Call for Participant Systems

Participants of the Answer Set Programming Competition will compete on a selected collection of benchmark problems, taken from a variety of benchmark problem domains as well as real world applications. These include, but are not limited to:

• Classic and applicative graph problems
• Scheduling, Timetabling, and other resource allocation problems
• Sequential and Temporal Planning
• Combinatorial Optimization Problems
• Deductive database tasks on large data-sets
• Puzzles and Combinatorics
• Ontology reasoning
• Automated Theorem Proving and Model Checking
• Reasoning tasks over large propositional instances
• Constraint Programming problems
• Other AI problems

The competition consists of two independent main tracks:

• the Model & Solve Track invites any researcher and developer of

  • declarative knowledge representation systems to participate in an open challenge for solving sophisticated AI problems with their tools of choice. Participants submit a solver based on an arbitrary input format and declarative specifications of the Competition's benchmark domains;
• the System Track compares dedicated answer set solvers on ASP
  • benchmarks. Participants compete with a solver for a standard ASP language.

We encourage to submit parallel and portfolio systems exploiting multiple cores or multiple algorithms for solving the given instances.

About the Answer Set Programming Competition Series

Answer Set Programming is a well-established paradigm of declarative programming with close relationship to other declarative modelling paradigms and languages, such as SAT Modulo Theories, Constraint Handling Rules, FO(.), PDDL, CASC, and many others.

The ASP Competition is a biannual event for evaluating declarative knowledge representation systems on hard and demanding AI problems. The 4th ASP Competition will be run in the first half of 2013 jointly at the University of Calabria (Italy) and the Vienna University of Technology (Austria). The event is the sequel to the ASP Competition series, held at the University of Potsdam (Germany) in 2006-2007, at the University of Leuven (Belgium) in 2009, and at University of Calabria (Italy) in 2011. The current competition takes place in cooperation with the 12th International Conference on Logic Programming and Nonmonotonic Reasoning (LPNMR 2013), where the results will be announced.

The ASP competition is held as an open tournament. The "Model & Solve" competition track fosters the spirit of integration among communities, and is thus open to all types of solvers: ASP systems, SAT solvers, SMT solvers, CP systems, FOL theorem provers, Description Logics reasoners, planning reasoners, or any other. The "System" competition track is instead set up on a fixed language based on the answer set semantics.
