      Cell-like Versus Tissue-like P Systems by Means of Sevilla Carpets  [Presentation]

      Díaz Pernil, Daniel; Gallego Ortiz, Pilar; Gutiérrez Naranjo, Miguel Ángel; Pérez Jiménez, Mario de Jesús; Riscos Núñez, Agustín (Fénix Editora, 2009)
      Sevilla Carpets are a handy tool for comparing computations performed by different systems solving the same problem. Such Sevilla Carpets provide on one hand quantitative information through parameters such as Weight, ...

      Characterizing the Aperiodicity of Irreducible Markov Chains by Using P Systems  [Presentation]

      Cardona, Mónica; Colomer, M. Angels; Pérez Jiménez, Mario de Jesús (Fénix Editora, 2009)
      It is well known that any irreducible and aperiodic Markov chain has exactly one stationary distribution, and for any arbitrary initial distribution, the sequence of distributions at time n converges to the stationary ...

      Characterizing Tractability by Tissue-Like P Systems  [Presentation]

      Gutiérrez Escudero, Rosa; Pérez Jiménez, Mario de Jesús; Rius Font, Miquel (Fénix Editora, 2009)
      In the framework of cell–like membrane systems it is well known that the construction of exponential number of objects in polynomial time is not enough to efficiently solve NP–complete problems. Nonetheless, it may be ...

      Computing Backwards with P Systems  [Presentation]

      Gutiérrez Naranjo, Miguel Ángel; Pérez Jiménez, Mario de Jesús (Fénix Editora, 2009)
      Searching all the configurations C′ such that produce a given configuration C, or, in other words, computing backwards in Membrane Computing is an extremely hard task. The current approximations are based in heavy hand-made ...

      Efficiency of Tissue P Systems with Cell Separation  [Presentation]

      Pan, Linqiang; Pérez Jiménez, Mario de Jesús (Fénix Editora, 2009)
      The most investigated variants of P systems in the last years are cell-like models, especially in terms of efficiency. Recently, different new models of tissue-like (symport/antiport) P systems have received important ...

      P System Based Model of an Ecosystem of the Scavenger Birds  [Presentation]

      Cardona, Mónica; Colomer, M. Angels; Margalida, Antoni; Pérez Hurtado de Mendoza, Ignacio; Pérez Jiménez, Mario de Jesús; Sanuy, Delfí (Fénix Editora, 2009)
      The Bearded Vulture (Gypaetus Barbatus) is an endangered species in Europe that feeds almost exclusively on bone remains provided by wild and domestic ungulates. In, we presented a P system in order to study the evolution ...

      Solving the N-Queens Puzzle with P Systems  [Presentation]

      Gutiérrez Naranjo, Miguel Ángel; Martínez del Amor, Miguel Ángel; Pérez Hurtado de Mendoza, Ignacio; Pérez Jiménez, Mario de Jesús (Fénix Editora, 2009)
      The N-queens puzzle consists on placing N queens on an N x Ngrid in such way that no two queens are on the same row, column or diagonal line. In this paper we present a family of P systems with active membranes (one P ...

      Spiking Neural P Systems with Neuron Division and Budding  [Presentation]

      Pan, Linqiang; Paun, Gheorghe; Pérez Jiménez, Mario de Jesús (Fénix Editora, 2009)
      In order to enhance the e±ciency of spiking neural P systems, we introduce the features of neuron division and neuron budding, which are processes inspired by neural stem cell division. As expected (as it is the case for ...
