Title: On the Possibilities of DFS Tree Constructions: Sequential and Parallel Algorithms
Authors: E. Korach and Z. Ostfeld
Abstract: The Depth First Search (DFS) algorithm is one of the basic techniques which is used in a very large variety of graph algorithms. Every application of the DFS involves, beside traversing the graph, constructing a special structured tree, called a "DFS tree" that may be used subsequently. We raise two important questions regarding the structure of the DFS tree that is obtained, and discuss their solutions.
