deductive program verification, powerful techniques and tools have been developed to reason about software with unbounded parameters, for example the VerCors tool suite. In this project, we will extend these techniques with concepts to cope with heterogeneity, concurrency, and real-time to make them suitable for industrial embedded systems.

The PhD candidate hired at the University of Twente will be supervised by Marieke Huisman and Paula Herber and will work on extensions of the methods and tools developed in the FMT group for embedded systems, in close collaboration with the Embedded Systems group in Münster.

Industry researchers and engineer sought for new ATP/ITP project, Edinburgh UK

A Gentle Invitation into Theorem Proving towards Formal Hardware Verification

What is the nature of human reasoning and problem solving? How can machines exploit the known skills of problems solving to solve new problems automatically? Is it possible to work out general patterns of discovery and reasoning, such that machines can develop new methods and systems? We try to answer these problems and shrink the gap between machine learning and human wisdom.

Mathematical discovery and reasoning is considered the most creative activity of human wisdom. Mathematicians have been investigating the nature of human reasoning and problem solving since classical Greece. Even if the development of interactive theorem provers provides rigorous tools for people to formalise mathematics and to verify hardware and software designs, there is still a big gap between human reasoning and mechanical theorem proving: precious human intelligence is wasted on proving tedious and trivial lemmas, which are indispensable for machines to check the correctness and the integrity of a proof, but are quite obvious for well-educated mathematicians or computer scientists. Even worse, it is hard to recover the original intentions by reading these mechanical proofs.

During the first year of this project, we will focus on developing an automated theorem prover towards human reasoning. Except the automation of proof strategies and skills, the main planned innovation is: deriving theories automatically. We want to investigate and implement such a mechanism: to generate conjectures from cases, concepts, proofs, and known theorems, then produce automatically human readable and machine checkable proofs. We also plan to design and implement the mechanism to discover and exploit morphisms between algebraic structures, so as to simplify proofs by making use of abstract domains. It doesn't mean that we don't need human interference; on the contrary, we want to make use of human experience whenever possible --- machines will learn from humans when, for example, they are stuck, the computation diverges, the solution space is too big, and so on. We believe that human skills of problem solving will enable machines to think like us and to make plausible reasoning at the end.

We will soon open the following positions for this project. There will be a competitive salary and benefits package in line with top tier industrial R&D positions in UK.

Work Location: Edinburgh UK

PhD student position in enabling reactive synthesis, Goeteborg (Sweden)

Open PhD position in the department of Computer Science and Engineering at the University of Gothenburg/Chalmers, Sweden. The student will work on the project "Enabling Reactive Synthesis through Runtime Verification? with Professor Nir Piterman. The student will join a team supported by an ERC Consolidator grant and the Swedish research council (vetenskapsrådet (VR)).

Research scope: formal methods, reactive synthesis, runtime verification, automata, games, temporal logics

Apply here.

Read more what it would be like here

The successful candidate will work on the project ?Enabling Reactive Synthesis through Runtime Verification?. Reactive synthesis - automatic production of programs from high-level descriptions of their desired behavior - is emerging as a viable tool for the development of robots and reactive software. In high level, this is like telling a robot what you would like it to do and automatically planning how to do it. Runtime verification is an approach for following programs through their execution to ensure that they work correctly. The project will improve the capabilities of reactive synthesis techniques through exploiting methods that are used for runtime verification. This will include both theoretical and practical contributions.

More concretely, the work will include the study of temporal logic, automata, and two player games. Temporal logic is used for describing in a high level the required behavior of a program, automata are used as an algorithmic tool for manipulation of logic formulae, and two-player games enable to consider strategies and programs. We will study these formalisms, analyze their properties, devise algorithms to manipulate and translate between them, as well as implement tools that will show the applicability of the developed techniques.

The aim of the doctoral (third-cycle) education is to acquire the knowledge and skills necessary to conduct independent research within computer science, and to contribute to the development of knowledge by writing a scholarly thesis.

PhD (third-cycle) education is through a fixed-term employment contract for 5 years. During these 5 years, most of the student?s time will be devoted to their research. They will also be assisting the department?s education by working 20% of their time on a teaching or supporting role. The 20% support component may be concentrated in certain parts of the year according to department?s needs (in consultation with the student). In addition, the student will have to undertake 60 Higher Education Credits in courses enriching their knowledge in computer science, supporting their research, and gaining general (scientific) skills.
