  • 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

    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 ...
  • 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. ...
  • 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 ...
  • Measuring satisfaction and power in influence based decision systems 

    Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (2019-06-15)
    Article
    Restricted access - publisher's policy
    We introduce collective decision-making models associated with influence spread under the linear threshold model in social networks. We define the oblivious and the non-oblivious influence models. We also introduce the ...
  • Power indices of influence games and new centrality measures for agent societies and social networks 

    Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (Springer, 2014-06)
    Article
    Open Access
    We propose as centrality measures for social networks two classical power indices, Banzhaf and Shapley-Shubik, and two new measures, effort and satisfaction, related to the spread of influence process that emerge from the ...
  • Satisfaction and power in unanimous majority influence decision models 

    Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (2018-07)
    Article
    Restricted access - publisher's policy
    We consider decision models associated with cooperative influence games, the oblivious and the non-oblivious influence models. In those models the satisfaction and the power measures were introduced and studied. We analyze ...
  • Star-shaped mediation in influence games 

    Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (2013)
    Conference lecture
    Open Access
    We are interested in analyzing the properties of multi-agent systems [13] where a set of agents have to take a decision among two possible alternatives with the help of the social environment or network of the system itself. ...
  • Structural and computational aspects of simple and influence games 

    Riquelme Csori, Fabián (Universitat Politècnica de Catalunya, 2014-07-29)
    Doctoral thesis
    Open Access
    Simple games are a fundamental class of cooperative games. They have a huge relevance in several areas of computer science, social sciences and discrete applied mathematics. The algorithmic and computational complexity ...
