The introduction should include the following three parts:
1. Background introduction, clearly stating your research background. It is best to give the development of this problem in the academic field in recent years. But it can't be too long and too concise. It is best to control it within one page.
2. Briefly describe the problem, because there may be a part of the problem description later.
3. Put forward the method and list the contribution points of the paper. It's important to clearly write down your innovation, highlight the difference between your own method and others, but avoid too many details.
4. Related work, this part can also be placed at the end of the paper.
5. The structure of the paper is very useful for long articles.
The description of the problem is only the description of the problem itself, not the whole paper, so I don't need to say its content.
