Transforming co-NP Checks to Answer Set Computation by Meta-Interpretation
Many NP-complete problems can be encoded in the answer set semantics of logic programs in a very concise way, where the encoding reflects the typical “guess and check” nature ...

Towards Automated Integration of Guess and Check Programs in Answer Set Programming
Abstract. Many NP-complete problems can be encoded in the answer set semantics of logic programs in a very concise way, where the encoding reflects the typical “guess and check...

Fixed-Parameter Hierarchies inside PSPACE
Treewidth measures the ”tree-likeness” of structures. Many NP-complete problems, e.g., propositional satisfiability, are tractable on bounded-treewidth structures. In this wo...
