Abstract: The narrowing relation over terms constitutes the basis of the most important operational semantics of languages that integrate functional and logic programming paradigms...
We extend the well-known Tree-Diffie-Hellman technique used for the design of group key exchange (GKE) protocols with robustness, i.e. with resistance to faults resulting from poss...
Abstract. Constraint Handling Rules (CHR) is a concurrent, committed-choice, rule-based language. One of the first CHR programs is the classic constraint solver for syntactic equal...
Narrowing extends rewriting with logic capabilities by allowing free variables in terms and replacing matching with unification. Narrowing has been widely used in different context...
