This disappointing result was the starting point of a vast literature on the strategic aspects of collective decision making. Two approaches were followed to overcome

WebThe geometric median, an instrumental component of the secure machine learning toolbox, is known to be effective when robustly aggregating models (or gradients), gathered from potentially malicious (or strategic) users. What is less known is the extent to which the geometric median incentivizes dishonest behaviors.

Webanism is called strategyproof. A somewhat weaker property is incentive-compatibility (IC); in an IC mechanism truthful-ness is a Nash equilibrium: no agent can beneﬁt from being dishonest when all other agents are truthful. The Groves class of mechanisms is eﬃcient and strate-gyproof [Groves, 1973]. A Groves mechanism chooses the Webstudied strategyproof mechanisms with provable approxi-mation ratios on the line. For the obnoxious facility game, the mechanism design to improve the social utility was first studied by [2]. They presented a deterministic group strategyproof mechanism with approximation ratio 3 and a randomized strategyproof mechanism with approximation ratio 1.5.
