How to use boost::graph algorithms with listS, set

2019-02-25 10:07发布

The boost examples for usage of the boost::graph library usually employ a graph like

using namespace boost;
typedef adjacency_list
    < vecS, // edge container 
      vecS, // vertex container
      undirectedS,
      property<vertex_index_t, int>,
      property<edge_index_t, int>
    > graph;

and therefore they work very well. But I have a graph with

typedef adjacency_list
   < setS, // edge container 
     listS, // vertex container
     undirectedS,
     boost::no_property,  // vertex property
     boost::no_property // edge property
   > graph;

and the algorithms don't work out of the box. In most cases a map for looking up a vertex_descriptor for a particular vertex index (integer value) has to be provided.

I want to check whether my graph is planar and compute a planar embedding of it. I provide a vertex index map and it does work in that way for e.g. the connected_components algorithm, but obviously not for the boyer_myrvold_planarity_test:

using namespace boost;

typedef adjacency_list
<boost::setS, boost::listS, undirectedS,
     boost::no_property, boost::no_property> graph;

typedef  boost::graph_traits<graph>::edge_descriptor    EdgeDesc;
typedef boost::graph_traits<graph>::vertex_descriptor   VertexDesc;

typedef std::map<VertexDesc, size_t> VertexDescMap;
typedef std::map<EdgeDesc, size_t> EdgeDescMap;
typedef boost::graph_traits<graph>::vertex_iterator VertexIterator;


graph K_4;

std::vector<VertexDesc> vertex;
for(int i=0;i < 4; ++i){
    VertexDesc v = boost::add_vertex(K_4);
    vertex.push_back(v);
}


  add_edge(vertex[0], vertex[1], K_4);
  add_edge(vertex[0], vertex[2], K_4);
  add_edge(vertex[0], vertex[3], K_4);
  add_edge(vertex[1], vertex[2], K_4);
  add_edge(vertex[1], vertex[3], K_4);
  add_edge(vertex[2], vertex[3], K_4);



   VertexDescMap vidxMap;
   boost::associative_property_map<VertexDescMap> vindexMap(vidxMap);
   VertexIterator di, dj;
   boost::tie(di, dj) = boost::vertices(K_4);
   for(int i = 0; di != dj; ++di,++i){
      boost::put(vindexMap, (*di), i);
   }


   if (boyer_myrvold_planarity_test(
   boost::boyer_myrvold_params::graph = K_4, 
   boost::boyer_myrvold_params::vertex_index_map = vindexMap))
    std::cout << "K_4 is planar." << std::endl;
  else
    std::cout << "ERROR! K_4 should have been recognized as planar!" 
          << std::endl;

It results in various cryptic template errors...

In brief, it complains that it cannot convert/use it as I would like it.

How can I make it work?

What else do I have to give to the function?

Unfortunately, there are hardly boost examples for working with setS or listS as containers. Furthermore, I cannot use the property tags because this is part of a larger implementation and I need to keep the properties external.

I would be very happy if somebody has a suggestion.

The error message tells that you need to provide a vertex_index map; see the same problem answered here. Various ways to add the vertex_index map to adjacency_list are discussed here; in fact their problem is almost identical to yours.
