WebHere is an sample of adjacency matrix. The path is from 0 -> 8, cost is 48 and length is 3. So for example, one valid path would be: 0->3 (15), 3->6 (15 + 13), 6->8 (15 + 13 + 20 = 48). Another might be : 0->4 (20), 4->6 (20 + 8), 6 -> 8 (20 + 8 + 20 = 48). Non-valid path might include: 0->1 (8), 1->2 (8 + 4), 2->3 (8 + 4 + 3), 3->4 (8 + 4 + 3 ... WebEdge lists. One simple way to represent a graph is just a list, or array, of E ∣E ∣ edges, which we call an edge list.
