El grup té una experiència de gairebé vint anys en el seu camp d’expertesa, la teoria de jocs i les seves aplicacions, des d’aleshores fins ara el grup ha mantingut una línia creixent tant pel que fa a la producció científica contrastada com al nombre de membres que l’integren. El grup és avui un referent internacional en àrees específiques com ara els sistemes de votació i els jocs cooperatius així com en les seves aplicacions: tecnològiques, econòmiques, polítiques i sociològiques.

Els seus treballs són matemàticament rigorosos i concisos, i els seus membres són bons coneixedors de l’àlgebra, la matemàtica discreta, la probabilitat o la computació. Nombroses situacions extretes de la vida quotidiana els han estimulat a modelitzar, simular i proposar propostes de solució o de millora.

Els seus membres comparteixen nombroses publicacions de prestigi, vetllen per la creixent internacionalització del grup, tenen cura de la formació i divulguen els seus treballs.

Research in the foundations and applications of game theory. The main theoretical lines are the following: (a) cooperative games and solution concepts; (b) collective decision-making mechanisms and power indices; (c) restrictions to cooperation; (d) multiplicity of alternatives; and (e) software. The areas of application include economics, political science, sociology, management, industrial scheduling and technologies such as cryptography and reliability.

  • On alpha-roughly weighted games 

    Freixas Bosch, Josep; Kurz, Sascha (2011-12-13)
    Report de recerca
    Accés obert
    Very recently Gvozdeva, Hemaspaandra, and Slinko (2011) h ave introduced three hierarchies for simple games in order to measure the distance of a given simple game to the class of weighted voting games or roughly weighted ...
  • 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 ...
  • Weighted voting, abstention and multiple levels of approval 

    Freixas Bosch, Josep; Zwicker, William S. (Springer, 2003-12)
    Article
    Accés obert
    In this paper we introduce the class of simple games with several ordered levels of approval in the input and in the output – the ( j,k) simple games – and propose a definition for weighted games in this context. Abstention ...
  • Ability to separate situations with a priori coalition structures by means of symmetric solutions 

    Giménez Pradales, José Miguel (2017)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    We say that two situations described by cooperative games are inseparable by a family of solutions, when they obtain the same allocation by all solution concept of this family. The situation of separability by a family of ...
  • Effect of a science communication event on students’ attitudes towards science and technology

  • A new procedure to calculate the Owen value 

    Puente del Campo, María Albina; Giménez Pradales, José Miguel (2017)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    In this paper we focus on games with a coalition structure. Particularly, we deal with the Owen value, the coalitional value of the Shapley value, and we provide a computational procedure to calculate this coalitional value ...
  • Measuring satisfaction in societies with opinion leaders and mediators 

    Molinero Albareda, Xavier; Riquelme Csori, F.; Serna Iglesias, María José (2016-05-14)
    Report de recerca
    Accés obert
    An opinion leader-follower model (OLF) is a two-action collective decision-making model for societies, in which three kinds of actors are considered:
  • Decisiveness indices are semiindices: addendum 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (2017-01-01)
    Article
    Accés restringit per política de l'editorial
    In the paper Decisiveness indices are semiindices (Freixas and Pons, 2016) it was shown that any decisiveness index obtained from an anonymous probability distribution is a semiindex, and that the converse is not true. In ...
  • On the construction of high dimensional simple games 

    Olsen, Martin; Kurz, Sascha; Molinero Albareda, Xavier (IOS Press, 2016)
    Text en actes de congrés
    Accés obert
    Voting is a commonly applied method for the aggregation of the preferences of multiple agents into a joint decision. If preferences are binary, i.e., “yes” and “no”, every voting system can be described by a (monotone) ...
  • Dimension and codimension of simple games 

    Kurz, Sascha; Molinero Albareda, Xavier; Olsen, Martin; Serna Iglesias, María José (2016-11-01)
    Article
    Accés restringit per política de l'editorial
    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 ...
