- 1.46 - 10/12/2009
- Fixed a bug in "smart cycling" code. (Used in some surf stats, removes point closest to point being added instead of removing oldest point.) Was using unweighted distances to find closest point.
- More changes and additions to recent scan views, going for some diversity in distancing formulas and decay rates.
- 1.45 - 10/11/2009
- MeleeRumble - Not entered.
- RoboRumble - Corrupted, but slightly above 1.444.
- Changes to recent scans surfing stats, and added a few more recent scan views.
- 1.444 - 10/9/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.23% (4th), PL: 732-9 (5th), Survival: 92.94%
- Normalize surf dangers by total weight given to scans in the wave.
- Moving away is safer the same way moving closer is more dangerous. (Note: previous design was a conscious decision, not an oversight.)
- 1.443 - 10/8/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.29% (4th), PL: 731-15 (10th), Survival: 92.91%
- Normalize surfing dangers by max weight given to any scan. No effect on relative dangers within one wave, but will hopefully make the two surfable waves be weighted more consistently.
- 1.442 - 10/6/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.28% (4th), PL: 737-8 (7th), Survival: 92.99%
- Rollback changes to surf scan weights.
- This should be 1.42 + some refactoring + two bug fixes.
- 1.441 - 10/6/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.64% (5th), PL: 725-19 (14th), Survival: 92.26%
- Another change to how scans are weighted by distance in surfing: divide by distance squared.
- 1.44 - 10/5/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.97% (5th), PL: 733-12 (9th), Survival: 92.8%
- Rollback surfing stats to 1.42.
- Change to how surfing weights scans by distance.
- 1.432 - 10/4/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.26% (4th), PL: 734-10 (8th), Survival: 92.95%
- Fixed a small bug in the k-means gun.
- Give less weight to second wave when flattener is on. (Same as Dookious.)
- More tweaks to surfing stats.
- Added several layers to the flattener.
- 1.431 - 10/3/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.37% (4th), PL: 734-11 (9th), Survival: 93.04%
- Tweaked surfing stats: lower weight to the new mid-range views, higher decay rates on recent scans.
- 1.43 - 10/2/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.33% (4th), PL: 733-12 (9th), Survival: 92.95%
- Fixed a bug in / tweaked attack angle control in surfing. (I think this may explain the strange "sit still for a while" behavior sometimes displayed at start of Melee duels.)
- Lots of changes to surfing stats.
- 1.42 - 9/30/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.44% (4th), PL: 736-7 (6th), Survival: 93.22%
- Rollback to 1.412.
- In 1v1, uses latest TripHammer gun (0.8498) in place of Main Gun. Changes to TripHammer since 1.39:
- Fixed a bug in predicting enemy next location (from Diamond 1.401).
- Instead of pulling in nearby clusters when we don't have enough data points, do KNN instead.
- Scale the "enough data" threshold up to 250 through about 10 rounds (7500 data points).
- If the cluster is very large, only use the 700 nearest neighbors from within that cluster.
- Notes: Well, this was a significant enough APS boost that I'm going to keep TripHammer as my "main gun" in 1v1 matches. Yay!
- 1.413 - 9/27/2009
- MeleeRumble ‒ APS: 69.85% (3rd), PL: 281-0 (1st), Survival: 94.74%
- RoboRumble - No 1v1 changes.
- In melee gun, instead of weighting scans by distance, weight by (bullet ticks + time since last scan).
- 1.412 - 9/27/2009
- MeleeRumble ‒ APS: 70.28% (1st), PL: 282-0 (1st), Survival: 95.13%
- RoboRumble - No 1v1 changes.
- Bullet power like 1.40 instead of like 1.392.
- 1.411 - 9/26/2009
- MeleeRumble ‒ APS: 70.05% (2nd), PL: 280-1 (2nd), Survival: 95.09%
- RoboRumble ‒ APS: 85.24% (4th), PL: 733-11 (8th), Survival: 93.17%
- Removed "light" flattener.
- 1.41 - 9/25/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.28% (4th), PL: 735-6 (8th), Survival: 93.33%
- Reverted to old style of melee wall distance.
- Melee bullet power should act exactly like 1.392 now (and via sane logic).
- Introduced a new mechanic for weighting DC scans by age:
- A DC view can have a decay rate d.
- Among the scans in the nearest neighbors clusters, the most recent scan gets full weight: <math>1 / {d^0} = 1</math>; the next most recent is weighted <math>1 / {d^1}</math>; and so on, raising d to the next power each time.
- This is modeled after the relative weights of values logged to a Visit Count Stats segment using Rolling Averages. A decay rate of 2 would be very similar to a rolling average depth of 1.
- Calculating the most similar scans is unchanged. This has nothing to do with if/how old scans are removed from the data sets - it only affects the weights of the scans being used once they're chosen.
- Surf stats updated to weight scans by age in the recent scans and flattener views.
- Added a "light" flattener that turns on at a lower threshold. Hoping to add some extra slight randomness without screwing up dodging.
- 1.402 - 9/25/2009
- MeleeRumble ‒ APS: 70.16% (1st), PL: 282-0 (1st), Survival: 94.8%
- RoboRumble - No 1v1 changes.
- New style of melee wall distance calculation in gun.
- 1.401 - 9/24/2009
- MeleeRumble ‒ APS: 70.2% (1st), PL: 282-0 (1st), Survival: 94.78%
- RoboRumble ‒ APS: 85.18% (4th), PL: 732-10 (8th), Survival: 92.93%
- Reverted surfing changes.
- Fixed a glaring bug in the gun's prediction of the enemy's next location: reversed velocity and heading parameters.
- 1.40 - 9/23/2009
- MeleeRumble ‒ APS: 70.39% (1st), PL: 281-0 (1st), Survival: 94.87%
- RoboRumble ‒ APS: 84.95% (4th), PL: 733-9 (7th), Survival: 92.65%
- Lots of changes to Wave Surfing stats.
- Slightly increased flattener thresholds.
- Hopefully final tweaks to melee bullet power for a while. Should act very much like 1.392 without any boneheaded logic.
- 1.395 - 9/22/2009
- MeleeRumble ‒ APS: 70.22% (1st), PL: 281-0 (1st), Survival: 94.75%
- RoboRumble - No 1v1 changes.
- More melee bullet power tweaks.
- 1.394 - 9/22/2009
- MeleeRumble ‒ APS: 70% (2nd), PL: 251-0 (29th), Survival: 94.55%
- RoboRumble - No 1v1 changes.
- More melee bullet power tweaks.
- 1.393 - 9/21/2009
- MeleeRumble ‒ APS: 70.03% (1st), PL: 281-2 (1st), Survival: 94.14%
- RoboRumble - No 1v1 changes.
- Lots of bullet power changes. Fixed some bullet power mistakes introduced in 1.382 (including three
<=
conditions that should've been>
=!)
- 1.392 - 9/20/2009
- MeleeRumble ‒ APS: 70.36% (1st), PL: 281-1 (2nd), Survival: 95.15%
- RoboRumble ‒ APS: 85.02% (4th), PL: 734-9 (7th), Survival: 92.79%
- Removed anti-grav dimension.
- Always wait until gun is turned.
- Speed up projections and interpolations in gun by caching sin and cos where possible.
- Adjust gun projections to use bullet flight time-1, because bullets advance an extra time before Robocode checks for collisions. (Had this detail right in data collection, but not projection.)
- If bullet power changes on firing tick, clear cached firing angles in Virtual Guns.
- 1.391 - 9/19/2009
- MeleeRumble ‒ APS: 69.06% (3rd), PL: 281-2 (1st), Survival: 93.64%
- RoboRumble - No 1v1 changes.
- One more try at an anti-grav gun dimension in melee. Slightly takes bot energy into account when calculating anti-grav force, and uses the magnitude of the resulting force in addition to the bearing.
- 1.39 - 9/18/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.2% (4th), PL: 731-11 (8th), Survival: 92.86%
- Rollback to 1.382.
- In 1v1, uses latest TripHammer gun (0.822) in place of Main Gun. Changes to TripHammer since 1.37:
- k = 250.
- When there aren't many points in the nearest cluster, add in points from one or more nearby clusters. (This was the big change.)
- In calculating kernel density, use Diamond-style if there aren't many scans to work with. This means consider the angles from the scans instead of evenly spaced angle, use a double size bandwidth, and use Gaussian kernel density.
- Notes: Looks like TripHammer is finally on par with my KNN gun in rumble performance, which is cool to see, but not by enough to keep it in Diamond.
- 1.383 - 9/17/2009
- MeleeRumble ‒ APS: 68.83% (3rd), PL: 282-1 (2nd), Survival: 93.4%
- RoboRumble - No 1v1 changes.
- Lowered weights of wall distance dimensions in melee gun.
- Notes: I thought this might be good because my melee wall distance calculation is so much less sophisticated than 1v1 wall distance. But the results so far are so poor that I may try increasing the weights instead!
- 1.382 - 9/16/2009
- MeleeRumble ‒ APS: 69.52% (3rd), PL: 280-1 (2nd), Survival: 94.01%
- RoboRumble - No 1v1 changes.
- Removed anti-grav gun dimension.
- Tweaked melee bullet power management.
- Aims gun more frequently in melee: every other tick instead of every 4th tick, last 4 ticks before firing instead of last 3 (was 3 instead of 4 because of a bug anyway).
- Removed all traces of old melee target selection code.
- 1.381 - 9/16/2009
- MeleeRumble ‒ APS: 69.17% (3rd), PL: 281-0 (1st), Survival: 93.85%
- RoboRumble - No 1v1 changes.
- Fixed the bug in the anti-grav gun dimension.
- 1.38 - 9/15/2009
- MeleeRumble ‒ APS: 68.82% (3rd), PL: 280-1 (2nd), Survival: 93.45%
- RoboRumble - No 1v1 changes.
- Attempted an anti-grav dimension in the gun. Had a stupid bug that was either giving one of the new dimensions double weight, or (I don't think it's this) totally breaking some part of the code by having [-1,1] values instead of [0,1].
- 1.372 - 9/14/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.23% (4th), PL: 732-9 (6th), Survival: 93.03%
- Switched back to Diamond's normal Main Gun.
- Notes: This should be functionally equivalent to 1.34 (in 1v1) and 1.342 (in 1v1 and melee). I just want to know for sure if I've messed anything up since then before I try to figure out why TripHammer performs so poorly in the rumble.
- 1.371 - 9/14/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.82% (4th), PL: 729-13 (8th), Survival: 92.58%
- In k-means gun, set k to 225 (from 300).
- 1.37 - 9/13/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.86% (4th), PL: 735-9 (5th), Survival: 92.59%
- Rollback to 1.342.
- In 1v1 matches, uses TripHammer (k-means clustering gun) in Virtual Guns array, instead of the usual "Main Gun".
- 1.361 - 9/11/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.39% (3rd), PL: 727-12 (9th), Survival: 93.12%
- Reverted changes to my simpler / all-purpose surfing views. (In 1.36, all but the very simplest were changed to store a max of 40 scans and use the "smart cycling". Back to storing all scans.)
- 1.36 - 9/10/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.09% (4th), PL: 731-11 (6th), Survival: 92.82%
- Rollback to 1.342.
- Lots of additions and changes to Wave Surfing views, especially recent and flattener scans.
- Using "remove closest to new point" instead of "remove oldest" for all surfing views that cycle out old points (internally, I call this "smart cycle"). Anti-Surfer gun still using normal cycling.
- 1.351 - 9/10/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.93% (4th), PL: 731-13 (6th), Survival: 92.54%
- Tweaks to 1v1 wall avoidance: only look 4 ticks ahead; much tighter bound to wall considered a "wall hit" in predictions.
- 1.35 - 9/9/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.4% (3rd), PL: 729-10 (8th), Survival: 93.11%
- Added wall avoidance to Wave Surfing (to augment existing Wall Smoothing), so it should just about never hit walls any more.
- 1.342DL - 9/9/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.3% (3rd), PL: 731-9 (6th), Survival: 92.86%
- Gun from Dookious 1.573c.
- Notes: Wow, Diamond's gun is stronger than Dooki's!
- 1.342 - 9/9/2009
- MeleeRumble ‒ APS: 69.44% (2nd), PL: 278-0 (2nd), Survival: 93.9%
- RoboRumble - No 1v1 changes (from 1.34).
- Revert bullet power changes.
- 1.341 - 9/8/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.2% (4th), PL: 731-8 (6th), Survival: 92.79%
- Anti-Surfer gun only collects data during 1v1 scenarios.
- Fixed bug in melee gun introduced by 1.34 refactoring. (This was the actual cause of the melee skipped turns for 1.34.)
- Misc tweaks to debugging graphics, mostly in gun.
- When Virtual Guns ratings are high (1v1 only), fire higher power bullets.
- 1.34 - 9/7/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 85.40% (3rd), PL: 735-6 (5th), Survival: 93.02%
- Rollback to 1.33.
- Added an Anti-Surfer gun (and Virtual Guns system).
- Fixed a bug in the gun's wave collection affecting close range situations.
- Notes: Skipping turns late in melee matches. I'll probably remove data collection for the Anti-Surfer gun except in 1v1.
- 1.332 - 9/1/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.89% (4th), PL: 722-15 (12th), Survival: 92.66%
- Added yet more views to Wave Surfing, tweaked some hit percentage thresholds.
- Notes: It's remarkable how much the multiple views of 1.33 helped, yet how precisely similar 1.33/1.331/1.332 are with adding/tweaking the views further.
- 1.331 - 9/1/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.85% (4th), PL: 724-14 (8th), Survival: 92.54%
- Added a couple more views to Wave Surfing.
- 1.33 - 8/31/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.9% (4th), PL: 719-18 (15th), Survival: 92.6%
- Created a more robust system for handling multiple "views" of Wave Surfing stats. Converted and tweaked old (hard-coded) views to new system and added several more.
- 1.323 - 8/30/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.29% (5th), PL: 718-21 (17th), Survival: 92.06%
- Rollback to 1.32.
- Fixed a bug in Wave Surfing danger calculation: when weighting scans by inverse scan distance, forgot to pass the weights, so was using unweighted distance.
- 1.322 - 8/30/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.12% (6th), PL: 720-19 (16th), Survival: 91.83%
- Changes to Wave Surfing:
- When enemy hit percentage is above the threshold for which we add in recent scans, ignore all scans' distances from (i.e., similarity to) the current scan when calculating danger.
- Remove duplicates between "all scans" and "recent scans" clusters (as in 1.274/1.275).
- 1.321 - 8/30/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.39% (4th), PL: 719-21 (17th), Survival: 92.16%
- In Wave Surfing, lowered hit percentage threshold for adding in extra recent scans.
- 1.32 - 8/29/2009
- MeleeRumble - Not entered.
- RoboRumble ‒ APS: 84.4% (4th), PL: 723-17 (13th), Survival: 92.22%
- Tweaks to Wave Surfing attributes:
- Against non-simple targeters, drop lateral velocity, add velocity and relative heading.
- For relative heading, split into two values: lateral (sin) and advancing (cos) components.
- Tweak all the weights.
- Slightly more danger associated with moving closer to enemy.
- 1.31 - 8/28/2009
- MeleeRumble ‒ APS: 69.09% (2nd), PL: 275-1 (2nd), Survival: 93.84%
- RoboRumble ‒ APS: 84.51% (4th), PL: 721-15 (12th), Survival: 92.4%
- 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.

- 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 - APS: 84.4% (6th), PL: 716-12 (16th), Glicko-2: 2121.1, Survival: 92.03%
- Movement:
- Surf remaining waves in the air after enemy dies.
- 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.
- Actually fixed the gun wave management issues found in 1.20*. (Mainly impacts melee.)
- A few miscellaneous tweaks and bug fixes in melee gun function.
- 1.202 - 7/18/2009
- MeleeRumble - Not entered.
- RoboRumble - APS: 84.09% (7th), PL: 713-16, Glicko-2: 2115.5, Survival: 91.78%

- 1.201 - 7/18/2009
- MeleeRumble - Not entered.
- RoboRumble - Pulled

- MeleeRumble - APS: 65.40% (7th), PL: 263-4, Glicko-2: 1734.8, Survival: 87.43
- 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.)

- 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.

- Fixed a bug where Diamond might shoot himself disabled.
- Fixed a bug in the current heading / random direction changing code.
- Enhanced Wave Surfing debugging graphics, including drawing color-coded dangers along two closest waves.
- Only executes graphical debugging code if painting is enabled. (This also fixed the buffer-overflow I was hitting when enabling paint mid-match.)

- 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.)
- Added a mechanic for factoring in similar scans from recent rounds in addition to similar scans from the whole match.
