### What is the difference between mathematical modeling USAB discrete and continuous questions

Continuous and discrete question types in mathematical modeling generally refer to the AB questions in the USAB.

Continuous: the variable factors in the problem are continuously changing, for example, the bathtub temperature in this year’s USAB question A varies continuously over time

Discrete: the variable factors in the problem are discretely varying, for example, the treatment of space debris in this year’s USAB question B. The treatment of each piece of debris is discrete

Continuous and discrete refer to the variables in the problem itself, which have a have little effect, and are mainly used to differentiate between question types.

### How to take the title of an American contest essay

The following are the considerations for giving a title to an essay:

The essay can directly convey to the reader the message of what the essay is doing, and words like Studieson, which have practically no valid message, should be avoided as much as possible; the title of the essay should be as specific and clear as possible, and can reflect the main contribution of the essay; the title of the essay shouldn’t be too broad; don’t make grammatical errors ah.

(In a 2010 paper on finding the best spot to hit a ball, there was a paper called “ScienceinSweetSpot”, which made three major mistakes in its title: no article before “Science” about a specific study, an incorrect preposition, and no article before a singular countable noun. The correct title would have been “ThescienceoftheSweetSpot”.)

For example, the title of an O Award paper from ’16 is good: StrategiestoEliminatingSpaceDebris:ApproachesfromaTimeDependentEvaluationModel.

It’s well known that. The title is the eyes of the paper, a good title will give people a bright feeling, through the title editors and experts will have a preliminary impression of the paper, this impression will also affect the teacher or journal editors on the overall evaluation of your paper. Therefore, the importance of the title in the paper, take a good, appropriate title is so important. A good title should balance professionalism and readability.

### How many trivia questions are there in the US tournament

6 trivia questions.

Every year, the U.S. tournament will give six questions, A, B, C, D, E, F. A, B, C are MCM questions; D, E, F are ICM questions, and the participating teams can choose any one of them to answer, and in the final judging, the MCM questions and the ICM questions are judged separately.

### How many prizes correspond to the levels of the U.S. competition

The U.S. Mathematical Modeling Competition for Undergraduates (MCM/ICM) is generally divided into four levels: Excellence, Honorable Mention, Successful Participation, and Not Awarded.

The U.S. Mathematical Modeling Competition for Undergraduates (MCM/ICM) divides teams into grades based on their performance and awards prizes at different levels. Here, we focus on the award levels corresponding to the MCM competition levels.

First Prize: if the team’s paper score is more than 96 points, it can get the first prize. Second Prize: if the team’s paper score is between 90 and 96, it can win the second prize. Third Prize: If the team’s paper score is between 80 and 90, the team will be awarded the third prize. Excellence Award: If the team’s paper score is between 70 and 80 points, then it can get the Excellence Award.

Honorable Mentions: Honorable Mentions will be awarded if the team’s paper scores between 60 and 70, or if the team’s paper does not receive a separate award, but the results have been published in a conference proceedings. Successful Participation Award: If a team submits a paper and does not receive an award, it will receive a Successful Participation Award.

It is important to note that the above awards apply only to the MCM competition, while the award names and scoring criteria will be different in the ICM competition. Overall, winning the first, second and third prizes can be considered a more desirable outcome, while gaining experience through participation and earning an honorable mention or successful participation award can also help to improve one’s skills and knowledge.

Expanded information:

The American Collegiate Mathematics Contest is an international competition at the undergraduate level, with topics such as TheMathematicalContestinModeling (MCM) and TheInterdisciplinaryContestinModeling. TheInterdisciplinaryContestinModeling (ICM).

TheMathematicalContestinModeling (MCM), commonly known as the Mathematical Modeling Competition, has three problems: problemA, problemB, and problemC. problemA is a continuous problem, problemB is a discrete problem, and problemC is a data-processing problem, which mostly gives a large amount of tabular data for The questions are mostly about data processing, and most of them give a lot of tabular data for data processing.
