Portia - Version History

---

• 1.17 - 29 August 2009
  • Keeps statistics and shows them at the start of the match. Among other things, this means it will be more easy to see if Portia is malfunctioning. :)
  • Now using Rednaxela's kD-Tree
  • Hopefully fixed the NullPointerException bug Voidious pointed out...
  • Reverted bullet power selection back to 1.13, I want my 1% APS back! :P

• 1.16 - 23 August 2009
  • MeleeRumble ‒ APS: 67.43% (4th), PL: 274-3 (3rd), Survival: 92.61%
  • Rewrote the code I did in 1.14 and 1.15. Hopefully it won't cause exceptions anymore.
  • Removed the main exception handlers. That way exceptions won't be hidden and secretively cause problems in battles. (Fail safe)
  • As proof of concept: Now detects groups of the same robot using Head-On. Portia becomes 1st roughly 85% of the time against a group of 9 HawkOnFires now (compared to 60% before this update).
  • Slight changes to energy management (mostly rollback).
  • Slight change to DC-gun: uses squared distance instead of manhatten distance.

• 1.15 - 19 August 2009
  • MeleeRumble ‒ APS: 67.49% (3rd), PL: 275-1 (2nd), Survival: 92.17%
  • DC-gun bug fix. This is not the bug Voidious has reported about 1.14, I haven't been able to reproduce that one.
  • More aggressive bullet power use when at high energy.

• 1.14 - 15 August 2009
  • MeleeRumble - Back to 3rd place!
  • Several DC-gun changes for melee:
    • Use strong bullets against opponents who seem easy to hit
    • Do not use predicted positions that are outside of the battlefield
    • DC-gun speedup

• 1.13 - 11 August 2009
  • MeleeRumble - 2nd place!
  • RoboRumble - No 1v1 changes.
  • DynamicClustering accuracy increase (Hopefully). Instead of using interpolated velocities and turn rates, it now uses relative positions.
  • Made it more selective, accurate and aggressive with "simple" robots (cyan gun).

• 1.12 - 3 August 2009
  • MeleeRumble - 3rd place!
  • RoboRumble - No 1v1 changes.
  • It took me quite a while to understand the concept behind kd-trees, but I finally got it! Props go to ABC and Voidious for inspiring me to study the subject. I made my own implementation of the tree, and changed the gun to use it. I think there is still a lot to improve, but I was so curious to see the result so far I had to make a release.
  • Removed green exact pattern matching gun
  • Added yellow Dynamic Clustering gun. This gun is used instead of the blue circular gun when enough data is collected.

• 1.11 - 23 July 2009
  • MeleeRumble - APS:66.67 (5th), Survival:90.86, Glicko-2:1713.1, PL:548
  • RoboRumble - No 1v1 changes.
  • Changed the gun and added specific colors for shotlines:
    • Blue - primary circular targeting
    • Green - pattern match targeting
    • Cyan - simple bot targeting
    • Red - disabled bot targeting

• 1.10 - 23 July 2009
  • MeleeRumble - APS:66.76 (5th), Survival:90.95, Glicko-2:1718.5, PL:546
  • RoboRumble - No 1v1 changes.
  • Major bug fix: it turns out the gun was mostly firing using simple Circular Targeting. That's now changed to actually predict opponents accelerating and decelerating.
  • Cool feature: can now detect record & predict Oscillator Movement frequency.
  • Cool feature: can now detect most sample bots and bots behaving like sample bots. It uses powerful bullets against such robots, to maximize effect. :)
  • No significant changes to movement: That way it will be more obvious what the effect of the changes on the gun are. I only did some codespeed and distancing optimizations.

• 1.0 - 12 July 2009
  • RoboRumble - APS:66.28 (124th), Survival:75.35, Glicko-2:2149, PL:1226
  • MeleeRumble - APS:66.46 (6th), Survival:90.71, Glicko-2:1716.5, PL:542
  • Initial Release
