HCVS 2020: Call For Papers

7th Workshop on Horn Clauses for Verification and Synthesis (HCVS)
Co-located with ETAPS 2020

Sunday 26 April 2020 - Dublin, Ireland 

https://www.sci.unich.it/hcvs20/ <https://www.sci.unich.it/hcvs20/>

Many Program Verification and Synthesis problems of interest can be
modeled directly using Horn clauses, and many recent advances in the
Constraint/Logic Programming, Verification, and Automated Deduction
communities have centered around efficiently solving problems
presented as Horn clauses.

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

Horn clauses have been advocated by these communities at different
times and from different perspectives, and this workshop is organized
to stimulate interaction and a fruitful exchange and integration
of experiences.

The workshop follows six previous meetings: 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), 
HCVS 2016 in Eindhoven, The Netherlands (ETAPS), HCVS 2015 in 
San Francisco, CA, USA (CAV), and HCVS 2014 in Vienna, Austria (VSL). 


Aims and Scope
--------------
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)
- Program synthesis
- Program testing
- Program transformation
- Constraint solving
- Type systems
- 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 that are of
interest to the workshop.


Important dates
---------------
- Paper submission: 26th February 2020
- Paper notification: 25th March 2020
- Camera-ready: 1st April 2020
- Workshop: 26th April 2020


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

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should present previously unpublished work (completed or in progress),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

- Tool papers (up to 4 pages plus bibliography 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.

- 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.

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

Authors of accepted papers are required to ensure that at least one of them
will be present at the workshop. Papers must be submitted through the
EasyChair system using the web page:
