Towards a Programming Language in Cellular Computing
(Fénix Editora, 2004)
Several solutions to hard numerical problems using P systems have been presented recently, and strong similarities in their designs have been no- ticed. In this paper we present a new solution, an e®ective one to the ...
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 ...
Skeletonizing Images by Using Spiking Neural P Systems
(Fénix Editora, 2012)
Skeletonizing an image is representing a shape with a small amount of information by converting the initial image into a more compact representation and keeping the meaning features. In this paper we use spiking neural ...
A Characterization of PSPACE with Antimatter and Membrane Creation
(Fénix Editora, 2015)
The use of negative information provides a new tool for exploring the limits of P systems as computational devices. In this paper we prove that the combination of antimatter and annihilation rules (based on the annihilation ...
Semantics of Deductive Databases in a Membrane Computing Connectionist Model
The integration of symbolic reasoning systems based on logic and connectionist systems based on the functioning of living neurons is a vivid research area in computer science. In the literature, one can found many e orts ...
Counting Cells with Tissue-like P Systems
(Fénix Editora, 2012)
Counting the number of cells obtained in an experiment is crucial in many areas in Biology. Nonetheless, this is usually performed by hand by the researcher due the intrinsic difficulty of the task. In this paper, we ...
A Cellular Way to Obtain Homology Groups in Binary 2D Images
(Fénix Editora, 2010)
In this paper we present a P systems-based solution for the Homology Groups of Binary 2D Image (HGB2I) Problem, a classical problem in Homology Theory. To this aim, we present a family of P systems which solves all the ...
Solving the 3-COL Problem by Using Tissue P Systems without Environment and Proteins on Cells
The 3-COL problem consists on deciding if the regions of a map can be coloured with only three colors bearing in mind that two adjacent regions must be coloured with di erent colors. It is a NP problem and it has been ...
