| Abstract: | We present a deterministic kinetic data structure for the facility location problem that maintains a subset of the moving
points as facilities such that, at any point of time, the accumulated cost for the whole point set is at most a constant factor
larger than the optimal cost. In our scenario, each point can change its status between client and facility and moves continuously
along a known trajectory in a d-dimensional Euclidean space, where d is a constant. |
