Linear graph grammar

In computer science, a linear graph grammar (also a connection graph reduction system or a port graph grammar^[1]) is a class of graph grammar on which nodes have a number of ports connected together by edges and edges connect exactly two ports together. Interaction nets are a special subclass of linear graph grammars in which rewriting is confluent.

Implementations

Bawden introduces linear graphs in the context of a compiler for a fragment of the Scheme programming language.^[2] Bawden and Mairson (1998) describe a the design of a distributed implementation in which the linear graph is spread across many computing nodes and may freely migrate in order to make rewrites possible.

Notes

↑ Bawden (1986) introduces the formalism calling them connection graphs.
↑ Bawden (1993) is the technical report based on the Ph.D. dissertation, Bawden (1992).
