Adding Lifetime to Objects and Membranes in P Systems

Bogdan Aman, Gabriel Ciobanu


Membrane systems are computing devices inspired from the cell functioning. A feature of membrane systems is the fact that objects and membranes are persistent. In fact, this is not quite true in the real world: cells and intracellular proteins have a well-defined lifetime. Inspired from these biological facts, we define a model of membrane systems in which each membrane and each object has attached a lifetime. Some results show that this model is at least as powerful as the usual one.
