This blog describes how the ICPC scoring system works. Teams are ranked by:
- Score
- Number of problems solved.
- Higher is better.
- Penalty
- In case of tie, the penalty is considered.
- Penalty is the sum of the times at which each problem was solved.
- For each incorrect submission, a penalty of 20 minutes is added. Submissions with compile errors are not considered for penalty.
- Note that only problems which are solved are considered for calculating the penalty.
- Any extra submissions for a problem after it is solved are ignored.
- Lower is better.
- If a tie still remains, the time at which the last successful problem was solved is used. Lower is better.
