      Gorchs Altarriba, Roser; Molinero Albareda, Xavier; Garriga Sucarrats, Salvador (2013)
      Article
      Accés obert
      This work details the coaching (mentoring) at Manresa School of Engineering (Escola Politècnica Superior d'Enginyeria de Manresa). It considers the evolution from the beginning (course 2009-10) to the present. Each course ...

    • 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
      Accés obert
      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 ...

      Molinero Albareda, Xavier (1998-06-30)
      Report de recerca
      Accés obert
      Donada una classe d'estructures combinatòries A, fixada una talla n i considerant un ordre total definit prèviament, la funció que ens determina l'i-èsim objecte corresponent s'anomena unrank. Estudiarem els avantatges i ...

    • Recolzament als nous estudiants del grau d’Enginyeria de sistemes TIC en l’EPSEM –UPC: la mentoria 

      Gorchs Altarriba, Roser; Molinero Albareda, Xavier (Universitat de Girona. Servei de Publicacions, 2013)
      Comunicació de congrés
      Accés obert
      Als estudiants de nou ingrés a l'Escola Politècnica Superior d'Enginyeria de Manresa (EPSEM) de la UPC se'ls proporciona voluntàriament

    • Satisfaction and power in unanimous majority influence decision models 

      Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (2018-07)
      Article
      Accés obert
      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 ...

    • Simple games and weighted games: a theoretical and computational viewpoint 

      Freixas Bosch, Josep; Molinero Albareda, Xavier (2009-04)
      Article
      Accés restringit per política de l'editorial

    • Social disruption games in signed networks 

      Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (2024-05)
      Article
      Accés restringit per política de l'editorial
      Signed networks describe many real-world relations among users. Positive connections between two users or vertices generally mean good feelings between them, but negative connections mean bad feelings. A disruptor cycle ...

    • Software matemàtic lliure 

      Molinero Albareda, Xavier (Escola Politècnica Superior d’Enginyeria de Manresa, 2010-12-02)

    • Some advances in the theory of voting systems based on experimental algorithms 

      Freixas Bosch, Josep; Molinero Albareda, Xavier (2006-01)
      Report de recerca
      Accés obert
      In voting systems, game theory, switching functions, threshold logic, hypergraphs or coherent structures there is an important problem that consists in determining the weightedness of a voting system by means of trades ...

    • Star-shaped mediation in influence games 

      Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (2013)
      Comunicació de congrés
      Accés obert
      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. ...

    • 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 ...
