Plug-in context providers for reaction systems

Reaction systems originated as models of interactions between biochemical reactions in the living cell. Since then they were also successfully developed as models of interactive computation. Here, the interaction between a (reaction) system and its environment is modelled through context sequences provided by the environment - they influence the processes in the system. In this paper we introduce and investigate a 'plug-in' methodology for providing context sequences, where we view interactive processes from the perspective of the environment. The environment is modelled by a plug-in device, where a reaction system can be plugged in. When a reaction system is plugged in, then it receives context sequences from the plug-in device. Several sorts of such devices are investigated and compared (as influencers of behaviours of reaction systems). (C) 2020 Elsevier B.V. All rights reserved.
