Background Information

How competitive it is?

1v1 - #27 APS, #9 Survival, #10 PL

meleerumble - #8 APS, #8 Survival, #8 PL

teamrumble - #1 APS, #1 Survival, #2 PL

neoroborumble - #1 APS, #1 Survival, #1 PL

gigarumble - #9 APS, #5 Survival, #12 PL

meleetop30rumble - #8 APS, #4 Survival

Strategy

How does it move?
Multi-mode
How does it fire?
Guess factor targeting with dynamic clustering segmented data.
Using dynamic clustering/kernel density to estimate hit rate and choose bullet power. The idea is to search for peaks in kernel density and if one is found, switch to aggressive energy management, if not, then stick with survivability energy management. Working well in melee/team thanks to swarm targeting, shooting power 3 bullets against tight packs of bots, and owning rammers :) . Currently disabled in 1v1 to avoid wasting energy against adaptable movements.
How does it dodge bullets?
Old Skool shrapnel dodging.
Wave Surfing/Curve flattening.
Enemy virtual bullets generated with dynamic clustering segmented data in both modes.
How does the melee strategy differ from one-on-one strategy?
Anti-gravity in melee/team.
Multi-mode in 1v1
How does it select a target to attack/avoid in melee ?
Swarm targeting.
What does it save between rounds and matches?
Between matches: Nothing.
Between rounds: Wave data.

Additional Information

Where did you get the name?
From the Atari 2600 game Combat.
Can I use your code?

What's next for your robot?
  • Cool algorithms
  • Energy management with dynamic clustering segmented data for hit rate estimation. Should be cool to watch. DONE
