Cheng Peng, Houyu Zhou

AI总结:

本文针对拥挤设施选址中智能体分群且利益冲突的场景,研究了位置与群体身份误报下的策略防护机制设计,提出了最小化社会成本和最大成本的近似最优机制,并证明了其紧的性能界。

摘要:

本文研究拥挤设施选址问题的机制设计,其中智能体被划分为具有冲突利益的群体(例如,在体育馆中竞争预订篮球场),并且当设施位置更靠近其竞争者时,每个智能体的成本会增加。我们分析三种类型的误报:仅位置误报、仅群体成员身份误报以及组合误报。为了最小化社会成本,我们提出了一种在仅位置误报下实现最优性的策略防护机制。对于群体成员身份误报和组合误报,我们证明了中位数机制能够达到紧的近似界。对于最小化最大成本的目标,我们针对仅位置误报和仅群体成员身份误报引入了新颖的策略防护机制,同时在组合误报下采用最左端机制。我们证明了所有提出的机制都能实现近乎紧的性能保证。

英文摘要:

This paper investigates mechanism design for congested facility location problems, where agents are partitioned into groups with conflicting interests (e.g., competition for booking a basketball court in a gymnasium), and each agent's cost increases when the facility is located closer to their competitors. We analyze three types of misreporting: location-only, group-membership-only, and combined misreporting. To minimize social cost, we propose a strategyproof mechanism that achieves optimality under location-only misreporting. For group membership and combined misreporting, we show that the median mechanism attains tight approximation bounds. For the objective of minimizing maximum cost, we introduce novel strategyproof mechanisms for location-only and group-membership-only misreporting, while employing the leftmost mechanism under combined misreporting. We prove that all proposed mechanisms achieve nearly tight performance guarantees.
