11th Workshop on Horn Clauses for Verification and Synthesis (HCVS)

Co-located with ETAPS 2024

Call For Papers

7 April 2024 - Luxembourg

https://www.sci.unich.it/hcvs24/
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Important dates:

- Paper submission deadline: 2 February 2024
- Paper notification: beginning of March 2024
- Workshop: 7 April 2024

Scope:
Many Program Verification and Synthesis problems of interest can be 
modeled directly using Horn clauses and many recent advances in the CLP 
and CAV communities have centered around efficiently solving problems 
presented as Horn clauses.


This series of workshops aims to bring together researchers working in
the two communities of Constraint/Logic Programming (e.g., ICLP and CP), 
Program Verification (e.g., CAV, TACAS, and VMCAI), and Automated 
Deduction (e.g., CADE, IJCAR), on the topic of Horn clause based 
analysis, verification, and synthesis.


Horn clauses for verification and synthesis have been advocated by these
communities in different times and from different perspectives and HCVS 
is organized to stimulate interaction and a fruitful exchange and 
integration of experiences.

The workshop follows previous meetings: HCVS 2023 in Paris (ETAPS 2023), 
France (ETAPS 2023), HCVS 2022 in Munich, Germany (ETAPS 2022), HCVS 
2021, online (ETAPS 2021), HCVS 2020, online (ETAPS 2020), HCVS 2019 in 
Prague, Czech Republic (ETAPS 2019), HCVS 2018 in Oxford, UK (CAV, ICLP 
and IJCAR at FLoC 2018), HCVS 2017 in Gothenburg, Sweden (CADE 2017), 
HCVS 2016 in Eindhoven, The Netherlands (ETAPS 2016), HCVS 2015 in San 
Francisco, CA, USA (CAV 2015), and HCVS 2014 in Vienna, Austria (VSL).


Topics of interest include, but are not limited to the use of Horn 
clauses, constraints, and related formalisms in the following areas:

- Analysis and verification of programs and systems of various kinds 
(e.g., imperative, object-oriented, functional, logic, higher-order, 
concurrent, transition systems, petri-nets, smart contracts)
- Program synthesis
- Program testing
- Program transformation
- Constraint solving
- Type systems
- Machine learning and automated reasoning
- CHC encoding of analysis and verification problems
- Resource analysis
- Case studies and tools
- Challenging problems

We solicit regular papers describing theory and implementation of
Horn-clause based analysis and tool descriptions. We also solicit 
extended abstracts describing work-in-progress, as well as presentations 
covering previously published results, extended abstracts of doctoral 
theses, and overviews of research projects that are of interest to the 
workshop.

At least one author of each accepted paper will be required to attend
the workshop to present the contribution.


CHC Competition:
HCVS 2024 is planning to host the 7th competition on constraint Horn 
clauses (CHC-COMP https://chc-comp.github.io/), which will compare
state-of-the-art tools for CHC solving for performance and effectiveness 
on a set of publicly available benchmarks.


Program Chairs:
Julie Cailler,  University of Regensburg, Germany
Daniel Neider, Technical University of Dortmund, Germany


Submissions:
Submission has to be done in one of the following formats:

- Extended abstracts (up to 3 pages in EPTCS format), which describe 
work in progress or aim to initiate discussions.

- Presentation-only papers, i.e., papers already submitted or presented 
at a conference or another workshop. Such papers can be submitted in any
format, and will not be included in the workshop post-proceedings.

- Regular papers (up to 12 pages plus bibliography in EPTCS 
(http://www.eptcs.org/) format), which should present previously 
unpublished work (completed or in progress), including descriptions of 
research, tools, and applications.

- Tool papers (up to 4 pages in EPTCS format), including the papers 
written by the CHC-COMP participants, which can outline the theoretical 
framework, the architecture, the usage, and experiments of the tool.


All submitted papers will be refereed by the program committee and will 
be selected for inclusion in accordance with the referee reports.

If enough regular papers are accepted, both regular papers and extended 
abstracts will be published electronically. The publication of a paper 
is not intended to preclude later publication. Full versions of extended 
abstracts, or substantial revisions, may later be published elsewhere.

Papers must be submitted through the EasyChair system using the web page:
