After they completed the training they put it up against real veteran pilots and the AI basically did a few things. It would take evasive maneuvers when fired upon and fire when in optimal range. That's pretty much it. And you know what? That's really all modern pilots need to do. It's amazing what they did with Top Gun, making this stuff not look boring. In the end of the day it's just wait for some computer to tell you that you have target lock and press a button. If attacked, take evasive maneuvers and pray. Takeoff and landing on a Carrier is the scariest part.
I'm quite curious how this system would perform in WWII era dogfights where you had to worry about the stress on your plane, had to deal with engines that failed and stalled all the time and maneuvers that were much slower and closer to the enemy (plus no missiles).
Even so, I enjoyed reading the paper (not the article) so would recommend it if you're into Game AI at all.
