SpletSince the graph is undirected and connected, there is at least one path between any two vertices of the graph. Therefore it is possible to find the shortest path between any two vertices using the DFS traversal algorithm. The idea is to successively seek for a smaller path from source to destination vertex using the DFS algorithm.

Each run of BFS gives you the shortest distances (and paths) from the starting vertex to every other vertex. Time complexity for one BFS is O ( V + E) = O ( V) since E = O ( V) in your sparse graph.

Splet28. okt. 2009 · The usual way to calculate a shortest path is to start like you do, but make a note whenever you encounter a new node and record the previous node on the path. …

SpletGiven a real-valued weight function , and an undirected (simple) graph , the shortest path from to is the path (where and ) that over all possible minimizes the sum When each edge in the graph has unit weight or , this is equivalent to finding the path with fewest edges. SpletA path between house ‘S’ to house ‘T’ is defined as a sequence of vertices from ‘S’ to ‘T’. Where starting house is ‘S’ and the ending house is ‘T’ and there is a road connecting two consecutive houses. Basically, the path looks like this: (S , h1 , h2 , h3 , ... T). you have to find the shortest path from ‘S’ to ...

Splet29. avg. 2024 · Given an unweighted and undirected graph, can I identify the second best shortest path from every node to every other node in polynomial time? When I say the second best, as long as one edge is different than the edges existing in the first shortest path, it is acceptable. This also implies that the length of the paths can be equal. Splet28. sep. 2024 · If there is a negative weight in the graph, then the algorithm will not work properly. Once a node has been marked as "visited", the current path to that node is marked as the shortest path to reach that node. And negative weights can alter this if the total weight can be decremented after this step has occurred. 🔹 Example of Dijkstra's Algorithm
