Preliminary Report and Results
February 27, 2022
A link to the 2021 ECNA final report is forthcoming. Preliminary information follows.
Due to the global pandemic, this year's regional contest was held remotely. Teams could compete from wherever it was convenient for them to do so.
The ECNA RPC was successful, with one minor issue. Some observations:
- 96 teams from 30 schools competed.
- Contestants were allowed to use any available computing equipment, limited to one computer per team.
- We used Kattis again this year for the contest control system.
- The contest started promptly at 10am and ended at 3pm.
- The contest consisted of 13 problems with 62 teams solving at least one problem.
- The maximum number of problems solved by any team was 12.
Issue
There was one issue of note during the contest.
A clarification request at 03:09:09 alerted the judges to a problem with the judging data to problem J (Recycling). One test case turned out to have two possible answers, due to an ambiguity in the problem statement. The problematic test case was removed and all submissions to that point were rejudged. One submission had its judgment changed from Memory Limit Exceeded to Time Limit Exceeded. 11 submissions had their judgments changed from Wrong Answer to Accepted. The standings were updated during the contest and are reflected in the current standings.
