## CFP for Certified Programs and Proofs (CPP 2020) ## Certified Programs and Proofs (CPP) is an international conference on practical and theoretical topics in all areas that consider certification as an essential paradigm for their work. Certification here means formal, mechanized verification of some sort, preferably with the production of independently checkable certificates. CPP spans areas of computer science, mathematics, logic, and education. CPP 2020 will be held on 20-21 January 2020 in New Orleans, Louisiana, United States and will be co-located with POPL 2020. CPP 2020 is sponsored by ACM SIGPLAN, in cooperation with ACM SIGLOG.

Abstract and submission deadlines are tight and there will be **no extensions**. ### Topics of Interest We welcome submissions in research areas related to formal certification of programs and proofs. The following is a non-exhaustive list of topics of interests to CPP: - certified or certifying programming, compilation, linking, OS kernels, runtime systems, and security monitors; - certified mathematical libraries and mathematical theorems; - proof assistants (e.g, ACL2, Agda, Coq, Dafny, F*, HOL, HOL-Light, Idris, Isabelle, Lean, Mizar, Nuprl, PVS, etc) - new languages and tools for certified programming; - program analysis, program verification, and program synthesis; - program logics, type systems, and semantics for certified code; - logics for certifying concurrent and distributed systems; - mechanized metatheory, formalized programming language semantics, and logical frameworks; - higher-order logics, dependent type theory, proof theory, logical systems, separation logics, and logics for security; - verification of correctness and security properties; - formally verified blockchains and smart contracts; - certificates for decision procedures, including linear algebra, polynomial systems, SAT, SMT, and unification in algebras of interest; - certificates for semi-decision procedures, including equality, first-order logic, and higher-order unification; - certificates for program termination; - formal models of computation; - mechanized (un)decidability and computational complexity proofs; - user interfaces for proof assistants and theorem provers; - original formal proofs of known results in math or computer science; - teaching mathematics and computer science with proof assistants. ### Program Committee Members - Jasmin Christian Blanchette (VU Amsterdam, Netherlands -- co-chair) - Catalin Hritcu (Inria Paris, France -- co-chair) - Nada Amin (Harvard University - USA) - Jesús María Aransay Azofra (Universidad de La Rioja - Spain) - Mauricio Ayala-Rincon (Universidade de Brasilia - Brazil) - Liron Cohen (Cornell University - USA) - Dominique Devriese (Vrije Universiteit Brussel - Belgium) - Jean-Christophe Filliâtre (CNRS - France) - Adam Grabowski (University of Bialystok - Poland) - Warren Hunt (University of Texas - USA) - Ori Lahav (Tel Aviv University - Israel) - Peter Lammich (The University of Manchester - UK) - Dominique Larchey-Wendling (Univ. de Lorraine, CNRS, LORIA - France) - Hongjin Liang (Nanjing University - China) - Assia Mahboubi (Inria and VU Amsterdam - France) - Cesar Munoz (NASA - USA) - Vivek Nigam (fortiss GmbH - Germany) - Benjamin Pierce (University of Pennsylvania - USA) - Vincent Rahli (University of Luxembourg, SnT - Luxembourg) - Christine Rizkallah (UNSW Sydney - Australia) - Ilya Sergey (Yale-NUS College and National University of Singapore) - Kathrin Stark (Saarland University - Germany) - Nikhil Swamy (Microsoft Research - USA) - Nicolas Tabareau (Inria - France) - Dmitriy Traytel (ETH Zürich - Switzerland) - Floris van Doorn (University of Pittsburgh - USA) - Akihisa Yamada (National Institute of Informatics - Japan) - Roberto Zunino (University of Trento - Italy) ### Submission Guidelines Prior to the paper submission deadline, the authors should upload their **anonymized** paper in PDF format through the HotCRP system at https://cpp2020.hotcrp.com Submissions must be written in English and provide sufficient detail to allow the program committee to assess the merits of the paper. Submitted papers must be formatted following the [ACM SIGPLAN Proceedings](http://www.sigplan.org/Resources/Author/) format using the `acmart` style with the `sigplan` option, which provides a two-column style, using 10 point font for the main text, and a header for double blind review submission, i.e., ``` \documentclass[sigplan,10pt,review]{acmart}\settopmatter{printfolios=true,printccs=false,printacmref=false} ``` Submitted papers should not exceed 12 pages, including tables and figures, but **excluding bibliography and clearly marked appendices**. The paper should be self contained without the appendices. Shorter papers are welcome and will be given equal consideration. Papers not conforming to the requirements concerning format and maximum length may be rejected without further consideration. CPP 2020 will employ a **lightweight double-blind reviewing process**. To facilitate this, submitted papers must adhere to two rules: 1. author names and institutions must be omitted, and 2. references to authors' own related work should be in the third person (e.g., not "We build on our previous work …" but rather “We build on the work of …"). The purpose of this process is to help the PC and external reviewers come to an initial judgment about the paper without bias, not to make it impossible for them to discover the authors if they were to try. Nothing should be done in the name of anonymity that weakens the submission or makes the job of reviewing the paper more difficult. In particular, important background references should not be omitted or anonymized. In addition, authors are free to disseminate their ideas or draft versions of their paper as usual. For example, authors may post drafts of their papers on the web or give talks on their research ideas. POPL has answers for frequently asked questions addressing many common concerns: https://popl20.sigplan.org/track/POPL-2020-Research-Papers#Submission-and-Re... We encourage authors to provide any supplementary material that is required to support the claims made in the paper, such as proof scripts or experimental data. These materials must be uploaded at submission time, as an archive, not via a URL. Two forms of supplementary material may be submitted: - Anonymous supplementary material is available to the reviewers before they submit their first-draft reviews. - Non-anonymous supplementary material is available to the reviewers after they have submitted their first-draft reviews and learned the identity of the authors. Use the anonymous form whenever possible, so that the materials can be taken into account from the beginning of the reviewing process. Submitted papers must adhere to the SIGPLAN Republication Policy and the ACM Policy on Plagiarism. Concurrent submissions to other conferences, journals, workshops with proceedings, or similar forums of publication are not allowed. The PC chairs should be informed of closely related work submitted to a conference or journal in advance of submission. One author of each accepted paper is expected to present it at the conference. ### Publication, copyright, and open access The CPP proceedings will be published by the ACM, and authors of accepted papers will be required to choose one of the following publication options: 1. Author retains copyright of the work and grants ACM **a non-exclusive permission-to-publish license** and, optionally, licenses the work under a Creative Commons license; 2. Author retains copyright of the work and grants ACM **an exclusive permission-to-publish license**; 3. Author **transfers copyright** of the work to ACM. For authors who can afford it, we recommend option 1, which will make the paper **Gold Open Access**, and also encourage such authors to license their work under the CC-BY license. ACM will charge you an article processing fee for this option (currently, US$700), which you have to pay directly with the ACM. For everyone else, we recommend option 2, which is free and allows you to achieve **Green Open Access**, by uploading a pre-print of your paper to a repository that guarantees permanent archival such as arXiv or HAL. This is anyway a good idea for **timely dissemination** even if you chose option 1. Ensuring timely dissemination is particularly important for this edition, since, because of the very tight schedule, the official proceedings might not be available in time for CPP. The official CPP 2020 proceedings will also be available via SIGPLAN OpenTOC. For ACM's take on this, see their Copyright Policy and Author Rights. ### Contact For any questions please contact the two PC chairs: Catalin Hritcu <catalin.hritcu@gmail.com<mailto:catalin.hritcu@gmail.com>>, Jasmin Christian Blanchette <j.c.blanchette@vu.nl<mailto:j.c.blanchette@vu.nl>>
