Reaction systems with influence on environment
Reaction systems, motivated by the functioning of the living cell, became a novel model of interactive computation. In this paper, we pursue this line of research. More specifically, we present a systematic investigation of possible interactions of a reaction system with its environment (context). While in the original definition this interaction is one-way, i.e., the behavior of a reaction system is influenced by its environment, we investigate now also the influence of the system on its environment, where a possible time delay of this influence is also considered. To understand the behavior of reaction systems when such a two-way interaction takes place, we establish its relationship to their context-independent behavior (i.e., the behavior which is not influenced by the environment).
