Does DFS have better constants/complexity than Backtracking on a Graph?

WebMar 25, 2024 · If we observe the given graph and the traversal sequence, we can notice that for the BFS algorithm, we indeed traverse the graph breadth-wise and then go to the next level. ... In this case, the time complexity of the graph will be O (V). On the other hand, sometimes the graph may have a higher number of edges than the number of … 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.
