Hi everyone,

I am a longtime competitive programmer but have just recently discovered 
Robocode which is honestly way more fun than the generic competitions I am 
used to. However, I was surprised by the lack of active online competitions 
(besides https://literumble.appspot.com which I think is a great and 
generous contribution to the community).

After a bit of thinking and tinkering with the Robocode "CLI", I decided to 
build an Arena <https://robocode-arena.com/> with a continously running 
ladder of robots. I have been experimenting with it for a month or so now 
and thought I'd share it with everyone here in case anybody is still 
Robocoding or wants to pick it up again.

I also figured it would be fun to see what the current LLMs are capable of 
when it comes to Robocode. So, I ran the following experiment 
https://robocode-arena.com/blog/ai-experiment which some of you may find 
interesting.

Thanks,
Billy
