• The planned schedule for two days (task selection+translation, 3 tasks for each day) All times in Georgian time (Tbilisi) (GMT+4)
    • 1. 8:00 am: Send the task statements to team leaders (DOC files via email)
    • 2. 8:00 am – 9:00 am: Leaders read the task statements and report major issues to SC
    • 3. 9:00 am: For tasks with no major objections, team leaders and/or (additional) translators can start to translate
    • 4. 9:30 am – 10:00 am: SC addresses the major objections or errors and makes the final task statements. SC will explain their decision. If SC cannot solve the issues, SC can switch to backup tasks (then, another round of major objections will be conducted).
    • 5. 10:00 am: Team leaders and/or (additional) translators can translate the remaining task statements
    • 6. 12:00 – 12:30 pm- Send the translated task statements to SC (PDF files via email)
    • 7. 12:00 pm – 12:45 pm: Time window for the HTC to send translated tasks via email
    • 8. 12:45 pm: Contestants are to be seated in front of their computer. Team leaders/local proctors to notify the host organizing team if their contestants have issues
    • 9. 1:00 pm: The start of contest (If there is any delay of the translation process, SC can delay the start of contest!)

Key differences

  • 1. There is no physical meeting or E-meeting. All announcements are made by email
  • 2. There is no voting. SC makes the final decision. But SC needs to explain their decision to the team leaders by email
  • 3. Unlike onsite EJOI, each team is allowed to have one additional officially registered translator. This can speed up the translation process as time is limited.


  • 1. If you are not sure of anything in the rules, please contact IC
  • 2. No physical or online meeting for translation
  • 3. No vote for individual tasks, no minor objections. The SC/HSC will try our best to minimize the length of task statements and avoid debatable wordings
  • 4. Team leaders send major objections or errors to SC by email
  • 5. Translations must be submitted to the host committee via email as PDF files. No additional translation software will be provided
  • 6. There is no vote for accepting all tasks. SC makes the final decision
  • 7. Task solutions will not be released
  • 8. If team leaders and translator print anything or make any electronic copies, they should destroy them at the end of the translation period
  • 9. The team leaders and translator cannot communicate with students during the translation period, before the start of the contest and during the contest. Proctors should have no conflict of interest with students.
  • 10. During the contest, students can view all translated task statements provided by all team leaders (this is to help students to understand the task statement)
  • 11. All teams should translate directly from the English version. They should not rely on other versions to translate since they have only 4 hours
  • 12. Team leaders are responsible to secure enough manpower for translation, proctoring and other related activities.


  • 1. During registration, each team needs to provide the following information:
    ● The data of additional translator (registered as Adjunct)
    ● An email to make announcements to the team leaders
    ● Do they want to translate? What language(s) do they use?
    ● Ask the role of each member (proctor or translator or both)
  • 2. To speed up the uploading of tasks to the CMS server, ITC can start uploading once any individual task is finalized. If Team leaders/translators are submitting more than one version of a translated task statement they have to indicate the version number like rabbits_v5.pdf where rabbits is the name of the task. ITC will upload only the latest version to the CMS.


  • Due to COVID-19, EJOI’2020, organized by Georgia, will be conducted as an online competition. To ensure the integrity of the competition results, the Host organizing committee hopes that every team could assist in enforcing the rules of the competition in the best possible way. By default, team leaders are assumed to enforce these minimal rules for their team during the execution of EJOI’2020 Georgia (Online Competition). Deviation from the requirements (unless permitted by the IC) will be ground for immediate disqualification.

Brief Description of the Contest Rules

  • ● Contestants are expected to access the Online Judge system for EJOI’2020 via a computer with Internet access.
    ● Reference materials (written, printed, or digital forms) are not allowed. All the leftover files before each contest must be removed.
    ● Exceptions may be made for physical (printed) dictionaries.
    ● During the contest, contestants should not (directly or indirectly) access any online resources.
    ● During the contest, C++(STL) or Java documentation can only be used if they were downloaded beforehand.
    ● During the contest, there should not be any communication with another individual(s) unless permitted by the appointed proctor.
    ● There will be no online scoreboard during the contest, neither for the contestants nor the leaders and proctors. Final results will be posted after each contest day.
    ● Any suspicions of cheating will be investigated accordingly.


  • ● The team leader is expected to be responsible for enforcing the Online EJOI’2020 Contest Rules for her/his team. Every contestant is expected to be physically invigilated/proctored by the team leader or an adjunct appointed by the team leader.
    ● The team leader/adjunct must not have any conflict of interest with the performance of the participant. For example: parent/sibling of a contestant, (main) coach of contestant(s).
    ● Proctors(adjuncts) must also be registered in the EJOI Registration System.
    ● There must be at least two proctors per contest site to enforce the contest rules.
    ● There must be at least n+1 proctors if n contestants are at n different sites.
    ● Only the +1 can be offsite.
    ● Rationale: contest site must not be left un-proctored at any time during the contest, e.g., if the proctor has to go to the toilet.

Contest Sites

  • ● Each team can establish either a single (preferred) or multiple ‘contest-sites’ as per local government requirements on 02-06 September 2020, each with one or more contestants participating. There is no restriction on the venue of the site as long as all the rules are adhered to. Here are some examples of possible candidates for contest-sites:
    • 1. Computer Laboratory in local universities/schools
    • 2. Meeting room within a corporate office
    • 3. Leader’s or participant’s place of residence (only in case if isolation is enforced due to COVID-19)
    • 4. Conference room in a hotel
  • ● Every contest site should have the following setup:
    • 1. Computers with Internet connectivity. One is required for each participant. Spares are highly recommended. Details on the hardware and software specifications of the computer can be found in the later section.
    • 2. Sufficient equipment and connectivity for the onsite proctor to engage in a video call (preferred) or at least web messaging with the host organizing team throughout the contest for emergency cases.
      • - Adequate camera setup showing the participant (e.g. (laptop) webcam, external webcam, smartphone camera).
      • - Adequate audio setup allowing the proctor to converse with the host organizing team on the video-call (e.g.: speakers, headsets, microphones). Every video-call participant must be visible at all times otherwise they will be removed from call.
      • - Rationale: in the event of emergencies, a local onsite proctor is supposed to contact the host operation team for help and let the contestant continue working on the task (possibly offline).
      3. Ability to record and store video footage of the contest site, showing the physical movements of each participant. Each team will be given a private Google Photos album where they will share their recordings with us.
  • ● For the avoidance of doubt, the below features of a typical EJOI are allowed, but not required (optional):
    • 1. Participants can bring snacks, food and/or mascot.
    • 2. Printing services must be available (sheets printed are to be checked by the proctor before given to the contestants).
    • 3. File backup system to migrate contestant’s work during a machine failure.
    • 4. Network and power redundancy systems.
    • 5. External keyboard and mouse.

The Recorded Videos

  • ● Locally recorded video feeds of the room (multiple camera feeds, at least two) and screen recording of each participant
  • ● Minimum requirements:
    • Must be able to see all of the screens
    • Must be able to see all of the faces (including the presence of at least one proctor at all times)
    • Screen recording should have enough quality to verify that participant is not violating any rules: full display, at least 5 frames/second, at least 640x360 output resolution, no audio
    • Must be able to see a local clock
  • ● Rationale: To provide enough material for checking if there is suspicious case of cheating
  • ● Videos must be able to be used to determine the following:
    • Are contestants at their computers?
    • Are there any proctors in the room at all times?
    • What is the contestant doing on their screen and desk?
    • What is the current local time of any event (e.g., contestant leaves briefly to the toilet)?
  • ● There must be sufficient (social distancing) separation between contestants in the contest site so that contestants cannot look at each other screens/written workings from their seat
  • ● Video must be sent to EJOI host after the end of each contest (by end of the contest day)
  • ● Recordings will only be accessible by the host and will be deleted one month after the conclusion of EJOI’2020 Georgia (Online Competition) on 7 September 2020, that is, all videos will be deleted by 7 October 2020.

  • Important: Hardware/network/electrical failures are the responsibility of the team, and will not be grounds for extra time. Please provide spares for redundancy.
  • Notes
    • There is no restriction on Operating Systems and IDEs. It is recommended to install what the participants are familiar with.
    • (As of today) There is no Operating System image provided by EJOI’2020 HTC.
    • It is strongly discouraged to use the participant’s personal computers for the competition unless absolutely necessary (see the scenario for participant A in Sample Configuration B). Sensitive information may be accidentally recorded in the screen recordings.
