Hi,<br><br>I wonder whether float/double weights may cause a bug in brandes_betweenness_centrality. In the brandes_dijkstra_visitor, in the case where edge is not relaxed, there is an equality check<br><br>&nbsp; if (d_w == combine(d_v, w_e))
<br><br>in order to find if there is equally-short path from v to w. If d_w, d_v, w_e are float/doubles, isn't there gonna be a problem with the &quot;==&quot;?<br><br>Thanks<br>Ioannis<br>
