Tree-weighted neighbors and geometric k smallest spanning trees
نویسنده
چکیده
We compute the k smallest spanning trees of a point set in the planar Euclidean metric in time O(n log n log k+kmin(k, n) log(k/n)), and in the rectilinear metrics in time O(n log n + n log logn log k + kmin(k, n) log(k/n)). In three or four dimensions our time bound is O(n + kmin(k, n) log(k/n)), and in higher dimensions the bound is O(n2−2/(dd/2e+1)+2 + kn log n).

eCOMPASS – TR – 046 Rectilinear Shortest Path and Rectilinear Minimum Spanning Tree with Neighborhoods
We study the geometric shortest path and the minimum spanning tree problem with neighborhoods in the L1 metric. In this setting, we are given a graph G = (R, E), where R = {R1, . . . , Rn} is a set of polygonal regions in the plane. Placing a point pi inside each region Ri turns G into an edge-weighted graph Gp, p = {p1, . . . , pn}, where the cost of an edge is the distance between the points....
متن کاملK-Smallest Spanning Tree Segmentations
Real-world images often admit many different segmentations that have nearly the same quality according to the underlying energy function. The diversity of these solutions may be a powerful uncertainty indicator. We provide the crucial prerequisite in the context of seeded segmentation with minimum spanning trees (i.e. edge-weighted watersheds). Specifically, we show how to efficiently enumerate...
متن کاملOn Spanning 2-trees in a Graph
A k-tree is either a complete graph on k vertices or a graph T that contains a vertex whose neighbourhood in T induces a complete graph on k vertices and whose removal results in a k-tree. A subgraph of a graph is a spanning k-tree if it is a k-tree and contains every vertex of the graph. This paper is concerned with spanning 2-trees in a graph. It is shown that spanning 2-trees have close conn...
متن کاملAn Algorithm to Generate All Spanning Trees of a Graph in Order of Increasing Cost
A minimum spanning tree of an undirected graph can be easily obtained using classical algorithms by Prim or Kruskal. A number of algorithms have been proposed to enumerate all spanning trees of an undirected graph. Good time and space complexities are the major concerns of these algorithms. Most algorithms generate spanning trees using some fundamental cut or circuit. In the generation process,...
متن کاملCounting the number of spanning trees of graphs
A spanning tree of graph G is a spanning subgraph of G that is a tree. In this paper, we focus our attention on (n,m) graphs, where m = n, n + 1, n + 2, n+3 and n + 4. We also determine some coefficients of the Laplacian characteristic polynomial of fullerene graphs.
