When the El Farol Bar Problem Is Not a Problem? The Role of Social Preferences and Social Networks

چکیده
In this paper, we study the self-coordination problem as demonstrated by the well-known El Farol Bar problem (Arthur, 1994), which later becomes what is known as the Minority Game in the econophysics community. While the El Farol problem or the minority game has been studied for almost two decades, existing studies are most concerned with efficiency only. The equality issue, however, has been largely neglected. In this paper, we build an agent-based model to study both efficiency and equality and ask whether a decentralized society can ever possibly self-coordinate a result with highest efficiency while also maintaining a highest degree of equality. Our agent-based model shows the possibility of achieving this social optimum. The two key determinants to make this happen are social preferences and social networks. Hence, not only does institution (network) matters, but individual characteristics (preferences) also matters. The latter part is open for human-subject experiments for further examination.

With the expansion of social networks, the use of recommender systems in these networks has attracted considerable attention. Recommender systems have become an important tool for alleviating the information that overload problem of users by providing personalized recommendations to a user who might like based on past preferences or observed behavior about one or various items. In these systems...
متن کاملDecision-Making Using Random Boolean Networks In The El Farol Bar Problem
In our daily lives we often face binary decisions where we seek to take either the minority or the majority side. One of these binary decision scenarios is the El Farol Bar Problem, which has been used to study how agents achieve coordination. Previous works have shown that agents may reach appropriate levels of coordination, mostly by looking at their own individual strategies that consider th...

While the MG is born as the mathematical formulation of “El Farol Bar” problem considered by Arthur (1994), it goes way beyond this one, since it generalizes the study of how many individuals may reach a collective solution to a problem under adaptation of each one’s expectations about the future. In Arthur (1994) the “El Farol Bar” problem was posed as an example of inductive reasoning in scen...

An improved particle swarm optimization with a new swap operator for team formation problem
Formation of effective teams of experts has played a crucial role in successful projects especially in social networks. In this paper, a new particle swarm optimization (PSO) algorithm is proposed for solving a team formation optimization problem by minimizing the communication cost among experts. The proposed algorithm is called by improved particle optimization with new swap operator (IPSONSO...
