    The "Catalytic Borderline" Between Universality and Non-Universality of P Systems  [Presentation]

    Paun, Gheorghe (Fénix Editora, 2013)
    P systems are computing models inspired by the structure and the function- ing of the living cells; they are the basic computing devices of membrane computing, a branch of natural computing. The present note is an overview ...

    Improving Universality Results on Parallel Enzymatic Numerical P Systems  [Presentation]

    Leporati, Alberto; Porreca, Antonio E.; Zandron, Claudio; Mauri, Giancarlo (Fénix Editora, 2013)
    We improve previously known universality results on enzymatic numerical P systems (EN P systems, for short) working in all-parallel and one-parallel modes. By using a attening technique, we rst show that any EN P ...

    Turing Incompleteness of Asynchronous P Systems with Active Membranes  [Presentation]

    Leporati, Alberto; Manzoni, Luca; Porreca, Antonio E. (Fénix Editora, 2013)
    We prove that asynchronous P systems with active membranes without divi- sion rules can be simulated by place/transition Petri nets, and hence are computationally weaker than Turing machines. This result holds even if ...

    An Application of the PCol Automata in Robot Control  [Presentation]

    Langer, Miroslav; Cienciala, Ludek; Ciencialová, Lucie; Perdek, Michal; Kelemenová, Alice (Fénix Editora, 2013)
    The P colonies were introduced in as a variant of the bio-inspired com- putational models called membrane systems or P systems. In we divided agents into the groups according the function they provide; we introduced the ...

    On Controlled P Systems  [Presentation]

    Krithivasan, Kamala; Paun, Gheorghe; Ramanujan, Ajeesh (Fénix Editora, 2013)
    We introduce and brie y investigate P systems with controlled computations. First, P systems with label restricted transitions are considered (in each step, all rules used have either the same label, or, possibly, the ...

    Rete Algorithm for P System Simulators  [Presentation]

    Graciani Díaz, Carmen; Gutiérrez Naranjo, Miguel Ángel; Riscos Núñez, Agustín (Fénix Editora, 2013)
    The Rete algorithm is a well-known algorithm in rule-based production systems which builds directed acyclic graphs that represent higher-level rule sets. This allows the rule-based systems to avoid complete re-evaluation ...

    Universal P Systems: One Catalyst Can Be Suficient  [Presentation]

    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 (computational completeness) by using speci c variants of additional control mechanisms. At each ...
