Universal P Systems: One Catalyst Can Be Suficient
(Fénix Editora, 2013)
Whether P systems with only one catalyst can already be universal, is still an open problem. Here we establish universality (computational completeness) by using speci c variants of additional control mechanisms. At each ...

The "Catalytic Borderline" Between Universality and Non-Universality of P Systems
(Fénix Editora, 2013)
P systems are computing models inspired by the structure and the function- ing of the living cells; they are the basic computing devices of membrane computing, a branch of natural computing. The present note is an overview ...

On Controlled P Systems
(Fénix Editora, 2013)
We introduce and brie y investigate P systems with controlled computations. First, P systems with label restricted transitions are considered (in each step, all rules used have either the same label, or, possibly, the ...

Bridging Membrane and Reaction Systems - Further Results and Research Topics
(Fénix Editora, 2013)
This paper continues an investigation into bridging two research areas con- cerned with natural computing: membrane computing and reaction systems. More specif- ically, the paper considers a transfer of two assumptions/axioms ...
