*glancing into my crystal ball*
Are you deleting the vertices one by one? If so, don't do that. Prepare a list
containing all the vertices to be deleted and then call Graph.delete_vertices()
once. Alternatively, use Graph.induced_subgraph() to create *another* graph
which contains only the vertices you want to keep.
Best,
