Explanation Algorithm Used: Fleury’s Algorithm: To determine an Euler path or an Euler circuit: “A. Use Euler’s theorem to determine whether an Euler path or an Euler circuit exists. If one exists proceed with steps 2-5. B. If the graph has no odd vertices (therefore has at least one Euler circuit, which is also an Euler circuit), choose any vertex as the starting point. If the graph has exactly two odd vertices (therefore, has only an Euler path), choose one of the two odd vertices as the starting point. C. Being to trace edges as you move through the graph. Number the edges as you trace them. Since you can’t trace any edges twice in Euler paths and Euler circuits, once an edge is traced consider it “invisible”. D. When faced with a choice of edges to trace, if possible, choose an edge that is not a bridge (that is, don’t create a disconnected graph with your choice of edges). E. Continue until each edges of the entire graph has been traced once”. The given graph is shown below in Figure 1. From Figure 1, it is observed that the vertices F and H are odd vertices and these are the only odd vertices in the given graph. That is, this graph has exactly two odd vertices. Then by the Euler theorem part (b), this graph has at least one Euler path but no Euler circuits. To find the Euler path by the Fleury’s Algorithm, starts with either at F or at H (since, they are the odd vertices) and ends with the other vertex. First start with the vertex F , at vertex F there are three choices for edges: edge FE , FC , and FI , none of them is a bridge, so choose any edges from FE , FC , and FI . First choose the edge FC , then edge is changed as dashed line and named it as 1. Now the position is at the vertex C , there is only one choice for edge is edge CB . So choose the edge CB and name it as 2. Next the positions is at the vertex B, there are three choices for edges BA , BD , and BE , none of them is a bridge, so choose any edges from BA , BD , and BE ...
