Removing all your bots ?

Agreed, please don't drop everything. Clearly you're smart and a good programmer, and even if you aren't cracking top 10 (out of over 1000!) please don't be demotivated. I bet there are a few bugs that are lurking somewhere in your code that if you found them would instantly give you a 20 position boost. Just ask User:Chase-san about his experience with Seraphim.

I also started Robocode in high school, and it really shaped my whole understanding of geometry, statistics and more and has eventually impacted where I work and a lot of my understanding about software design, when calculations should be approximated and when a high accuracy version is required, etc. Robocode is definitely the best studying tool I have ever come across.

For me, at least early on I got the most satisfaction from the microrumble - having the codesize limitation meant that there were less moving parts and it was small enough to keep the whole thing in my head while I internalised all of the physics, strategies etc. I still think there are major gains to be made in minirumble, and the nano/micro/mini melee rumbles are also very neglected. Maybe you would find more enjoyment in the codesize limited divisions? The megabot scene isn't for everybody.

Thank you for motivation. Robocode is the best game I’ve ever seen. It is so perfect that I started to tune my bots one hour after I decided to give a break. I’ve already found a bug and will try the micro division. I won't re-upload them since most of them are modular BasicGFSurfers.
