65438+1October12-13,2021Romanian Mathematical Olympiad was held online. Dai, a sophomore in Nanjing Foreign Languages School, won the first place in the world.
Romanian Masters of Mathematics is a mathematics competition for middle school students. It is regarded as the most difficult event in the Mathematical Olympiad for middle school students, and it is also one of the three international mathematical competitions (IMO, RMO and RMM) for middle school students in the name of China national team.
Three national team members and three national training team members participated in the 20021Romanian Masters. The first place in the world is Dai, a sophomore in Nanjing Foreign Languages School. Five years ago, Ding of Nanjing Foreign Language School took part in this competition and got the only perfect score in the world! The reporter learned that President Yan, who graduated from the middle school attached to South Normal University, won the gold medal in the Romanian Masters Cup Mathematics Competition.
In the 1 2nd Romanian Masters Cup Mathematics Competition in 2020, four players from China team won three gold medals and1bronze medals. Yan won the gold medal with a high score of 32 points, which is the best result of the team and the third in the world. Yan is also the first freshman to receive the admission notice from Tsinghua University in 2020.
Dai 20 17 graduated from Nanjing Mechanical Primary School and studied in Nanwai Middle School. He has been interested in mathematics and physics since he was a child. Dai is also a legend in the south where students are like clouds.
June 2020165438+1October Dai won the gold medal in China Mathematical Olympics (the 36th National Winter Camp for Middle School Students) and was selected for the national training team. Therefore, Dai is eligible to walk to Tsinghua Peking University in his freshman year.
Besides mathematics, Dai has also made enviable achievements in information. In the 20021National Youth Informatics Olympic Competition held in the summer vacation, Nanwai won 5 gold, 7 silver and 3 bronze, ranking first in the country! Dai and three other students were selected for the national training team.
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 1989, when China participated in the first International Informatics Olympic Competition, the whole computer competition entered the third stage, requiring students to learn computer theoretical knowledge and practical ability.
In other words, the whole information science (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.
At the same time, students are required to have strong practical ability of programming and computer debugging. 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.
