Difference Between BFS and Dijkstra

WebFeb 20, 2024 · Depth First Search (DFS) algorithm traverses a graph in a depth-ward motion and uses a stack to remember to get the next vertex to start a search when a deadend occurs in any iteration. DFS uses LIFO (Last In First Out) principle while using Stack to find the shortest path. WebDepth First Search. Depth-first search (DFS) is an algorithm similar to BFS. It starts at some arbitrary node of the graph like BFS, but explores as far as possible along each branch. For a DFS non-recursive implementation, we are using a stack instead of a queue to store nodes which will be exploring.
