Guiding Synthesis Proofs

In this paper, we present a basic set of methods to guide a proof in the Whelk logic program synthesis system. Starting from the methods used in the Oyster/CLaM system, designed for a functional context, we developed some proof "critics" to solve the cases in which those methods are blocked in a relational context. The application of those methods and proof critics is illustrated by an example, the delete predicate synthesis
