Certified Programs and Proofs (CPP) is an international conference on
practical and theoretical topics in all areas that consider formal
verification and certification as an essential paradigm for their
work. CPP spans areas of computer science, mathematics, logic, and
education.

CPP 2022 (https://popl22.sigplan.org/home/CPP-2022) will be held on
17-18 January 2022 and will be co-located with POPL 2022 in
Philadelphia, Pennsylvania, United States. CPP 2022 is sponsored by
ACM SIGPLAN, in cooperation with ACM SIGLOG.

CPP 2022 will welcome contributions from all members of the community.
The CPP 2022 organizers will strive to enable both in-person and
remote participation, in cooperation with the POPL 2022 organizers.

NEWS

If the authors of a CPP 2022 accepted paper will be unable or
unwilling to travel to the conference, the organizers can confirm that
this will not affect the paper’s publication in the proceedings, and
the authors will be able to upload recorded talks that will be made
publicly available.

IMPORTANT DATES

* Abstract Submission Deadline: 16 September 2021 at 23:59 AoE (UTC-12h)

DISTINGUISHED PAPER AWARDS

Around 10% of the accepted papers at CPP 2022 will be designated as
Distinguished Papers. This award highlights papers that the CPP
program committee thinks should be read by a broad audience due to
their relevance, originality, significance and clarity.

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 interest to CPP:
* certified or certifying programming, compilation, linking, OS
kernels, runtime systems, security monitors, and hardware;
* certified mathematical libraries and mathematical theorems;
* proof assistants (e.g, ACL2, Agda, Coq, Dafny, F*, HOL4, 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;
* formally certified methods for induction and coinduction;
* integration of interactive and automated provers;
* logical foundations of proof assistants;
* applications of AI and machine learning to formal certification;
* user interfaces for proof assistants and theorem provers;
* teaching mathematics and computer science with proof assistants.

SUBMISSION GUIDELINES

Prior to the paper submission deadline, the authors should upload
their anonymized paper in PDF format through the HotCRP system at

https://cpp2022.hotcrp.com

The submissions must be written in English and provide sufficient
detail to allow the program committee to assess the merits of the
contribution. They must be formatted following the ACM SIGPLAN
Proceedings 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,anonymous,review]{acmart}\settopmatter{printfolios=true,printccs=false,printacmref=false}

The submitted papers should not exceed 12 pages, including tables and
figures, but excluding bibliography and clearly marked appendices. The
papers should be self-contained without the appendices. Shorter papers
are welcome and will be given equal consideration. Submissions not
conforming to the requirements concerning format and maximum length
may be rejected without further consideration.

CPP 2022 will employ a lightweight double-blind reviewing process. To
facilitate this, the submissions 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 it 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 papers as usual. For example, authors may
post drafts of their papers on the web or give talks on their research
ideas. POPL has answers to frequently asked questions addressing many
common concerns:
https://popl20.sigplan.org/track/POPL-2020-Research-Papers#Submission-and-Reviewing-FAQ

We strongly encourage the authors to provide any supplementary
material that supports the claims made in the paper, such as proof
scripts or experimental data. This material must be uploaded at
submission time, as an archive, not via a URL. Two forms of
supplementary material may be submitted:
(1) Anonymous supplementary material is made available to the
reviewers before they submit their first-draft reviews.
(2) Non-anonymous supplementary material is made available to the
reviewers after they have submitted their first-draft reviews and have
learned the identity of the authors.

Please use anonymous supplementary material whenever possible, so that
it can be taken into account from the beginning of the reviewing
process.

The submitted papers must adhere to the SIGPLAN Republication Policy
(https://www.sigplan.org/Resources/Policies/Republication/) and the
ACM Policy on Plagiarism
(https://www.acm.org/publications/policies/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 (possibly virtual)
conference.

PUBLICATION, COPYRIGHT AND OPEN ACCESS

The CPP 2022 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 preprint 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 2022 proceedings will also be available via SIGPLAN
OpenTOC (http://www.sigplan.org/OpenTOC/#cpp).

For ACM’s take on this, see their Copyright Policy
(http://www.acm.org/publications/policies/copyright-policy) and Author
Rights (http://authors.acm.org/main.html).
