If the cost estimatd does not correctly describe the real cost during SQL execution, the access plan picked by the optimizer may not be optimal.
如果评估得到的开销不能够正确反映SQL执行中的实际开销，那么优化器所选择的存取计划可能不是最优的。
So if every unemployed person grabbed the first job that came his way, the match between workers and jobs that resulted would not be optimal.

If the remote plan does not appear optimal, the system administrator for the remote data source should be contacted to investigate the performance issue.
如果远程计划不是最优的，那么应该与远程数据源的系统管理员联系，以便调查性能问题。
In this case, the optimizer creates a different access plan, which may not be optimal if the user input is 0.
在这种情况下，优化器会创建的存取计划都是不一样的，这在用户输入为0时可能不是最优的。

And the result shows that this optimal strategy can improve query performance saliently if the query constraint expression is not a CNF.
结果表明，当查询条件不是合取范式时，该优化策略明显提高了查询性能。
Focuses on practical algorithms even if they are not asymptotically optimal.
集中于实际的算法，即使他们不渐近最佳。
General, if we do not consider the length of pattern, a time complexity o (n) algorithm should be optimal, but the fact is not the case.
一般，如果不考虑模式串的长度，一个具有时间复杂度o (n)的算法应该是最优的了，但是事实不是如此。
