Efficient polynomial time algorithms are well known for the minimum spanning tree problem. However, given an undirected graph with integer edge weights, minimum spanning trees may not be unique. In this article, we present an algorithm that lists all the minimum spanning trees included in the ...

Hence, according to the cut property, the minimum weighted edge from the cut set should be present in the minimum spanning tree of . Here, the minimum weighted edge from the cut set is . Now we’ll construct a minimum spanning tree of and check whether the edge is present or not: ...
最小生成树(Minimum Spanning Tree,MST):或者称为最小代价树Minimum-cost Spanning Tree:对无向连通图的生成树,各边的权值总和称为生成树的权,权最小的生成树称为最小生成树。 构成生成树的准则有三条: <1> 必须只使用该网络中的边来构造最小生成树。 <2> 必须使用且仅使用n-1条边来连接网络中的n个顶...
Moreover, another example is given in the case of looking for the maximum (largest) spanning tree instead of the minimum spanning tree. Furthermore, DM-MSTP is tested on eight case studies and compared to six methods developed in the literature. Graph with eight vertices Let us consider the...

1. V' = V. 2. T is connected and acyclic. Definition 2 (Minimum Spanning Tree): Consider an edge-weighted, connected, undirected graph G = (V, E). The minimum spanning tree T = (V, E') of G is the spanning tree that has the smallest total cost. The total cost of T means ...
It is shown that the minimum spanning tree problem with time windows is NP-hard. We then develop O(n2) greedy and insertion approximate algorithms for its solution. Finally, we report our computational experience with these algorithms; this experience indicates that the insertion heuristic had much...
Compute the maximum distance of the minimum spanning tree based on a distance matrixStphane Dray
Then, the problem MSTC is to find a least cost conflict free spanning tree of G. Most of the minimum spanning tree applications have a natural interpretation in the presence of conflict pairs. The MSTC also includes as a special case the well-studied Hamiltonian path problem on a directed ...
