[Boost-users] fixing graph labels

Hello, Have created a graph using erdos_renyi_generator and the vertices are labelled 1 to n. When I remove a vertex the labels are then 1 to n-1. Is there any way to stop this relabelling from happening? Heres some info: typedef adjacency_list Graph; typedef erdos_renyi_iterator ERGen; Graph g(ERGen(gen, n, p), ERGen(), n); Cheers, Harry
