That's really cool, I didn't see that! I also built a bullet power simulator that took into account discrete firing, bullet flight time, etc. However, it didn't use tree search: I just did monte-carlo rollouts of running it a couple hundred times and averaging the results, so it's probably much slower than yours! It's not used in BeepBoop, but I did use it to validate that BeepBoop's fast estimates assuming continuous time, normal distribution for hitrate, etc. were about right. For example, here and here are some plots showing that BeepBoop's approximations work pretty well, although not perfectly and with some edge cases (it says file uploads are disabled so I can't add them to the wiki). I sometimes see interesting emergent behavior from BeeBoop like firing high-power bullets when it's losing, presumably either to get more bullet damage and take less bullet damage before it dies or in the hope that a lucky high-power hit turns things around.

I think I got uploading working... give it a try and let me know.

This new bot of yours really is awesome ! It is really beating the hell out of the topbots, even without BulletShielding.

Alas I am not able to run any battles for it, as I am still on Java 8.

Thanks! I will make it Java 8 compatible for the next release.

Just wanted to add to this thread, this robot truly is a beast! Congratulations on 100% PWIN!

alas, in version 0.11, still some parts are not Java 8 compatible: kc/mega/game/Battleffield has been compiled by version 57.0.
Does not matter that much, I am just not able (currently) to run any battles for it. Same for Raven as it has been compiled by version 55.0.

Oops, I will have another go at fixing it for my next release!

I've downloaded Java 13, I can now run battles for BeepBoop. After rebuilding the robot-database, also Raven and WaveShark run fine. Note that for my development I will still use the compiler option '-source 1.8'

Ok, great! I compiled 0.11 with --release 8, but I think it didn't work because there were some old .class files lying around that didn't get overridden.

Oh wow, missed this! Awesome work Kev, you have a history of popping up with surprise entries =)

I'd be curious to know more about the Tensorflow work you did to make the KNN features...

Thanks! I wrote a brief description under BeepBoop/Understanding_BeepBoop, but I'll release the code too once I get it cleaned up.

Aha, I missed the last section. Surprised there wasn't more to gain from some kind of deeper embedding model.

Me too, and I'll maybe revisit it at some point. Theoretically a deeper embedding model could learn feature interactions like "wall-ahead is more important when velocity is 8 than when it is 0"

I’m surprised as well. Btw, how many layers are you using in the deeper model? And is that fully connected? I guess some deeper models with explicit feature interactions may work better in robocode scenario, given high noise. I would try things like Deep&Cross, DeepFM, etc.

It's possible that the KNN already takes that into account sufficiently. Maybe if you bump the cluster size up a lot, and change the kernel width for cluster weighting, it might force this part of the learning into the NN instead?

Yeah, very cool to see! Congrats from me, too! And I'm enjoying reading about it.

Hey Voidious, long time no see! Glad you enjoyed reading about it, I learned a lot from Diamond's code while developing BeepBoop.
