Re: [Boost-users] (no subject)

Hi Cedric and thank you for your reply. Actually I need the mutable graph type (using listS as vertex container) because I'll need to use the functions clear_vertex() and remove_vertex(). And I am facing the problem to create this index map property to the vertices to use the function connected_components(). I wrote a more consistent version of the code (test.cpp attached), following the instructions in a previous post by Aaron Windsor: http://boost.2283326.n4.nabble.com/connected-components-td2576097.html It compiles until I added the last line: "int num_clusters = connected_components(G, &component[0], vertex_index_map(index));" The compiler tells: gmarchand@bohr:~/TMP$ g++ test.cpp In file included from /usr/include/c++/4.4/backward/hash_set:60,                  from /usr/include/boost/graph/adjacency_list.hpp:25,                  from test.cpp:3: /usr/include/c++/4.4/backward/backward_warning.h:28:2: warning: #warning This file includes at least one deprecated or antiquated header which may be removed without further notice at a future date.

Hi, I am new to boost and I face the same problem mentioned here with "connected_components()" using a mutable graph (hence using a list for  the vertex container). I try the detailed solution of Aaron Windsor in the previous post but I still get some errors at compilation. Here is my little code:

     #include      #include

     using namespace std;      using namespace boost;

     Box& b = conf.GetBox();

You seem to use your own classes and you do not provide the definition. Thus this is unfortunately not a minimal example. So in the future, it might facilitate help from others to you, with this in the back of your head.

     if (!ai) {          ai = new AtomList();          *ai = conf.GetAtoms().AtomSelector(selecti, b);      }

     typedef boost::adjacency_list<              listS,              listS,              undirectedS,              property,              no_property>

     > graph_t;

     graph_t g(ai->size());      property_map::type index = get(vertex_index, g);

With listS as the vertex container, I would expect it to fail here. An adjacency_list with listS does not automatically create a vertex_index property. So you might give vecS a try. Especially, if you insert most of the vertices (if not all) at one specific moment and you are not constantly changing the number of vertices in the graph, I think it will make no big difference in performance whether you use vecS or listS. But you have the benefit of automatic vertex_index property-creation. I can however not compile your example (s. above) nor did you provide the error message you get, so I can't tell you for sure if this is the source of error.

graph_traits::vertex_iterator vi, vi_end;      graph_traits::vertices_size_type cnt = 0;      for(tie(vi,vi_end) = vertices(g); vi != vi_end; ++vi)          put(index, *vi, cnt++);

     for (unsigned int i = 0; i < ai->size(); ++i) {          Cartesian& crdi = ai->GetElement(i)->pos;          for (unsigned int j = i + 1; j < ai->size(); ++j) {              Cartesian& crdj = ai->GetElement(j)->pos;              double r = conf.GetBox().CartesianDistance(crdi, crdj);              if (r < rcut) {                  add_edge(vertex(i,g), vertex(j,g), g); // Add edge to Map if distance criteria is satisfied

             }          }      }

     vector<int> component(num_vertices(g));      int num_clusters = connected_components(g, &component[0], vertex_index_map(index));

The compilation is successfull until I add the last line:   int num_clusters = connected_components(g, &component[0], vertex_index_map(index));

This confuses me a bit, as I would expect the error in an earlier line. So you might look forward to provide your error message or a really working, minimal example.

Hope somebody can give a hint

Hope this helps.
