We provide mechanisms and new metric distortion bounds for line-up elections. In such elections, a set of n voters, k candidates, and ell positions are all located in a metric space. The goal is to choose a set of candidates and assign them to different positions, so as to minimize the total cost of…
We consider a social choice setting in which agents and alternatives are represented by points in a metric space, and the cost of an agent for an alternative is the distance between the corresponding points in the space. The goal is to choose a single alternative to (approximately) minimize the soci…
We study the classic facility location setting, where we are given n clients and m possible facility locations in some arbitrary metric space, and want to choose a location to build a facility. The exact same setting also arises in spatial social choice, where voters are the clients and the goal is…
