ACM ICPC Jakarta Rules

Team Composition

A representative of the sponsoring institution of higher education, typically a faculty member, must serve as or designate the team coach. The coach certifies the eligibility of contestants and serves as the official point-of-contact with the team prior to and during contest activities. A team may only have one coach and the coach cannot also be a contestant.

The coach must fully register teams in the ICPC Registration System ( no later than September 23rd, 2012 (for Indonesian team) and October 6th, 2012 (for foreign team). A team is not eligible to compete in the regional contest until the regional contest director has accepted the team in the web registration system. Teams failing to comply with any of these requirements will be ruled ineligible to compete. Only registered reserves may be substituted for contestants. Such substitutions must be entered in the ICPC Registration System by the regional contest director before the contest begins.

Each team consists of three contestants who are eligible to compete in the ICPC World Finals as described under Advancing to the World Finals in the Regional Rules. The team's contestants must satisfy the following eligibility rules.

Period of Eligibility

The Contest

Teams will compete to solve 8 to 10 algorithmic problems in 5 hours contest time.

Each problem has the following components:

You may find some example problems in UVa online judge (

Teams may ask clarification about the problems using the contest management system (INC: contest website; ICPC: PC2). If the judges agree that there is ambiguity in the problem, they will broadcast this clarification to all teams.


Teams should submit their source code using the contest management system anytime during the contest time.

A problem is solved when it is accepted by the judges. In order to accept or reject a submission, judges will compile and test the program with secret test data (only owned by the judges) which have been prepared in advance before the contest.

Each submission will get one of these responses from the judges:

  1. Yes - Accepted.
    The program produced the correct output within running time limit without any error. This program is accepted by the judges and the problem is considered as solved.

  2. No - Wrong Answer.
    The program did not produce the correct output.

  3. No - Runtime Error.
    The program crashed (runtime error) when processing the secret test data.

  4. No - Time Limit Exceed.
    The program took more than time limit to produce output and terminate correctly.

  5. No - Compile Error.
    The submitted source code cannot be compiled.

No other details will be given to each response.


Teams are ranked according to the most problems solved. Teams who solve the same number of problems are ranked by least total time. The total time is the sum of the time consumed for each solved problem (in minutes). The time consumed for a solved problem is the time elapsed from the beginning of the contest to the submittal of the accepted run plus 20 penalty minutes for every rejected run for that problem.

The top 50 teams from INC 2012 will advance to ICPC 2012 Jakarta Site. The winner (and possibly also 2nd or 3rd rank, depends on ICPC Asia Director) has the chance to advance to ICPC 2013 World Final in St. Petersburg, Russia.
