    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...

    • Bisemivalues for bicooperative games 

      Domènech Blázquez, Margarita; Giménez Pradales, José Miguel; Puente del Campo, María Albina (2018-02-04)
      Article
      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 as it was given for semivalues in the context ...

      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 ...
