We model the problem of contour approximation using Hilbert's space lling curve, with a novel type of parallel array rewriting rules. We further use their pattern to introduce a special type of tissue P system, with ...

In the framework of membrane computing, several frontiers of e ciency have been found with respect to the resources that di erent families of P systems take to solve a decision problem. Each of these frontiers provides ...

Population Dynamics P systems is a modelling framework that have been used successfully for some important real ecosystems. This model is inherently probabilistic, and the scheme of rules is very exible, allowing even ...
