WebMay 20, 2024 · With a self-balancing binary search tree or binary heap, the algorithm requires Θ ( (E+V) logV) time in the worst case. where E - number of edges, V - number of vertices. I see no reason why it can't be done in O (V + E logV). In case E >= V, the complexity reduces to O (E logV) anyway. Otherwise, we have O (E) vertices connected … WebFeb 20, 2024 · As a result, DFS's temporal complexity in this scenario is O(V * V) = O. (V2). The space complexity of depth-first search algorithm. Because you are keeping track of the last visited vertex in a stack, the stack could grow to the size of the graph's vertices in the worst-case scenario. As a result, the complexity of space is O. (V).
