About GTTV'13

 

GTTV'13 is a workshop of LPNMR 2013 to be held on September 15th, 2013 in the city of Corunna, Spain. It is the second workshop of its series after GTTV'11 although it also inherits some topics from workshops CENT'07 and LaSh'10.

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
