Hi, I want to use bbox as a bundled vertex property, not a bundled edge property. This is the code I was trying to compile: vector<bbox> A; adjacency_list<vecS, vecS, undirectedS, bbox> G; for (int i=0; i<A.size(), i++){ add_vertex(A[i]); } vector<bbox>::iterator pi; vector<bbox>::iterator pj; for(pi = boxVector.begin(); pi!=boxVector.end(); pi++){ for( pj = pi+1 ; pj!=boxVector.end(); pj++){ add_edge(*pi, *pj, G); }} Should'nt bbox now be accepted as a valid vertex descriptor by the add_edge function? on compiling this, I get that "no matching function for add_edge<bbox&, bbox&,adjacency_list<vecS, vecS, undirectedS, bbox> >" So, how should I implement this to get bbox as a bundled vertex property?

Hi Dave,
It is still not clear. What should my parameters be for the function add_edge() to construct the graph with bbox objects as edges?
I'm not sure how to answer you helpfully because there seem to be a few misconceptions here. To start with, the edge properties are not the edges themselves; they're just associated properties. Secondly, the graph you've declared doesn't specify any bundled edge properties; it specifies bbox as a bundled vertex property.
...but the straightforward answer to your question is that the first two parameters to add_edge should be vertex descriptors, usually as obtained from the add_vertex function.
Thanks,
