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 ...

A new perspective on computational complexity theory in Membrane Computing
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2019)
A single Turing machine can solve decision problems with an in nite number of instances. On the other hand, in the framework of membrane computing, a \solution" to an abstract decision problem consists of a family of ...

New applications for an old tool
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2019)
First, the dependency graph technique, not so far from its current application, was developed trying to nd the shortest computations for membrane systems solving instances of SAT. Certain families of membrane systems ...

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 ...

An optimal solution to the SAT problem with tissue P systems
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2020)
In the framework of membrane computing, several frontiers of e ciency have been found with respect to the resources that di erent families of P systems take to solve a decision problem. Each of these frontiers provides ...

An apparently innocent problem in Membrane Computing
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2019)
The search for effcient solutions of computationally hard problems by means of families of membrane systems has lead to a wide and prosperous eld of research. The study of computational complexity theory in Membrane ...

P Systems: from Anti-Matter to Anti-Rules
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2019)
The concept of a matter object being annihilated when meeting its corresponding anti-matter object is taken over for rule labels as objects and anti-rule labels as the corresponding annihilation counterpart in P systems. ...

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.
