Abstract
We prove that -.unless the polynomial hierarchy collapses at the second level - the size of a purely propositional representation of the circumscription CIRC(T) of a propositional formula T grows faster than any polynomial as the size of T increases. We then analyze the significance of this result in the related field of closed-world reasoning.File allegati a questo prodotto
