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.
