Image Thresholding with Cell-like P Systems
(Fénix Editora, 2012)
P systems are a new class of distributed parallel computing models. In this paper, a novel three-level thresholding approach for image segmentation based on celllike P systems is proposed in order to improve the computational ...

Computational Efficiency of P Systems with Symport/Antiport Rules and Membrane Separation
(Fénix Editora, 2015)
Membrane ssion is a process by which a biological membrane is split into two new ones in such a way that the contents of the initial membrane is separated and distributed between the new membranes. Inspired by this ...

Solving Problems in a Distributed Way in Membrane Computing: dP Systems
(Fénix Editora, 2010)
Although P systems are distributed parallel computing devices, no explicit way of handling the input in a distributed way in this framework was considered so far. This note proposes a distributed architecture (based on ...

Restricted Polarizationless P Systems with Active Membranes: Minimal Cooperation Only Inwards
(Fenix Editora, 2017)
Membrane computing is a computing paradigm providing a class of distributed parallel computing devices of a biochemical type whose process units represent biological membranes. In the cell-like basic model, a hierarchical ...

The Reduction Problem in CUDA and Its Simulation with P Systems
(Fénix Editora, 2014)
We introduce P systems with dynamic communication graphs which simu- late the functioning of the CUDA architecture when solving the parallel reduction prob- lem.

Towards Bridging Two Cell-Inspired Models: P Systems and R Systems
(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 ...

The Role of the Environment in Tissue P Systems with Cell Division
(Fénix Editora, 2012)
Classical tissue P systems with cell division have a special alphabet whose elements appear at the initial configuration of the system in an arbitrary large number of copies. These objects are shared in a distinguished ...

Limits on P Systems with Proteins and Without Division
(Universidad de Sevilla, Escuela Técnica Superior de Ingeniería Informática, 2018)
In the field of Membrane Computing, computational complexity theory has been widely studied trying to nd frontiers of efficiency by means of syntactic or semantical ingredients. The objective of this is to nd two kinds ...

DCBA: Simulating Population Dynamics P Systems with Proportional Object Distribution
(Fénix Editora, 2012)
Population Dynamics P systems refer to a formal framework for ecological modelling. The semantics of the model associates probabilities to rules, but at the same time, the model is based on P systems, so the rules are ...

Tissue-like P Systems Without Environment
(Fénix Editora, 2010)
In this paper we present a tissue-like P systems model with cell division the environment has been replaced by an extra cell. In such model, we present a uniform family of recognizer P systems which solves the Subset Sum ...
