NOIP What is the National Youth Informatics Olympiad test?

The main tests of the preliminary round are: basic knowledge of computer development, proficient application of computer language grammar, simple application of data structures, basic content of combinatorial mathematics, inference, analysis and other abilities.

The main tests of the semi-finals are: proficient application of language, reasonable application of data structures and algorithmic ideas, reading, analyzing, forming algorithms, realizing, debugging, and submitting problems in computer language.

For textbooks, there are many, but there is one suggestion: do not use university computer language textbooks, you can use special informatics Olympiad courses, such as "National Youth Informatics Olympiad Training Textbook (Middle School)" >>Nanjing University Press), and "National Youth Informatics Olympiad Training Textbook (Middle School Advanced Edition)" >>Nanjing University Press.

You can also go to some ** exercises to improve your level, such as etc.

This is mainly for the programming. There are three languages: C++ Pascal.

I won't talk about the preliminary round. The semi-final is to compile four questions, each with ten sets of test data, and each group has ten points.

If you don't have any program foundation, it is recommended to learn pascal; If there is a foundation, then use C

There is no specific textbook for this competition, and I recommend using the "National Youth Informatics Olympiad Training Textbook (Middle School)" >> Nanjing University Press. It's about pascal, and it's not badly written. That's what I used when I started learning.

No doubt about it!

The Informatics Olympiad is a PASCAL or C, C++ test, and some basic knowledge is a written test in the preliminary round, and the semi-final is on the computer, with 4 questions and a 100 points.

The examination form of the informatics competition is divided into two forms: written test and computer-based. Not only the informatics competition, but also the computer examination, the college student programming competition, the information technology college entrance examination and other related examination competitions are nothing more than these two forms. Informatics competitions are mainly computer-based tests, but written exams are also an important component.

The Informatics Olympiad aims to promote the popularization of computer science and focus on cultivating students' abilities, so that potential and talented students can exercise and develop their hairstyles in the competition.

National Olympiad in Informatics in Provinces (NOIP). The preliminary round is held in October each year, and the semi-final round is held in November of each year. The provincial league is divided into two levels:

Popularization group and improvement group.

The Youth Informatics (Computer) Olympiad (known as the Youth Computer Programming Contest in the early days) refers to a discipline competition that popularizes computer education and computer applications among the vast number of young people.

National competitions have been held nationwide since 1984. Since China participated in the first International Olympiad in Informatics (IOI) in 1989, the National Youth Computer Programming Competition has also been renamed the National Olympic Olympiad in Informatics (NOI).

Hello dear! We're happy to answer for you! The Informatics Olympiad tests programming ability and knowledge of algorithms.

Youth Informatics Olympiad refers to a discipline competition that popularizes computer education among young people and popularizes the application of computer computing. The National Informatics Olympiad is responsible for the task of selecting outstanding students to participate in the International Discipline Olympiad, which is approved by the State Education Commission, led by the China Association for Science and Technology, and sponsored by the China Computer Federation. In order to promote the popularization of computers and improve them, the National Informatics Olympiad has been held since 95 years.

Won the first prize in the national middle school students' Olympiad in mathematics, physics, dermal chemistry, biology and informatics in five disciplines, and won the first prize in the provincial division; Independent enrollment (college entrance examination extra points care) enjoy 5-30 points, and guaranteed university qualifications; Winners of other contests are not eligible for this treatment.

In order to promote the popularization of computers and improve them, the National Informatics Olympiad Division League was held in 95 years. Won the first prize in the national Olympiad in mathematics, physics, chemistry, biology and informatics for middle school students, and won the first prize in the provincial division; Independent enrollment (college entrance examination extra points care) enjoy 5-30 points, and guaranteed university qualifications; Winners of other contests are not eligible for this treatment.

The assessment method of the Informatics Olympiad is in the form of closed (3 to 4 hours in a row) computer-based programming and problem solving, which is not limited to programming language, and the number of competition questions is usually large.

After the program is completed, it is necessary to pass a strict data test, which has higher requirements for the students' ability to program the program: not only must they be able to program, the programmed program can run, but also the designed program must be able to pass the test data set under various boundary conditions and various environments. This rigorous data testing method is undoubtedly very helpful for cultivating students' ability to analyze and solve problems.

The entry requirements for the Informatics Olympiad are as follows:

All middle and high school players, as well as students of the same age from secondary professional schools, can sign up for the NOIP competition.

2. Players are registered with the coach's office according to the school they are enrolled in. The lecturer will summarize the school's school registration and submit it to the NOI Commissioner, who will submit it to the CCF before the registration deadline. Players who do not have an instructor in the school can contact the provincial commissioner to register, and the commissioner will register uniformly.

3. Preliminary test center requirements.

Decent style, conscientious and responsible work, strong sense of responsibility, strong discipline, dare to resist all unhealthy trends, familiar with the working procedures and requirements of the examination; Healthy; There were no immediate family members who took the exam in that year, etc.

5. During the strong preliminaries and semi-finals. NOIP, staff at each test center must wear a uniform ID. The certificate is issued by an organization in the province of NOI.

6. During the preliminaries and semi-finals. NoIP, there are storage tables set up outside each test room to facilitate the storage of belongings by contestants.

7. 7 organizational units in each province. NOI has set up a test center for the NOIP semi-finals. All test centers must be coordinated and supervised by the organizing unit, and additional testing centers should be applied to the CCF in accordance with the relevant procedures.

8. When judging the semi-final test of NOIP, the test center should turn on the signal shielding device and monitoring equipment.

National competitions have been held nationwide since 1984.

Looking at the youth informatics (computer) competition for more than ten years, it has generally gone through three stages. The first stage was from 1984 to 1986, when the basic language was used as the main programming language, which mainly assessed students' understanding and familiarity with programming language and programming skills.

Since 1987, it has entered the second stage, gradually increasing the knowledge of data structure, etc., in addition to being familiar with programming language, students are required to learn some basic knowledge of data structure and algorithm, and strengthen the cultivation of programming and debugging ability on the computer.

Quota allocation:

The number of participants is divided into basic quota and reward quota, and the ratio of reward quota to basic quota is about 1:2.

Basic quota: According to the results of the previous year's competition, the base number of places for each city to participate in the finals will be determined. 6 people from the top three cities (Class A cities), 4 people from the cities (Class B) with the fourth to eighth overall team scores, and 1 2 people from the remaining cities (Class C cities) (2 cities with participation last year and 1 city without participation last year).

Reward quota: In the previous year's competition, each high school or junior high school first prize, the top three female students, and all the participating team members won.

The first and second prize cities will each add 1 place to the city, and the 2 cities with the best results in category C will each increase 1 place. It also stipulates that the top three schools in the school group will each award 1 place to the original school.

In accordance with the spirit of the International Informatics Olympiad in '91 to "carry out an activity to encourage women to participate in the informatics competition", the national competition has stipulated that each provincial team has at least one female student to participate since '92.

Therefore, we also stipulate in the regulations that there is one female student quota in the basic quota of Class A and B cities, and if female students are not sent to participate, the quota will be cancelled. In order to encourage female students to participate in more competitions, the regulations also stipulate that "female students must be sent to participate in the award quota for female students, otherwise the reward quota will be invalid".

In order to ensure the autonomy of each city to form a team, and to ensure that the top students cultivate successors. The regulations stipulate that "the number of places allocated to each municipality shall be determined by itself, but the difference shall not be greater than one".

Participate in the NOIP of the previous year, get the first prize and then participate in the provincial selection, and participate in the NOIP (provincial league) in November of the first year, and get a high exam.

The top 4 of the provincial first prize in the first and second years of high school will enter the provincial team, and then they can participate in the NOI in August of the following year. If your province needs to save hail and rotten selection, then you have to save another one and then take the test again to enter the provincial team.

NOIP is organized by the commissioner at the same time and in different places in each province and city. Unified national syllabus and unified test papers. Students from middle, high school, or other secondary specialized schools can sign up for the league.

The league is divided into two stages: preliminary round and semi-final. The preliminary round examines general and practical computer science knowledge and is conducted in the form of a written test. The scrambling semi-final is a program design that must be debugged on a computer.
