WebPut another way -- a naive DFS blindly visits each node until it reaches the goal. Yes, it "backtracks" on leaf nodes. But a backtracker also backtracks on useless branches. One example is searching a Boggle board for words. Each tile is surrounded by 8 others, so the tree is huge, and naive DFS can take too long.
