Numerical problems are not very frequently addressed in the P sys- tems literature. In this paper we present an e®ective solution to the Partition problem via a family of deterministic P systems with active membranes ...

We present in this paper a simulation with P systems of the parallel architecture known as shuffle-exchange network. This will lead us to consider a new version of P systems with communication, for which the communicat ...

In this paper we present a first approach to the definition of different entropy measures for probabilistic P systems in order to obtain some quantitative parameters showing how complex the evolution of a P system is. To ...

In the last time, several e®orts were made in order to remove the polarization of membranes from P systems with active membranes; the present paper is a contribution in this respect. In order to compensate the loss of ...

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 ...

In tissue P systems several cells (elementary membranes) commu- nicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell) P systems with active membranes { ...

In this paper we propose a new way to represent recognizer P systems with active membranes based on Production Systems techniques. This representation allows us to express the set of rules and the configurations in each ...

In this paper we present an e®ective solution to the BINPACKING problem using a family of recognizer P systems with active membranes, input membrane and external output. The analysis of the solution presented here will ...

In computational processes based on backwards chaining, a rule of the type A Ã B1; : : : ;Bn is seen as a procedure which points that the problem A can be split into the problems B1; : : : ;Bn. In classical devices, the ...

Software simulators for P system are nowadays the main tool to carry out experiments in the field of Membrane Computing. Although the simulation of a P system is a quite complex task, current simulators have been ...
