    • 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
      Open Access
      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 ...
    • Coalitional power indices applied to voting systems 

      Molinero Albareda, Xavier; Blasco Ruiz, Joan (2020)
      Conference lecture
      Open Access
      We describe voting mechanisms to study voting systems. The classical power indices applied to simple games just consider parties, players or voters. Here, we also consider games with a priori unions, i.e., coalitions among ...
    • 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 ...
    • Games with multiple alternatives applied to voting systems 

      Blasco Ruiz, Joan; Molinero Albareda, Xavier (Springer, 2020-02)
      Part of book or chapter of book
      Restricted access - publisher's policy
      We describe voting mechanisms to study voting systems as well as electoral systems and parliamentary organizations. These mechanisms are base on the so-called power indices of simple games with alternatives. The classical ...
    • 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 ...
