1st Workshop on Grounding and Transformations for Theories with Variables
GTTV 2011

http://www.dc.fi.udc.es/GTTV11/

Collocated with the 11th Intl. Conf. on
Logic Programming and Nonmonotonic Reasoning 2011

Vancouver, BC, Canada
May 16-19, 2011
---------------------------------------------------------------------------

AIMS AND SCOPE

Although many efficient solvers used in formal reasoning operate at the
propositional level, in most application domains for knowledge
representation and reasoning the use of variables is crucial for allowing
compact and flexible formal descriptions. As a result, a common situation
in many different areas of formal reasoning is to deal with high level
descriptions containing variables while using a propositional solver as a
backend. The technique of removing variables, replacing them by their
possible ground instances, is commonly known as Grounding, and has
attracted research interest from quite diverse areas such as Logic
Programming and Non-Monotonic Reasoning, Theorem Proving, Planning,
Deductive Databases, Formal Methods, and others.

This workshop aims to bring together researchers from different areas with
a common interest in grounding and transformations for theories with
variables, establishing a meeting point from which a cross-fertilization
of new ideas may emerge.

Workshop topics include, but are not limited to:

* Transformations and pre-processing for grounding
* Equivalence and correspondence for theories with variables
* Modularity and compositionality
* Syntactic restrictions for grounding
* Grounding for theories with functions
* Selective on-the-fly grounding
* Grounding algorithms: heuristics, computational complexity, etc
* Benchmarks, challenging applications and system comparisons
* Grounding for specific solvers including, but not limited to:
ASP, SAT, SMT, etc
* Grounding in hybrid systems: ontologies, constraint handling, etc

SUBMISSIONS

All submissions must be written in English and formatted according to the
Springer LNCS/LNAI author instructions.

http://www.springer.com/comp/lncs/Authors.html

Two types of contributions are accepted: Technical papers and System
descriptions. Technical papers must present original research and not
exceed 13 pages including title page, references and figures. Since it is
the first meeting and we expect to collect contributions from different
areas, we also encourage introductory system descriptions that help each
group make their work known to the others. For system presentations a
length of 6 pages is recommended.

Paper submission is electronic and managed through the following easychair
GTTV11 webpage

MULTIPLE SUBMISSION POLICY

GTTV'11 will not accept any paper which, at the time of submission, has
already been published or accepted for publication in a journal or previous
conference. However, authors may freely sumbit their papers elsewhere
during or after GTTV'11 review period, since GTTV'11 is a specialised
workshop without archival proceedings and intended for a limited audience.
