The perils of transition to 64-bit time_t
(please note that there’s a correction at the bottom) In the Overview of cross-architecture portability problems, I have dedicated a section to the problems resulting from use of 32-bit time_…

工科猪咨询群友一个算法问题:
现在有一个 DAG,入度为 0 的节点称为输入,出度为 0 的节点称为输出。输入输出节点数量一致,有一个一一对应关系。
对这个 DAG 做一个“纵切”,要求满足以下条件:
1. 对应的输入和输出划分到一起(Hence “纵”)
2. 每个链保证只跨过 Cut 最多一次:也就是不允许出现以下这种链(以 A/B 表示划分到哪边):
.. -> A -> B -> ... -> B -> A -> ...
用什么算法好,或者如何 Reduce 到一个比较好的图划分问题上,然后调库侠
X 问题:Circuit as SSA,状态是输入/输出节点,做划分,不允许组合逻辑跨过 Cut 两次
