如您所见，查询执行了三次，平均运行时间大约是307秒，非常慢。
As you can see, the query was executed three times, and the average elapsed time is about 307 seconds, which is very slow.
平均运行时间是2.8秒，比RUNSTATS之前(大约307秒，大幅提升)。
The average elapsed time is about 2.8 seconds, a significant performance improvement compared to that before RUNSTATS (about 307 seconds).
仿真实验的结果也表明该算法在平均运行时间减少了56%的情况下多峰函数的优化效果得到了显著改善。
The simulative experimental results show that it has obvious improvement in multimodal function optimization problems with the case of the average run time reduced to 56% of the former.
