  Всем привет. Немного введения: скрипт на питоне генерирует рандомный ориентированный граф и записывает в формате graphml. Мне надо прочитать этот граф и реализовать на нём несколько алгоритмов. Алгоритм Беллмана-Форда надо применить, чтобы найти циклы с отрицательной стоимостью и поменять веса рёбер.

Код :
typedef boost::property <boost::vertex_name_t,std::string> VertexProperty;
typedef boost::property <boost::edge_weight_t,int> EdgeProperty;
typedef boost::adjacency_list<boost::vecS,boost::vecS,boost::directedS,VertexProperty,EdgeProperty> DiGraph;

int ReadFromFile(DiGraph &digraph,const std::string &path)
{
  myprint<<"<<<\n";
  int ret = 0;
  std::ifstream file_stream(path.c_str());
  if(file_stream.is_open())
  {
    myprint<<"File "<<path<<" has been opened.\n";
    boost::dynamic_properties dp; 
    dp.property("name",boost::get(boost::vertex_name,digraph));
    dp.property("weight",boost::get(boost::edge_weight,digraph));
    try
    {
      read_graphml(file_stream,digraph,dp);
    }
    catch(boost::graph_exception &ge)
    {
      myprint<<ge.what();
      ret = -1;
    }
  }
  myprint<<">>> return "<<ret<<"\n";
  return ret;
};


Граф читается и рёбрам присваиваются веса, доступ к которым можно получить вот так:
typedef typename boost::property_map<DiGraph,boost::edge_weight_t>::type WeightMap;
WeightMap weights = boost::get(boost::edge_weight,digraph);
boost::graph_traits<DiGraph>::edge_iterator edgeIt,edgeEnd;
tie(edgeIt,edgeEnd)=edges(digraph);
for(;edgeIt!=edgeEnd;edgeIt++)
  myprint<<"Edge "<<*edgeIt<<" have weight "<<weights[*edgeIt]<<"\n";


Однако метод Беллмана-Форда не компилируется. Можете помочь мне разобраться в этом?
int RemoveNegativeCostCycles(DiGraph &graph)
{
  myprint<<"<<<\n";
  boost::graph_traits<DiGraph>::vertices_size_type N = num_vertices(graph);
  bool result = boost::bellman_ford_shortest_paths(graph,N);
  myprint<<">>>"<<result<<"\n";
};
