LMNtal: A Language Model with Links and Membranesrchies. The two major goals of LMNtal are (i) to unify various computational models based on multiset rewriting and (ii) to serve as the basis of a truly general-purpose language covering various platforms ranging from wide-area to embedded computation. Another important contribution of the model is

FATAL

Executable Specifications of P Systemsing and equational logic. We define the P system maximal parallel evolution as a specific rewriting strategy in Maude. By extending the Maude rewriting semantics with this strategy, we provide an operational semantics of the P systems. We present few examples of specifying and executing simple P sys

Communicative P Systems with Minimal Cooperationze 1 and and P systems with symport rules of size 2, are computationally complete: they generate all recursively enumerable sets of vectors of nonnegative integers. The result of computation is obtained in the elementary membrane.

A P System Description of the Sodium-Potassium Pump the formal framework of P systems, considered here as tools for modelling a bio-cellular process. New features such as variable membrane labelling, activation conditions for rules, membrane bilayer and specific communication rules are defined, to the aim of providing a more appropriate description

啪心兒跳動

Inhibiting/De-inhibiting Rules in P Systemsion rules. We investigate the computational power of this mechanism in both generative and accepting P systems. In particular, we prove that universality can be obtained by using one catalyst. If we use only non-cooperative rules and one membrane, then we can obtain at least the family of Parikh ima

Exploring Computation Trees Associated with P Systemsbranches in this tree may differ significantly from a computational complexity point of view, that is, for the amount of time and storage necessary to reach a result. In this paper we propose a first approach to outline a strategy for selecting a suitable branch, in some sense, of the computation tr
