WebJan 13, 2024 · Step 2. We can observe that weight of 0 – 1 is “4” while 0 – 7 is “8”. We have selected the lowest weight edge, which is 0 – 4. Since we already found the adjacent node of “0”, now we have to find all the … WebKruskal’s Algorithm. Kruskal’s Algorithm builds the spanning tree by adding edges one by one into a growing spanning tree. Kruskal's algorithm follows greedy approach as in each iteration it finds an edge which has least weight and add it to the growing spanning tree. Algorithm Steps: Sort the graph edges with respect to their weights.
