Bi-Directional BFS

Revision en1, by inception_95, 2016-10-24 23:48:50

In what cases are Bi-Directional BFS useful? I've solved some problems but haven't found such cases where this bi-directional bfs solution is obvious! Can someone please explain how I can understand where to use bi-directional bfs or not and specially what problems it actually deals with?

Thanks_in_Advance! :)
