Sorted by: 1. Because a bridge in current graph may not be a bridge in the primary graph. Note Fleury's Algorithm deletes an edge after you pass it. Consider the following graph: You start at A A, then move to B B and delete the edge AB A B. Now BE B E becomes a bridge so the algorithm then chooses BC B C. However, BE B E is not a bridge in the ...

Since the degree of all nodes is even, there must be an edge left over which you can leave the vertex and the algorithm wouldn't have stopped. The start vertex is special because you don't need to enter it to visit it the first time (right at the start).
