When the system finds that the repetition rate of mathematical modeling test paper reaches more than 30%, it will prompt and suspect cheating.

The act of quoting others' achievements without indicating the source, once discovered, shall be treated as plagiarism.

Many papers with the same words, formulas or charts are copied from each other (except those with quotations).

Entries in which the program given in the appendix doesn't work and the results given in the paper can't be obtained even if the program can run will be regarded as fraud.

Modeling background

Mathematical technology

In the past half century, with the rapid development of computer technology, the application of mathematics not only plays an increasingly important role in engineering excavation technology, natural science and other fields, but also penetrates into new fields such as economy, management, finance, biology, medicine, environment, geology, population and transportation with unprecedented breadth and depth. The so-called mathematical skills have become an important part of modern high technology.

Mathematical model is a kind of simulation, which is an abstract and concise description of the essential attributes of practical topics with mathematical symbols, mathematical formulas, programs and graphics. It can not only explain some objective phenomena, but also predict the future development law, and also provide an optimal strategy or a better strategy in a sense for controlling the development of a phenomenon.

Generally speaking, mathematical model is not a direct copy of real problems, and its establishment often requires people to observe and analyze real problems in depth and carefully, and also requires people to use all kinds of mathematical knowledge flexibly and skillfully. This process of abstracting mathematical models from practical problems with applied knowledge is called mathematical modeling.
