Abstract: |
This paper presents a new distributed Depth-First-Search (DFS) algorithm for an asynchronous communication network, whose communication and time complexities are $O(|E|)$ and $O(|V|)$, respectively. The output of the algorithm is the DFS tree, kept in a distributed fashion. The existing algorithm, due to Cheung (1983), requires $O(|E|)$ both in communication and time complexities. |

Depth-First Search is Inherently Sequential.

Abstract: |
This paper concerns the computational complexity of depth-first search. Suppose we are given a rooted graph G with fixed adjacency lists and vertices u, v. We wish to test if u is first visited before v in depth-first search order of G. We show that this problem, for undirected and directed graphs, is complete in deterministic polynomial time with respect to deterministic log-space reductions. This gives strong evidence that depth-first search ordering can be done neither in deterministic space $(log n)^c$ nor in parallel time $(log n)^c$, for any constant $c > 0$. |
