Abstract(in English) | In the obnoxious facility game, we design mechanisms that output a location of an undesirable facility based on the locations of players reported by themselves. The benefit of a player is defined to be the distance between her location and the facility. A player may try to manipulate the output of the mechanism by strategically misreporting her location. We wish to design a $lambda$-group strategy-proof mechanism i.e., for every group of players, at least one player in the group cannot gain strictly more than $lambda$ times her primary benefit by having the entire group change their reports simultaneously. In this paper, we design an $k$-candidate $lambda$-group strategy-proof mechanism for the obnoxious facility game in the metric defined by $k$ half lines with a common endpoint such that each candidate is a point in each of the half-lines at the same distance to the common endpoint as other candidates. Then, we show that the benefit ratio of the mechanism is at most $1+1/(k-1)lambda$. Finally, we prove that the bound is nearly tight. |
