Hybrid Networks of Evolutionary Processors
(Springer, 2003)
A hybrid network of evolutionary processors consists of several processors which are placed in nodes of a virtual graph and can perform one simple operation only on the words existing in that node in accordance with ...

Characterizing Tractability by Tissue-Like P Systems
(Fénix Editora, 2009)
In the framework of cell–like membrane systems it is well known that the construction of exponential number of objects in polynomial time is not enough to efficiently solve NP–complete problems. Nonetheless, it may be ...

Graphics and P Systems: Experiments with JPLANT
(Fénix Editora, 2008)
The hand-made graphical representation of the configuration of a P system becomes a hard task when the number of membranes and objects increases. In this paper we present a new software tool, called JPLANT, for computing ...

P and dP Automata: A Survey
(Springer, 2011)
This is a quick survey of basic notions and results related to P automata (P systems with symport/antiport rules working in the accepting mode), with some emphasis on the recently introduced dP automata (a distributed ...

The role of the direction in tissue P systems with cell separation
(Institut für Informatik, Justus-Liebig-Universität Giessen, 2014)
Tissue P systems with cell separation where the communication among cells is performed by means of symport and antiport rules are able to efficiently solve computationally hard problems in a feasible time by a space-time ...

A Membrane Computing Model for Ballistic Depositions
(Fénix Editora, 2007)
Ballistic Deposition was proposed by Vold and Sutherland as a model for colloidal aggregation. These early works were later extended to simulate the process of vapor deposition. In general, Ballistic Deposition models ...

Tissue-like P Systems with Channel-States
(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 Functional Astrocytes
(Springer, 2012)
Spiking Neural P Systems (SN P Systems, for short) is a developing field within the universe of P Systems. New variants arise constantly as the study of their properties, such as computational completeness and computational ...

A path to computational efficiency through membrane computing
(Elsevier, 2019)
The search for new mechanisms and tools allowing us to tackle the famousPversusNPproblem from new perspectives is an important task, due to the relevance of that problem.The concept of efficiency of computing models is ...
