Midboss - Version History

---

• 1q - 19/01/2010
  • Increase depth of 'precise prediction' (very different meaning than surfing) in the score prediction code, to be somewhat greater than version 1k (versions after 1k had it reduced a fair bit). Some tests indicate that this should fix the score loss since version 1k finally.
  • Sparsely allocate gun buffers as needed, instead of allocating all 164250 VCS buffers (each having 45 bins of double type) at once...
    • Let's see... 164250*45*8 = 59130000 bytes = 56MB + Java's overhead per array... Ouch :P
    • This greatly reduces memory usage, to 1/10th of prior usage, since in a typical battle only about 10% of those VCS buffers actually get written to anyway ;)

• 1p - 19/01/2010
  • RoboRumble ‒ APS: 83.06% (11th), PL: 728-23 (18th), Survival: 90.85%
  • Fix some bugs in the 'firepower selection'/'score estimation' code.

• 1o - 18/01/2010
  • RoboRumble ‒ APS: 82.86% (13th), PL: 731-20 (16th), Survival: 91.97%
  • Improve the hitrate estimator algorithm notably
  • Make some weird rare NaN bug in the surfing not cause infinite loop

• 1n - 18/01/2010
  • RoboRumble ‒ APS: 82.83% (13th), PL: 721-31 (31st), Survival: 92.15%
  • Anti-bullet-shielding tweak
  • Other minor tweaks... Seeing how much of score loss was random chance

• 1m - 16/01/2010
  • RoboRumble ‒ APS: 82.89% (13th), PL: 725-25 (20th), Survival: 92.07%
  • Fix various major bugs in 1l, should be good now...

• 1l - 16/01/2010
  • Pulled
  • Improve accuracy of score prediction by using real statistical approximation with normal distributions for the approximation that's used when unable to simulate deeply.

• 1k - 13/01/2010
  • RoboRumble ‒ APS: 83.37% (11th), PL: 733-19 (16th), Survival: 91.54%
  • Noticed issues against rambots happening again, and rethought some overcomplicated parts of the firepower calculation. Should work better now.

• 1j - 13/01/2010
  • Pulled
  • Fix some minor little bugs/inaccuracies in the score estimation code, particularly for the endgame and infrequently firing bots
  • Add a new "Low segmentation slow rolling" gun buffer

    Old gun buffers were:

    • "High segmentation no rolling"
    • "High segmentation fast rolling"
    • "Surfing buffer simulator" (ends up getting negative weight against surfers)

• 1i - 12/01/2010
  • RoboRumble ‒ APS: 82.98% (12th), PL: 732-19 (16th), Survival: 90.95%
  • Fix yet another minor bug in firepower selection
  • Improve enemy wave detection to have a check for gunheat like RougeDC does, this seems to fix Rambot performance

• 1h - 11/01/2010
  • RoboRumble ‒ APS: 82.78% (15th), PL: 731-20 (16th), Survival: 91.19%
  • Add fancy code to ensure that static data is garbage collected at end of battle, because apparently Robocode doesn't do this right
  • Fix some bugs/inaccuracies in the score estimation code.

• 1g - 10/01/2010
  • Bad results
  • Fixing various flaws that remained in version 1f.

• 1f - 09/01/2010
  • Bad results
  • Fixing a terrible bug in version 1d's new code.

• 1e - 09/01/2010
  • Bad results
  • Adding some new bullet power selection.

• 1d - 09/01/2010
  • RoboRumble ‒ APS: 82.73% (15th), PL: 732-20 (16th), Survival: 91.55%
  • Added a couple more segments.

• 1c - 08/01/2010
  • RoboRumble ‒ APS: 82.38% (16th), PL: 730-22 (17th), Survival: 91.13%
  • Basically RougeDC's movement with SaphireEdge, and RougeDC's firepower selection.
