    • The complexity of measuring power in generalized opinion leader decision models 

      Molinero Albareda, Xavier; Serna Iglesias, María José (2016-10)
      Article
      Accés obert
      We analyze the computational complexity of the power measure in models of collective decision: the generalized opinion leader-follower model and the oblivious and non-oblivious infuence models. We show that computing the ...

    • The complexity of testing properties of simple games 

      Freixas Bosch, Josep; Molinero Albareda, Xavier; Olsen, Martin; Serna Iglesias, María José (2008-04-04)
      Report de recerca
      Accés obert
      Simple games cover voting systems in which a single alternative, such as a bill or an amendment, is pitted against the status quo. A simple game or a yes-no voting system is a set of rules that specifies exactly which ...

    • The neighborhood role in the linear threshold rank on social networks 

      Riquelme Csori, Fabián; Gonzalez Cantergiani, Pablo; Molinero Albareda, Xavier; Serna Iglesias, María José (2019-08-15)
      Article
      Accés obert
      Centrality and influence spread are two of the most studied concepts in social network analysis. Several centrality measures, most of them, based on topological criteria, have been proposed and studied. In recent years new ...

    • Unranking algorithms for combinatorial structures 

      Molinero Albareda, Xavier; Vives Pons, Jordi (2015-12)
      Article
      Accés obert
      We present an implementation of some unlabeled and labeled unranking algorithms for the open-source algebraic combinatorics package MUPAD-COMBINAT of the computer algebra system MUPAD. We have compared our implementation ...

    • Unranking of combinatorial structures 

      Molinero Albareda, Xavier (1997-07)
      Report de recerca
      Accés obert
      The present work is a study of the deterministic generation of combinatorial structures. We generate classes of combinatorial structures formally specifiable by grammars involving unlabelled sequence, unlabelled set, ...

    • Weighted games without a unique minimal representation in integers 

      Freixas Bosch, Josep; Molinero Albareda, Xavier (2009)
      Report de recerca
