Eric, no I did not forget to add vertices in my graph. It is build in another function that I removed for clarity. I have 333 vertices in my graph, and 4 edges. Do I correctly use the edge_reverse property_map?<br>


</div></div></blockquote></div><div><br>Can you pin down a line number?<br></div></div></blockquote><div><br>Sorry for my previous message. Enabling debug flags, I had a better idea of the problem:<br><br>/usr/include/boost/graph/kolmogorov_max_flow.hpp:115: [...] Assertion `m_rev_edge_map[m_rev_edge_map[*ei]] == *ei&#39; failed.<br>

<br>So, I add in my code:<br><br>    rev[p_reverse.first] = p.first;<br>    // ...<br>    rev[p2_reverse.first] = p2.first;<br><br>It seems now to work correctly.<br>Thanks for your help.<br><br>Regards,<br><br>Olivier<br>
