例如，使用gencon策略执行GC花费的时间通常比使用optthruput策略花费的时间更多(参见参考资料)。

For example, the time spent doing GC with the gencon policy is generally higher than the time spent collecting with the optthruput policy (see Resources).

已有的极点配置算法对离散时间系统在保证闭环系统的稳定性方面是有效的，但由于算法采用的不是优化策略，因而对任意的有界参考输出不具有最优跟踪性能。

There are lots of pole configuration algorithms which can guarantee the stability of closed loop system, but the algorithm have not optimal trace for lack of optimal strategy.
