  • Shortest paths in intersection graphs of unit disks
    Cabello, Sergio ; Jejčič, Miha
    Let $G$ be a unit disk graph in the plane defined by $n$ disks whose positions are known. For the case when $G$ is unweighted, we give a simple algorithm to compute a shortest path tree from a given ... source in $O(n\log n)$ time. For the case when $G$ is weighted, we show that a shortest path tree from a given source can be computed in $O(n^{1+\varepsilon})$ time, improving the previous best time bound of $O(n^{4/3+\varepsilon})$.
