Cell-like Versus Tissue-like P Systems by Means of Sevilla Carpets [Presentation]
(Fénix Editora, 2009)
Sevilla Carpets are a handy tool for comparing computations performed by different systems solving the same problem. Such Sevilla Carpets provide on one hand quantitative information through parameters such as Weight, ...
Characterizing the Aperiodicity of Irreducible Markov Chains by Using P Systems [Presentation]
(Fénix Editora, 2009)
It is well known that any irreducible and aperiodic Markov chain has exactly one stationary distribution, and for any arbitrary initial distribution, the sequence of distributions at time n converges to the stationary ...
P-Lingua 2.0: New Features and First Applications [Presentation]
(Fénix Editora, 2009)
P-Lingua is a programming language for membrane computing. It was rst presented in Edinburgh, during the Ninth Workshop on Membrane Computing (WMC9). In this paper, the models, simulators and formats included in P-Lingua ...
P System Based Model of an Ecosystem of the Scavenger Birds [Presentation]
(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 ...
Solving the N-Queens Puzzle with P Systems [Presentation]
(Fénix Editora, 2009)
The N-queens puzzle consists on placing N queens on an N x Ngrid in such way that no two queens are on the same row, column or diagonal line. In this paper we present a family of P systems with active membranes (one P ...
Towards Probabilistic Model Checking on P Systems Using PRISM [Chapter of Book]
(Springer, 2006)
This paper presents the use of P systems and π-calculus to model interacting molecular entities and how they are translated into a probabilistic and symbolic model checker called PRISM.
Graphical Modeling of Higher Plants Using P Systems [Chapter of Book]
(Springer, 2006)
L systems have been widely used to model and graphically represent the growth of higher plants [20]. In this paper we continue developing the framework introduced in [21], which make use of the topology of membrane ...
Linear Time Solution to Prime Factorization by Tissue P Systems with Cell Division [Presentation]
(Fénix Editora, 2011)
Prime factorization is useful and crucial for public-key cryptography, and its application in public-key cryptography is possible only because prime factorization has been presumed to be difficult. A polynomial-time ...
A Linear-Time Solution to the Knapsack Problem Using P Systems with Active Membranes [Chapter of Book]
(Springer, 2004)
Up to now, P systems dealing with numerical problems have been rarely considered in the literature. In this paper we present an effective solution to the Knapsack problem using a family of deterministic P systems with ...
A P System Modeling an Ecosystem Related to the Bearded Vulture [Presentation]
(Fénix Editora, 2008)
The Bearded Vulture is one of the rarest raptors in Europe and it is an endangered species. In this paper, we present a model of an ecosystem related with the Bearded Vulture which is located in the Catalan Pyrenees, by ...
