How to extract negative information from programs is an important issue in logic programming. Here we address the problem for functional logic programs, from a proof-theoretic pers...
In modern functional logic languages like Curry or Toy, programs are possibly non-confluent and nonterminating rewrite systems, defining possibly non-deterministic non-strict fu...
Rewriting logic is a simple computational logic very well suited as a semantic framework within which many different models of computation, systems and languages can be naturally ...
Abstract. Deduction systems and graph rewriting systems are compared within a common categorical framework. This leads to an improved deduction method in diagrammatic logics.
