Thus, beyond reachability, a player may restrict attention to paths that satisfy certain properties, referring, for example, to the providers of the traversed edges, the actions associated with them, their quality of service, or security. Our results show that the transition

Krzysztof R. Apt,Ernst-Rüdiger Olderog shield the design from the details of the underlying cryptographic infrastructure. We discuss an implementation of the abstractions based on a translation from the . notation to the AnB language supported by the OFMC [1,2] verification tool. We show the practical effectiveness of our approach by re

examine the extended use of context lemmas during proof search by allowing the use of context lemmas for subsumption of new tableau clauses. We also show limitations to this method. Both techniques described in this paper are being implemented as part of the DCTP disconnection tableau prover.

We show that . and . are equivalent, that is, any cut-free proof of . can be transformed into a cut-free proof of ., and vice versa. We consider two ext

s result, combined with a ‘one-step version’ of the classical correspondence theory, turns out to be quite powerful in applications. For simple logics such as ., ., ., ., etc, establishing basic metatheoretical properties becomes a completely automatic task (the related proof obligations can be inst
