In light of traditional PID controller parameters optimization with manual cut-and-try method, a novel kind of PID parameters optimization strategy based on ACA (Ant Colony Algorithm) was proposed.

针对传统的PID控制器参数多采用试验加试凑的方式由人工进行优化，提出了一种新型的基于蚁群算法的PID参数优化策略。

They cut prices drastically to try and shift stock.

他们大幅度降价，试图销出存货。

The first thing I try and get my clients to do is cut down on their hours or at least work out a flextime deal with their bosses.

Sure, I believe you should try to find ways to cut back, if possible, but I realize that not everyone shares my values and not everyone has the same life circumstances.

当然。 我是觉得你应该找到一种方式去减少污染，如果可能的话，我意识到了并不是每个人都与我有同样的观点，也并不是每个人都和我处于同样的情况。
