Cycles in an Undirected Graph

Cycles in an Undirected Graph 1. Determine if an undirected graph G = ( V , E ) is connected, where | V | = n and | E | = m . 2. Find all the cycles in an undirected graph G .

On the Diculty of Some Shortest Path Problems

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.
