8 6a-Graphs-More applications of DFS Connected components of an **undirected** graph. Each call to DFS_VISIT (from DFS) explores an entire connected component (see ex. 22.3-11).

9 Some graph-processing problems Path. Is there a path between s to t? Shortest path. What is the shortest path between s and t? Longest path. What is the longest simple path between s and t?

Fast Approximation Algorithms for Cut-based Problems in **Undirected** Graphs Aleksander Mądry ⁄ Massachusetts Institute of Technology madry@mit.edu Abstract We present a general method of designing fast approximation algorithms for cut-based min

To put our lower bound in perspective, we note that both these problems (replacement paths and second shortest path) can be solved in near linear time for **undirected** graphs.
