Dfs bfs in python
WebImplement the breadth-first search (BFS) algorithm in the breadthFirstSearch function in search.py. Again, write a graph search algorithm that avoids expanding any already visited states. Test your code the same way you did for depth-first search. python pacman.py -l mediumMaze -p SearchAgent -a fn=bfs

The algorithm begins at the root node and then it explores each branch before backtracking. It is implemented using stacks. Often while writing the code, we use recursion stacks to backtrack. By using recursion we are able to take advantage of the fact that left and right subtrees are also trees and share the same … See more This algorithm also begins at the root node and then visits all nodes level by level. That means after the root, it traverses all the direct children of the root. After all direct children of the … See more This tutorial was about BFS and DFS traversals in binary trees.
