Hans Schumann,Manfred Winter,Wolfgang Petz(2) we generalize algebraic operations to diagrammatic operations over graphs, which we call ..Our main objective is to extend the construction of term algebras, i.e., free algebras, for the new setting. The key mechanism for the construction of free graph algebras are pushout-based graph transforma

On the Essence of Parallel Independence for the Double-Pushout and Sesqui-Pushout Approaches, static analysis techniques like Critical Pair Analysis. We propose a new categorical condition of parallel independence and show its equivalence with two other conditions proposed in the literature, for both left-linear and non-left-linear rules. Next we present some preliminary experimental result

Integration of Graph Constraints into Graph Grammars, does there exist a “goal-oriented” grammar that generates all graphs of the original graph language satisfying the constraint. We solve the filter problem for specific graph grammars and specific graph constraints. As an intermediate step, we construct a constraint automaton accepting exactly the g

A Tutorial on Graph Transformation,te rules are used to manipulate graphs. These rules are given by a left-hand side and a right-hand side graph and the application comprises matching the left-hand side and replacing it with the right-hand side of the rule..In this contribution we give a tutorial on graph transformation that explains

Towards a Navigational Logic for Graphical Structures,c can be used in the framework of many classes of graphs and graphical structures. It is enough that the category of these structures satisfies certain basic conditions..In a previous paper [.], we extended this logic to be able to deal with graph properties including paths, but this extension was o

Decomposition Structures for Soft Constraint Evaluation Problems: An Algebraic Approach,tion problems. A variety of algorithms to tackle them have been studied in the last 45 years, many of them based on dynamic programming. A limit of SCSPs is its lack of compositionality and, consequently, it is not possible to represent problem decompositions in the formalism itself. In this paper w
