On the future publication venue for CADE

Sophie Tourret
CADE trustee
Linked to poor publication experiences (such as described here), the choice of a publication venue for CADE has been a recurrent topic of discussion among the trustees of CADE. Our discussions have left us with two viable options at present, each with their own pros and cons: LNCS and LIPIcs. In the near future, we will ask for the opinion of the CADE community on this topic via a poll, before finally making a decision. In the meantime, Renate and Marijn have summarised the main arguments for choosing each venue below.

Arguments for LNCS Conference Proceedings

Renate Schmidt
CADE trustee

➕ Springer is recognised as a long-standing, reputable publisher and publishing with LNCS/Springer is a sign of quality in a lot of disciplines.

➕ This is important for how publications are evaluated in grant application panels, national research evaluation panels, and University promotion/appointment panels. These panels are broadly composed and may not include people who have heard of CADE, IJCAR, LIPIcs or Schloss Dagstuhl. But they will have heard of Springer. The difference in scale is evident from the venue statistics provided by DBLP:

On only two conferences with proceedings published by Schloss Dagstuhl are included in the list of Best Computer Science Conferences (at positions 852 and 858) (Source: here)

➕ Springer provides faster indexing and a larger number of indexing services than LIPIcs:

(Source: here)

➖ The costs associated with these services need to be covered and are paid for through library subscriptions and Gold Access charges.

➕ Our current deal for Springer Open/Gold Access for conference proceedings of CADE, IJCAR, TABLEAUX and FroCoS is moderately priced (200 Euros) and includes sponsorship for CADE and IJCAR which amounts to 10 free papers. The costs are a bit higher than for LIPIcs but not significantly so and a fraction of the costs of individual author Open Access charges.

➕ The Green Access option would remove author publication costs. Green Access means that authors are allowed to make their papers available via their home pages or their institution's repositories. For many authors Green Access is enough.

➕ Minimal editorial work for PC Chairs.

➖ Type-setting: It is unfortunate that the author guideline/style files don't seem to agree with the style files that are eventually used in production. Some authors understandably get very worked up about this, since they have put so much effort in the preparation of the final versions of there papers. But all journals do type-setting that will make some changes which are normally cosmetic and small. If bugs are introduced during typesetting then these are identified by the authors and fed back to the publisher. I don't have problems with the type-setting in LNCS. An experience with the publishing process for a conference in another discipline (not LIPIcs) has been an eye opener how well-organised and hands-off Springer type-setting and copy-editing is in actual fact. Improving instructions and reducing type-setting changes that depart from author style files is however something we should continue to raise with Springer.

➕ It will be unfair on our communities to be disadvantaged while we all use our energy to make sure LIPIcs is recognized in committees. These things can take many years, generations even, to achieve. LIPIcs is still small, even in Computer Science.

➕ Some of our main competitor conferences (CAV, TACAS) continue to publish with Springer. It might put CADE at a disadvantage if we move to LIPIcs while they remain with Springer.

➕ It would be awkward if CADE moves to LIPIcs, but IJCAR stays with Springer. Similar, it would be awkward if CADE and IJCAR both move to LIPIcs, but FroCoS and Tableaux stay with Springer. So a move would only be feasible if CADE, IJCAR, FroCoS, and Tableaux all move to LIPIcs. But it is not clear whether LIPIcs would agree with that.

All in all, while we can secure a good Open Access Deal with Springer and since rankings, impact factors and publisher visibility/reputability play such a large role in the way that money is allocated, who gets tenure, who is promoted, etc, having LIPIcs publications will not be as beneficial as having Springer publications. Although such criteria should not play a role in evaluations, in practice they do. It is our responsibility to think of our young researchers, people without tenure and active researchers applying for grants and do what is best for them and the field.

Arguments for LIPIcs Conference Proceedings

Marijn Heule
CADE trustee

LIPIcs is a high-quality publisher of conference proceedings. It has many advantages compared to the status quo. Below are some arguments in favor of LIPIcs.

➕ All articles published by LIPIcs are Open Access.

➕ The interaction with authors and conference chairs is professional and efficient.

➕ The same style file is used for submission and publishing. Authors know exactly how their article will look like when it will be published.

➕ Opt-in changes. The LIPIcs typesetters will propose changes if they encounter issues. However, it is up to the authors to decide which of these changes to apply. If authors don't respond, then the article will be published as submitted. This is a big contrast to Springer, which makes seemingly random modifications that authors need to detect and report.

➕ The cost per article is 60 euro, which is substantially cheaper compared to alternatives.

➕ LIPIcs focuses on quality, while Springer focuses on quantity and cheap labor.

➖ LIPIcs does not produce a HTML version of the paper, which is part of the reason why they can offer a lower price. LIPIcs assumes that papers are on average 20 pages, including bibliography and appendices. If the average page count is higher (which is not the case for CADE/IJCAR), then a slightly higher price needs to be paid.

➕ The LIPIcs timeline is somewhat shorter compared to other publishers. This provides more flexibility for the reviewing window. It also ensures that the proceedings are available during the conference (which is not always the case with Springer).

➕ Related conferences have been moving to LIPIcs in recent years. Examples are FSCD (2016), ITP (2019), CP (2021), and SAT (2022). Note that various conferences that are ranked higher than CADE (according to Best Computer Science Conferences) moved to LIPIcs. For example, CADE is ranked 824 while SAT is ranked 441 and CP is ranked 557.

It's disheartening to observe how Springer shifted its operational strategy to prioritize profit over quality. This was markedly evident when they outsourced typesetting and correction tasks to a cheap-labor country. Moverover, Springer expanded the LNCS proceedings indiscriminately, welcoming conferences of all tiers that are willing to put their papers behind the paywall. This strategy, aimed at augmenting revenue streams from universities and funding agencies, has eroded the prestige once associated with LNCS in particular and Springer in general. In stark contrast stands LIPIcs, a non-profit publisher that champions uncompromising quality standards and a staunch commitment to Open Access. Switching to LIPIcs enhances the author experience and elevates the quality of the proceedings. It's time to align with our related conferences in embracing publishers like LIPIcs, who are shaping the future of academic publishing through their integrity and dedication to accessibility and quality.

Nominees and Results of the CADE Trustee Elections

Philipp Rümmer
Secretary of CADE Inc.

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, Bill McCune, and Skolem Award selection committee, instituting new awards, etc.

The members of the board of trustees until the 2023 elections were:

The terms of the elected trustees Marijn Heule, Andrew Reynolds, and Renate Schmidt ended. The term of office of Brigitte Pientka as CADE-29 programme chair ended after the CADE conference, and Christoph Benzmüller is joining the board of trustees as IJCAR 2024 program co-chair.

In the 2023 elections, three new trustees had to be elected.

The following candidates were nominated and their statements, in alphabetical order, are below:

The election was carried out using the Condorcet Internet Voting Service (CIVS), and the Condorcet completion Minimax-PM. Participants of the last three CADE/IJCAR conferences (who paid registration fees at at least one of the conferences) were invited to vote, and a total of 301 ballots were sent out on September 5. By September 25, 79 CADE members had voted through CIVS, which translates to a participation rate of 26.2% (as compared to 26.7% in 2022, 26.7% in 2021, 34.5% in 2019, 21.1% in 2018, 9.1% in 2017, 11.2% in 2016).

The results of the election can be viewed on CIVS:.

  1. Jasmin Blanchette: Condorcet winner: wins contests with all other choices;
  2. Carsten Fuhs: loses to Jasmin Blanchette by 50–24;
  3. Renate Schmidt: loses to Jasmin Blanchette by 49–22, loses to Carsten Fuhs by 44–26;
  4. Uwe Waldmann: loses to Jasmin Blanchette by 52–23, loses to Renate Schmidt by 37–34.

The three candidates elected are Jasmin Blanchette, Carsten Fuhs, and Renate Schmidt.

The new board of trustees is therefore:

On behalf of CADE Inc., I would like to thank Marijn Heule and Andrew Reynolds for their service on the board of trustees since 2017. I would like to congratulate Jasmin Blanchette and Carsten Fuhs, who will join the board as new elected trustees, and Renate Schmidt on being reelected. Finally, I would also like to thank Uwe Waldmann for running in the elections.

Nominee statement of Jasmin Blanchette

My research focuses on the automation of higher-order logic. I work mainly on the proof assistant Isabelle/HOL and the automatic theorem prover Zipperposition. My goal is to make proof assistants less laborious to use by improving their build-in automation and by integrating automatic provers.

I have a history of service in the community. I have chaired IJCAR, CPP (Certified Programs and Proofs), ITP (Interactive Theorem Proving), and TAP (Tests and Proofs). I have also served as a CADE trustee from 2016 to 2019 and, ex officio, in 2021 and 2022. I have attended most installments of CADE and IJCAR since 2009 and consider it my home conference.

As a CADE trustee, I would work towards ensuring that CADE and IJCAR remain open to a wide range of deduction techniques and feature a healthy mixture of theory and practice. I believe this is best achieved by having at least two program chairs who have complementary backgrounds.

I would also argue in favor of systematizing the CADE practices. Program chairs should have clear guidelines and templates they can work with. Important matters such as the use (or not) of rebuttals should be settled by the board of trustee, instead of being left to each year's chairs to decide. A permanent repository of knowledge for use by program chairs should be set up, containing instructions about processes, template emails, etc.

Finally, we must increase the conference's impact and prestige. According to the CORE index (which has an impact on many researchers' careers), CADE and IJCAR are ranked A ("excellent conference"). There are specific measures we could take to obtain the top grade, A* ("flagship conference"). I would be in favor of doing what it takes to achieve this.

Nominee statement of Carsten Fuhs

I am honoured by the nomination to serve on the CADE board of trustees. CADE and IJCAR are among the main conferences that I regularly attend. I have published at both conferences, been on the PC of CADE-29 in 2023, and served on the expert committees for the Bill McCune PhD award since its inception in 2020.

My own research is firmly rooted in automated reasoning and deduction, with push-button termination analysis, inference of complexity bounds and checking program equivalence in various computation formalisms as my main foci. Thus, my research connects the use of methods and tools in automated deduction (e.g., SAT and SMT solvers) with applications in program analysis. I am one of the main developers of the program verification tool AProVE.

I am currently serving as Publicity Chair in the Steering Committee of the neighbouring International Conference on Formal Structures for Computation and Deduction (FSCD). I think that the co-location of CADE and FSCD in Rome in 2023 with 24 joint registrations has been a big success: it has allowed for cross-fertilisation between our closely related communities and for reducing the need for frequent long-distance travel with its downsides on individual level in the short term and on planetary level in the medium term. Therefore, I would advocate for further co-location of CADE with related conferences such as FSCD or CAV in the coming years.

In a similar vein, I strongly believe that the option of hybrid participation and also presentation as implemented at CADE/FSCD in Rome should be upheld. This lowers the entry barrier for participants and authors who cannot spend financial and time resources on a week far away from home obligations. Reasons may include being a parent or carer, living in the developing world, being a taught student considering going into research, or simply being interested only in specific presentations.

There have been concerns that the online option of a hybrid event might dissuade many professional researchers from attending in person. However, the lively in-person interaction at CADE/FSCD in 2023 seems to indicate that these concerns are unfounded. At the same time, an observation at FSCD 2023 was that 10% of the presentations would not have been possible without the option for remote presentation. This shows that a hybrid event can increase the quality of the programme and broaden the reach of the conference without detrimental effects on the overall conference experience for in-person participants.

In regards to the publication model of CADE, I consider making the conference proceedings available as open-access publications, as in 2023, to be the right way forward. To keep the financial entry barrier for authors low and to ensure that the quality of submission remains the sole criterion for publication, I think that it is important that funding by CADE for authors to cover open-access fees should continue to be available as needed. Here a sensible balance needs to be struck between attendance fees paid by all participants and open-access publication fees paid by the authors.

Finally, I am in favour of initiatives that support young researchers who are trying to establish themselves in the CADE community and in academia. This includes the Woody Bledsoe Student Travel Award for making attendance of CADE possible for students and the Bill McCune PhD award for distinguishing the contributions of a recent PhD thesis in automated reasoning, thus helping to kickstart the academic career of a promising researcher in the CADE community towards a permanent position.

Nominee statement of Renate Schmidt

As a previous member of the CADE Board of Trustees I appreciate its importance in securing good conference locations, appointing PC Chairs, constituting award committees, ensuring the success of various other activities in our area and providing leadership and representation for the area of automated reasoning. I have experience in chairing the CADE, FroCoS and TABLEAUX conferences and am PC-CoChair of IJCAR 2024. I am also founding organiser of the PAAR workshop series and am Editorial Board member/Associate Editor of the Journal of Automated Reasoning, the Artificial Intelligence Journal and the Journal of Artificial Intelligence Research.

This varied experience gives me a broad perspective on issues and concerns in our community and will allow me to continue be a strong advocate for the interests of automated deduction, its future and integrity in all our processes. I would be honoured to serve on the CADE Board of Trustees for another term.

My background: My main research involves the development and theoretical analysis of reasoning methodologies and automated reasoning tools as well as applying these in areas such as artificial intelligence, knowledge representation, agent-based systems and mathematics. At present a very strong focus of my work is the development of tools 1) for forgetting, content extraction, abductive learning and query answering in the context of ontology-based languages, and 2) for tableau synthesis, uniform interpolation and automated correspondence theory in the context of non-classical logics.

Nominee statement of Uwe Waldmann

I feel honored to be nominated for the CADE Board of Trustees. Working mainly on saturation-based proof calculi and systems, I consider CADE my home conference. I had my first CADE paper in 1996, visited almost every CADE since 1990, and participated in 8 of the last 11 CADE and IJCAR program committees.

I am generally happy with the development of CADE in the last decades. The regular alternation between CADE and IJCAR, the co-locations with other conferences, and the large range of workshops are important to foster cooperations with researchers from neighboring communities. Measures to support and promote young scientists help to keep the field of automated deduction alive and should be continued. To remain the leading conference in our field, the spectrum of possible topics for CADE must stay broad and theoretical papers, practical papers, and application papers must be equally welcome. In order to attract scientists from outside Europe, it is also important that CADE takes place on other continents on a regular basis

There seems to be a general consensus that moving to open access CADE proceedings was the right decision, both because it improves the accessibility of our research and because some funding agencies insist on it. When we look at the details, however, we encounter conflicting interests. While for some authors the visibility of the publication and the publisher's prestige are paramount, others place a greater emphasis on low publication fees and would prefer do not feel screwed by the publisher's copy editors. We must find a reasonable compromise in this matter.

2 PostDocs (3y, 2y) LoDEx/ deontic explanation/ defeasible reasoning, Bochum / Luxembourg / Vienna

The research group Logic in Philosophy and Artificial Intelligence (Christian Straßer, Ruhr-University Bochum) has an opening for two PostDoc-positions (3y and 2y). Deadline: 30. October 2023.

Position 1 (3y) is embedded in the LoDEx project (Logical methods for Deontic Explanations), a joint project between the Ruhr-University Bochum (PI: Christian Straßer), the University of Luxembourg (PI: Leon van der Torre) and the TU Vienna (PI: Agata Ciabattoni).

Position 2 (2y) is funded by the Ruhr University Bochum.

Description: Position 1 (LoDEx). ANR: 2461.
This position is a three-year, 100%-funded PostDoc position (TV-L 13), starting February 2024.

The candidate will be working as a member of the WEAVE project “Logical methods for Deontic Explanations” (LoDEx). The project’s general aim is to develop formal frameworks for generating explanations in the context of ethical and legal reasoning. These "deontic explanations" facilitate our comprehension of the underlying reasons for the application of specific norms within a particular context, illuminating why adherence to these norms is crucial.

The PostDoc position focuses on the use of formal argumentation for the modeling of deontic explanations. Such a model comes with many challenges. One is that in order to be more perspicuous and convincing, explanations should take into account what the explainee believes and values, i.e., their epistemic and axiologic horizon. Another challenge is the contrastive nature of explanations, since why-questions are often framed contrastively ('Why should I do A rather than B?'). Formal argumentation offers a good basis for modeling explanatory exchanges, e.g., in terms of dialogues. The candidate will also interact with a PhD student working on applications of deontic explanations to bioethical problems.

The candidate should have familiarity with either of the following (and ideally several):

Description: Position 2. Defeasible Reasoning. ANR: 2394.
This position is a two-year, 100%-funded PostDoc position (TV-L 13), starting February 2024.

The candidate will be working on formal models of defeasible reasoning, in particular those based on nonmonotonic logic and formal argumentation.

Possible areas of specialization include:

The position comes with a teaching requirement, namely 2 courses per teaching term.

Multiple theorem proving PhD/postdoc positions at LMU München

Prof. Jasmin Blanchette is looking for PhD students (4 years) and postdoctoral researchers (3 years) who will work at the Ludwig-Maximilians-Universität in Munich, Germany. They will be hosted by the Chair of Theoretical Computer Science and Theorem Proving led by Prof. Jasmin Blanchette. The work will be supervised by Blanchette together with external experts and will be funded by the ERC project Nekoka.

Proof assistants (also called interactive theorem provers) have a long history of being very tedious to use. The situation has improved markedly in the past 10–15 years with the integration of first-order automatic theorem provers that increase proof automation. And recently, there have been exciting developments for more expressive logics, with the emergence of automatic provers based on optimized higher-order proof calculi. The Nekoka project’s aim is to make two of these calculi, higher-order SMT and lambda-superposition, a great fit for logical problems emerging from the verification of software and mathematics.

Nekoka is the logical successor of the Matryoshka project, which led to the development of lambda-superposition and its implementation in the E and Zipperposition provers. The Nekoka topics range from extending higher-order SMT and lambda-superposition to integrating them in general-purpose proof assistants (e.g., Isabelle, Lean) and software verification platforms (e.g., F*, TLA+ Proof System) to using the resulting automation in case studies related to quantum information theory and a big data framework.

For the postdoc positions, we are also interested in applicants who have their own research agenda compatible with the general aims of Nekoka.

The positions are categorized as TV-L E13 according to the German salary scale. The starting date is flexible. Please contact Jasmin Blanchette for more information or if you want to apply. Applications should include

There is no application deadline. Applications will be processed continuously until the positions are filled.

PhD/postdoc vacancy on the verification of cryptographic protocols at Aarhus University

Bas Spitters is looking for a strong PhD-candidate at Aarhus University (DK). There may be possibilities for a postdoc position. Please contact him for more information.

The PhD positions include full tuition waiver and a very competitive scholarship. Aarhus University provides international students with a safe and stable environment, a high standard of living and a wealth of social opportunities. Besides having an excellent reputation that enables our PhD graduates to find outstanding employment prospects, Aarhus University offers attractive working conditions, research support and campus resources. See here and here for more information.

This project is supported by the Danish DIREC research center. It is a collaboration between Aarhus University, the Alexandra Institute and Concordium ApS. The aim of the project is work towards secure implementations of Blockchain Voting Governance Protocols and Internet Voting Protocols.

Voting and blockchains are intimately connected. Voting is used in blockchains for consensus, governance, and decentralized organizations. Conversely, elections are based on trust, which means that election systems ideally should be based on algorithms and data structures that are already trusted. Blockchains provide such a technology. They provide a trusted bulletin board, which can be used as part of some voting protocols. Moreover, voting crucially depends on establishing the identity of the voter to avoid fraud and to establish eligibility verifiability.

Decades of research in voting protocols have shown how difficult it is to combine the privacy of the vote with the auditability of the election outcome. It is easy to achieve one without the other, but hard to combine both into one protocol. Thus, the topic of this research proposal is to investigate voting protocols and their relation to blockchains.

The team will work on (machine-checked) security proofs of these protocols and their implementations, for instance using tools such as ConCert and SSProve which are built on the Coq proof assistant.
