Spend time thinking about what users might do on your site and model worst case scenarios to inject into the testing process.

请多花些时间考虑用户可能在您的站点中进行哪些操作，并对最糟糕的用例场景进行模拟，以注入到测试过程中。

For no-waited model, we show it is strongly NP-hard, and present a pseudo-polynomial time optimal algorithm and an approximation algorithm with worst-case ratio 5/3.

对于不可等待的情况证明了它是强NP-难的，并给出了动态规划算法和一个最坏情况界为5/3的近似算法。
