Designing Graph Drawings by Layout Graph Grammars [PDF]

open access: yes, 1995
Layout graph grammars are a grammatical or rule-based method for the construction of graphs and of their drawings. As such they are representatives of the so-called declarative approach. A layout graph grammar consists of an underlying context-free graph

Nested Term Graphs (Work In Progress) [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
We report on work in progress on 'nested term graphs' for formalizing higher-order terms (e.g. finite or infinite lambda-terms), including those expressing recursion (e.g. terms in the lambda-calculus with letrec).

A Solution to the Flowgraphs Case Study using Triple Graph Grammars and eMoflon [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
After 20 years of Triple Graph Grammars (TGGs) and numerous actively maintained implementations, there is now a need for challenging examples and success stories to show that TGGs can be used for real-world bidirectional model transformations.

A Multi-Agent System in Education Facility Design

open access: yesApplied Sciences, 2023
This paper deals with a multi-agent system which supports the designer in solving complex design tasks. The behaviour of design agents is modelled by sets of grammar rules.

TOWARDS A GENERIC MAPPING FOR IFC-CITYGML DATA INTEGRATION [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Much work has been carried out on the topic of BIM-GIS integration. As a technical challenge in particular, research and development tackle the standard data formats of the two areas and aim for the conversion between, linking of or overarching querying ...

Event Structure Semantics for Dynamic Graph Grammars [PDF]

open access: yes, 2007
Dynamic graph grammars (DGGs) are a reflexive extension of Graph Grammars that have been introduced to represent mobile reflexive systems and calculi at a convenient level of abstraction.

Context-Sensitive Languages, Rational Graphs and Determinism [PDF]

open access: yesLogical Methods in Computer Science, 2006
We investigate families of infinite automata for context-sensitive languages. An infinite automaton is an infinite labeled graph with two sets of initial and final vertices.

The Category of Typed Graph Grammars and its Adjunctions with Categories of Derivations [PDF]

open access: yes, 1996
Motivated by the work which has been done for Petri-nets, the paper presents a categorical approach to graph grammars “in the large”. In the large means, that we define categories of graph grammars, graph transition systems, and graph derivation systems ...

Towards the specification and verification of modal properties for structured systems [PDF]

open access: yes, 2012
System specification formalisms should come with suitable property specification languages and effective verification tools. We sketch a framework for the verification of quantified temporal properties of systems with dynamically evolving structure.
