Abstract. This article presents a database of about 200 graph invariants for deriving systematically necessary conditions from the graph properties based representation of global c...

Abstract. Graph constraints were introduced in the area of graph transformation, in connection with the notion of (negative) application conditions, as a form to limit the applicab...
The aim of this paper is an integration of graph grammars with different kinds of behavioural constraints, in particular with temporal logic constraints. Since the usual algebraic ...

We study extensions of first-order logic over the reals with different types of transitive-closure operators as query languages for constraint databases that can be described by...
We suggest a formal model to represent and solve the multicast routing problem in multicast networks. To attain this, we model the network adapting it to a weighted and-or graph, ...
