Recognizer P Systems with Antimatter
Díaz Pernil, Daniel; Alhazov, Artiom; Freund, Rudolf; Gutiérrez Naranjo, Miguel Ángel; Leporati, Alberto (Romanian Academy, Section for Information Science and Technology, 2015)In this paper, we consider recognizer P systems with antimatter and the in uence of the matter/antimatter annihilation ...

Red-Green P Automata
Aman, Bogdan; Csuhaj Varjú, Erzsébet; Freund, Rudolf (Fénix Editora, 2014)In this short note we extend the notion of red-green Turing machines to speci c variants of P automata. Acceptance and ...

Self-Stabilization in Membrane Systems
Alhazov, Artiom; Antoniotti, Marco; Freund, Rudolf; Leporati, Alberto; Mauri, Giancarlo (Fénix Editora, 2012)In this paper we study a notion of self-stabilization, inspired from biology and engineering. Multiple variants of ...

Semilinear Sets, Register Machines, and Integer Vector Addition (P) Systems
Alhazov, Artiom; Belingheri, Omar; Freund, Rudolf; Ivanov, Sergiu; Porreca, Antonio E.; Zandron, Claudio (Fénix, 2016)In this paper we consider P systems working with multisets with integer multiplicities. We focus on a model in which rule ...

Sequential P Systems with Unit Rules and Energy Assigned to Membranes
Freund, Rudolf; Leporati, Alberto; Oswald, Marion; Zandron, Claudio (Fénix Editora, 2004)We introduce a new variant of membrane systems where the rules are directly assigned to membranes (and not to the regions ...

Small Universal Antiport P Systems and Universal Multiset Grammars
Freund, Rudolf; Oswald, Marion (Fénix Editora, 2006)Based on the construction of a universal register machine we construct a universal antiport P system working with 31 rules ...

Solving SAT with Antimatter in Membrane Computing
Díaz Pernil, Daniel; Alhazov, Artiom; Freund, Rudolf; Gutiérrez Naranjo, Miguel Ángel (Fénix Editora, 2015)The set of NP-complete problems is split into weakly and strongly NP- complete ones. The di erence consists in the in uence ...

Time-freeness and Clock-freeness and Related Concepts in P Systems
Alhazov, Artiom; Freund, Rudolf; Ivanov, Sergiu; Pan, Linqiang; Song, Bosheng (Fenix Editora, 2017)In the majority of models of P systems, rules are applied at the ticks of a global clock and their products are introduced ...

Tissue P systems with channel states
Freund, Rudolf; Paun, Gheorghe; Pérez Jiménez, Mario de Jesús (Elsevier, 2005)We consider tissue-like P systems with states associated with the links (we call them synapses) between cells, controlling ...

Ponencia
(Tissue) P Systems Using Non-cooperative Rules Without Halting Conditions
Beyreder, Markus; Freund, Rudolf (Fénix Editora, 2008)We consider (tissue) P systems using non-cooperative rules, but considering computations without halting conditions. As ...

(Tissue) P Systems with Anti-Membranes
Alhazov, Artiom; Freund, Rudolf; Ivanov, Sergiu (Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2019)The concept of a matter object being annihilated when meeting its corresponding anti-matter object is taken over for ...

Two Universality Results for (Mem)Brane Systems
Besozzi, Daniela; Busi, Nadia; Franco, Giuditta; Freund, Rudolf; Paun, Gheorghe (Fénix Editora, 2006)We prove that P systems with mate and drip operations and using at most five membranes during any step of a computation ...

Ponencia
Unfair P Systems
Alhazov, Artiom; Freund, Rudolf; Ivanov, Sergiu (Fenix Editora, 2017)We introduce a novel kind of P systems in which the application of rules in each step is controlled by a function on the ...

Ponencia
Universal P Systems: One Catalyst Can Be Suficient
Freund, Rudolf; Paun, Gheorghe (Fénix Editora, 2013)Whether P systems with only one catalyst can already be universal, is still an open problem. Here we establish universality ...

Variants of P Systems with Toxic Objects
Alhazov, Artiom; Freund, Rudolf; Ivanov, Sergiu (Fénix Editora, 2015)Toxic objects have been introduced to avoid trap rules, especially in (purely) catalytic P systems. No toxic object is ...
