As mentioned already, the goal of this article is to take a look at two main minimum spanning tree algorithms. Both algorithms take a greedy approach to tackling the minimum spanning tree problem, but they each take do it a little differently. Prim’s Algorithm And what will will do is take List 'edgeList' one by one and try constructing the Minimum Spanning Tree. for (Edge edge : edgeList) { //Get the sets of two vertices of the edge. String root1 = kruskalMST.findSet(edge.startVertex); String root2 = kruskalMST.findSet(edge.endVertex); //check if the vertices are on the same or different set.Advantages and Disadvantages of Dijkstra's Algorithm . ... This algorithm makes a tree of the shortest path from the starting node, the source, to all other nodes (points) in the graph. ... It is different from the minimum spanning tree as the shortest distance among two vertices might not involve all the vertices of the graph....
