Dear Gabor,

Thanks a lot for your quick response and your TODO list! :) I will try the
mentioned function.
However, I have thought about the problem before I have received your
message. My plan is as follow:

1. Delete the fixed nodes and all the adjacent edges in the two graphs;
2. Check if the reduced graph2 is a subgraph of the reduced graph1.
3. If step 2 is true, then check if the edges adjacent to the fixed nodes
also exist in graph1.

Do you think the 3 steps will work? Since I met some problems with the
igraph_vector_t and igraph_vs_t objects, I have not finished coding yet (it
always says that I have invoked wrong vertex ids when I try to delete the
vertex from a graph). Sorry about the naïve errors, since I am still a
newbie about IGRAPH.

Many thanks in advance.

Best Regards
