1. Participation in Náboj Online
Náboj Online is a competition designed primarily for teams consisting of high-school students. Any team must consist of at most five members. There are three categories: Junior, Senior and Open. Teams competing in the Junior category may consist only of high-school students, who do not yet attend their final year of high-school. Teams competing in the Senior category may consist of any high-school students and, moreover, those who were studying at high school during the summer term of 2019/2020; these can also take part in Senior category. All members of the team must be from the same school. Those who fall under the exception above are for these purposes considered as students of the school they attended during the summer term of 2019/2020. Teams competing in the Open category are not restricted by age, school or student status.
Schools or teams can enrol for participation on the competition website until the registration end date or reaching the full capacity, whichever comes first. All necessary information on the dates, numbers of registered teams and overall competitor capacity is available on the respective website. The registration takes place in two rounds: During the first round, each school may enrol any number of teams, but only the first two teams in each category are accepted into the competition (unless full capacity has been reached), all further teams are put on the waiting list. During the second round, which starts two weeks before the competition, also the third and the fourth enrolled teams for each school in each category are accepted (unless full capacity has been reached). The registration ends three days before the competition. If, at that time, full capacity has still not been reached and the waiting list for given competition site is not empty, all remaining teams are accepted so that the fourth enrolled team for each school is accepted, then the fifth one, the sixth one etc., until full capacity is reached or waiting list is empty. Registration for the Open category will start during the second round and the capacity of this category will depend on the number of registered teams in Junior and Senior categories.
3. The Competition Start
The contestants can participate from anywhere, the only necessary condition is a stable internet connection. The organizers will not be held liable for any damage caused by a poor internet connection on the side of contestants. The members of the team do not have to be together in person during the competition, however, it is recommended for easier communication if they have the option. We ask all contestants to adhere to all health measures effective in their location during the competition. Each registered team will receive two emails: a week and a day before the competition, respectively. This email will contain login information necessary to enter the competition interface where the team will be able to access the problems and submit their solutions.
4. Solving and submitting the Problems
The Contestants work on any of the six problems they have; the solution is either a single number or multiple numbers. As soon as the team concludes that their result to a problem is correct, they submit it through the competition interface. If the solution is correct, they will be notified and a new problem will unlock. The number of submissions to a given problem is unlimited, however, after submitting n incorrect answers the team will have to wait n minutes for a new submission of that problem, e.g. one minute after the first incorrect submission, two minutes after the second incorrect submission, three minutes after the third one etc. In the last 5 minutes of the competition, it is possible to submit answers every 10 seconds, overriding the rule above.
5. The End of the Competition
The competition lasts two hours. After that time has passed, it will no longer be possible to submit any solutions in the competition interface. Immediately after the competition ends and before the results announcement, it will be possible to send any potential complaints to firstname.lastname@example.org.
6. The Winner
In every category wins the local team that solved the highest number of problems. Should several teams solve the same number of problems, the winner is determined on the basis of the highest ordinal number of problems solved. If two or more teams have the number equal, the second highest ordinal number of the problems solved determines the winner etc. In case of teams having the same set of problems solved, the winning order is determined depending on the time of submitting the solutions. If this time is equal, the order is determined depending on the time of submitting the last but one problem etc. The same method is applied to determine the order of the rest of the teams. The same principles are used when determining the national and international results.
7. Permitted Tools
Unlike in the regular competition, it is permitted to use any tools available. However, it is not allowed to receive help from people not participating in the competition. Furthermore, any communication or cooperation between different teams during the competition is strictly forbidden.
