Graph theory walk vs path

WebJul 17, 2024 · Figure 6.3. 1: Euler Path Example. One Euler path for the above graph is F, A, B, C, F, E, C, D, E as shown below. Figure 6.3. 2: Euler Path. This Euler path travels every edge once and only once and starts and ends at different vertices. This graph cannot have an Euler circuit since no Euler path can start and end at the same vertex without ... 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.

An Euler path, in a graph or multigraph, is a walk through the graph which uses every edge exactly once. An Euler circuit is an Euler path which starts and stops at the same vertex. Our goal is to find a quick way to check whether a graph (or multigraph) has an Euler path or circuit.
