When dealing with small amounts of data, it's reasonable to try as many algorithms as possible and to pick the best one since the cost of experimentation is low.
当处理少量数据时，尝试尽可能多的算法，然后挑选最好的一个的做法是比较合理的，因为此时实验成本很低。

In the traditional course of vehicle design, modification and experimentation are repeated, so the cost of product development is high, and the cycle of vehicle development is long.
在传统的汽车设计过程中，必须经过反复修改和试验，产品开发成本高，周期较长。

Compared to flight experimentation, simulation technology has the merits of low cost and high agility.
