Before writing, we should sort out the main points of monographs and papers related to the topic of graduation thesis collected and read from the internet and libraries, understand the beginning, development and current research direction of the topic, and select the most representative authors from them.

When writing your graduation thesis, briefly describe the beginning, development and main direction of the research. The most important thing is to outline some current main viewpoints of the research, and indicate the representative author and the year when the opinions were published.

Furthermore, simply write a summary of the research status at home and abroad, which is divided into technical deficiency and research deficiency. That is, which aspects are not involved and whether there is a research gap; Or the research is not deep; What other theoretical or technical problems have not been solved; Or what are the shortcomings in research methods and so on. Finally, briefly introduce the development trend.

It is an important embodiment of research to pay attention to writing about the status quo of research, rather than the status quo of the subject itself. For example, the research status of writing algorithm visualization, which monographs or papers should be written, which author, what opinions, etc. Instead of a large number of algorithms to intuitively study when it came into being, what kinds of transactions it has and how it evolved, we just need to put it aside, which is also a grasp of the research.

To write the latest research results and the success of historical research, mainly write the latest results.

Don't write too little and don't write too much. Write less, indicating that there is less information to consult; If it is too much, it means that you are not generalizing, just listing it mechanically. Generally, 2-3 pages of A4 paper are enough.

If there is no literature directly related to the topic of graduation thesis, choose something similar to the topic of graduation thesis to write. Find more information from the Internet, study more and practice more.

The significance of writing about the research status at home and abroad;

Through the writing of the current research situation at home and abroad, this paper examines students' understanding and grasp of the current research scope and depth of their own topics, and indirectly examines whether students have read certain references. This is not only an indispensable part of graduation thesis writing, but also to let students know the frontier of theoretical research in related fields, so as to broaden their thinking, conduct more in-depth research on the basis of other people's achievements and avoid unnecessary duplication of work or research.
