An Incompleteness Result for Deductive Synthesis of Logic Programs Kung-Kiu Lau Department of Computer Science, University of Manchester Oxford Road, Manchester M13 9PL, United Kingdom kung-kiu@cs.man.ac.uk Mario Ornaghi Dipartimento di Scienze dell'Informazione Universita' degli studi di Milano Via Comelico 39/41, Milano, Italy ornaghi@dsi.unimi.it Abstract: We formalise the derivation of logic programs from their specifications by deductive synthesis, and introduce the notion of uniform equivalence between logical systems. This enables us to present an incompleteness result for deductive synthesis of logic programs from first-order logic specifications.
