Minimal Parallelism for Polarizationless P Systems
Minimal parallelism was recently introduced [3] as a way the rules of a P system are used: from each set of applicable rules associated to the same membrane, at least one must be a...

On a Powerful Class of Non-universal P Systems with Active Membranes
Abstract. We prove that uniform and semi-uniform families of P systems with active membranes using only communication and nonelementary division rules are not computationally unive...

P systems with active membranes: trading time for space
We consider recognizer P systems having three polarizations associated to the membranes, and we show that they are able to solve the PSPACEcomplete problem Quantified 3SAT when wo...

Active Membrane Systems Without Charges and Using Only Symmetric Elementary Division Characterise P
In this paper we introduce a variant of membrane systems with elementary division and without charges. We allow only elementary division where the resulting membranes are identical...
