Tackling the Computational Complexity of Understanding Coalition Formation in Multi-agent Systems, Andrew Dowell In its simplest metaphor, agent based computation is that undertaken via the interactions of autonomous computational entities (from [39]). Often, these interactions are cooperative and, in this context, a coalition describes any group of agents who may cooperate together. In any mul...

If modal logics for coalitions need to be applied, one must know how to translate coalition power into agents’ actions. To these days, the connection between coalition power and the actions of the agents has not been studied in the literature. This paper fills the gap by presenting a semantic translation from Pauly’s Coalition Logic to a (fragment of an) action logic. The interpretation of the ...

The study of a decentralized coalition formation scheme in an speci c Power Systems transmission expansion scenario is the purpose of this paper. We dene rst who are the players in the expansion game, and provide a decentralized coalition scheme based on Bilateral Shapley Values. We study the stability properties of our approach to allocate expansion costs to all coalition members. Finally, the...

Pre-electoral coalitions (PECs) are one of the most often used methods to coordinate entry into the electoral market. Party elites, however, do not know how voters will respond to the coalition formation at the polls. In this article, the authors report on an experimental study among 1,255 Belgian students. In order to study voter responses to the formation of PECs, respondents were presented w...

In vehicular-to-roadside (V2R) communications of vehicular network, the bandwidth from roadside unit (RSU) can be shared among vehicular users to improve the utilization and reduce the cost. In this paper, the coalition game is formulated to model the situation in which multiple vehicular users can cooperate to share the bandwidth to RSU. First, the rational coalition formation is considered in...

This paper studies an incentive structure for cooperation and its stability in peer-assisted services when there exist multiple content providers, using a coalition game theoretic approach. We first consider a generalized coalition structure consisting of multiple providers with many assisting peers, where peers assist providers to reduce the operational cost in content distribution. To distrib...

As the trend in electricity markets is strongly towards deregulation, new players, new rules and new behaviors will continue to emerge. One of the new phenomena that are developing on the demand side is the purchase by a coalition of agents. When it is worth, a coalition will be constituted. One of the energy needs, especially important in Nordic countries such as Finland, is electrical space h...

BACKGROUND The Coalition for Health Access to Reach Greater Equity (Project CHARGE) is a health policy advocacy coalition devoted to improving healthcare access for Asian Americans in New York City. OBJECTIVES This paper discusses Project CHARGE's strategies for building a successful coalition. METHODS Findings are based on evaluation data from field observations and surveys of Coalition re...
