Shrinking OculusMicro

The package is dsekercioglu.micro but it is a mini(856 bytes) right now. I am not very good at shrinking so can somebody help me please? Thank you.

To me it seems like you already shrinked the code quite well. There might be a few more tricks you could do, but I don't think you can get rid of over 100 bytes to make it micro. Maybe you can sacrifice some features, or take a look at some shrinking software, e.g. [1]

Thank you, It seems like it works but there is an error:

Could not find robocode/AdvancedRobot.class on Classpath
Could not find robocode/Condition.class on Classpath

I understood the error but not sure about what to do.

I am not sure either, I never saw this error before.

If it won't work, you could also try using other shrinking software, there are a lot of tools available.

First ideas:

You can use a simpler calculation for MEA.

Try compiling with JDK1.4, an old version of Robocode, and Jikes.

I've also used ProGuard to shrink Yatagan - it was a bit tricky to add the right stuff to the classpath and keep the right components 'open', but once it was set up it was easy.

(edit: more details) With the MEA trick and some try catches I got it down to 769. I also wrote the surfing algorithm with a for loop. Removed absoIuteBearing method since it was used only once. I feel like a professional. =)

That while (true) loop looks scary :P Pretty cool if it's working though. I am excited to hopefully see OculusMicro in the rumble soon :D
