Attacking the Common Algorithmic Problem by Recognizer P Systems
(Springer, 2005)
Many NP-complete problems can be viewed as special cases of the Common Algorithmic Problem (CAP). In a precise sense, which will be defined in the paper, one may say that CAP has a property of local universality. In ...

Modelling Vibrio fischeri’s behaviour Using P Systems
(2005)
Quorum sensing is a cell density dependent gene regulation system that allows an entire population of bacterial cells to communicate in order to regulate the expression of certain or specific genes in a coordinated way ...

A CLIPS Simulator for Recognizer P Systems with Active Membranes
(Fénix Editora, 2004)
In this paper we propose a new way to represent recognizer P systems with active membranes based on Production Systems techniques. This representation allows us to express the set of rules and the configurations in each ...

Trading Polarization for Bi-stable Catalysts in P Systems with Active Membranes
(Springer, 2005)
In the last time, several efforts have been made in order to remove polarizations of membranes from P systems with active membranes; the present paper is a contribution in this respect. In order to compensate the loss ...

On P Systems as a Modelling Tool for Biological Systems
(Springer, 2006)
We introduce a variant of P systems where rules have associated a real number providing a measure for the “intrinsic reactivity”of the rule and roughly corresponding to the kinetic coefficient which, in bio-chemistry, ...

A Linear Solution for QSAT with Membrane Creation
(Springer, 2006)
The usefulness of P systems with membrane creation for solving NP problems has been previously proved (see [2, 3]), but, up to now, it was an open problem whether such P systems were able to solve PSPACE-complete problems ...

On the Power of Dissolution in P Systems with Active Membranes
(Springer, 2006)
In this paper we study membrane dissolution rules in the framework of P systems with active membranes but without using electrical charges. More precisely, we prove that the polynomial computational complexity class ...

Solving SAT with membrane creation
(University of Amsterdam, 2005)
Membrane Computing is a branch of Natural Computing which starts from the assumption that the processes taking place in the compartmental structure of a living cell can be interpreted as computations. In this paper we ...

Characterizing Tractability with Membrane Creation
(IEEE Computer Society, 2005)
This paper analyzes the role that membrane dissolution rules play in order to characterize (in the framework of recognizer P systems with membrane creation) the tractability of decision problems that is, the ef cient ...

A Modeling Approach Based on P Systems with Bounded Parallelism
(Springer, 2006)
This paper presents a general framework for modelling with membrane systems that is based on a computational paradigm where rules have associated a finite set of attributes and a corresponding function. Attributes and ...
