Graph Invariants as Necessary Conditions for Global Constraints
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...

A Logic of Graph Constraints
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...

Integrating the Specification Techniques of Graph Transformation and Temporal Logic
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 ...

Deciding Termination of Query Evaluation in Transitive-Closure Logics for Constraint Databases
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...

Modelling Multicast QoS Routing by using Best-Tree Search in And-or Graphs and Soft Constraint Logic Programming
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, ...
