Polarizationless P Systems with Active Membranes Working in the Minimally Parallel Mode
(Fénix Editora, 2007)
We investigate the computing power and the efficiency of P systems with active membranes without polarizations, working in the minimally parallel mode. We prove that such systems are computationally complete and able to ...

Tissue P Systems with Cell Division
(Fénix Editora, 2004)
In tissue P systems several cells (elementary membranes) commu- nicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell) P systems with active membranes { ...

New Normal Forms for Spiking Neural P Systems
(Fénix Editora, 2009)
We consider a natural restriction in the architecture of a spiking neural P system, namely, to have neurons of a small number of types (i.e., using a small number of sets of rules), and we prove that three types of neurons ...

Spiking Neural P Systems with Anti-Spikes
(Fénix Editora, 2009)
Besides usual spikes employed in spiking neural P systems, we consider "anti-spikes", which participate in spiking and forgetting rules, but also annihilate spikes when meeting in the same neuron. This simple extension ...

P Systems with Anti-Matter
(Fénix Editora, 2014)
After a short introduction to the area of membrane computing (a branch of natural computing), we introduce the concept of anti-matter in membrane computing. First we consider spiking neural P systems with anti-spikes, ...

On String Languages Generated by Spiking Neural P Systems
(Fénix Editora, 2006)
We continue the study of spiking neural P systems by considering these computing devices as binary string generators: the set of spike trains of halting computations of a given system constitutes the language generated ...

On Communication Complexity in Evolution-Communication P Systems
(Fénix Editora, 2010)
Looking for a theory of communication complexity for P systems, we consider here so-called evolution-communication (EC for short) P systems, where objects evolve by multiset rewriting rules without target commands and ...

Notes About Spiking Neural P Systems
(Fénix Editora, 2011)
Spiking neural P systems (SN P systems, for short) are much investigated in the last years in membrane computing, but still many open problems and research topics are open in this area. Here, we first recall two such ...
