From membranes to systems: self-configuration and self-replication in membrane systems.

Membrane systems are purely abstract computational models afar inspired by biological cells, their membranes, and their biochemistry. The inherently parallel nature of membrane systems makes them obviously highly inefficient to execute on a sequential von Neumann computer architecture and in addition, programming a membrane system is often a painstakingly difficult undertaking. The main goal of this paper is to provide some key elements for bringing membrane systems from the abstract model closer to a genuine, novel, and unconventional in silico computer architecture. In particular, we will address the mechanisms of self-configuration and self-replication on a macroscopic level and will discuss some general issues related to genuine hardware realizations on the microscopic level.
