Electronic paper format specification

1. Each participating team should name and submit the following two electronic documents according to the requirements of the National Mathematical Modeling Competition for College Students, corresponding to the participating papers and related certification materials respectively.

2. The electronic version of the paper can't contain the commitment letter and the numbered page (that is, the first page of the electronic version of the paper is the abstract page). In addition, its content and format must be completely consistent with the paper version (including text and appendix), and it must be a separate document.
