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 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).
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.
CHC Competition
HCVS 2020 will host the 3rd competition on constraint Horn clauses (CHC-COMP),
which will compare state-of-the-art tools for CHC solving for performance and effectiveness on a set of publicly available benchmarks.
A report on the 3rd CHC-COMP will be part of the workshop's proceedings.
The report contains also tool descriptions of the participating solvers.
Dates
Paper submission:
Wednesday 26th February 2020 AoE 8th March 2020 AoE DEADLINE EXTENDED
Submission has to be done in one of the following formats:
Regular papers (up to 12 pages plus bibliography, typeset in
EPTCS format),
which should present previously unpublished work
(completed or in progress), including descriptions of research,
tools, and applications.
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 refereed by the program committee and
will be selected for inclusion in accordance with the referee
reports. Accepted regular papers and extended abstracts will be
published electronically as a volume in the Electronic Proceedings in
Theoretical Computer Science (EPTCS) series, see http://www.eptcs.org/
(provided that enough regular papers are accepted).
Authors of accepted papers are required to ensure that at
least one of them will be present at the workshop.
