2nd Edition, as published by Charles François 2004 Presented by the Bertalanffy Center for the Study of Systems Science Vienna for public access.

About

The International Encyclopedia of Systems and Cybernetics was first edited and published by the system scientist Charles François in 1997. The online version that is provided here was based on the 2nd edition in 2004. It was uploaded and gifted to the center by ASC president Michael Lissack in 2019; the BCSSS purchased the rights for the re-publication of this volume in 200?. In 2018, the original editor expressed his wish to pass on the stewardship over the maintenance and further development of the encyclopedia to the Bertalanffy Center. In the future, the BCSSS seeks to further develop the encyclopedia by open collaboration within the systems sciences. Until the center has found and been able to implement an adequate technical solution for this, the static website is made accessible for the benefit of public scholarship and education.

GRAPH GRAMMAR (Sequential) 2)5)

← Back

D. GERNERT explains how graphs can be rewrited, thus generating a sequential graph grammar through embedding rules. He describes as follows some important properties of this type of representation graphs:

1. The new graph generated by a production rule can be "more complex"or "less complex" than the old one

2. The continuation of the rewriting process is not necessarily unique: there may be nondeterminism as well as determinism, or a combination of both, depending on the features of the individual graph grammar

3. There may be different sequences of derivation steps which lead to the same result, the "genesis" of a graph is not necessarily unique

4. A sequence of derivation steps can lead to the start graph again: "periodic graph grammars" are possible

5. In degenerate cases it may happen that none of the production rules are applicable so that the procedure stops
