Usually, the number of paper authors is 3 to 6, and there is no upper limit for signature. It is suggested that if the number of words in the paper is less than 15000, there should be no more than 5 signatures.

The format of the signature of the paper is as follows: In the revision of IEEE CSO2009 paper, the author's name and unit should be placed under the title of the paper, and displayed in the font of 12 in the center, not bold. When a paper has multiple authors, it can be displayed in two or three columns. Please refer to several sample templates for details. The author unit should be below the author, using 12 Roman characters. If possible, plus the author's email address, it is also 12 Roman characters. For more information, see Templates and Examples. Leave two blank lines in 12 dot font under the author information. For domestic authors, the author's name in the format of "first name+last name" should be used, otherwise there will be an error in retrieving the database. For example, there is a China author named Zhang San. If his signature is Zhang San, because the search organization is abroad, and foreign countries all adopt the method of putting the first name before the last name, then when searching in the database, it will be three Z, and the first name is often abbreviated to letters. So please pay attention to the author.
