A sequent calculus of a new sort is extracted from the Prolog program leanTAP. This calculus is sound and complete, even though it lacks almost all structural rules. Thinking of l...
—A system of linear dependent types for the lambda calculus with full higher-order recursion, called d PCF, is introduced and proved sound and relatively complete. Completeness h...
We present an approach for checking code against rich specifications, based on existing work that consists of encoding the program in a relational logic and using a constraint sol...
We introduce pseudo-naive evaluation, a method for execution of mixed top-down/bottom-up logic programs and deductive databases. The method is intermediate in power between naive ...
We propose a practical path-based framework for deriving and simplifying source-tracking information for term unification in the empty theory. Such a framework is useful for debugg...
