A Formal Framework for Synthesis and Verification of Logic Programs

In this paper we present a formal framework, based on the notion of extraction calculus, which has been applied to define procedures for extracting information from constructive proofs. Here we apply such a mechanism to give a proof-theoretic account of SLD-derivations. We show how proofs of suitable constructive systems can be used in the context of deductive synthesis of logic programs, and we state a link between constructive and deductive program synthesis.
