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:

The ECNA RPC was successful, with only two issues of note. Some observations:


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.
