A Linear Solution for Subset Sum Problem with Tissue P Systems with Cell Division
(Fénix Editora, 2007)
Tissue P systems are a computing model in the framework of Membrane Computing where the tree-like membrane structure is replaced by a general graph. Recently, it has been shown that endowing these P systems with cell ...

Editing Configurations of P Systems
(Fénix Editora, 2005)
This paper proposes and preliminarily investigates the possibility of transforming a configuration (membrane structure and multisets of symbol-objects present in the compartments of this membrane structure) of a P system ...

Spiking Neural P Systems with Neuron Division and Budding
(Fénix Editora, 2009)
In order to enhance the e±ciency of spiking neural P systems, we introduce the features of neuron division and neuron budding, which are processes inspired by neural stem cell division. As expected (as it is the case for ...

Solving the BINPACKING Problem by Recognizer P Systems with Active Membranes
(Fénix Editora, 2004)
In this paper we present an e®ective solution to the BINPACKING problem using a family of recognizer P systems with active membranes, input membrane and external output. The analysis of the solution presented here will ...

An Approach to the Degree of Parallelism in P Systems
(Fénix Editora, 2006)
In the literature, several designs of P systems were used for performing the same task. The use of different techniques or even different P system models makes it very difficult to compare these designs. In this paper, ...

P System Based Model of an Ecosystem of the Scavenger Birds
(Fénix Editora, 2009)
The Bearded Vulture (Gypaetus Barbatus) is an endangered species in Europe that feeds almost exclusively on bone remains provided by wild and domestic ungulates. In, we presented a P system in order to study the evolution ...

An Efficient Cellular Solution for the Partition Problem
(Fénix Editora, 2004)
Numerical problems are not very frequently addressed in the P sys- tems literature. In this paper we present an e®ective solution to the Partition problem via a family of deterministic P systems with active membranes ...

The Growth of Branching Structures with P Systems
(Fénix Editora, 2006)
L-systems have been widely used to model and graphically represent the growth of plants. In, the use of membrane computing for such tasks has been proposed. In this paper we present a di®erent approach, which makes use ...

Sorting Omega Networks Simulated with P Systems: Optimal Data Layouts
(Fénix Editora, 2008)
The paper introduces some sorting networks and their simulation with P systems, in which each processor/membrane can hold more than one piece of data, and perform operations on them internally. Several data layouts are ...
