Preliminary Report and Results
October 27, 2019
A link to the 2019 ECNA final report is forthcoming. Preliminary information follows.
As it was difficult for some teams in the ECNA region to travel to a single site for the contest, the ECNA RPC was held as a distributed contest. There were four contest sites:
- University of Cincinnati in Cincinnati, Ohio (26 teams from 11 schools)
- Grand Valley State University in Allendale, Michigan (22 teams from 8 schools)
- University of Windsor in Windsor, Ontario (24 teams from 8 schools)
- Youngstown State University in Youngstown, Ohio (43 teams from 16 schools)
The ECNA RPC was successful, with only two issues of note. Some observations:
- The software environment was modeled after the specifications given for the 2019 ICPC World Finals. Only minor modifications were made to account for hardware differences and matching the C++ standard to what Kattis uses.
- 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 11 problems with 89 teams solving at least one problem. The maximum number of problems solved by any team was 11.
There were two issues of note during the contest.
Three clarification requests between 01:55:00 and 02:40:00 alerted the judges to a problem with the judging data to problem B (Bio Trip). Four test cases turned out to have multiple roads between junctions; the input is insufficient to determine the proper connection between roads in those cases. The problematic test cases were removed and all submissions to that point were rejudged. No failed submissions were due to the bad test cases and no standings changed.
After the problem set was distributed for printing, it was discovered that two problems did not specify the number of decimal places for input values. The online versions were corrected and teams were alerted prior to the start of the contest that a clarification would be sent at the start of the contest. A clarification was sent at the start of the contest alerting teams to the differences in the problem statements.
