Transformations of graph grammars

1996
The notion of multilevel graph representations, where parts of graphs are not visible and the information can be restored via the explicit application of productions, and the corresponding extension of the classical double pushout approach is generalized to the algebraic theory of graph grammars and to the rewriting of these grammars, at the global ...

Programmed graph grammars

2005
Let [enum], [exp-i] and [pr-i] denote the class of recursively enumerable, typ-i expression and typ-i programmed graph languages respectively. The following hierarchy is known from [5]:

Integration of Graph Constraints into Graph Grammars

2018
We investigate the integration of graph constraints into graph grammars and consider the filter problem: Given a graph grammar and a graph constraint, does there exist a “goal-oriented” grammar that generates all graphs of the original graph language satisfying the constraint.

Graph grammars and logic programming

2005
In this paper we investigate the relationship between the algebraic definition of graph grammars and logic programming. In particular, we show that the operational semantics of any logic program can be faithfully simulated by a particular context-free hypergraph grammar.

On the relation of graph grammars and graph automata

13th Annual Symposium on Switching and Automata Theory (swat 1972), 1972
It is shown that a strong relationship exists between sets of graphs defined by graph (walking) automata with markers available and sets defined by graph grammars. Polynomial recognition algorithms are presented for certain classes of sets and it is argued that the existence of polynomial algorithms for other classes is doubtful.

Graph grammars based on node rewriting: an introduction to NLC graph grammars

2005
An elementary introduction to the notion of an NLC graph grammar is given, and several of its extensions and variations are discussed in a systematic way. Simple concepts are considered rather than technical details.

First Order Graph Grammars

SIAM Journal on Computing, 1974
In this paper we consider first order context-free, linear, and regular graph grammars and obtain many results similar to those for the corresponding string grammars. We obtain normal forms for context-free and regular graph grammars, simplification lemmas, and algorithms for membership, emptiness, finiteness and infiniteness.

Graph-grammars: An algebraic approach

14th Annual Symposium on Switching and Automata Theory (swat 1973), 1973
The paper presents an algebraic theory of graph-grammars using homomorphisms and pushout-constructions to specify embeddings and direct derivations constructively. We consider the case of arbitrary directed graphs permitting loops and parallel edges.
