Robust Coalition Structure Generation
2018How to form effective coalitions is an important issue in multi-agent systems. Coalition Structure Generation (\(\mathsf {CSG}\)) involves partitioning a set of agents into coalitions so that the social surplus (i.e. the sum of the rewards obtained by each coalition) is maximized.

Reducing coalition structures via agreement specification
Proceedings of the fourth international joint conference on Autonomous agents and multiagent systems, 2005The concept of power plays an important role in the social sciences and Castelfranchi [4] emphasizes the importance of this concept for multiagent systems. In [2] we build upon this work by distinguishing four viewpoints on multiagent systems: a mind structure, a power structure, a dependence structure and a coalition structure.

Searching for optimal coalition structures
Proceedings Fourth International Conference on MultiAgent Systems, 2002Coalition formation has been a very active area of research in multiagent systems. Most of this research has concentrated on decentralized procedures that allow self-interested agents to negotiate the formation of coalitions and division of coalition payoffs.

Conjuncturally Stable Coalition Structures
1980We consider social organizations and conflicts concerning the distribution of resources among the members of such organizations. Cooperative solutions of conflicts are defined in a manner similar to the one used in mathematical coalition games. As organizational structures manifest themselves through the coalition possibilities which they impose on the

Cooperative games with coalition structures
International Journal of Game Theory, 1974Many game-theoretic solution notions have been defined or can be defined not only with reference to the all-player coalition, but also with reference to an arbitrary coalition structure. In this paper, theorems are established that connect a given solution notion, defined for a coalition structure ℬ with the same solution notion applied to ...

Chapter 37 Coalition structures
1994Publisher Summary The study of stable coalition structures, or more generally of coalition formation, was conducted mainly within the framework of games in coalitional form. The most commonly used stability concept is the coalition-structure core, which extends individual stability to group stability.

Intermediate preferences and stable coalition structures
Journal of Mathematical Economics, 1994This paper models two forces that are at work to explain the formation of coalitions: The increasing power of the coalitions which incites to cooperate, the heterogeneity of the agents which leads to the formation of subgroups. We show that the interaction of these two forces results, under an intermediate preferences assumption, in the formation of ...

Fuzzy coalitional core for fuzzy games with coalition structures
Journal of Intelligent & Fuzzy Systems, 2014In the framework of fuzzy games with coalitional structures, the fuzzy coalitional core is proposed, which can be regarded as the generalization of the crisp coalitional core. It proves that the fuzzy coalitional core has the same polyhedrical structure as the crisp coalitional core.
