  • Many distances in planar graphs [Elektronski vir]
    Cabello, Sergio
    We show how to compute in ▫$O(n^{4/3} \log^{1/3} n + n^{2/3}k^{2/3} \log n)$▫ time the distance between $k$ given pairs of vertices of a planar graph $G$ with ▫$n$▫ vertices. This improves previous ... results whenever ▫$(n/\log n)^{5/6} \le k \le n^2/\log^6 n$▫. As an application, we speed up previous algorithms for computing the dilation of geometric planar graphs.
