```cpp
if (!dfn[to]) {
Tarjan(to);
low[x] = min(low[x], low[to]);
}
else if (vis1[to] != 0) {
low[x] = min(low[x], low[to]);
}
```
改成
```cpp
if (!dfn[to]) {
Tarjan(to);
low[x] = min(low[x], low[to]);
}
else if (vis1[to] != 0) {
low[x] = min(low[x], dfn[to]);
}
```
试试

@[yangsonghan](/user/94777) 这个改不改无所谓

或者重载运算符改成
$d < A.d$
（不是很懂有没有差别）

@[FCB_Yiyang2006✈](/user/149301) 我记得0x3f3f3f3f比INT_MAX小……不知道是不是这个问题，还有您Tarjan写得好奇怪……为啥不重新建个图呢……

@[Jsxts_](/user/94777) priority_queue默认是大根堆，结构体大根堆重载需要把实际的大于重载为小于
