I have been looked the filtered_graph.

It said that "The num_vertices and num_edges functions do not filter before returning results, so they return the number of vertices or edges in the underlying graph, unfiltered".

Some times I need make new vertices from return value of num_vertices of filtered graph, not underlying graph.

How can I do?

Thank you, I will try use filtered_graph
I want to make a auto-analyze data package tool.

So, Need try to connect every byte data. It can make many new temporarily edges.

But I dont want that loss some original relationship in this graph.
Because to make new temporarily edges need original relationship.

and newer temporarily edges maybe need older temporarily edges.

And finally, I hope It can find a relationship graph of data package.

I created a graph.
And use add_edge to add some edges,

I wanna disable some edges, and add some edges. and use boost graph algorithm for enable edges

How can I do this? not create new graph.

What exactly do you want to do? There are add_edge and remove_edge functions. If you want to disable edges temporarily based on a mask, look at filtered_graph.
