Distributing Coalition Value Calculations to Coalition Members
Within characteristic function games, agents have the option of joining one of many different coalitions, based on the utility value of each candidate coalition. However, determining this utility value can be computationally complex since the number of coalitions increases exponentially with the number of agents available. Various approaches have been proposed that mediate this problem by distr...
متن کاملPotential, coalition formation and coalition structure∗
The present paper studies a new potential function of a cooperative game with a coalition structure. When define a marginal contribution of each player, a notion of a coalition formation by Hart and Kurz (1983) is considered. Our potential is a real-valued function in contrast to Winter (1992)’s one which is vector-valued function whose dimension is the number of elements in the coalition struc...
متن کاملOn coalition formation: durable coalition structures
We define a solution to the problem of coalition formation that applies to purely hedonic games. Coalition structures satisfying our requirements are called durable, and we interpret them as much more likely to last than those coalition structures not satisfying the requirements, which we call transient. Durability results from a combination of foresight and extreme risk aversion on the part of...

When symptomatic, patients usually present with hindfoot pain and frequent sprains as children, adolescents, or young adults.

متن کاملLunotriquetral Coalition
Carpal coalition is a rare asymptomatic condition and usually detected incidentally. It may be symptomatic after a trauma and causes pain on the medial part of the wrist. Most often, lunotriquetral coalition is seen. The second frequent one is capitate-hamate coalition. It can be seen as an isolated entity or as a part of a congenital anomaly. Four radiological sub-types have been determined. I...
