DemonicRagev3.07

- tuned gun, added 1vrs1 flattener(rarely on, if ever) reduced health wieght, and territory wieghts, (which I should look at again for further improvement). fixed bug in bin smoothener and redesigned and tuned. Currently in number 2 spot with 414 battles :) Hope it holds on :) Just in time as I'll be back in school soon.-Jlm0924 19:50, 29 April 2010 (UTC)

Cool, fingers crossed dude! --Voidious 19:44, 29 April 2010 (UTC)
I'll cross'em for third :)-Jlm0924 19:50, 29 April 2010 (UTC)
Very nice! I guess this means I'll need to get working on Glacier... (given how terrible it's movement is in 1v1, perhaps I should just throw a quick random movement in to get an instant boost...) --Rednaxela 21:34, 29 April 2010 (UTC)
You should .. Your kick-butt gun is probably begging for it :) .. I'm waiting for 3.07 gets 1500 battles or so before releasing 3.08 ;) -Jlm0924 23:52, 29 April 2010 (UTC)

DemonicRagev3.05

despite finding a small bug in DR3.03 1vr1 movement, It's still performing sub par. I will need some time to improve DR's 1vr1 waveSurfing ( i've never spent much time there before.) Till then; I slapped the old random 1vrs1 movement back in to see what happens in the rumble. —Preceding unsigned comment added by Jlm0924 (talkcontribs)
Well, personally, I'd put one HawkOnFire vs DR3 in 1v1, and attempt to fix the remaining times DR gets hit since HOF is just a "Head-On" targeter. In some tests I saw it dodge well enough that it's clearly surfing, however got hit often enough to indicate the surfing is flawed in some manner or another. --Rednaxela 23:52, 25 April 2010 (UTC)

yeah the bug in 1vrs1 : DR3.03 was accidently not just surfing the closest wave.. (It might have choosen a high risk part of the closest wave if that position was low risk on the waves behind it.) Without that flaw (unsegemented) works great for the first 10 rounds or so. Then the big guns start gaining ground back.. I tried simple segmenting, but it learns too slow to compete with the better Guns. I know nothing about the more advanced wavesurfers.( Whats going on in Druss/Diamond or Glacier?) ..but I'm going to avoid the segment setup, and try surfing with DC. `Jlm0924 06:42, 26 April 2010 (UTC)

Well, Glacier isn't a surfer (in fact, it's 1v1 movement is terrible, just see it's non-melee ranking). Well, how to set up learning for surfing is basically the same as building a gun. I'm sure DC will work better than a single segmentation, though some like Druss have success with overlaying multiple segmentations. One note is usually one segments surfing less heavily due to the reduced amount of data. The other note, is that the particularly good guns start gaining back ground, even with segmented/DC surfing really, and what is usually done to counter this is enable a "flattener" when the enemy hit rate is high enough. The "flattener" basically keeps stats of where you've been, instead of where you've been hit, and you dodge that as well. This works well because it avoids going to the same place twice even if you haven't been hit there yet. Note though, a flattener isn't really necessary. Midboss and RougeDC in 1v1, both lack a "flattener" yet still score high (though not so high against the strong bots due to the lack of such). One thought, is because melee gives much less time to learn than 1v1, perhaps it would make sense switch to pure-flattener against the final remaining bot? I say such because I think chances are the final remaining bot is strong enough that flattener could be best. --Rednaxela 13:33, 26 April 2010 (UTC)

From Portia's stats that was posted sometimes ago (I can't remember where), there is only a few bullets that actually fell into your escape angle and actually hit (the one you can save stats), so your should combine it with your old MR movement to be competitive. My two cents anyway. --Nat Pavasant 14:00, 26 April 2010 (UTC)

Thx for your wisdom Rednexala. DR has a flattener. But it worked better always off, then alway on :) so I will try enabling it as you suggest. When I get Home, I will release DRv3.06 with (NO-SEG, NO1vr1 bugg, and properly activated flattener) into the (Non-Melee) Rumble for the first time..and go from there. :)-Jlm0924 00:35, 27 April 2010 (UTC)

DemonicRagev3.06

VR3.06 released.. ( still no segment, removed small 1vr1 bug and found bigger melee stats bug, played with the flattener (the stats to enable it were swayed by melee/ so I disabled for now) I also removed 2 gun distancing functions (distance and angle) and enabled painting waves. I've come to realise there is alot I can improve still. Currently Dr is selective on which waves it 'sees'. TODO list : allow DR to see more waves and weight them. Precise escape angle. -Jlm0924 00:35, 27 April 2010 (UTC)

DemonicRagev3.0

Lately I have completely rebuilt and improved Demonics foundation (still based on Module) I implemented Rednaxela's tree into a bare bones version of D's gun, which I plan to later expand after the new movement is fleshed out. The gun's new PIF I made should be quite quick. I'm not sure how it compares to displacement vectors or if it's type has been done before, but I will post it and D's Radar source code next chance I have.
I released DR3.0 early. I just got the melee movement working and the gun is untuned. 1vrs1 is temperarily random. I should of disabled some painting and tested for skipping turns, but it seems fine. -Jlm0924 17:11, 20 April 2010 (UTC)


Source Code

I left it as is, with code commented out in case someOne wants to play with it..
I have updated the Radar code to be more Inclusive and Robust -Jlm0924 18:33, 28 April 2010 (UTC)

Comments

Very nice! Seems you've won the race to melee surfing? (EDIT: To melee surfing that collects stats I meant. Since apparently Shadow does do non-learning wave surfing in melee, and while I believe Portia learns a little about enemy targeting it's not technically a wave surfer) I'm a little surprised by DemonicRage still performing behind Glacier though. Perhaps do some 1v1 tests of the surfing to see how well it's working in a more basic situation? --Rednaxela 15:16, 23 April 2010 (UTC)

Thanks, your right... I haven't really tested the 1vrs1. The only difference between the melee and 1vrs1 is seperate Stats, which are both non-Segmented. I haven't tried segmenting yet, but I'm sure the 1vrs1 needs it. -Jlm0924 17:35, 23 April 2010 (UTC)
