YersiniaPestis/VersionHistory

Version 3.1 Download link

• RoboRumble ‒ APS: 82.73% (16th), PL: 737-4 (2nd), Survival: 90.67%
• MeleeRumble ‒ APS: 64.07% (16th), PL: 258-17 (18th), Survival: 84.76%

Overall:

• Refactoring.

One on One:

• Faster wave surfing.
• Merge danger in a crowd targeting fashion.
• More distance control.
• More conservative firepower selection.

Results:

• Worse in every sense.

Melee:

• Minimum Risk:

• Bigger radius for the point generation.
• Cap the radius to the distance of the closest bot.
• Added bullet hits to the risk calculation.
• Store my own positions every 7 ticks instead of 3.
• Better risk calculation, and better tuned.
• Implemented corner grabbing:

If there are 4 or 5 opponents and I'm not close to a corner, use the corner with lowest risk as the center of the point generation instead of myself.

• Check the risk of the point that is going backwards 1 pixel, to simulate a how risky is to stop.

• Melee Gun:

• Fixed bug that weighted bots with more energy higher.
• Guns are now on a virtual gun array, tracked with a wave and use distance as a measure of how good a gun is, as opposed to 1v1 where only exact hits count.
• When aiming the gun now use the virtual gun array stats to weight each of them.
• Faster aiming for enemies with energy_ equal to 0.
• Better energy management.

Results:

• Big increase, very close to what was expected.

Version 3.0 Download link

• RoboRumble ‒ APS: 83.2% (11th), PL: 735-1 (1st), Survival: 90.94%
• MeleeRumble ‒ APS: 60.87% (40th), PL: 235-41 (41st), Survival: 77.75%

Overall:

• Rollback to version 1.3.7.
• Some refactoring.
• Removed buggy attributes (were always set to 0).

One on One:

• Slightly faster gun.
• Ignore bullets that hit other bullets when aiming with the normal gun.
• Minor tweaks to AS gun weights.

Results:

• Very similar to 1.3.7 overall, but is more of a surfer killer.

Melee:

• Completely new Melee code.

• Dropped Anti-Gravity Movement and used Minimum Risk Movement instead.
• Gun calculates hot, linear and circular for all enemies and aims using the strategy described in Shadow/Melee Gun.

Results:

• Decent start for the new code, but I have nothing to compare to yet as version's 1.1 melee code was very weak.

Version 2.2 Download link

• Rumble position: 62. date: 07/29/09
• Premier League position: 20. date: 07/29/09

• Very simple dynamic distance choosing.
• Results:

Version 2.1 Download link

• Rumble position: 41. date: 07/26/09
• Premier League position: 13. date: 07/22/09

• Changed preferred distance from 450 to 400.
• More aggressive fire power management.
• Results:

• Worse APS, maybe better PL, hard to compare, but and interesting results is that even when the difference between them is very small, there is a per bot fluctuation, ~+23 is the best improvement and ~-14 the worst decrease,so there is hope to find an easy way to get a close to best result of each one.

• Very precise wave surfing.
• Results:

• Terrible drop in APS and PL.
