Minimum Spanning Tree Algorithms To find the minimum spanning tree of a graph, there are primarily two algorithms. Both algorithms optimally give the minimum spanning tree, but through different approaches. Kruskal’s algorithm first does the sorting of edges and then adds them based on a safe ch...

spanning tree 在min. spanning tree中,各頂點之間距離並非是shortest path Ex: 之前兩個演算法所用的例子,其中頂點對 (V2, V4) 的最短距離應為6,但所導出的兩個MST,於該頂點對的距離皆大於6!! 所有成本最小,並非其中一邊最小 國立聯合大學 資訊管理學系 演算法課程 (陳士杰) 演算法課程 (Algorithms) ...
