== Competition Tracks ==

The ASP Competition Series consisted usually of (sub)-Tracks conceived on the basis of the "complexity" of problems; in the light of the work spent by the community on language standardization, this edition takes rather into consideration language features.

As stated by the Call for Participation, according to the availability of benchmarks, to submitted systems, and to participants feedback, the competition is hence structured into four tracks:

 || Track # || Track Name || Track features ||
 || 1 || Basic || Basic Decision. Encodings: normal LP + simple arithmetic and comparison operators ||
 || 2 || Advanced || Advanced Decision. Encodings: full language, excepting optimization statements and non-HCF disjunction ||
 || 3 || Optimization || Optimization. Encodings: full language with optimization statements, excepting non-HCF disjunction ||
 || 4 || Unrestricted || Unrestricted. Encodings: full language ||
