Weighted graph is a graph that has all edges with weight values. Prim's is a greedy algorithm and At every step, it considers all the edges that connect the two sets, and picks the minimum weight edge from these edges. One set holds the nodes that are already selected, and another set holds the item those are not considered yet. So the two disjoint subsets (discussed above) of vertices must be connected to make a Spanning Tree. In each of n iterations, we will scan through all the m edges and test whether the current edge joins a tree with a non-tree vertex and whether this is the smallest edge seen thus far. Sort all the edges in non-decreasing order of their weight. Dijkstra’s algorithm is very similar to Prim’s algorithm for minimum spanning tree.Like Prim’s MST, we generate a SPT (shortest path tree) with given source as root.
