These algorithms are used to search the tree and find the shortest path from starting node to goal node in the tree.

WebAs the name BFS suggests, you are required to traverse the graph breadthwise as follows: First move horizontally and visit all the nodes of the current layer. Move to the next layer. Consider the following diagram. … WebDepth-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 …
