WebMay 23, 2015 · You can use Dijkstra's algorithm instead of BFS to find the shortest path on a weighted graph. Functionally, the algorithm is very similar to BFS, and can be written in a similar way to BFS. The only thing that changes is the order in which you consider the nodes. For example, in the above graph, starting at A, a BFS will process A --> B, then ... WebDepth First Search (DFS) The DFS algorithm is a recursive algorithm that uses the idea of backtracking.

Since back edges are those edges ( u, v) connecting a vertex u to an ancestor v in a depth-first tree, so no back edges means there are only tree edges, so there is no cycle. So we can simply run DFS. If find a back edge, there is a cycle. WebOct 6, 2014 · The algorithm of Depth First Search is almost similar to that of Breadth First Search.
