离散树上的防策略设施定位机制

Strategyproof Facility Location Mechanisms on Discrete Trees

Alina Filimonov, Reshef Meir

摘要:

我们解决的问题,防策略(SP)设施的位置机制离散树。我们的主要结果是一个完整的表征上和SP机制。特别是,我们证明,当一个单一的代理显着影响的结果,设施的轨迹几乎包含在代理的轨迹,都沿着共同的边缘在同一方向上移动。我们展示了紧密的关系,我们的表征,以前的结果离散线和连续树。然后,我们得到进一步的影响的主要结果无限离散线。

英文摘要:

We address the problem of strategyproof (SP) facility location mechanisms on discrete trees. Our main result is a full characterization of onto and SP mechanisms. In particular, we prove that when a single agent significantly affects the outcome, the trajectory of the facility is almost contained in the trajectory of the agent, and both move in the same direction along the common edges. We show tight relations of our characterization to previous results on discrete lines and on continuous trees. We then derive further implications of the main result for infinite discrete lines.
