East Central North America Region

The 2011 ACM-ICPC East Central North America
Regional Programming Contest

Final Report

The 2011 ACM-ICPC East Central North America Regional Programming Contest (ACM-ICPC ECNA RPC) was held on Saturday October 22, 2011. We had 122 teams drawn from 60 colleges and universities throughout western Pennsylvania, Ohio, Michigan, eastern Ontario, and Indiana (excluding the Greater Chicago Metropolitan Area). There was an additional 4 teams who had registered but did not participate and were canceled.

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: Cincinnati Site in Cincinnati, Ohio, USA (33 teams from 16 schools); Grand Valley Site in Allendale, Michigan, USA (18 teams from 8 schools); Windsor Site in Windsor, Ontario, Canada (25 teams from 13 schools); and Youngstown Site in Youngstown, Ohio, USA (46 teams from 23 schools).

We are pleased to report that the ECNA RPC was successful this year. Here are a few comments and observations:

1. Version 9.1.6 of the PC^2 Contest Control System was used to run the Contest. There were no technical problems and the contest went very smooth.
