1.10

Thanks! I haven't looked into the concept of gun heat waves that much yet, but it's interesting, especially in melee where it's a bigger challenge to detect enemy waves.

What I changed in 1.10 is actually concerning the gun. Firestarter fires a virtual bullet wave each tick now. Apparently this speeds up learning and it increased the performance of the guess factor gun, even against surfers.

I am curious about your new version! And I agree, I am happy to see so many people active, and I wonder where this activity suddenly comes from. Maybe AI and Deep Learning becoming popular in the media also sparked new interest in Robocode.

Ah, ok. I thought it would be movement related, and perhps you are doing some kind of shrapnel dodging.

A good way I found to get a balance between the every-tick vs fire-only is to use "time to/from fire" as an attribute, this way you get the fast learning as well as the better targeting of bots that react to enemy fire once you have enough data.

Happy robocoding!

IMO, bots using precise prediction (1v1) can also be called shrapnel surfing ;) e.g. ScalarBot is avoiding some "Virtual Bullets" with equal weights using true surfing, but that works similar to shrapnel surfing with anti-gravity. IMO the real difference between traditional wave surfing and shrapnel surfing is whether you are avoiding some "shrapnel" or just minimizing some probability (mostly from VCS bins or trees).

BTW, are you trying to avoid bullets using minimum risk before recent updates? Or just traditional minimum risk like HOF & Diamond.

There are lots of possible styles of minimum risk movement. I think Diamond detects a new minimum risk point every tick. HOF detects a new point once he reaches the previously detected point. So the frequency of detecting a new destination makes a difference and it can greatly affect your bot's behaviour. What Firestarter did before recent updates was calculating the minimum bullet flight time from enemy guns and updating his destination in that frequency. It is imprecise but it usually tricked all simple targeting systems quite well.

Well, that trick sounds awesome! Never thought that something imprecise could work so well in melee ;) Maybe melee is a really different battle field from 1v1, where everyone can only have imprecise information. Then even some guess works pretty well.
