Looking for Computers in the Biological Cell. After Twenty Years [Presentation]
(Fénix Editora, 2015)
On Communication Complexity in Evolution-Communication P Systems [Presentation]
(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 ...
New Normal Forms for Spiking Neural P Systems [Presentation]
(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 ...
Towards Bridging Two Cell-Inspired Models: P Systems and R Systems [Presentation]
(Fénix Editora, 2011)
We examine, from the point of view of membrane computing, the two basic assumptions of reaction systems, the "threshold" and "no permanence" ones. In certain circumstances (e.g., defining the successful computations by ...
On Controlled P Systems [Presentation]
(Fénix Editora, 2013)
We introduce and brie y investigate P systems with controlled computations. First, P systems with label restricted transitions are considered (in each step, all rules used have either the same label, or, possibly, the ...
Open Problems, Research Topics, Recent Results on Numerical and Spiking Neural P Systems (The "Curtea de Arge s 2015 Series") [Presentation]
A series of open problems and research topics are formulated, about numer- ical and spiking neural P systems, initially prepared as a working material for a three months research stage of the second and the third co-author ...
P Systems with Anti-Matter [Presentation]
(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, ...
Tissue-like P Systems with Channel-States [Presentation]
(Fénix Editora, 2004)
We consider tissue-like P systems with states associated with the links (we call them synapses) between cells, controlling the passage of objects across the links. We investigate the computing power of such devices for ...
Spiking Neural P Systems with Extended Rules [Presentation]
(Fénix Editora, 2006)
We consider spiking neural P systems with spiking rules allowed to introduce zero, one, or more spikes at the same time. The computing power of the obtained systems is investigated, when considering them as number ...
On String Languages Generated by Spiking Neural P Systems [Presentation]
(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 ...
