      DCBA: Simulating Population Dynamics P Systems with Proportional Object Distribution  [Presentation]

      Martínez del Amor, Miguel Ángel; Pérez Hurtado de Mendoza, Ignacio; García Quismondo, Manuel; Macías Ramos, Luis Felipe; Valencia Cabrera, Luis; Romero Jiménez, Álvaro; Graciani Díaz, Carmen; Riscos Núñez, Agustín; Colomer, M. Angels; Pérez Jiménez, Mario de Jesús (Fénix Editora, 2012)
      Population Dynamics P systems refer to a formal framework for ecological modelling. The semantics of the model associates probabilities to rules, but at the same time, the model is based on P systems, so the rules are ...
