三个Agent在一个圆上的防策略设施选址

Strategyproof Facility Location for Three Agents on a Circle

Reshef Meir

摘要:

我们考虑的设施选址问题在度量空间,专注于三个代理商的情况下。我们发现,选择每个代理的报告位置与其他两个代理之间的距离成比例的概率,结果在一个机制,是strategyproof的期望,并主导随机独裁者机制的功利社会福利。我们进一步提高了一个圆上的三个代理的上限为7/6(而随机独裁者获得4/3),并提供了第一个下界随机strategyproof设施位置在任何度量空间,使用线性规划。

英文摘要:

We consider the facility location problem in a metric space, focusing on the case of three agents. We show that selecting the reported location of each agent with probability proportional to the distance between the other two agents results in a mechanism that is strategyproof in expectation, and dominates the random dictator mechanism in terms of utilitarian social welfare. We further improve the upper bound for three agents on a circle to 7/6 (whereas random dictator obtains 4/3); and provide the first lower bounds for randomized strategyproof facility location in any metric space, using linear programming.
