In fact, you don't need difficult mathematical tools to win the prize, just use basic mathematical tools. If you don't understand the mathematical methods in the paper, think more about why you use these methods, rather than the specific details of these methods. In fact, the key is to know what to learn, which is too easy to use.

In short, pay more attention when practicing.

1. The purpose of using mathematical tools, not specific details.

2. Typical mathematical tools for various scenes.
