Inhibiting/De-inhibiting Rules in P Systems
We introduce in the P systems area a mechanism, inspired from neural-cell behavior, which controls computations by inhibiting and de-inhibiting evolution rules. We investigate the ...

Generating Languages by P Systems with Minimal Symport/Antiport
It is known that P systems with two membranes and minimal symport/antiport rules are "almost" computationally complete as generators of number or vector sets. Interpreti...

Partial Halting in P Systems Using Membrane Rules with Permitting Contexts
Abstract. We consider a new variant of the halting condition in P systems, i.e., a computation in a P system is already called halting if not for all membranes a rule is applicable...

On the Number of Membranes in Unary P Systems
We consider P systems with a linear membrane structure working on objects over a unary alphabet using sets of rules resembling homomorphisms. Such a restricted variant of P systems...

On Sequential and 1-Deterministic P Systems
Abstract. The original definition of P-systems calls for rules to be applied in a maximally parallel fashion. However, in some cases a sequential model may be a more reasonable as...
