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 ...

An Overview of P-Lingua 2.0
(Springer, 2009)
P–Lingua is a programming language for membrane computing which aims to be a standard to define P systems. In order to implement this idea, a Java library called pLinguaCore has been developed as a software framework for ...

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 ...

Uniform solutions to SAT and Subset Sum by spiking neural P systems
(Springer, 2009)
We continue the investigations concerning the possibility of using spiking neural P systems as a framework for solving computationally hard problems, addressing two problems which were already recently considered in this ...

Computing Partial Recursive Functions by Transition P Systems
(Springer, 2004)
In this paper a variant of transition P systems with external output designed to compute partial functions on natural numbers is presented. These P systems are stable under composition, iteration and unbounded minimization ...

Spiking neural P systems with extended rules: universality and languages
(Springer, 2008)
We consider spiking neural P systems with rules allowed to introduce zero, one, or more spikes at the same time. The motivation comes both from constructing small universal systems and from generating strings; previous ...

A fast P system for finding a balanced 2-partition
(Springer, 2005)
Numerical problems are not very frequently addressed in the P systems literature. In this paper we present an effective solution to the 2-Partition problem via a family of deterministic P systems with active membranes ...

On P Systems with Bounded Parallelism
(IEEE Computer Society, 2005)
A framework that describes the evolution of P systems with bounded parallelism is de ned by introducing basic formal features that can be then integrated into a structural operational semantics. This approach investigates ...
