Team spirit is the most important factor to achieve good results in mathematical modeling, and three people in a team should support each other.

Support and encourage each other. Don't mind your own part (if you are good at math, you only care about modeling, if you are good at computer, you only care about it.

Programming, well written, just writing papers), many times, a person's thinking is not comprehensive, only

It is possible to clarify the problem when we discuss it together, so no matter what section we do, three people will go to Qixin together.

It is almost impossible for a person to write a high-level article in three days.

2. Influential leaders:

In the competition, the team leader is very important, and his role is equivalent to the CPU in the computer, which is the whole team.

At the core, if the leader of a team is not effective, it will often affect the normal play of a team. Take the topic as an example.

If you want to do problem A, some people want to do problem B, but you haven't decided on the plan for a day, maybe.

There is not enough time to finish a paper, for example, when the confidence of someone in the team is shaken (especially on the third day, people may

Exhausted), leaders should play their role to rebuild the confidence of the whole team, otherwise it may lead the team to go ahead.

Give up all your efforts.

3. Reasonable time arrangement:

To do anything, a reasonable time schedule is very important, and so is modeling. You should make a plan in advance.

Planning and modeling are divided into ten sections (abstraction, problem raising, model hypothesis, problem analysis, model hypothesis,

Model establishment, model solution, result analysis, model evaluation and popularization, references, appendix). Every time you

Determine which dishes to finish in advance, so as to make yourself comfortable and ensure punctuality.

Finish the paper in time to avoid that the paper can't be finished at last because of improper time.

4. The correct paper format:

The paper is a scientific article with strict writing format, so a good paper must be

To have the correct format, take the abstract as an example. It should include six elements (problem, method, model, algorithm, conclusion and characteristics).

It is an abstract of a paper. The quality of the abstract will determine whether your paper will attract the attention of the judges, but you should listen to the marking teacher.

It is said that there are a lot of charts and programs in the abstracts of some papers this time, which do not conform to the format of the papers.

You won't get good grades in writing, so you should have a correct attitude and pay attention to the writing format.

5. Paper writing:

Personally, I think the writing of the thesis is very important. In fact, everyone's final model and results are not good.

Many, why some teams can be sent to the whole country, some teams can win provincial prizes, and some teams can get nothing.

The key lies in the writing of the paper. A good paper makes people feel logical and clear the first time they read it.

Supervision can impress the judges; Secondly, the language expression of the paper is also very important, so we should pay attention to the accuracy of words.

Sex; Besides, a good paper should have its own characteristics, viewpoints and ideas.

In short, the quality of thesis writing will directly affect the quality of grades.

6. Algorithm design: The design of the algorithm will directly affect the speed of operation. I suggest you use more math software (

Mathematice, MATLAB, maple, mathcad, lindo, lingo, SAS, etc. ), here are ten kinds of mathematics.

Common algorithms for modeling, for reference only:

1, Monte Carlo algorithm (this algorithm is also called stochastic simulation algorithm, which is solved by computer simulation.

At the same time, we can test the correctness of our model through simulation, which is necessary in the competition.

The method used)

2, data fitting, parameter estimation, interpolation and other data processing algorithms (usually you will encounter many numbers in the game.

According to the needs of processing, and the key to processing data lies in these algorithms, usually using Matlab as a tool)

3, linear programming, integer programming, multivariate programming, quadratic programming and other planning problems (modeling competitions are mostly

Number theory problems belong to optimization problems, and many times these problems can be described by mathematical programming algorithms.

Usually implemented by Lindo and Lingo software)

4, graph theory algorithm (this kind of algorithm can be divided into many kinds, including the shortest path, network flow, bipartite graph and so on.

Methods, problems involving graph theory can be solved by these methods, which need careful preparation)

5. Computer algorithms such as dynamic programming, backtracking search, divide-and-conquer algorithm and branch-and-bound algorithm (these algorithms are all calculations

The methods commonly used in method design can be used in competitions on many occasions.
