Re: [Boost-users] graph library : isomorphism.hpp vertex invariant parameter

Also, I believe the vertex_max_invariant named parameter needs to be set for
the isomorphism function to work (mine doesn't seem to work without it set).
I added the necessary change to my named_params.hpp, similar to the patches
you gave, in order to set this. It seems to work fine now.
thanks,
Patrick
