Both of the algorithms are greedy algorithms and aim to find a subset of the edges which forms a tree that contains every vertex. However, Kruskal's algorithm chooses a node, whereas Prim's algorithm chooses an edge at each time. 5.Reference Prim's algorithm Kruskal's algorithm...
In this article, we are going to learn about the minimum spanning tree with their application and there are some algorithms for finding the minimum spanning tree which are kruskal’s algorithms and prim’s algorithm, that are also prescribed in this arti
SPFA (Shortest Path Faster Algorithm) 适用于单源、可有负权边的有向图;大多数时候当图存在负权边,Dijkstra不能使用,而Bellman-Ford时间复杂度过高,所以最好使用SPFA;其实SPFA是Bellman-Ford的优化版本,时间复杂度为O(kE),K是一个远小于V的数字,表示所有顶点进入FQ队列的平均次数(<=2),但是SPFA及...
Spanning treesA spanning tree of a graph is just a subgraph that contains all the vertices and is a tree. A graph may have many spanning trees; for instance the complete graph on four vertices has sixteen spanning treesSriram Rajan

The performance of the two algorithms could differ depending upon the certain factors such as the number of vertices. Prim’s algorithm runs in O(V2) time and works well in the massive graphs while Kruskal’s algorithm consumes O(log V) and perform suitably with small graphs. Although, among...
