The Google-supported Planet Wars Google AI Challenge had over 4000 entries that used AI and game theory to compete against one another. C at the R-Chart blog analyzed the programming languages used by the contestants with some interesting results.

The usual suspects were the most popular languages used: Java, C++, Python, C# and PHP. The winner, Hungarian Gábor Melis, was just one of 33 contestants who used Lisp. Even less common were entries in C, but the 18 “C hippies” did remarkably well.

Blogger C wonders if Lisp was the special sauce:

Paul Graham has stated that Java was designed for “average” programmers while other languages (like Lisp) are for good programmers. The fact that the winner of the competition wrote in Lisp seems to support this assertion. Or should we see Mr. Melis as an anomaly who happened to use Lisp for this task?
