WebbThe Shapley value can be interpreted as that all agents are arranged in some order, all orderings being equally likely, and then ϕafi i is the expected marginal contribution, over all orderings, of agent i to the set of agents who precede him. Shapley value-based SCA is to assign the credit of agent i by the Shapley value ϕafi i. WebbDownloadable (with restrictions)! The Shapley value is the solution concept in cooperative game theory that is most used in both theoretical and practical settings. Unfortunately, in general, computing the Shapley value is computationally intractable. This paper focuses on computing the Shapley value of (weighted) connectivity games. For these connectivity …
