Fuzzifying P Systems
Abstract. Uncertainty is an inherent property of all living systems. Curiously enough, computational models inspired by biological systems do not take, in general, under considerat...

P Systems and Finite Automata
Abstract— In this paper, we integrate the traditional finitestate automata (words, or string based) into the membrane computing paradigm, as previous work prevalently concentrat...

P Systems with Active Membranes Characterize PSPACE
P system is a natural computing model inspired by behavior of living cells and their membranes. We show that (semi-)uniform families of P systems with active membranes can solve i...

On the Number of Membranes in Unary P Systems
We consider P systems with a linear membrane structure working on objects over a unary alphabet using sets of rules resembling homomorphisms. Such a restricted variant of P systems...
