Abstract: © Pankaj K. Agarwal, Jiangwei Pan, and Will Victor. Motivated by the increasing popularity of electric vehicles (EV) and a lack of charging stations in the road network, we study the shortest path hitting set (SPHS) problem. Roughly speaking, given an input graph G, the goal is to compute a smallsize subset H of vertices of G such that by placing charging stations at vertices in H, every shortest path in G becomes EVfeasible, i.e., an EV can travel between any two vertices of G through the shortest path with a full charge. In this paper, we propose a bicriteria approximation algorithm with running time nearlinear in the size of G that has a logarithmic approximation on H and may require the EV to slightly deviate from the shortest path. We also present a data structure for computing an EVfeasible path between two query vertices of G.
