El método de reducción en Teoría de la Computabilidad
(2010)
La Teoría de la Computabilidad es una disciplina encuadrada en la Informática Teórica que tiene como objetivo establecer los límites lógicos que presentan los sistemas informáticos a la hora de resolver problemas mediante ...
Strategic Interaction and Conventions
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2010-06)
The scope of the paper is the literature that employs coordination games to study social norms and conventions from the viewpoint of game theory and cognitive psychology. We claim that those two alternative approaches are ...
Lagrangean decomposition for large-scale two-stage stochastic mixed 0-1 problems
(2010-07)
In this paper we study solution methods for solving the dual problem corresponding to the Lagrangean Decomposition of two stage stochastic mixed 0-1 models. We represent the two stage stochastic mixed 0-1 problem by a ...
Majorities with a quorum
(2010-01)
Based on a general model of "quaternary" voting rule, sensitive to voters' choices between four different options (abstaining, voting "yes", voting "no" and staying home), we systematically study different types of majority ...
Quaternary dichotomous voting rules
(2010-01)
In this paper we provide a general model of "quaternary" dichotomous voting rules (QVRs), namely, voting rules for making collective dichotomous decisions (to accept or reject a proposal), based on vote profiles in which ...
Information, stability and dynamics in networks under institutional constraints
(2010-07)
In this paper we study the effects of institutional constraints on stability, efficiency and network formation. More precisely, an exogenous "societal cover" consisting of a collection of possibly overlapping subsets that ...
On downloading and using COIN-OR for solving linear/integer optimization problems
(2010)
The aim of this technical report is to present some detailed explanations in order to help to use the open source software for optimization COIN-OR. In particular, we describe how to download, install and use the corresponding ...
A note on the implementation of the BFC-MSMIP algorithm in C++ by using COIN-OR as an optimization engine
(2010)
The aim of this technical report is to present some detailed explanations in order to help to understand and use the algorithm Branch and Fix Coordination for solving MultiStage Mixed Integer Problems (BFC- MSMIP). We have ...
On solving two stage stochastic linear problems by using a new approach, Cluster Benders Decomposition
(2010-11)
The optimization of stochastic linear problems, via scenario analysis, based on Benders decomposition requires to appending feasibility and/or optimality cuts to the master problem until the iterative procedure reaches the ...
Conditional beta pricing models: A nonparametric approach
(2010)
We propose a two-stage procedure to estimate conditional beta pricing models that allow for flexibility in the dynamics of assets' covariances with risk factors and market prices of risk (MPR). First, conditional covariances ...
