WebIn graph theory and theoretical computer science, the longest path problem is the problem of finding a simple path of maximum length in a given graph.A path is called simple if it does not have any repeated vertices; the length of a path may either be measured by its number of edges, or (in weighted graphs) by the sum of the weights of its edges.In … WebNov 5, 2024 · That is, once a path leaves some vertex, it will never return to to that vertex. There is a well-known algorithm to find a longest path in a graph, using topological sort. It is possible to find the length of a longest path using matrix multiplication in excel, but I don't see how to find the path itself, without some additional work.

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 ...
