WebFeb 20, 2024 · Both BFS and DFS are types of graph traversal algorithms, but they are different from each other. BFS or Breadth First Search starts from the top node in the graph and travels down until it reaches the root node. On the other hand, DFS or Depth First Search starts from the top node and follows a path to reaches the end node of the path. WebAug 3, 2024 · Breadth-First Search and Depth-First Search are two techniques of traversing graphs and trees. In this tutorial, we will focus mainly on BFS and DFS traversals in trees.

"WebJul 18, 2024 · One route from node A to node B might be three steps 1+1+1 and another might be one step of 2. There might be a time problem exploring every route, but you would abandon a route once it becomes more expensive (or eventually cannot be less) than the best one so far. Also caching can dramatically reduce the search space. " - Dfs in a graph
