Controllability of reaction systems

Abstract

Controlling a dynamical system is the ability of changing its configuration arbitrarily through a suitable choice of inputs. It is a very well-studied concept in control theory, with wide-ranging applications in medicine, biology, social sciences and engineering. We introduce in this article the concept of controllability of reaction systems as the ability of transitioning between any two states through a suitable choice of context sequences. We show that the problem is PSPACE-hard. We also introduce a model of oncogenic signalling based on reaction systems and use it to illustrate the intricacies of the controllability of reaction systems. This study opens up a new line of research on the dynamic properties of reaction systems and it introduces a new, intricate biomedical model based on reaction systems.

P versus B: P Systems as a Formal Framework for Controllability of Boolean Networks

“…Reaction systems [8] are intrinsically interesting for discussing controllability, because they are defined as open systems from the start, via the explicit introduction of context. We refer to [14] for an in-depth discussion of controllability of reaction systems.…”
