dfs アルゴリズムを使用してグラフの検索ツリーを作成したいと思います。コンパイル エラーが何度も発生します。コードは次のようになります (コンパイル エラーが長すぎて、貼り付けません)。

typedef adjacency_list <vecS, vecS, undirectedS> Graph;   
typedef graph_traits <Graph>::edge_descriptor Edge;
typedef graph_traits <Graph>::vertex_descriptor Vertex;

typedef pair<int, int> E;
vector<E> edges;

Graph g(edges.begin(), edges.end(), n);

vector<Vertex> p(n);
Vertex s = vertex(0,g);

breadth_first_search(g, s, visitor(record_predecessors(&p[0], on_tree_edge())));

breadth_first_searchを期待しBFSVisitorます。record_predecessorsを返しますEventVisitor。機能させるには、使用する必要がありますmake_bfs_visitor。

breadth_first_search(g, s, visitor(make_bfs_visitor(record_predecessors(&p[0], on_tree_edge()))));
