1. The marking process shall ensure sufficient actual marking time. The actual marking time should not be less than 2 days in principle.

2. On the premise of ensuring fairness, justice and quality of evaluation, the evaluation form can be paper version or electronic version, or a combination of both.

3. Each paper should be independently reviewed by at least 3 judges. Judges shall not read papers that do not belong to their own review at will, and shall not interfere with the review work of other judges.

4. When the judges have great differences on the evaluation results of the same paper, the evaluation group (or group) should organize reconsideration in an appropriate form to try to eliminate misjudgments and mistakes caused by different personal scoring habits.

5. The evaluation team (or group) should pay attention to the papers with outstanding innovations, but they can't reach the level of applying for national awards on the whole, and submit the report signed by the evaluation team leader to the organizing committee of the competition area for handling.

6. In the marking process, the marking group (or group) should take measures to verify and identify the papers suspected of plagiarism or plagiarism, and make records and report them to the organizing committee of the competition area.

Second, the determination of evaluation results

1. The evaluation team (or group) will submit the preliminary evaluation results to the organizing committee of the competition area, and the organizing committee of the competition area will finally determine the award-winning results (including papers submitted for review).

2. The organizing committee of the competition area shall organize an interview (defense) in the competition area before determining the final award-winning result, and the scope and method shall be decided by the organizing committee of the competition area.

3. The number of papers submitted by a competition area to the national review cannot exceed the number allocated by the National Organizing Committee to the competition area.

4. When the organizing committee of the competition area determines the national comments submitted, the number of national comments submitted by the same school cannot exceed an integer.

Relevant regulations of China Organizing Committee.

4. For the papers submitted to the national review, the organizing committee of the competition area shall number them according to the unified requirements of the national organizing committee, and input the numbering information table into the online system completely and accurately, and at the same time, print and stamp them and submit them to the national organizing committee together with the paper version.

Thirdly, the verification of paper similarity.

1. The organizing committee of the competition area should carefully organize the similarity verification of the participating papers in this competition area.

2. Papers whose similarity of related system audits exceeds a certain standard cannot be submitted to the national audit in principle.

Four, the number of papers submitted to the national competition to determine the way.

(1) First, calculate the number base of papers sent to the national review by each division. The relationship between this base and the number of teams registered in this division (hereinafter referred to as the number of teams registered) is as follows:

For the part with no more than 200 registered teams, the number of papers sent to the whole country accounts for12% of the registered teams;

For the part with more than 200 teams but no more than 500 teams, the number of papers sent for national review accounts for10% of the number of registered teams;

For the part with more than 500 teams but no more than 800 teams, the number of papers sent to the national review accounts for 8% of the number of registered teams; For the part with more than 800 registered teams, the number of papers sent to the national review accounts for 5% of the number of registered teams.

(2) The number of papers sent by each division to the national audit = the number of papers sent by this division to the national audit base * 2300/ the sum of the number of papers sent by each division to the national audit base (if the calculated number of papers sent by this division is less than 6, the number of papers sent by this division to the national audit will be treated as 6).

(3) Each paper submitted to the national review shall be clearly declared as the first prize or the second prize; The number of papers submitted to the national review in each division shall not exceed 40%.

2. The number of papers submitted by the same school in each competition area shall not exceed 4, and the number of papers submitted by the first prize shall not exceed 4.

Read 2 articles.

(4) The number of teams and papers submitted for review in each division refers to the total number of undergraduate and specialist groups.

(5) In the national evaluation of papers, the papers that declare the second prize in the competition area are not recommended to win the first prize in the country in principle (special circumstances are discussed and decided by the national evaluation expert group).

Five, about the similarity verification principle of the participating papers.

In view of the fact that the document library in Tongfang.com duplicate checking system is similar to the papers in the self-built database of the national college students' mathematical modeling competition, the principles for handling papers with high similarity are as follows:

1. In principle, any two papers with similarity greater than or equal to 25% cannot be submitted for national review; If it is to be submitted to the national review, the organizing Committee of the competition area should give an explanation when submitting it; If it is not explained, it will not be accepted during the national review.

2. The organizing committee of the competition area may, according to the similarity inspection results of the papers in the competition area, determine the specific standards for the papers that have not been submitted for national review, have not been reviewed in the competition area, and need to be dealt with in violation of discipline.

Reward suggestion

Generally speaking, there is a great chance to win the national prize through hard work. For the national competition, the method of modeling is usually the existing modeling method, because it is very difficult for you to create a brand-new model and method to solve the problem. But in order to pursue the national first prize, we must add our own ideas to the original model, which is innovative and innovative. The papers that can enter the national prize are all very good. If you want to stand out from the crowd, it is not only correct in method and clear in logic, but also outstanding, that is, well-founded, different and innovative!

The requirements for winning the prize are not that high. Generally speaking, it is good to use the existing methods to solve the problem and explain the establishment and solution of the whole model clearly and logically until the final test. There is no requirement for novelty, but the mathematical modeling competition itself has no fixed answer. As long as it is reasonable and scientific, it is possible to establish models in various ways, so as long as there is evidence to explain clearly and add your own ideas.

Have luck, strength, hard work, learn more algorithms, pay attention to scheduling, reliable teammates, hope and good mentality. Must look at the algorithm.

Be sure to look at the algorithm!

Be sure to look at the algorithm!

Bold innovation, thick-skinned, no model for national competitions!

There is no pattern at nationals!

There is no pattern at nationals!

You must have the ability to solve problems and be good at programming. There is no doubt that operational research studies hard and uses a lot of optimization to transform it into problems that operational research can solve, such as graph theory and linear programming problems. Graph theory is a hard power problem, and common algorithms need more practice.
