Hi, thanks for the fast reply.
I will try that solution..
Where can I find the 0.6 version? Or is it the next major update?

Hi Benjamin,
http://en.wikipedia.org/wiki/Maximum_common_subgraph_isomorphism_problem says that a possible way to find the maximum common subgraph is to create the modular product of the two graphs, which does not seem to be very difficult, and the then find the maximum clique in this graph, for which igraph has algorithms. (The implementation in the 0.6 version is much faster.)
Even if your graphs have only 200 vertices, this might be a difficult thing to calculate, because already the modular product will have about 200x200 vertices, and you need to find the largest clique in these, which is an NP-complete problem (of course).
I am not sure what you mean about "most accurate", you are interested in approximate solutions?
