  • Ability to separate situations with a priori coalition structures by means of symmetric solutions 

    Giménez Pradales, José Miguel (2017)
    Conference lecture
    Restricted access - publisher's policy
    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 ...
  • Accessibility measures to nodes of directed graphs using solutions for generalized cooperative games 

    Amer Ramon, Rafael; Giménez Pradales, José Miguel; Magaña Nieto, Antonio (2012-02)
    Article
    Restricted access - publisher's policy
    The aim of this paper consists of constructing accessibility measures to the nodes of directed graphs using methods of Game Theory. Since digraphs without a predefined game are considered, the main part of the paper is ...
  • A concept of weighted connectivity on connected graphs 

    Amer Ramon, Rafael; Giménez Pradales, José Miguel (2009-02)
    Article
    Open Access
    The introduction of a {0,1}-valued game associated to a connected graph allows us to assign to each node a value of weighted connectivity to the different solutions that for the cooperative games are obtained by means of ...

  • A method to calculate generalized mixed modified semivalues: application to the Catalan Parliament (legislature 2012-2016) 

    Giménez Pradales, José Miguel; Puente del Campo, María Albina (Springer, 2015-10-01)
    Article
    Open Access
    We focus on generalized mixed modified semivalues, a family of coalitional values. They apply to games with a coalition structure by combining a (induced) semivalue in the quotient game, but share within each union the ...
  • A new procedure to calculate the Owen value 

    Puente del Campo, María Albina; Giménez Pradales, José Miguel (2017)
    Conference lecture
    Restricted access - publisher's policy
    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 ...
  • Aportaciones al estudio de soluciones para juegos cooperativos 

    Giménez Pradales, José Miguel (Universitat Politècnica de Catalunya, 2001-12-14)
    Doctoral thesis
    Open Access
    El objetivo del trabajo consiste en la generalización y el estudio de modelos y métodos que han mostrado su eficiencia respecto a las soluciones para los juegos cooperativos propuestas por Shapley o por Banzhaf, así como ...
  • A probabilistic concept of accessibility for access structures 

    Amer Ramon, Rafael; Giménez Pradales, José Miguel; Magaña Nieto, Antonio (2008-06-13)
    External research report
    Open Access
    In this paper we introduce the concept of weighted accessibility for access structures. In some sense, it represents a measure of how difficult or how easy is to recover the secret. We give also a numerical measure of ...
  • Bisemivalues, binomial bisemivalues and multilinear extension for bicooperative games 

    Domènech Blázquez, Margarita; Giménez Pradales, José Miguel; Puente del Campo, María Albina (2015-10-05)
    External research report
    Open Access
    We introduce bisemivalues for bicooperative games and we also provide an interesting characterization of this kind of values by means of weighting coefficients in a similar way than given for semivalues in the context of ...

  • Computational procedure for a wide family of mixed coalitional values 

    Giménez Pradales, José Miguel; Puente del Campo, María Albina (2015)
    Conference report
    Restricted access - publisher's policy
    We consider a family of mixed coalitional values. They apply to games with a coalition structure by combining a (induced) semivalue in the quotient game, but share within each union the payoff so obtained by applying ...
  • Cooperative games with a priori unions: introduction of a wide set of solutions 

    Giménez Pradales, José Miguel (2006-12-04)
    External research report
    Open Access
    The semivalues are solution concepts for cooperative games that assign to each player a weighted sum of his/her marginal contributions to the coalitions, where the weights only depend on the coalition size. The Shapley ...
