Propositional theories are strongly equivalent to logic programs
In this paper we show that an arbitrary propositional theory, when interpreted under the answer sets semantics (called Equilibrium Logic for this general syntax), can always be re...

Loop Formulas for Logic Programs with Arbitrary Constraint Atoms
We formulate loop formulas for logic programs with arbitrary constraint atoms, for the semantics based on conditional satisfaction. This provides a method for answer set computati...
