Euler path..

On the other hand, an Euler Circuit is a closed path in a graph. Like an Euler Path, it covers every edge exactly once but begins and ends at the same vertex. In this case, the initial and terminal vertex is identical. 3. Fleury’s Algorithm. Fleury’s algorithm, named after Paul-Victor Fleury, a French engineer and mathematician, is a powerful tool …So, saying that a connected graph is Eulerian is the same as saying it has vertices with all even degrees, known as the Eulerian circuit theorem. Figure 12.111 Graph of Konigsberg Bridges To understand why the Euler circuit theorem is true, think about a vertex of degree 3 on any graph, as shown in Figure 12.112 .A Hamiltonian path also visits every vertex once with no repeats, but does not have to start and end at the same vertex. Hamiltonian circuits are named for William Rowan Hamilton who studied them in the 1800’s.In this post, an algorithm to print an Eulerian trail or circuit is discussed. Following is Fleury’s Algorithm for printing the Eulerian trail or cycle. Make sure the graph has either 0 or 2 odd vertices. If there are 0 odd vertices, start anywhere.
