Yep, I agree on all those points.
Taking a few of the bots on the Open Source page might be a good start for replacing the "influential bots" list. Maybe list more current/past competitions, but with less description of each than what's there now. For movement/targeting techniques, maybe instead of mentioning all those Robocode-specific terms, we could just mention some of the machine learning techniques that are widely used, like KNN, kernel density, multi-variate histograms (VCS), pattern matching, and neural networks.
I'm torn as to whether the wiki deserves its own special mention besides the link below. It is a pretty strong part of the online Robocode community and a resource for anyone doing Robocode, but I'm not sure that means it deserves more than just a link near the top of "See also" or "External links".
Agreed on all, unfortunately I am super busy again and don't have time to help with this.
I think there should be some sort of heading called "Community" or something like that, where you list the RoboWiki and the SourceForge forums as well as the dev groups.
I agree, and I like your thinking. Could almost copy Open Source wholesale for that section, after converting some of the jargon.
I think a mention in the actual article to the Robowiki would be justified. It is where most of the developments and long running competitions originate (like RR@H). But it might just be at most a sentence like "A great deal of the innovation occurs around Robowiki[External Link], the games premier wiki."
Perhaps a short mention of some of the licensing that occurs in Robocode. Otherwise there isn't really much to say beyond what is already covered.
