Setting the "vertex_invariant" parameter to the isomorphism function
does not seem to have any affect on the behavior of the function. In
isomorphism.hpp, it appears that the function "isomorphism_impl" is
supposed to read the parameter at the return statement:
<br><br>return isomorphism(G1, G2, f,<br>choose_param(get_param(params, vertex_invariant1_t()), invariant1),<br>choose_param(get_param(params, vertex_invariant2_t()), invariant2),<br>choose_param(get_param(params, vertex_max_invariant_t()), (
invariant2.max)()),<br>index_map1, index_map2<br>);<br><br>If
&quot;vertex_invariant1_t()&quot; and &quot;vertex_invariant2_t()&quot; are both changed to
&quot;vertex_invariant_t()&quot;, the setting of the parameter then seems to have
an affect. Has anyone been able to successfully set the
vertex_invariant parameter using the named parameter version of the
isomorphism function? I have had to resort to calling one of the
internal isomorphism functions to set this parameter.
<br><br>any help is appreciated,<br><span>Patrick</span>
