Diamond - Version History - Code

---

• 1.31 - 8/28/2009
  • Slightly tweaked kernel density calculation in Melee gun. (Not much score change, but feels more right to me.)
  • Changed how Melee gun aims when it is hot (4+ ticks before firing):
    • 1.30 left the target selection code in place and aimed at that target with HOT when the gun was hot.
    • Now, completely ignore the target selection, and just aim at everyone every few ticks while the gun is hot.
• 1.30 - 8/27/2009
  • MeleeRumble ‒ APS: 68.29% (2nd*), PL: 276-2 (2nd), Survival: 92.77%
  • RoboRumble - No 1v1 changes.
  • Attempt at a Melee gun that targets everyone at once (a la Shadow/Melee Gun).
  • Notes: This is the second time I've tried to implement this, and I think this time I have it working right. It hasn't been producing incredible scores in my test bed, though, so I'm skeptical how well it will perform before I tweak it a bit more.
• 1.29 - 8/26/2009
  • MeleeRumble ‒ APS: 68.14% (3rd), PL: 275-2 (3rd), Survival: 92.39%
  • RoboRumble - No 1v1 changes.
  • Slightly decreased randomness of the Melee movement.
• 1.286 - 8/25/2009
  • MeleeRumble ‒ APS: 68.03% (4th*), PL: 275-1 (2nd), Survival: 92.05%
  • RoboRumble - No 1v1 changes.
  • Removed new gun dimension.
• 1.285 - 8/25/2009
  • MeleeRumble ‒ APS: 67.68% (4th*), PL: 274-3 (2nd), Survival: 91.47%

  • Added a heading relative to center of battlefield dimension in gun.
• 1.284 - 8/24/2009
  • MeleeRumble ‒ APS: 68.03% (4th*), PL: 273-3 (3rd), Survival: 92.18%
  • RoboRumble - No 1v1 changes.
  • For gun waves originating from enemies:
    • Don't fire from location of the enemy being targeted by the wave.
    • Calculate real wall distance, based on (enemy) wave source location. (1.283 just copied the wall distance values from the gun wave originating from Diamond.)
• 1.283 - 8/23/2009
  • MeleeRumble ‒ APS: 67.45% (4th*), PL: 272-4 (4th), Survival: 91.41%
  • RoboRumble - No 1v1 changes.
  • During melee, fires and collects gun waves from locations of every enemy bot, not just from Diamond's location.

    • In calculating wave surfing dangers, change number of scans used from Math.min(scans, CLUSTER_SIZE) to Math.min(Math.ceil(scans / 5), CLUSTER_SIZE).
  • Gun:
    • Added accel dimension.
    • Gun heat dimension uses firing-tick gun heat instead of aiming-tick gun heat.
    • Always use gun heat = 0 when aiming.

  • RoboRumble - No 1v1 changes.
  • Only factor in perpendicularity and don't-be-targeted risk factors in certain situations (per-enemy).
  • Use cosine-based formula for perpendicularity. (I do it this way in BrokenSword, but thought of it as a code size trick. Recently concluded it's actually more correct anyway, as it models lateral velocity.)
• 1.161 - 6/1/2009

  • Rollback to 1.122.
  • Myriad changes to Wave Surfing:
    • Tracking normalized enemy hit percentage as in Dookious, used for making lots of decisions.
    • For the recent scans taken into account, uses the last X hits instead of clearing the recent scans every few rounds. Also only enables this when enemy hit-% is above a certain threshold.
    • Distancing based on Dookious (instead of just using desired distance = 525 all the time).
    • Added a flattener, enabled with similar conditions to Dookious, but permanently enabled once it is enabled.
    • Against very simple targeters, only use 3 DC dimensions.
• 1.15 - 5/30/2009

  • RoboRumble - No 1v1 changes.
  • Removed random direction change timer.
  • Tweaked risk from (Diamond's) recent locations.
  • Note: Best "bug-free" version in APS comparison. Only down .1% from 1.111 (w/performance enhancing bug), up .3% from 1.11 (bug fixed version). Good enough for me, so now I can move on with my life. =)

    • Fixed one more off-by-1 bug in the surfing (using my location from 3 ticks ago instead of 2).
    • Fixed the bandwidth used in kernel density calculations. (I'd set it to a static 0.1 as a placeholder, should be based on distance.)
