About Youth Informatics Olympic Competition
The Youth Informatics (Computer) Olympic Competition (known as the Youth Computer Programming Competition in the early days) is a subject competition aimed at popularizing computer education and computer application among young people. The national competition will be held from 1984. Since China participated in the first International Informatics Olympiad (IOI) in 1989, the national youth computer programming competition was renamed as the National Informatics Olympiad (NOI).

Contents and Evaluation Methods of Informatics Olympic Competition
Looking at the competition of adolescent informatics (computer) for more than ten years, it has gone through three stages. The first stage is 1984 ~ 1986. At that time, the BASIC language was used as the main programming language, mainly to examine students' understanding and familiarity with programming languages and programming skills. Starting from 1987, we entered the second stage and gradually increased our knowledge of data structure. Students are required not only to be familiar with programming languages, but also to learn some basic knowledge of data structures and algorithms, so as to strengthen the cultivation of computer programming and debugging ability. Since China participated in the first International Informatics Olympiad in 1989, the whole computer competition has entered the third stage, that is, students are required to learn computer theoretical knowledge and practical ability, that is, the whole informatics (computer) competition has become a competition of intelligence and computer application ability, involving computer basic knowledge, computer software knowledge, programming knowledge, combinatorial mathematics and operational research knowledge, preliminary knowledge of artificial intelligence and computer application knowledge. In recent years, Guangdong Informatics (Computer) Olympic Competition has made great progress from proposition to evaluation, and the overall requirements and practices are as close as possible to the NOI and IOI competitions.
The assessment method of Informatics Olympic Competition is closed by computer programming (continuous 3-4 hours), and there is no limitation on programming language, so the number of competition questions is usually large. After the program is completed, it must pass the strict data test, which requires students to have high programming ability: not only can they program, the programmed program can run, but also the designed program can pass the test data set in various boundary conditions and environments. This strict data testing method is undoubtedly very helpful for cultivating students' ability to analyze and solve problems.

Scientific and standardized Olympic discipline competition
The Provincial Committee of Informatics Olympics creatively formulated the competition rules, which made the competition organization more scientific and standardized. This effective regulation was formulated and implemented in 1992, and it was constantly improved in the implementation process. Thus, the whole informatics Olympic competition can be organized according to the objective laws of the competition itself, which has played a very good role in promoting the good development of the informatics Olympic competition in our province. The basic spirit of this regulation is to dynamically allocate the number of participating cities and establish a system of upgrading and demoting cities A, B and C. That is to say, the number of places for cities to participate in the final of the provincial Olympic Games each year is not fixed, nor is it allocated according to the will of the organizers, but is determined according to the competition results of the previous year (when the competition in that year is over, cities can calculate the number of places for the next year according to the results). Therefore, the increase in the number of participating places in each city is achieved by our own efforts. This has played a very good role in promoting healthy competition among cities and schools in the province and setting off a wave of learning advanced and catching up with advanced. This is an interesting adjustment with automatic adjustment function. Let's take a look at its main contents first:
Rules for the allocation of participating places
The number of participating places is divided into basic places and reward places, and the ratio of reward places to basic places is about 1:2.
(1) Basic quota: According to the results of the previous year's competition, the quota base of each city participating in the finals shall be determined respectively. There are 6 people in the top three cities (A-class cities), 4 people in the fourth to eighth cities (B-class cities), and 2 people in the remaining cities (C-class cities) 1 ~ (2 people in last year's participating cities and 0 people in last year's non-participating cities/kloc-0).
(2) Award places: for each city that won the first prize in high school or junior high school, three lesbians before the start of school, and all the contestants who won the first and second prizes in last year's competition, 1 place will be added for the city, and 1 place will be added for the two cities with the best performance in Class C.. It is also stipulated that each of the top three schools in the school group will be awarded 1 quota to the original school.
③ According to the spirit of "developing an activity to encourage girls to participate in the Informatics Olympic Games" proposed by the International Informatics Olympics in 19 1, starting from 1992, each provincial team is required to have at least 1 female students. Therefore, we also have provisions in the regulations. The basic quota for Class A and Class B cities includes 1 girl. If female students are not sent to participate, the quota will be cancelled. In order to encourage female students to participate in the competition, the regulations also stipulate that "female students must be sent to participate in the award quota, otherwise the award quota will be invalid".
(4) In order to ensure the autonomy of the teams in each city and ensure the top-notch training of successors. The regulations stipulate that "the number of places allocated to each city shall be determined by each city, but the difference shall not be greater than 1".
Establish municipal and school-level group awards
The establishment of municipal and school-level group awards has played a very important role in attracting the attention of all parties concerned and promoting healthy competition between cities and schools.
The calculation method of the total score of the city group is: teams with more than 3 participants are calculated according to the average score of the top n students (including the highest score of girls, where n is the basic quota of each city). When scoring, because the final of the provincial Olympic Games is judged by senior high school and junior high school respectively, when calculating the total score of the group, the scores of junior high school students are weighted by grade (grade one 1. 15, grade two1./kloc-0, grade three 1.05), and senior high school students are not weighted.
The calculation method of the total score of the school group is: schools with more than 2 participants are calculated according to the average score of the top 2, and the weighting method for junior high school students is the same as above.
Interestingly, this scoring method can promote the participating cities and play an automatic adjustment role of "if you don't advance, you will fall back". For example, City A entered Class A last year, and the basic quota this year is 6, while City B was Class B last year, and the basic quota this year is 4. If there are only four top players in city A, and the other two are far below the top four, there are also four top players in city B. Although the overall level is slightly lower than the top four players in city A, its final average score is likely to exceed that in city A, which is held back by the fifth and sixth players. That is to say, it is often more difficult to keep the title of A-level city than to win it, because only four top players are enough to win the title of A-level city, but it is necessary to keep the A-level. This scoring method shows that the requirements for A-level cities are higher than those for B-level cities. This kind of competition will also appear between the last 1 ~ 2 of B-class cities and the top 2 of C-class cities. In addition, we have formulated regulations that are conducive to the upgrading of C-level cities, so C-level cities can be upgraded to B-level cities within 1 ~ 2 years as long as they work hard. After several years' efforts, the scope of B-class cities can be expanded now that the number of medium-level cities in the province is less than 4-5. As the regulations have established the upgrading system for A-,B-and C-level cities, cities with good grades last year must also be prepared for danger in times of peace, and have a sense of crisis of "if they don't advance, they will fall back", while cities with poor grades last year also have the possibility of "upgrading one level with one more effort", thus increasing healthy competition among cities in the province. After several years of regulation and control, the competition between A-class and B-class cities is fierce, and they constantly change their positions, and examples of stubborn C-class cities emerge one after another.
Why doesn't this regulation allocate the number of places in each city equally? The reason lies in the unbalanced development of computer education and scientific and technological activities in cities. We recognize this imbalance, encourage the strong to be stronger, and ensure that as many promising students as possible have the opportunity to display their talents without being hindered by quota restrictions. At the same time, we also take measures to help the weak (temporarily backward cities) to ensure that our province can train a considerable number of middle school students with high computer programming level, who have achieved good results in the provincial and national informatics Olympic competitions, making our province's informatics Olympic level among the top provinces (cities) in China for many years.
