Using membrane features in P systems.

Abstract

In the basic variant of P systems, membranes are used as separators and as channels of communication. Other variants, introduced to obtain more ``realistic'' models, consider membranes with different features: membranes of variable thickness, electrically charged membranes and active membranes (membranes can be divided to create new membranes). These features are not only useful to obtain ``realistic'' models: we show how we can use them to get simpler and faster models.
