After a great holiday season and a minor delay in judging, the results are in!
1st: Iron TicTacToe
2nd: HackerNews Sentiment Analysis
3rd: Iron Unfollow
Winner: Iron TicTacToe
Built by: David Jones
The parallel algorithm has 2 main parts. The first part expands the game tree. The second part passes the results from finished games (at the leaves) back up the tree towards the root. In the middle of the game tree search, some IronWorkers are busy expanding one part of the game tree while other IronWorkers are busy passing results up another part of the game tree. The algorithm finishes when all the results are reported back to the root, and an email is sent with the final solution.

3rd Place: IronUnfollow
Built by: Matthias Sieber
The purpose of IronUnfollow is to declutter the user's Twitter account. My goal was to get down the number of people I follow down significantly. Before I started writing this useful script, I was following over 2,000 people. Now I'm following less than 150 actual people and can actually see some meaningful and interesting tweets that make me want to interact with my following.
