ChemTrains: a language for creating behaving pictures
B. Bell, Cassidy Lewis · 2002
ChemTrains is a rule-based language in which both the condition and action of each rule are specified by pictures. A ChemTrain rule will execute when the topology rather than the geometry of a pattern matches a portion of the simulation picture, enabling rules to be drawn at a high level of abstraction. The language is independent of any specific application domain and is accessible to people with limited programming knowledge.>
