We present a new algorithm to compute motorcycle graphs. It runs in O(n √ n log n) time when n is the number of motorcycles. We give a new characterization of the straight skele...

A tree t-spanner T in a graph G is a spanning tree of G such that the distance between every pair of vertices in T is at most t times their distance in G. The tree t-spanner proble...
