Abstract

Abstract We present algorithms for analyzing single graphs and sets of graphs generated by boundary node label controlled (BNLC) graph grammars. This paper extends a unified framework for developing algorithms on context-free graph languages to BNLC graph languages. Graphs in BNLC graph languages do not necessarily have vertex separators of bounded size as do graphs in context-free graph languages. We give combinatorial decision and query algorithms on single graphs generated by a deterministic BNLC graph grammar and algorithms for the following question: Does the language of a given BNLC graph grammar contain a graph that fulfills a certain graph property? All algorithms developed in this paper consider the graph grammar as input.
