We would also like to thank several volunteers who made this programming contest possible. VSoE made the labs available for the contest, and provided competent technical support. Darryl Deweese, Ryan Brown, Aadarsh Patel and Liang Huang helped develop the problems and standard inputs/outputs. Cheng Lu made a good preparation for the environment set-up with John Ng, and communicated with the contestants and helped with judging. Aadarsh was a super efficient judge during the contest, taking over most of the judging and clarification. Zhan Shi came and talked to the contestants during the ceremony. Michelle Forcier and Anita from ACM organized check-in and photo-taking. Ravi and Anita stayed with the contestants throughout the contest. Prof. Kempe supervised the whole procedure and gave us lots of suggestions.
