Abstract
In this note a new model of grammatical picture generation is introduced. The model is based on the notion of pure context-free grammars of formal string language theory. The resulting model, called Pure 2D context-free grammar (CFG), generates rectangular picture arrays of symbols. The generative power of this model in comparison to certain other related models is examined. Also we associate a regular control language with a Pure 2D CFG and notice that the generative power increases. Certain closure properties are obtained.
