The main objective of the educational process of the County Centres of Excellence is to support the development of students capable of performance and to enhance their individual capacities to the highest level. The necessity of differentiated schooling has already been successfully implemented in highly developed countries. This fact has decisively contributed to their sustainable development and economic success through their capacity of producing highly qualified and motivated human resources, with superior intellectual and moral qualities, capable of excelling and pushing the boundaries of human knowledge of scientific research.
Learning through permanent assessment, using advanced methods and technology, will lead to the formation of young people adaptable to the needs and requirements of the computer science world, which is in continuous progress.
The main purpose of this project is to offer all students equal chances at participating in a training session in order to achieve high levels of performance in the field of computer science, to stimulate their passion for the subject of informatics and also to promote the youngsters capable of such performances and schooled by the County Centres of Excellence throughout the country.
The starting point was the idea that the stimulation of competitiveness is a strong support for the act of education at its highest standards.
The objectives of the competition are the following:
Both middle school and high school students are welcome to participate in this competition. Although the competition itself is performed individually (it consists of tasks carried out individually), the registration is made within a team of maximum 8 students. All of the teams will be able to participate based on an invitation from the Prahova County Centre of Excellence. After the invitation is received, each team will nominally transmit its componence.
Each participating team will be coordinated by an informatics teacher from the same Centre. A teacher may coordinate more teams. A student may not be a member of more than one team. After the first round, only the first 8 students of each team belonging to a Romanian Centre of Excellence are permitted to take part in the second round in which the teams of the invited countries can participate.
The teams of the invited countries will consist of maximum 8 students and will also be coordinated by a specialised teacher.
The " infO(1) CUP " competition will unfold according to the following schedule:
Both of the rounds will be held following the same technical rules:
Each student will be given an account on the "infO(1)” online platform which they will personalize with personal information/a profile picture. The usernames of the accounts will be provided by the Prahova County Centre of Excellence and those will be the only ones accepted when the leaderboard is established.
In the first day of the competition, the tasks corresponding to the First infO(1) Round will be published, but only in Romanian. The students will upload the source codes corresponding to their own solutions in the announced time limit.
In the second day of the competition, the tasks corresponding to the Second infO(1) Round will be published, this time both in English and Romanian.
The registration of the teams shall be done online, on the competition portal. Each contestant will be provided with an account on the competition platform, with which it will participate in the rounds of the competition. The selection of the participating teams is the responsibility of each Centre of Excellence.
The validation of the registered teams is independent of the registration of teams, and will be done by the technical team.
The problem set of this competition will consist of 3 to 5 tasks and the amount of time students have in order to solve them will be communicated on the online platform on the day corresponding to each of the rounds.
All of the tasks in infO(1) Cup are designed to be algorithmic in nature. Efficiency plays an important role in some tasks. Whenever efficiency of an algorithm is important, test cases will be designed to differentiate between solutions with different levels of efficiency; the smallest test cases will be designed so that any reasonable correct solution for the tasks can solve them within the task constraints. Therefore, it is worthwhile to attempt a task even if the contestant does not know how to solve large test cases within the constraints.
Tasks may be of the following types:
Batch tasks : Solutions comprise a single source file of a computer program which reads data from standard input and writes its answer to standard output.
Interactive tasks : Solutions comprise a single source file of a computer program which interacts with an “opponent” program provided by the organizers. The interactive interface may be implemented either by using standard input/output, or by linking modules provided by the contestant and the organizers.
Output-only tasks: The contestants are given input files and they have to produce correct output files by any means available.
For every task other than output-only tasks, the following limits will be enforced on the contestants’ submissions:.
Time limit : A limit on the total processor time the process may consume while solving a given input.
Memory limit : A limit on the total amount of memory the process may have allocated at any moment. Note that this limit includes not only the variables, but also the executable code, global data, the stack, etc. There is no separate limit on the stack size.
Program size limit : No submitted program may exceed 100 kB in size. The size of the compiled program must not exceed 5 MB. Maximum compilation time is 10 seconds.
All task-dependent limits will be announced in the task statements.
The syllabus of the infO(1) Second Round is the same as the syllabus of the International Olympiad of Informatics.
The syllabus of the infO(1) First Round – strictly meant for the Romanian teams from the County Centres of Excellence – is the one also adopted by the national phase of the Olympiad of Informatics for the 9th-11th grades.
The accepted programming languages are C and C++.
During the rounds, students will benefit from either partial or full feedback, depending on the case.
For validation, each proposed task shall contain:
The solutions will be evaluated using the evaluation system integrated into the infO(1) platform, which is identical to the one used at the International Olympiad of Informatics. This evaluation is automatic, each candidate obtaining a score of 0 to 100 points for each task.
After the evaluation process has ended, the following will be published on the platform: the solutions of the problems, the inputs and outputs used in the evaluation and the official source codes.
The ranking will consist of the final scores obtained by the rightfully participating students in decreasing order. In case of equal scores, the difference will be made by the lexicographically decreasing order of the strings of the scores obtained at each task, in decreasing order. For instance: if a participant has obtained the scores 100, 10, 100, and another one the scores 40, 100, 70, after the sorting process these become: 100, 100, 10 and 100, 70, 40, a case in which the former contestant is placed above the latter one. If the tie remains unbroken, even after applying this criterion, the decision will be made by the board, considering the number of submissions and the moment of their upload.
The maximum number of submissions will be announced on the day of the round.
Given that the contestants are provided with real-time feedback during the rounds, and relying on the regulations adopted by the International Olympiad of Informatics, appeals are not allowed.
For each round, the leaderboard will consist of the scores obtained by the rightfully participating students, from high to low.
The contestants placed in the top of the general leaderboards will be awarded certificates and medals.
The awarding ceremony will also be held live, thus being accessible from the platform.
The regulations of the competition can be changed annually, depending on the technical modifications that may occur, at the justified proposal of the organisers.
