Final Report

November 4, 2017

The 2017 ACM ICPC East Central North America Regional Programming Contest (ACM ICPC ECNA RPC) was held on Saturday, October 28, 2017. We had 139 teams from 49 colleges and universities throughout western Pennsylvania, Ohio, Michigan, eastern Ontario, and Indiana (excluding the Greater Chicago Metropolitan Area).

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 three issues of note. Some observations:


There were three issues of note during the contest.

It was noted that the IDEs were sluggish to load and would sometimes freeze during loading. It was also found that the IDEs could often be coaxed into loading by successively starting and stopping them. This issue will be examined in more detail as soon as is practical in order to avoid this problem in the future.

One site had an issue with contestants’ machines locking up, necessitating a reboot. While this delayed many of the teams at the site by anywhere between 2 and 9 minutes, a review of the final standings indicates that the standings would not have been different had there been no delay.

During the contest, Kattis had two periods when it was either sluggish or unable to communicate. During these periods, teams could continue their work but not submit any solutions. The first occurrence happened at about 2:40:00 and lasted about ten minutes; the second occurrence was at about 3:30:00 and lasted about 20 minutes.
