IEEEXtreme is a global challenge in which teams of student members, supported by an IEEE Student Branch, advised and proctored by an IEEE Member, compete in a 24-hour time span, starting on October 14, 2017 at 00:00 UTC and ending at 23:59 UTC, against each other to solve a set of programming problems.
The competition was created to:
Other benefits include providing Student Branches with ways to get IEEE Student Members involved in local activity in a fun and engaging way.
The IEEEXtreme Programming Competition is hosted by The Institute of Electrical and Electronics Engineers, Incorporated, 445 Hoes Lane, Piscataway, New Jersey, USA, 08854 (“Sponsor” or “IEEE”). It is organized and managed by the Student Activities Committee under the Member and Geographic Activities business unit of IEEE.
Participants must compete as part of a team. Teams are comprised of up to 3 IEEE student or graduate student members, but can only include a maximum of 2 graduate student members per team. All team members must be IEEE student or graduate student members to register and compete in the competition. IEEE Membership numbers are required during the registration process. All team members must be over the age of 18. Universities and Colleges can have multiple teams.
Each team must have a proctor who will supervise during the 24-hour programming competition and each team is responsible for locating one or more eligible Proctors (see below) prior to registration.
Team members must solve and complete the problems without assistance from other people or prewritten code. Please note that the intent and spirit of the competition is for the students, not others, to solve a problem. Persons acting as Proctors must limit the level of support and must not contribute in any other form that might be considered original authorship, or in any way that may enable claims of rights or ownership to the submitted entries. In no case will work-on-behalf of teams or individuals be allowed. Sponsor reserves the right to analyze all submissions for plagiarism and disqualify or deduct points from any team in its sole discretion if the team’s work is not its own.
Void where prohibited by Law. Entrants understand that Sponsor may substitute or withhold prizes as required by law.
Registration will be open until October 4, 2016 (00:00:00 UTC). Registrations received before or after this period are void. Sponsor’s computer is the official time-keeping device for the contest.
Teams can find registration information at http://www.ieee.org/xtreme/
Each team must have a proctor to supervise competition activities.
Proctors must be an IEEE Member of higher membership grade. Student or Graduate Student Members are not allowed to proctor, but are encouraged to participate as a team member in the competition.
Proctor information (IEEE Member Number) is required during the registration process. Student Branch Counselors or Department Chairs make great Proctors as they are all higher grade IEEE members. Many IEEE Young Professionals are also higher grade IEEE members and may be eligible to serve as proctors. Teams may want to recruit two or more proctors so that one can take a break to rest during the 24 hour competition.
Proctor tasks include:
If you need assistance in finding a proctor, please consult our Guide on Finding a Proctor (PDF).
Please note: A Proctor can support up to 8 student teams and all of the competition participants under an individual Proctor’s supervision must compete in the same venue. For more information on venue, see the following section.
As IEEEXtreme is a virtual online competition, a physical location, or venue, must be identified for each team to use during the 24-hour competition.
Venues can be in an IEEE Student Branch office or a college lab or another location on campus. It must be a place that participants can use for the entire 24 hours during the competition and should be equipped with at least one computer and some type of connection to the internet. Each team must have at least one Proctor physically located within the venue at all times throughout the 24-hour competition
Student Branch Activity
Student Branches, if able, should support and help to the participating teams, helping locate an appropriate venue for use during the competition, promoting the competition, assisting in identifying appropriate proctors, and increasing awareness of the student branch presence on campus.
Students attending universities who do not have an IEEE student branch on campus can still participate in the IEEEXtreme competition. This is an opportunity to bring students together to have fun with IEEE activities. Consider using this opportunity as a way to form a student branch. More information on how to form a student branch can be found here
Problems are developed and judged by expert programmers. All entrants agree and acknowledge that Sponsor is the owner of all problems and any associated code. Entrants further agree that they will not use the problems or any associated code for any reason other than the competition without written permission from Sponsor. The panel of judges is made up of higher grade IEEE members from both Academia and Industry backgrounds. Problems will be categorized as easy, moderate, difficult, advanced, and Xtreme to allow for students of all experience levels to participate.
All of the problems can be answered in any of the supported languages, which are indicated in the table below. The time and memory limits are unique to every problem, and it is possible that certain programming language have a different time limit and memory limit, to adjust for factors such as virtual machine overhead.

A demo practice contest community, with sample problems from IEEEXtreme 10, can be found at: https://csacademy.com/ieeextreme-practice/.
Teams should submit their problem solutions electronically using the contest management tool. Instructions on access and utilization of the contest management tool will be provided to teams after registration closes.
The 2017 contest problems will be available the day of the contest.
30 points are awarded for correct answers. 70 extra points can be awarded depending on problem difficulty. The difficulty of any problem comes from the average points teams scored on it; should many teams solve the same problem, that problem is determined to be easy and no additional points will be awarded. However, few teams solve a problem the problem will be deemed hard and will be credited with additional points. This scoring schematic makes the competition and your placement within the ranking very dynamic. It is strongly advised you not to share your solution with other teams, as it will harm your score.
Note: Time is not directly included in the scoring formula. It’s purpose is to break ties, so teams that solve the same set of problems, only quicker end up higher in the standings. Since there is no penalty for the number of times a team submits a solution, it is recommended teams try to solve the tasks as quickly as possible
The exact formula for calculating the points value of a problem:
Average Points can be a number between 0 and 1, where 0 represents tasks that no one solved, and 1 represents tasks that all users solved.
Problems contain more than one test case. Those included in the sample will carry less weight whereas hidden cases will carry more weight on a varying degree depending on difficulty.
The higher number of solved cases a team submits, the higher the score will be. Therefore, should a team solve 3 out of 5 possible cases, while another team solved 5 out of 5, the team solving 3 would receive partial credit for that problem.
Rank is decided upon score. However, terms of draw time will be considered as a factor to rank teams. Ex: Team A and Team B can have same score, let’s say X, but then have different ranks, say Rank 2 and Rank 3. This means the Team with higher rank was faster to solve problems compared to the other team.
Time is of the essence. Submission time will be utilized to determine tie breakers.
To calculate the total submission time for the example, we consider the best submissions for each problem. For problem 2, the best (and only) submission occurred 2 hours into the contest. For problem 1, the best submission occurred 3 hours into the contest. Note that if an identically scoring submission occurred later, we use the earliest of these identical submissions. Therefore, we ignore submission number 4 and 5 because neither of these were an improvement over submission number 3. In this case, then, the total submission time for the team would be 5 hours.
Submission time for each problem is calculated at the beginning at the release of each challenge, not at the start of the competition.
No programming language has an advantage over the others. (Ex: Java, C, Python, PHP, etc. are all equal).
Scores will be impacted only by submissions, compiling will not affect scores.
Due to the dynamic nature of the scoring schematic, scores may fluctuate throughout the competition. Teams are encouraged to check in often to review their standings.

Selection of Winners
Winners are determined strictly based on overall score as determined by the scoring outlined above. As noted above, in the case of a tie, time will be considered as a factor to rank teams.
Notification of Winners and Final Rankings
From the close of the competition through 31 October the IEEEXtreme Technical team will be evaluating code submissions. IEEE reserves the right to disqualify a team if it’s found to have manipulated or cheated during the competition. The official results will be communicated on or about 2 November. Winners will be contacted by IEEE directly.
Requirements of Winners
IEEE may, within its sole discretion, require each member of each prize winning team to sign and return an affidavit of eligibility and liability and publicity release, in which each winning member consents to the use of his or her name, age, hometown and photo by IEEE for advertising and promotional purposes, without any additional compensation, wherever lawful, as a precondition to award of a prize. If any prize winning team member fails to sign and return the requested affidavit of eligibility and liability/public release as requested by IEEE, that team member may be disqualified, and his or her prize will be forfeited. In the event an entire team fails to sign and return the requested affidavit of eligibility and liability/public release as requested by IEEE, an alternate winner will be chosen using the methods described above. IEEE may also require each winner to assign all rights in any submission that is chosen as a winner to IEEE as a precondition to award of a prize. If any prize winner fails to assign all rights in the selected submission to IEEE, the winner may be disqualified, and his or her prize will thereafter be awarded to an alternate winner from the remaining valid entries using the criteria specified above. All prizes, including the travel arrangements for first place winners, must be claimed within one calendar year of the competition.
Teams affected by OFAC policies who are interested in competing in the contest may still be eligible to compete but understand that access to prizes may be modified or removed by law.
All active participants in the competition will receive a digital certificate and digital gift. “Active participant” is described as a team who makes a reasonable attempt at solving a problem in Sponsor’s sole discretion.
