An analogous Eulerian trail that begins and finishes at the same vertex is known as an Eulerian circuit or cycle. An Eulerian path on a graph is a traversal of the graph that passes through each edge exactly once, and the study of these paths came up in their relation to problems studied by Euler in the 18th century like the one below: No Yes Is there a walking path that stays inside the picture and crosses each of the bridges exactly once? An Euler trail is a trail in which every pair of adjacent vertices appear consecutively. (That is, every edge is used exactly once.) An Euler tour is a closed Euler trail. Recall the historical example of the bridges of Königsberg.

The green and red path in the above image is a Hamilton Path starting from lrft-bottom or right-top. Difference Between Hamilton Circuit and Euler Circuit Indeed, for Eulerian graphs there is a simple characterization, whereas for Hamiltonian graphs one can easily show that a graph is Hamiltonian (by drawing the cycle) but there is no uniform technique to demonstrate the contrary. For larger graphs it is simply too much work to test every traversal, so we hope for clever ad hoc shortcuts.Section 5. Euler's Theorems. Recall: an Euler path or Euler circuit is a path or circuit that travels through every edge of a graph once and only once. The difference between a path and a circuit is that a circuit starts and ends at the same vertex, a path doesn't.
