An Euler circuit is a circuit that uses every edge in a graph with no repeats. Being a circuit, it must start and end at the same vertex. The graph below has several possible Euler circuits. Here’s a couple, starting and ending at vertex A: ADEACEFCBA and AECABCFEDA. The second is shown in arrows.Euler now attempts to figure out whether there is a path that allows someone to go over each bridge once and only once. Euler follows the same steps as above, naming the five different regions with capital letters, and creates a table to check it if is possible, like the following: Number of bridges = 15, Number of bridges plus one = 16Best Answer. In an Euler circuit we go through the whole circuit without picking the pencil up. In doing so, the edges can never be repeated but vertices may repeat. In a Hamiltonian circuit the vertices and edges both can not repeat. So Avery Hamiltonain circuit is also Eulerian but it is not necessary that every euler is also Hamiltonian.The common thread in all Euler circuit problems is what we might call, the exhaustion requirement– the requirement that the route must wind its way through . . . everywhere. !
