Hint,Try subing in 0.999999 instead of one in 3n+1, use 3n+0.999999999.

It turns out it wouldn’t have made any difference if we had switched to Sun’s JVM. We did finally chase down what the problem with Java was. You can read all about it here: http://code.google.com/p/ai-contest/wiki/Sandboxing

Excellent work! I love the histograms. I am glad that at least one person is happy with the ranking algorithm!

Hello Jeff,

I have been playing around with an histogram representation of the results wishing to know what was the distribution of Win/Draw/Loss for a given player with respect to opponent final ranking. The results have been compiled in several gif animations (for several bin widths) here: http://pcsi.kleber.free.fr/AI_challenge/

In the normalized versions, it’s fun to notice that there is an inversion in the ratio %Win/%Loss just around the bin were the final rank of the player belongs, proof that your ranking algorithm was quite accurate and coherent.

If you ever wish to get access to the graphs for each player (in pdf or png format), just ask.

Cheers,
