合作对策解概念的逼近

Approximations of solution concepts of cooperative games

Martin Černý

摘要:

合作博弈解的计算通常依赖于所有联盟的价值。然而,在一些应用中,由于各种原因,一些联盟的值可能是未知的。我们介绍了一种方法来近似标准的解决方案的概念的基础上,只有部分信息的一个所谓的不完整的游戏。我们证明了一类极小不完全对策的思想。近似推导出不同的解决方案的概念,包括Shapley值,核仁,或核心。我们显示了一些解决方案的概念的近似显式公式,并显示了如何近似不同的基础上的额外信息的游戏。

英文摘要:

The computation of a solution concept of a cooperative game usually depends on values of all coalitions. However, in some applications, values of some of the coalitions might be unknown due to various reasons. We introduce a method to approximate standard solution concepts based only on partial information given by a so called incomplete game. We demonstrate the ideas on the class of minimal incomplete games. Approximations are derived for different solution concepts including the Shapley value, the nucleolus, or the core. We show explicit formulas for approximations of some of the solution concepts and show how the approximability differs based on additional information about the game.
