Consider a finite set of targets, with each target assigned a
relative deadline, and each pair of targets assigned a
transit flight time. Given a flock of identical UAVs, can one
ensure that every target is repeatedly visited by some UAV at
intervals of duration at most the target's relative deadline? The
Cyclic-Routing UAV Problem (CR-UAV) is the question of whether this task has a
solution.
This problem can straightforwardly be solved in PSPACE by
modelling it as a network of timed automata. The special case of there
being a single UAV is claimed to be NP-complete in the literature. In
this paper, we show that the CR-UAV Problem is in fact PSPACE-complete
even in the single-UAV case.
