Tarsal coalition is a condition described by partial union between tarsal bones. Its clinical significance is the potential cause for chronic pain in the ankle and foot. Diagnosis of this condition may be delayed until adolescence or early adulthood, and is often made incidentally on examination for other purposes. Treatments for this condition can range from conservative options to surgical ap...
متن کاملDistributing 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...
