P Systems with Tables of Rules
(Fénix Editora, 2004)
In the last time, several e®orts were made in order to remove the polarization of membranes from P systems with active membranes; the present paper is a contribution in this respect. In order to compensate the loss of ...

Universal P Systems: One Catalyst Can Be Suficient
(Fénix Editora, 2013)
Whether P systems with only one catalyst can already be universal, is still an open problem. Here we establish universality (computational completeness) by using speci c variants of additional control mechanisms. At each ...

Spiking Neural P Systems with Several Types of Spikes
(Fénix Editora, 2011)
With a motivation related to gene expression, where enzymes act in series, somewhat similar to the train spikes traveling along the axons of neurons, we consider an extension of spiking neural P systems, where several ...

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 { ...

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 ...

Four (Somewhat Nonstandard) Research Topics
(Fénix Editora, 2014)
Four research directions are suggested, dealing with the following four main ideas: computing along the axon (up to now, this topic was only preliminarily investi- gated), using pre-computed resources in order to solve ...
