Editing Configurations of P Systems
(Fénix Editora, 2005)
This paper proposes and preliminarily investigates the possibility of transforming a configuration (membrane structure and multisets of symbol-objects present in the compartments of this membrane structure) of a P system ...

Maximum Search Using P Systems
(Fénix Editora, 2004)
Several algorithms of maximum search are investigated and eval- uated in different types of P systems, namely using priorities, multiple nested membranes and linked transport. The proposed solutions are expected to ...

Mutation Based Testing of P Systems
(Fénix Editora, 2009)
Although testing is an essential part of software development, until recently, P system testing has been completely neglected. Mutation testing (mutation analysis) is a structural software testing method which involves ...

P Systems with Adjoining Controlled Communication Rules
(Fénix Editora, 2007)
This paper proposes a new model of P systems where the rules are activated by objects present in the neighboring regions. We obtain the computational completeness considering only two membranes, external inhibitors and ...

Modeling Reaction Kinetics in Low-dimensional Environments with Conformon P Systems: Comparison with Cellular Automata and New Rate Laws
(Fénix Editora, 2009)
Recently it has been shown that simulations of complex biological systems using conformon P systems and cellular automata do not necessarily give the same pre- dictions. To further elucidate these di®erences we simulate ...

Three Quantum Algorithms to Solve 3-SAT
(Fénix Editora, 2006)
We propose three quantum algorithms to solve the 3-SAT NP-complete decision problem. The first algorithm builds, for any instance Á of 3-SAT, a quantum Fredkin circuit that computes a superposition of all classical ...

Spiking Neural P Systems with Neuron Division and Budding
(Fénix Editora, 2009)
In order to enhance the e±ciency of spiking neural P systems, we introduce the features of neuron division and neuron budding, which are processes inspired by neural stem cell division. As expected (as it is the case for ...
