Fourth, the award setting
There are first prize (trophy), first prize (gold medal), second prize (silver medal) and third prize (bronze medal) in the competition, and the proportion (some of them also have progress encouragement prize) is roughly1:2: 3; The total number of winners cannot exceed 3 students of 1.

Verb (abbreviation of verb) award introduction
The International Olympic Mathematics Competition is an international youth mathematics competition, which has great influence in the world. The purpose of international Olympic competition is to discover and encourage young people with mathematical talent in the world, create conditions for scientific education exchanges among countries, and enhance the friendly relationship between teachers and students in various countries. This contest (1959) was initiated by Eastern European countries and funded by UNESCO. The first competition was hosted by Romania and held in Bucharest from July 22 to 30. 1959. Bulgaria, Czechoslovakia, Hungary, Poland, Romania and the Soviet Union participated in the competition. After that, the International Olympic Mathematics Competition was held in July every year (1980 only once), and the participating countries gradually expanded from Eastern Europe to Western Europe, Asia and America, and finally expanded from 1967 to the whole world. In 20 13, more than 80 teams participated in this competition. The United States entered the competition in 1974 and China entered the competition in 1985. After more than 40 years of development, the operation of the International Mathematical Olympiad has gradually become institutionalized and standardized, and a set of established routines has been followed by previous hosts.
The International Olympic Mathematics Competition is hosted by participating countries in turn, and the funds are provided by the host country; However, the travel expenses are borne by the participating countries. Participants must be middle school students under the age of 20, with 6 people in each team; Two other mathematicians were appointed as team leaders. The test questions were provided by the participating countries, then selected by the host country and submitted to the examiners' committee for voting, resulting in six test questions. The host country does not provide test questions. After the test questions are determined, they will be written in English, French, German, Russian and other working languages, and the team leader will translate them into the national language. The examiners' committee is composed of leaders of various countries and the chairman designated by the host country. This chairman is usually the authority on mathematics in this country.
The responsibility of intransitive verbs Committee
1. Multiple choice questions;
2. Determine the scoring standard;
3. Accurately express the problems in the working language, and translate and approve the translation into the languages of the participating countries;
4. During the competition, determine how to answer students' questions in writing;
5. Resolve the different opinions on grading between individual team leaders and coordinators;
6. Decide the number of medals and the score line.
The exam is divided into two days, 4.5 hours a day, and three questions are tested. Six players from the same team were assigned to six different examination rooms to answer questions independently. The answer sheet will be judged by the national team leader and then negotiated with the coordinator designated by the organizer. If there is any objection, it will be submitted to the examiner's Committee for arbitration. 7 points for each question, out of 42 points.
Seven, competition rules
1. The host country of IMO in the year is held by participating countries (or regions) in turn, and the required funds are borne by the host country. The whole event was hosted by the host country and presided over by the examiners' committee composed of leaders of various countries. The test questions and answers are provided by the participating countries, each country is 3? 5 questions (or not provided), the host country does not provide the test questions, but a selection committee is formed by the host country to evaluate and preliminarily select the test questions provided by various countries, mainly considering whether the test questions are duplicated with the previous test questions, and classifying the test questions according to algebra, number theory, geometry, combinatorial mathematics and combinatorial geometry. , determine the difficulty of the test questions (A, B, C), and select about 30 questions. If there are new answers to these questions, it is also required to provide answers other than the original answers and translate them into English for the examiner to choose.
2. Each team will organize a team with no more than 8 players, including no more than 6 players (students from middle schools or schools at the same level), 1 captain and vice captain. The exam will be held in two days, with 3 questions each, 4.5 hours each and 7 points each, so the highest score of each player is 42 points.
3. The official languages of the three countries. IMO is in English, French, German and Russian, and participating countries need about 26 languages. At that time, the team leaders will translate the test papers into the national language and be approved by the Coordination Committee. The marking is first judged by leaders and deputy leaders of various countries, and then negotiated with the Coordination Committee (each coordinator is responsible for marking a test question). If there are differences, the examiners' committee will arbitrate, and the negotiation will be conducted in a trusting and friendly atmosphere.
4. The number of winners is 4. IMO accounts for about half of the participants, and the winners of the first, second and third prizes are awarded according to the scores, with an average ratio of 1:2:3. In addition, the examiner's committee can award special prizes to students who have made a very beautiful (meaning simple, ingenious and original) or mathematically meaningful answer to a question.
In order to avoid the interruption of 1980 again, IMO set up a special committee (some translated as venue committee) to determine the host of each session.
According to IMO regulations, the host of each session must send an invitation to all the participating countries in the previous session, and the new participating countries must show their willingness to participate in the competition to the host, and then the host will send an invitation.
Among the countries outside Eastern Europe, Finland was the first to join (1965 7th), and France, Britain, Italy, Sweden and the Netherlands joined in succession in 1960s. 1974, the United States and Vietnam joined. Since then, the number of participating countries has increased year by year, covering Europe, the United States, Asia, Africa and Oceania, and IMO has become a truly global mathematics competition.
1988 In the 29th session, IMO set up an honorary prize for the first time at the suggestion of Hong Kong, and awarded it to those players who got full marks in at least one question although they didn't win gold, silver or bronze medals. This measure greatly mobilized the enthusiasm of all participating countries and their players.
The spirit of IMO is the Olympic spirit: what matters is not winning, but participating. ? Accordingly, since the 24th 1983, although each team (6 people) has calculated their total scores and knows how many people rank according to the order of total scores, the organizing committee does not award prizes to the team winners, because IMO is only an individual competition, not a team competition.
198 1 22nd, the United States is the host of IMO. Greitzer, chairman of the American Mathematical Olympiad Committee, sent a letter inviting China to participate, and chinese mathematical society wrote back and agreed to participate. Later, he failed to make the trip and only sent visiting scholars from the United States as observers.
1984, at the first meeting of chinese mathematical society's popularization work held in Ningbo, it was decided to send two contestants to participate in the 26th IMO in 1985, so as to learn about the situation and accumulate experience. Due to the hasty selection time, only 1 outstanding students from Beijing and Shanghai were arranged to participate. Results 1 person won the third prize, and their average score with Israel was 17, while their total score was 32. Starting from 1986, China sent six players to participate in the competition.
The brilliant achievements of China athletes have greatly stimulated the enthusiasm of millions of middle school students to learn scientific and cultural knowledge, and also greatly enhanced the sense of national honor of the people of China.
