Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking. Extra memory, usually a stack, is needed to keep track of the nodes discovered so far along a specified branch … 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. high score tech supply
