在 Boost 实现 Bron Kerbosch 算法时保存集团

问：

我尝试使用 Boost 的 Bron-Kerbosch 算法实现将集团保存在图形中。我能够将其写入文件，但不能将其直接保存在我的代码中，以属于每个集团的节点列表向量中。任何帮助都非常感谢！

class Visitor {
public:
    template<typename Clique, typename Graph>
    void clique(const Clique& c, const Graph& g)
    {
        // Write the clique details to a file with vertices of each clique in a new line
        std::ofstream clique_file;
        clique_file.open("../output/cliques.txt", std::ios_base::app);
        for (auto it = c.begin(); it!=c.end(); ++it)
            clique_file << *it << " ";
        clique_file << std::endl;
        clique_file.close();

        // Display the cliques
        /*std::cout << "Clique: ";
        for (auto vertex : c)
            std::cout << vertex << " ";
        std::cout << std::endl;*/
    }
};

typedef boost::adjacency_list<boost::vecS, boost::vecS, boost::undirectedS> Graph;
Graph g;

boost::add_edge(1, 2, g);
boost::add_edge(2, 3, g);
boost::add_edge(3, 1, g);

std::ofstream clique_file;
clique_file.open("../output/cliques.txt", std::ios_base::trunc);
clique_file.close();

// Run Bron-Kerbosch algorithm to identify all cliques
Visitor visitor;
boost::bron_kerbosch_all_cliques(g, visitor, 1);
