Worst-case bounds for subadditive geometric graphs

  • Abstract

    We consider graphs such as the minimum spanning tree, minimum Steiner tree, minimum matching, and traveling salesman tour for n points in the d-dimensional unit cube. For each of these graphs, we show that the worst-case sum of the dth powers of edge lengths is O(log n). This is a consequence of a general “gap theorem”: for any subadditive geometric graph, either the worst-case sum of edge lengths is O(nd–1)/d) and the sum of dth powers is O(log n), or the sum of edge lengths is Ω(n). We look more closely at some specific graphs: the worst-case sum of d powers is O(1) for minimum matching, but Ω(log n) for traveling salesman tour, which answers a question of Snyder and Steele.
