Certified Programs and Proofs (CPP) is an international forum on theoretical and practical topics in all areas, including computer science, mathematics, and education, that consider certification as an essential paradigm for their work. Certification here means formal, mechanized verification of some sort, preferably with production of independently checkable certificates. In 2019, CPP will be colocated with Principles of Programming Languages (POPL) in Cascais/Lisbon, Portugal. Important Dates (AoE, UTC-12h) Abstract Deadline: Wednesday, 11 October 2018 Paper Submission Deadline: Wednesday, 18 October 2018 Author Notification: Wednesday, 22 November 2018 Conference dates: 14 January - 15 January 2019 Topics of interest We welcome submissions in research areas related to formal certification of programs and proofs. The following is a suggested list of topics of interests to CPP. This is a non-exhaustive list and should be read as a guideline rather than a requirement. - certified or certifying programming, compilation, linking, OS kernels, runtime systems, and security monitors; - program logics, type systems, and semantics for certified code; - certified decision procedures, mathematical libraries, and mathematical theorems; - proof assistants and proof theory; - new languages and tools for certified programming; - program analysis, program verification, and proof-carrying code; - certified secure protocols and transactions; - 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; - logics for certifying concurrent and distributed programs; - higher-order logics, logical systems, separation logics, and logics for security; - teaching mathematics and computer science with proof assistants. Submission Guidelines Papers should be submitted in PDF format through the EasyChair submission page at https://easychair.org/conferences/?conf=cpp2019 Submitted papers must be formatted following the ACM SIGPLAN Proceedings format using the acmart format with the sigplan option, using 10 point font for the main text, and a header for single blind review submission, e.g., \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. Shorter papers are welcome and will be given equal consideration. Submissions must be written in English and provide sufficient detail to allow the program committee to assess the merits of the paper. They should begin with a succinct statement of the issues, a summary of the main results, and a brief explanation of their significance and relevance to the conference, all phrased for the non-specialist. Technical and formal developments directed to the specialist should follow. References and comparisons with related work should be included. Submitted papers are not allowed to have an appendix. Papers not conforming to the above requirements concerning format and length may be rejected without further consideration. Whenever appropriate, the submission should come along with a formal development, using whatever prover, e.g., Agda, Coq, Dafny, Elf, HOL, HOL-Light, Isabelle, Lean, Matita, Mizar, NQTHM, PVS, Vampire, etc. Such formal developments must be submitted together with the paper as auxiliary material, and will be taken into account during the reviewing process. Please do so by including a link to your files in the text of your paper, or by sending a zip or tar file to the PC chairs at cpp2019@easychair.org with your paper number included in the subject of your email. The results must be unpublished and not submitted for publication elsewhere, including the proceedings of other published conferences or workshops. The PC chairs should be informed of closely related work submitted to a conference or journal in advance of submission. Original formal proofs of known results in mathematics or computer science are welcome. One author of each accepted paper is expected to present it at the conference. For any questions about the formatting or submission of papers, please consult the PC chairs (cpp2019@easychair.org). Conference webpage: https://popl19.sigplan.org/track/CPP-2019
