"WebFeb 20, 2024 · DFS is better when target is far from source. Suitability for decision tree. As BFS considers all neighbor so it is not suitable for decision tree used in puzzle games. DFS is more suitable for decision tree. As with one decision, we need to traverse further to augment the decision. If we reach the conclusion, we won. Speed. BFS is slower than DFS.
