Characterizing the Aperiodicity of Irreducible Markov Chains by Using P Systems
(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 ...

Performing Arithmetic Operations with Spiking Neural P Systems
(Fénix Editora, 2009)
We consider spiking neural P systems as devices which can be used to perform some basic arithmetic operations, namely addition, subtraction, comparison and multiplication by a fixed factor. The input to these systems are ...

A First Model for Hebbian Learning with Spiking Neural P Systems
(Fénix Editora, 2008)
Spiking neural P systems and artificial neural networks are computational devices which share a biological inspiration based on the transmission of information among neurons. In this paper we present a first model for ...

Testing Einstein’s Formula on Brownian Motion Using Membrane Computing
(Fénix Editora, 2008)
Brownian motion refers to erratic movements of small particles of solid matter suspended in a fluid and it is the basis of the development of many fractals found in Nature. In this paper we use the Membrane Computing ...

Efficiency of Tissue P Systems with Cell Separation
(Fénix Editora, 2009)
The most investigated variants of P systems in the last years are cell-like models, especially in terms of efficiency. Recently, different new models of tissue-like (symport/antiport) P systems have received important ...

Uniform Solution to QSAT Using Polarizationless Active Membranes
(Fénix Editora, 2006)
It is known that the satisfiability problem (SAT) can be solved a semi- uniform family of deterministic polarizationless P systems with active membranes with non-elementary membrane division. We present a double improvement ...

Characterizing Tractability by Tissue-Like P Systems
(Fénix Editora, 2009)
In the framework of cell–like membrane systems it is well known that the construction of exponential number of objects in polynomial time is not enough to efficiently solve NP–complete problems. Nonetheless, it may be ...

Graphics and P Systems: Experiments with JPLANT
(Fénix Editora, 2008)
The hand-made graphical representation of the configuration of a P system becomes a hard task when the number of membranes and objects increases. In this paper we present a new software tool, called JPLANT, for computing ...
