具有外部性博弈中Shapley值计算的复杂性

Complexity of Computing the Shapley Value in Games with Externalities

Oskar Skibski

摘要:

我们研究了在具有外部性的博弈中计算Shapley值的复杂性。我们专注于两个表示的基础上的边际贡献网(嵌入MC网和加权MC网)。我们的研究结果表明,虽然加权MC网比嵌入MC网更简洁,但在计算Shapley值时,它们的计算性能略差。

英文摘要:

We study the complexity of computing the Shapley value in games with externalities. We focus on two representations based on marginal contribution nets (embedded MC-nets and weighted MC-nets). Our results show that while weighted MC-nets are more concise than embedded MC-nets, they have slightly worse computational properties when it comes to computing the Shapley value.
