Subject: [isabelle] 1st CFP - CPP 2027 - Certified Programs and Proofs
Call for Papers
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 2027 (https://popl27.sigplan.org/home/CPP-2027) will be held on
11-12 January 2027 and will be co-located with POPL 2027 in Mexico City,
Mexico. CPP 2027 is sponsored by ACM SIGPLAN, in cooperation with ACM
SIGLOG.
CPP 2027 will welcome contributions from all members of the community.
CPP 2027 is primarily an in-person event, and at least one author of
every accepted paper is expected to attend in person. We aim to support
remote participation, with talks recorded and streamed online depending
on AV support from the POPL 2027 organizers.
IMPORTANT DATES
Abstract submissions: Sep 3, 2026
Paper submissions: Sep 10, 2026
First round of reviews due: Oct 10, 2026
Second round of reviews due: Nov 3, 2026
Author notifications: Nov 10, 2026
Camera-ready deadline: Nov 25, 2026
Deadlines expire at the end of the day, anywhere on earth. Abstract and
submission deadlines are strict and there will be no extensions.
AUTHORS TAKE NOTE
The official publication date is the date the proceedings are made
available in the ACM Digital Library. This date may be up to two weeks
prior to the first day of your conference. The official publication date
affects the deadline for any patent filings related to published work.
DISTINGUISHED PAPER AWARDS Around 10% of the accepted papers at CPP 2027
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, Dafny, F*, HOL4, HOL Light,
Idris, Isabelle, Lean, Mizar, Nuprl, PVS, Rocq, 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;
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 verification;
user interfaces for proof assistants and theorem provers;
teaching mathematics and computer science with proof assistants.
Submissions will be reviewed based on the following criteria:
Thoroughly discuss the theory or design choices underpinning the
formalization.
Provide a detailed explanation of the formalization decisions,
including alternative approaches and reasons for rejecting them.
Examine related literature on formalization choices and techniques.
Compare the design choices to those made in other libraries.
Offer feedback on the features of the computer proof assistant
used, noting any that are missing.
Draw conclusions that can guide future formalization efforts in the
same or other 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
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 2027 will employ a lightweight double-blind reviewing process
following the process from previous years. To facilitate this, the
submissions must adhere to two rules:
author names and institutions must be omitted, and
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. Note that POPL 2027
itself will employ full double-blind reviewing, which differs from the
light-weight CPP process. This FAQ from previous SIGPLAN conference
addresses many common concerns:
https://popl20.sigplan.org/track/POPL-2020-Research-Papers#Submission-and-Reviewing-FAQ
SUPPLEMENTARY MATERIAL
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:
Anonymous supplementary material is made available to the reviewers
before they submit their first-draft reviews.
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. In order to facilitate reviewing, we encourage authors to
hyperlink paper statements to their counterpart in the supplementary
material.
AUTHORSHIP POLICY
The submitted papers must adhere to the ACM Policy on Authorship
(https://www.acm.org/publications/policies/new-acm-policy-on-authorship,
which includes a section on the “Use of Artificial Intelligence”) and on
Plagiarism (https://www.acm.org/publications/policies/plagiarism) and to
the SIGPLAN Republication
Policy(https://www.sigplan.org/Resources/Policies/Republication/) and.
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.
AI POLICY
CPP will follow the ACM policy on the use of AI in preparing papers,
that we invite authors to read carefully
https://www.acm.org/publications/policies/frequently-asked-questions
Notably, authors can use AI tools in preparing their papers, with the
conditions: - That these systems do not plagiarize, misrepresent, or
falsify content in ACM submissions. - That the resulting work in its
totality is an accurate representation of the authors’ underlying work
and novel intellectual contributions and is not primarily the result of
the tool’s generative capabilities. - That the authors accept
responsibility for the veracity and correctness of all material in their
Work, including any computer-generated material.
Especially with the rapid growth in AI-assisted proofs and
autoformalization, we expect that you, like us, are concerned about the
volume and quality of papers submitted to CPP. We thus ask authors to
strictly respect the above mentioned policies, as the PC is entitled to
desk reject papers that fail them.
ANTICIPATING REVIEWING LOAD
CPP usually guarantees that all papers get three reviews. However, with
the rapid growth in conference submissions, in the event that we receive
submissions far exceeding last year’s record number, we may need to
weaken this guarantee. In particular, as has been the case at other
recent SIGPLAN conferences, we may resort to the early rejection of
papers with two negative reviews.
