WebbIn , based on the theory of cooperative games, a Shapley value was calculated to allocate peaking compensation fees according to the marginal contribution of peaking providers. As the most common method for solving cooperative game problems, there is a “combination explosion” problem when a Shapley value is applied in large-scale systems [ 14 , 15 , 16 ].

Webb10 nov. 2015 · The former became a well-known economist, and the latter defined the concept of Nash equilibrium, the most prevalent solution concept in game theory and economic theory to date. In 2013, Shapley was awarded the Nobel Prize in economics, 8 y after Nash was awarded the prize. 1. Stochastic Games WebbViewed 7k times. 1. I understand Shapley value in game theory is a means to capture the average marginal contribution of a player. Obviously the way to do it would be to consider all possible coalitions of N players excluding a particular player, say i. So the Shapley value can be ϕ i ( N) = ∑ s ⊆ N ∖ i k ( v ( s ∪ { i }) − v ( s)).
Formally, a coalitional game is defined as: There is a set N (of n players) and a function $${\displaystyle v}$$ that maps subsets of players to the real numbers: $${\displaystyle v\colon 2^{N}\to \mathbb {R} }$$, with $${\displaystyle v(\emptyset )=0}$$, where $${\displaystyle \emptyset }$$ denotes the empty … Visa mer The Shapley value is a solution concept in cooperative game theory.
