WebThe algorithm you have suggested will indeed find the shortest path in this graph, but not all graphs in general. For example, consider this graph: Let's trace through the execution of your algorithm. First, you set d ( A) … Kruskal's algorithm finds a minimum spanning forest of an undirected edge-weighted graph. If the graph is connected, it finds a minimum spanning tree. (A minimum spanning tree of a connected graph is a subset of the edges that forms a tree that includes every vertex, where the sum of the weights of all the edges in the tree is minimized. For a disconnected graph, a minimum spanning forest is composed of a minimum spanning tree for each connected component.) It is a greedy al…
