Graph Theory: Walk vs. Path - Mathematics Stack Exchange

WebA walk is said to be open if the first and the last vertices are different i.e. the terminal vertices are different. A walk is said to be closed if the first and last vertices are the same. That means you start walking at a vertex and end up at the same. Before proceeding further, try drawing open and closed walks to understand them better. WebNov 29, 2015 · Path.
