Dear all,

Am I right in believing that the bool returned in the function below is meant to signal to the user whether there is an edge between u and v or not?

std::pair edge(vertex_descriptor u, vertex_descriptor v, const adjacency_list& g)

The only explanation that the online documentation provides for this function is: "Returns an edge connecting vertex u to vertex v in graph g." Perhaps somebody should amend that explanation...

It says that in http://www.boost.org/doc/libs/1_42_0/libs/graph/doc/AdjacencyMatrix.html; is that missing in the adjacency_list documentation? I'll check it later and fix it if it is missing. -- Jeremiah Willcock
