A Fibonacci sequence for linear structures with two types of components
(2009-07-23)
Research report
Open AccessWe investigate binary voting systems with two types of voters and a hierarchy among the members in each type, so that members in one class have more influence or importance than members in the other class. The purpose ... -
An Efficient generic algorithm for the generation of unlabelled cycles
(2003-06-06)
Research report
Open AccessIn this report we combine two recent generation algorithms to obtain a new algorithm for the generation of unlabelled cycles. Sawada's algorithm lists all k-ary unlabelled cycles with fixed content, that is, the number ... -
Analytical study on typeface visual identification
(SciTePress, 2024)
Conference report
Open AccessIn this study, our objective is to explore methodologies for the identification of diverse typefaces. Utilizing the gathered data, we conducted a thorough analysis of the outcomes, distinguishing between successes and ... -
Centrality measure in social networks based on linear threshold model
(2018-01-15)
Article
Open AccessCentrality and influence spread are two of the most studied concepts in social network analysis. In recent years, centrality measures have attracted the attention of many researchers, generating a large and varied number ... -
Coalitional power indices applied to voting systems
(2020)
Conference lecture
Open AccessWe describe voting mechanisms to study voting systems. The classical power indices applied to simple games just consider parties, players or voters. Here, we also consider games with a priori unions, i.e., coalitions among ... -
Combinatorial structures to construct simple games and molecules
(2017-03-01)
Article
Open AccessWe connect three different topics: combinatorial structures, game theory and chemistry. In particular, we establish the bases to represent some simple games, defined as influence games, and molecules, defined ... -
Combinatorial structures to modeling simple games and applications
(American Institute of Physics (AIP), 2017)
Conference report
Open AccessWe connect three different topics: combinatorial structures, game theory and chemistry. In particular, we establish the bases to represent some simple games, defined as influence games, and molecules, defined from atoms, ... -
Como mejorar el aprendizaje de los grados en ingeniería desde la perspectiva de los estudiantes
(2011)
Conference report
Open AccessLa implantación de las nuevas titulaciones derivadas del Espacio Europeo de Educación Superior ha supuesto para las Escuelas de Ingeniería un considerable desafío, no tanto por su contenido o metodología docente, sino ... -
Complete voting systems with two types of voters: weightedness and counting
(2012)
Article
Restricted access - author's decisionWe investigate voting systems with two classes of voters, for which there is a hierarchy giving each member of the stronger class more influence or important than each member of the weaker class. We deduce for voting systems ... -
Computation of several power indices by generating functions
(2012)
Article
Open AccessIn this paper we propose methods to compute the Deegan-Packel, the Public Good, and the Shift power indices by generating functions for the particular case of weighted voting games. Furthermore, we define a new power ... -
Cooperation through social influence
(Elsevier, 2015-05-01)
Article
Open AccessWe consider a simple and altruistic multiagent system in which the agents are eager to perform a collective task but where their real engagement depends on the willingness to perform the task of other influential agents. ... -
Dimension and codimension of simple games
(2016-11-01)
Article
Open AccessThis 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 ... -
Extremal coalitions for influence games through swarm intelligence-based methods
(2022)
Article
Open AccessAn influence game is a simple game represented over an influence graph (i.e., a labeled, weighted graph) on which the influence spread phenomenon is exerted. Influence games allow applying different properties and parameters ... -

Forms of representation for simple games: sizes, conversions and equivalences
(North Holland Mathematical Library, 2015-07-01)
Article
Open AccessSimple games are cooperative games in which the benefit that a coalition may have is always binary, i.e., a coalition may either win or loose. This paper surveys different forms of representation of simple games, and those ... -
Games with multiple alternatives applied to voting systems
(Springer, 2020-02)
Part of book or chapter of book
Restricted access - publisher's policyWe describe voting mechanisms to study voting systems as well as electoral systems and parliamentary organizations. These mechanisms are base on the so-called power indices of simple games with alternatives. The classical ... -
Generic algorithms for the generation of combinatorial objects
(2003-06)
Research report
Open AccessThis report briefly describes our generic approach to the exhaustive generation of unlabelled and labelled combinatorial classes. Our algorithms receive a size n and a finite description of a combinatorial class A using ... -
Help to new students of ICT Systems Engineering Degree at EPSEM-UPC: mentoring
(Universitat Politècnica de Catalunya. Institut de Ciències de l'Educació, 2014-05)
Article
Open AccessFreshmen at the Manresa School of Engineering, Escola Politècnica Superior d'Enginyeria de Manresa (EPSEM), of the Universitat Politècnica de Catalunya (UPC) are voluntarily provided with the mentoring service during their ... -

Influence decision models: from cooperative game theory to social network analysis
(Elsevier, 2021-02)
Article
Open AccessCooperative game theory considers simple games and influence games as essential classes of games. A simple game can be viewed as a model of voting systems in which a single alternative, such as a bill or an amendment, is ...
