Google AI Challenge 2010
Team Blue Iris (that's me!) placed 77th out of 708 in the Google AI Challenge 2010 contest. The contest was to design an AI for a Tron lightcycle game.
My entry used the standard min/max approach, similar to many other entries. I guess that's why it performed similarly to so many other entries. :-) I didn't have any time to investigate better algorithms, due to other obligations.
This contest was interesting because it went on for a long time (about a month) and because the contestants freely shared algorithm advice during the contest. This lead to steadily improving opponents. My program peaked at about 20th place early in the contest, but because I didn't improve it thereafter, its rank gradually declined over the rest of the contest.
The contest winner's post-mortem reveals that he won by diligent trial-and-error in creating a superior evaluation function. Good job a1k0n!
Congratulations to the contest organizers for running an interesting contest very well. I look forward to seeing new contests from the University of Waterloo Computer Club in the future.
