Efficient Modular Graph Transformation Rule Application [article]

Jakob L. Andersen, Rolf Fagerberg, Juri Kolčák, Christophe V.F.P. Laurent, Daniel Merkle, Nikolai Nøjgaard
2022 arXiv   pre-print
In this contribution, we develop a new method of enumerating graph matches during graph transformation rule application.  ...  We further extend the algorithm with an efficient heuristic based on local symmetries of the graphs, which allow us to detect and discard isomorphic applications early.  ...  Conclusion We design a new efficient algorithm for enumerating the matches of graph transformation rules in the application area of chemical reaction networks.  ...

The Graph Grammar Library - a generic framework for chemical graph rewrite systems [article]

Martin Mann, Heinz Ekker, Christoph Flamm
2013 arXiv   pre-print
Here, molecules are represented as undirected labeled graphs while chemical reactions are described by according graph grammar rules.  ...  Beside the graph transformation, the GGL offers advanced cheminformatics algorithms for instance to estimate energies ofmolecules or aromaticity perception.  ...  with a flexible and efficient rule application framework.  ...

Modularized Constraint Management in Model Transformation Frameworks

2013 Acta Polytechnica Hungarica  
The precise definition of graph rewriting-based model transformation requires that beyond the topology of the rules, further textual constraints be added.  ...  These constraints often appear repetitively in a transformation; therefore, constraint concerns crosscut the transformation.  ...  A set of rewriting rules define a graph transformation system. The applications of these rules are the elementary operations of graphs.  ...

Constraint projection

Mikio Nakano
1991 Proceedings of the 29th annual meeting on Association for Computational Linguistics -  
Unification of disjunctive feature descriptions is important for efficient unification-based parsing.  ...  Constraint projection is a generalization of constraint unification, and is more efficient because constraint projection has a mechanism for abandoning information irrelevant to a goal specified by a list  ...  Since abandoning irrelevant information makes the resulting structure tighter, another application of phrase structure rules to it will be efficient.  ...

Issues in the practical use of graph rewriting [chapter]

Dorothea Blostein, Hoda Fahmy, Ann Grbavec
1996 Lecture Notes in Computer Science  
Efficiency considerations and the limited availability of development tools further limit practical use of graph rewriting.  ...  Graphs are a popular data structure, and graph-manipulation programs are common. Graph manipulations can be cleanly, compactly, and explicitly described using graph-rewriting notation.  ...  Host-graph triggers This method of modularization is proposed for an unordered graph-rewriting system (wherein a host-graph is nondeterministically transformed by a set of graph-rewrite rules, with no  ...

Modularizing Triple Graph Grammars Using Rule Refinement [chapter]

Anthony Anjorin, Karsten Saller, Malte Lochau, Andy Schürr
2014 Lecture Notes in Computer Science  
Triple Graph Grammars (TGGs) are a formally founded, bidirectional transformation language, which has been used successfully in various case studies from different applications domains.  ...  In this paper, we present and formalize a novel modularity concept for TGGs: Rule refinement, which generalizes existing modularity concepts, solves the problem of pattern duplication, and enables concise  ...  Modularity Concepts for Graph Transformations: There are numerous modularity concepts in the mature field of graph transformation.  ...

Automated Termination Proofs with AProVE [chapter]

Jürgen Giesl, René Thiemann, Peter Schneider-Kamp, Stephan Falke
2004 Lecture Notes in Computer Science  
In particular, it contains many new improvements of the dependency pair approach that make automated termination proving more powerful and efficient.  ...  For this system, we have developed and implemented efficient algorithms based on classical simplification orders, dependency pairs, and the size-change principle.  ...  DP Graph For TRSs with many rules, (innermost) termination proofs should be performed in a modular way.  ...

Model transformation in the large

Felix Klar, Alexander Königs, Andy Schürr
2007 Proceedings of the the 6th joint meeting of the European software engineering conference and the ACM SIGSOFT symposium on The foundations of software engineering - ESEC-FSE '07  
Current rule-based model transformation approaches as the Query / View / Transformation (QVT) standard or Triple Graph Grammars (TGGs) disregard means for structuring model transformation specifications  ...  As a result large scale model transformation specifications are hard to understand and to maintain.  ...  In order to develop and maintain such systems efficiently developers need appropriate modeling languages that allow for the modularization of the systems into smaller and more manageable subsystems as  ...

Detection of Syntactic Aspect Interaction in UML State Diagrams Using Critical Pair Analysis in Graph Transformation [article]

Zaid Altahat, Tzilla Elrad, Luay Tahat, Nada Almasri
2013 arXiv   pre-print
This identified problem is similar to a phenomenon that exists in graph transformation systems where multiple Graph Transformation rules share some conflicting elements, it is referred to as Critical Pair  ...  The proposed framework transforms Aspects modeled in UML State Diagram to Graph Transformation Rules, and then it applies Critical Pair Analysis to detect unintended interactions among aspects.  ...  P may also have a set of Negative Application Conditions (NAC), which are elements that may not exist for a rule to apply. A GT rule replaces graph L with R in host graph G.  ...
