Complexity of Depth First Search The time complexity of the DFS algorithm is represented in the form ofO(V + E), whereVis the number of nodes andEis the number of edges. The space complexity of the algorithm isO(V). Application of DFS Algorithm ...

DFS (Depth First Search) is an algorithm used to traverse graph or tree. We first select the root node of a tree, or any random node(in case of graph) and explore as far as possible in a branch and then come back to a fixed point. DFS is generally used for connectivity questions. ...

We present an algorithm for a fault tolerant Depth First Search (DFS) Tree in an undirected graph. This algorithm is drastically simpler than the current state-of-the-art algorithms for this problem, uses optimal space and optimal preprocessing time, and still achieves better time complexity. ...
