There will be two competition days and one practice session, see the Schedule. On each competition day contestants will be given four tasks to solve in 5 hours. The practice session will be a 3-hour session to familiarise all contestants with the grading system and contest environment the day before the first competition.
Call for Problems
The EGOI Scientific Committee (SC) invites the competitive programming community to submit problems for EGOI 2024. We are looking for problems of varying difficulties and types (batch, output-only, or interactive). To get an idea of style and difficulty, see the problems from the previous two years, that is 2022 and 2023 (https://stats.egoi.org/tasks/). Additionally, the topics and techniques used must conform to the IOI syllabus (https://ioinformatics.org/page/syllabus/12).
Gold, silver and bronze medals are awarded to the contestants so that approximately 50 percent of all European contestants receive a medal and the ratio of gold to silver to bronze medals is approximately 1:2:3. Additionally, Honorable Mentions are awarded to contestants who placed in the top half on some contest day but did not receive any medal.
Each contestant will receive the official English version of the tasks on each contest day. For the contestant who prefer the translation of the tasks, an additional version of the tasks will be provided in their requested language.
The contestant will be provided with blank paper and writing tools during the contest. Contestants may not bring anything into the competition rooms, except for the following items under the proviso that they cannot transmit or store any data in electronic or printed format (other than the purpose for which they have been designed):
-reasonable jewellery (not watches),
-pens and pencils,
-snacks (see the details below),
-necessary medication and toiletries (with approval).
For the case of snacks, the competition site organisers shall provide all contestants with some amount of snacks. In cases when a contestant would still like to bring in snacks, the contestant should make sure that the snacks are neither noisy nor smelly, and are not disturbing for other contestants in any other way. In case of complaints from other contestants during the contest, the snack might be removed.
Any attempts to bring any other items unlisted above into the competition rooms are considered cheating. In particular, the following items are strictly prohibited in the competitions:
-any additional computing equipment (e.g., calculators, laptops, tablets),
-any books, manuals, written or printed materials,
-any data storage medium (e.g., CD-ROMs, USB drives, flash cards, micro-drives),
-any communication devices (e.g., mobile phones, radios of any sort),
-watches of any type.
The following items must be brought to (and left at) the practice session if the contestant wishes to use them during the competition days:
-keyboard (without wireless, calculation, and/or programmable functions),
-mouse (without wireless, calculation, and/or programmable functions),
-earmuffs or earplugs.
Any electronic or printed materials provided by the organisers during a competition round may be used by the contestants (e.g., a Users Guide to the Contest System or any electronic documentation or reference manuals provided in the installed contest environment or on the provided grading system).
The contestants will see their final score for each task in the contest system. However, there is a small chance that the score will change later due to appeals: submissions may be re-graded, and the final score will be that yielded by the last grading.
Each task is worth a total of 100 points if solved fully, and partial credit will be given as specified in the task statements.
Tasks might be divided into several subtasks, each worth a portion of the total points. Other tasks might use a different way of calculating the score; if so this will be specified in the task statement.
The contestant’s score on a problem is the maximum score over all their submissions on the problem. For example, say the first subtask is solved in one submission and the second subtask in another, then the contestant might not get the points for both of these subtasks. In order to receive the points for both subtasks, the contestant should submit a single solution solving both of them to the grading system.
