请教关于forward edge的问题

[BuShiFeiGuo]

请问在_get_forward_pure_edges 和 _get_forward_rmpath_edges时，
if min_vlb <= g.vertices[e.to].vlb
以及
if (rm_edge.to == e.to or
min_vlb > new_to_vlb or
history.has_vertex(e.to)):
continue
这里比较边的时候，为什么比较的顶点的值，而不是编号呢？不应该是比较顶点在原图中的编号来确定最右路径吗？

我也感觉这一块有点问题，自己改改了～

How did you fix it? It is problematic for me too, particularly for directed graphs. Just by changing the vertex labels for the values? Did it work for you? I would appreciate it if you share your solution. I am sorry I do not speak Chinese; Google Translate will help me in case you prefer to answer in Chinese.
