AI总结:

研究连接资源分配中的福利损失,提出平等和功利连接价格概念,并为不同图结构给出连接价格的界限。

摘要:

我们研究了形成无向图的不可分割物品的分配,并探讨在要求每个代理必须接收一个连通子图时的最坏情况福利损失。我们的重点是平等福利和功利福利。具体来说,我们引入了平等(resp. 功利)连接价格的概念,该概念捕捉了在所有分配中最佳平等(resp. 功利)福利与在连通分配中最佳平等(resp. 功利)福利之间的最坏情况比率。我们为两种代理情况下的几个大类图提供了紧或渐近紧的连接价格界限,包括顶点连通性为1或2以及完全二分图的图,以及在一般情况下路径、星形和环的分配。

英文摘要:

We study the allocation of indivisible items that form an undirected graph and investigate the worst-case welfare loss when requiring that each agent must receive a connected subgraph. Our focus is on both egalitarian and utilitarian welfare. Specifically, we introduce the concept of egalitarian (resp., utilitarian) price of connectivity, which captures the worst-case ratio between the optimal egalitarian (resp., utilitarian) welfare among all allocations and that among connected allocations. We provide tight or asymptotically tight bounds on the price of connectivity for several large classes of graphs in the case of two agents -- including graphs with vertex connectivity $1$ or $2$ and complete bipartite graphs -- as well as for paths, stars, and cycles in the general case where the number of agents can be arbitrary.
