  • A Fibonacci sequence for linear structures with two types of components 

    Freixas Bosch, Josep; Molinero Albareda, Xavier; Roura Ferret, Salvador (2009-07-23)
    External research report
    Open Access
    We investigate binary voting systems with two types of voters and a hierarchy among the members in each type, so that members in one class have more influence or importance than members in the other class. The purpose ...
  • An Efficient generic algorithm for the generation of unlabelled cycles 

    Martínez Parra, Conrado; Molinero Albareda, Xavier (2003-06-06)
    External research report
    Open Access
    In this report we combine two recent generation algorithms to obtain a new algorithm for the generation of unlabelled cycles. Sawada's algorithm lists all k-ary unlabelled cycles with fixed content, that is, the number ...
  • Centrality measure in social networks based on linear threshold model 

    Riquelme Csori, Fabián; Gonzalez Cantergiani, Pablo; Molinero Albareda, Xavier; Serna Iglesias, María José (2018-01-15)
    Article
    Restricted access - publisher's policy
    Centrality and influence spread are two of the most studied concepts in social network analysis. In recent years, centrality measures have attracted the attention of many researchers, generating a large and varied number ...
  • Combinatorial structures to construct simple games and molecules 

    Molinero Albareda, Xavier (2017-03-01)
    Article
    Open Access
    We connect three different topics: combinatorial structures, game theory and chemistry. In particular, we establish the bases to represent some simple games, defined as influence games, and molecules, defined ...
  • Combinatorial structures to modeling simple games and applications 

    Molinero Albareda, Xavier (American Institute of Physics (AIP), 2017)
    Conference report
    Open Access
    We connect three different topics: combinatorial structures, game theory and chemistry. In particular, we establish the bases to represent some simple games, defined as influence games, and molecules, defined from atoms, ...
  • Como mejorar el aprendizaje de los grados en ingeniería desde la perspectiva de los estudiantes 

    Navarro Antúnez, Ramón; Molinero Albareda, Xavier (2011)
    Conference report
    Open Access
    La implantación de las nuevas titulaciones derivadas del Espacio Europeo de Educación Superior ha supuesto para las Escuelas de Ingeniería un considerable desafío, no tanto por su contenido o metodología docente, sino ...
  • Complete voting systems with two types of voters: weightedness and counting 

    Freixas Bosch, Josep; Molinero Albareda, Xavier; Roura Ferret, Salvador (2012)
    Article
    Restricted access - author's decision
    We investigate voting systems with two classes of voters, for which there is a hierarchy giving each member of the stronger class more influence or important than each member of the weaker class. We deduce for voting systems ...
  • Computation of several power indices by generating functions 

    Alonso Meijide, José María; Freixas Bosch, Josep; Molinero Albareda, Xavier (2012)
    Article
    Open Access
    In this paper we propose methods to compute the Deegan-Packel, the Public Good, and the Shift power indices by generating functions for the particular case of weighted voting games. Furthermore, we define a new power ...
  • Cooperation through social influence 

    Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (Elsevier, 2015-05-01)
    Article
    Open Access
    We consider a simple and altruistic multiagent system in which the agents are eager to perform a collective task but where their real engagement depends on the willingness to perform the task of other influential agents. ...
  • Dimension and codimension of simple games 

    Kurz, Sascha; Molinero Albareda, Xavier; Olsen, Martin; Serna Iglesias, María José (2016-11-01)
    Article
    Open Access
    This paper studies the complexity of computing a representation of a simple game as the intersection (union) of weighted majority games, as well as, the dimension or the codimension. We also present some examples with ...
  • Forms of representation for simple games: sizes, conversions and equivalences 

    Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (North Holland Mathematical Library, 2015-07-01)
    Article
    Open Access
    Simple games are cooperative games in which the benefit that a coalition may have is always binary, i.e., a coalition may either win or loose. This paper surveys different forms of representation of simple games, and those ...
  • Generic algorithms for the generation of combinatorial objects 

    Molinero Albareda, Xavier; Martínez Parra, Conrado (2003-06)
    External research report
    Open Access
    This report briefly describes our generic approach to the exhaustive generation of unlabelled and labelled combinatorial classes. Our algorithms receive a size n and a finite description of a combinatorial class A using ...
