Hi,
 
In the quick_tour example of Boost Graph Library and the documentation at this link
 
http://www.boost.org/libs/graph/doc/quick_tour.html
 
i think the edge_array for the example graph should be:
 
Edge edge_array[] = {
  Edge(A,B), Edge(A,E), Edge(A,D),Edge(A,C),
  Edge(C,A), Edge(C,D), Edge(D,B),Edge(D,A),
  Edge(E,D), Edge(E,B), Edge(E,A)};  // 11 edges
instead of the mentioned
 
Edge edge_array[] =
  { Edge(A,B), Edge(A,D), Edge(C,A), Edge(D,C),
    Edge(C,E), Edge(B,D), Edge(D,E), }; //  7 edges
