Euler circuit and path examples.
If a graph has an Euler circuit, that will always be the best solution to a Chinese postman problem. Let’s determine if the multigraph of the course has an Euler circuit by looking at the degrees of the vertices in Figure 12.116. Since the degrees of the vertices are all even, and the graph is connected, the graph is Eulerian.
For example, 0, 2, 1, 0, 3, 4 is an Euler path, while 0, 2, 1, 0, 3, 4, 0 is an Euler circuit.

Graphs which have Euler paths that are not Euler Circuits must have two odd vertices. Let’s figure out if she is correct. We can think of the edges at a vertex as “entries” and “exits”. In other words, edges can be used to “enter” or “exit” a vertex. For a graph that has an Euler path, we have three type of vertices: starting ...Determine whether the given graph has an Euler circuit. Construct such a circuit when one exists. If no Euler circuit exists, determine whether the graph has an Euler path and construct such a path if one exists. a i b c d h g e f By theorem 1 there is an Euler circuit because every vertex has an even degree. The circuit is asBut, let's first see some examples where it is possible. It should be obvious that every Cycle Graph (see Cycles) admits an Euler cycle, and thus an Euler path.The stack is empty and 1 has no more neighbors. So this is the last point in this eulerian tour. Finally add 1 to the circuit. Circuit: 1, 9, 6, 1, 8, 7, 5, 8, 2, 4, 3, 2, 1 Here the order doesn't matter, but for directed graphs - it's crucial.

Using the graph shown above in Figure 6.4. 4, find the shortest route if the weights on the graph represent distance in miles. Recall the way to find out how many Hamilton circuits this complete graph has. The complete graph above has four vertices, so the number of Hamilton circuits is: (N – 1)! = (4 – 1)! = 3! = 3*2*1 = 6 Hamilton circuits.
