The 2020 Workshop on Reaction Systems will take place from Wednesday, June 3, until Friday, June 5. The workshop program will cover the recent as well as by now established scientific results. Also, the presentations of work in progress are welcome. Moreover, the program of the workshop includes sessions which instigate collaboration of workshop participants.

Information about the participation fees will be available soon.

Regular contributions to the Workshop

We encourage submissions concerned with reaction systems and related areas. The submissions will be collected in local proceedings. We plan to prepare (after the workshop) a special issue of a reputable international journal which will include selected contributions to the workshop.

If you plan to contribute to the workshop, then please submit (to ion.petre@utu.fi) an extended abstract not later than April 10. You will receive a notification of possible inclusion soon afterwards.

Keynote speakers (to be updated)

  • E. Csuhaj-Varju, Budapest, Hungary. P systems vs. R systems: Concepts and Results.

Abstract:

The theory of P systems (membrane computing) and that of R systems (reaction systems)  are two areas of natural computing, both inspired by the biochemistry of  living cells.  Although the research in these fields aims at modelling and describing collections of biochemical ingredients (molecules) that  evolve by means of reactions, P systems and R systems approach the static and dynamic features of the population of molecules in different ways.   P systems  are based on distributed architectures and operate with multisets,  membrane computing uses  quantitative approaches.   Reaction systems work with sets, and the theory of R  systems employes  qualitative approaches.  In membrane computing, computation and computational power are in focus, whereas R systems theory focuses on evolution. In this talk,  we summarize the basic concepts that separate the two models. We provide  results to compare  these two constructs, and suggest new ideas for future study.

  • E. Formenti, Nice, France. Asynchronous cellular automata

Abstract:

This talk will survey recent results concerned with the dynamical behaviour of asynchronous cellular automata (ACA) and related computational issues. Both the infinite and the finite cases will be covered. Moreover, we will discuss the relationships to other models of computation, including reaction systems. A series of open questions will conclude the talk.

  • N. Jonoska, Tampa, FL, USA. Asynchronous cellular automata

Abstract: TBA.
