Sep 23, 2012 at 15:31 | comment | added | Nicholas Mancuso | Ok, under your edit yes. I wasn't sure if the OP wanted optimal-time algorithm that gives (implied optimal) solution, or just an algorithm to give the optimal solution. | |
Sep 23, 2012 at 14:06 | comment | added | JeffE | "Shortest" already means "optimal". | |

Sep 20, 2012 at 20:31 | comment | added | Nicholas Mancuso | @rizwanhudda, I should make clear that optimal in my answer, is with respect to the size/weight of the path, not in runtime. | |
Sep 20, 2012 at 19:25 | comment | added | BlueRaja - Danny Pflughoeft | You should also mention A*, which solves the same problem as Djikstra's but much faster, if you have a decent distance-heuristic available to you. | |
Sep 20, 2012 at 16:28 | comment | added | rizwanhudda | The Dijkstra's and Bellman Ford's are best known algorithms for graphs with Non-negative and negative edge weights respectively. But, has any one proved a non-trivial lower bound for these problems which matches the best known upper bound? If not, then these are not optimal. | |
