WebWatch on. We have studied two uninformed search algorithms such as Breadth-First Search (BFS) and Depth First Search (DFS) Algorithm. DFS is good because it allows a solution to be found without all competing branches having to be expanded. BFS is good because it does not get branches on dead-end paths. One way of combining the two is to … WebHere Greedy best-first search will expand : S,B,C,D,G. And BFS will only expand : S,A,B,G. Share. Cite.
