Minimum weighted spanning tree
WebAbstract: Given a connected, weighted, undirected graph G=(V, E) and a bound D, bounded diameter minimum spanning tree problem (BDMST) seeks spanning tree on G with smallest weight in which no path between two vertices contains more than D edges. This problem is NP-hard for 4 les D les V - 1. This paper proposes three new multi … WebTo calculate the minimum spanning tree on an unweighted graph, we can use the breadth-first search algorithm. Breadth-first search starts at a source node and traverses the …

WebIn the following, undirected graph, circles represent vertices and numbers represent edge weights. The red edges are part of a minimum spanning trees for this graph. What is the most accurate range for the edge weight x? x <= 7 x <= 8 x > 3 7 <= x <= 8? WebGiven a graph G ( V, A), we know that any spanning tree contains an edge in every cutset. Let S m i n m a x and S be the minimax weight spanning tree of G and minimum weight spanning tree of G resp. Any edge e ∈ S is associated with a cutset C. Corresponding to cutset C, S m i n m a x must also contain an edge, say e ′.
