Possible errors

I still see low scores such as %5 against some bots and it seems like it isn't about the crowd part. I tried to fix it two times and it didn't work. I also tried to reproduce the error but it doesn't occur in my robocode 1.9.3.0. I didn't change anything but the normalised crowd thing. I would see if there was any IndexOutOfBounds Exception or Arithmetic Exception.

Don’t worry, ScalarBot is having the same bug, e.g. it scores near 0% against some opponents, which is never reproduced even after thousands of rounds.

Anyway, if that happens too much, you can try to catch every exception and log it to file, then look up the low scored opponents in the log. ScalarBot fixed a really rare bug in kd-tree by doing so.

Anyway, it still scores very low against some bot randomly, without throwing any exceptions,

I think I should worry. In my tests it does better than my normal gun but in the rumble it has about -3 APS. May it be the bug fixed with 1.9.3.0?

I got this exception after some testing.

This is a bug in Rednaxela’s kd-tree. I created a PR in his bitbucket a few years ago, but no response.
