WebFeb 23, 2024 · Kruskal’s Algorithm Pseudocode. Kruskal’s algorithm uses a greedy approach to build a minimum spanning tree. Let’s take a look at the pseudocode: Find the shortest connected edge and add it to the shortest edges so far as long as adding the edge doesn’t create a cycle in the graph. Repeat step 2 until all vertices have been included in ...
WebMar 15, 2024 · Prim算法的时间复杂度为O(n^2),其中n为节点数。 Kruskal算法也是一种贪心算法,它从所有边中选择权值最小的边加入生成树,直到生成树中包含所有节点为止。Kruskal算法的时间复杂度为O(mlogm),其中m为边数。 因此,Prim算法适用于稠密图,而Kruskal算法适用于稀疏图。
