Very nice job man. I don't know if there are differences on the 1v1 code of versions 1.0 and 1.13, if there are you should enter version 1.13 in the 1v1 competition to compare it to Shadow, maybe there is a chance to boost Portia by turning seconds to firsts? Although [http://darkcanuck.net/rumble/BattleDetails?game=meleerumble&name=positive.Portia%201.13&vs=abc.Shadow%203.84 comparing them], would make me think that you should be improving you gun, check the bullet damage difference between them. Good luck, and congrats again. --[[User:Zyx|zyx]] 17:18, 11 August 2009 (UTC)

How many call to sin & cos do you do each tick? If it is below 10,000, that isn't a reason, or you think it is slow while in fact it isn't. Oh I see... you have a lot of small classes, which is obfuscated I think (no one name the class a,aa,ab,...) » Nat | Talk » 10:15, 12 July 2009 (UTC)

Hey Nat, I've tested it, and its speed is about half the speed of Shadow. I believe I'm using about 700 trigonometry functions and 200 sqrts each tick, depending on the situation. If that's not it, I'm not sure what is. Maybe its the simulated bullets, I'll have a look for a next version. I've speed and size optimized the .jar, that's why you see the "a,aa,ab,...". --Positive 18:23, 12 July 2009 (UTC)
Just curious, what program are you using for the speed and size optimizations? I'd be interested in trying it on DrussGT to see if it solves my skipped turn problems =) Also, one way to speed up your bot quite a bit is to only aim your gun for the 4 ticks before you fire, and the rest of the time just point your gun straight at the enemy's location. --Skilgannon 21:23, 12 July 2009 (UTC)
I used ProGuard 4.3 for the optimization. Tell me what it does for Druss. :) Just aiming your gun for the opponent is a good idea, and Portia already does it. :) 22:11, 12 July 2009 (UTC)
I just noticed, Portia doesn't do it for the solo gun. Adding it now. :) --Positive 21:54, 16 July 2009 (UTC)

By the way, I'd like to hear your opinion about Portia (if you've played with him). I think the meleemovement is quite different from most bots, and it seems to be doing great (6th in the meleerumble at the moment). --Positive 22:11, 12 July 2009 (UTC)

Congrats on a really awesome debut, dude! The rating will still fluctuate quite a bit until you hit full pairings and ~2,000 battles, but I bet it stays at 5th or 6th. I've been easing back into work on Diamond -- now I'm even more motivated. ;) --Voidious 22:36, 12 July 2009 (UTC)

Thank you. :) I'm glad my bot poses a new challenge to you. :P For the solo part, I've already spent many hours trying to defeat Dookious as well. Not very successfull though, at least not after he activates that damn flattener. ;)

Hi there, welcome to Robocode. Thanks for making me run some melee battles again, great movement you got there, congrats. I'm even thinking about making my own melee bullet detector now... --ABC 23:47, 13 July 2009 (UTC)

ABC, are you checking the wiki all the time and make no comment? PS. Sorry if I get Portuguese wrong, result from Google Translate » Nat | Talk » 12:44, 14 July 2009 (UTC)
Not all the time, but I still check the wiki and the RR server frequently. My life has been a bit too busy to participate actively, though. Your Portuguese was correct, and I didn't forget the email you sent me, btw. :) --ABC 14:28, 14 July 2009 (UTC)
Thank you. :) --Positive 19:43, 14 July 2009 (UTC)

DC Pattern Matching or DC Play-it Forward? If it is really DC-PM, I'm really interested on how it works. » Nat | Talk » 13:11, 3 August 2009 (UTC)

What's the difference? --Positive 13:27, 3 August 2009 (UTC)
Well, I'm guessing you just mean a DC / "Tron's Gun" style gun, which used to be called a "forward pattern matcher" and was once generally considered PM. But the consensus is that it really isn't pattern matching at all, so I think Nat is wondering if you're doing some new type of DC gun that also uses pattern matching. --Voidious 13:30, 3 August 2009 (UTC)
Yes, I based the gun on TronsGun page. So I guess that makes it a forward pattern matcher. Portia 1.12 makes a "pattern" based on the opponents: displacement vectors for roughly the last 30 ticks, current velocity, acceleration, and other variables like distance to wall. It then stores that "pattern" 100 turns later in the KD-tree, with a reference to the turn it was recorded, if the opponent is still alive. :) --Positive 13:53, 3 August 2009 (UTC)
What do you do with those 30 displacement vectors? Do you have like 35 dimensions in your tree, or is it something else? Great job with the new gun, looks like you might snag 3rd (knock on wood). --Voidious 14:12, 3 August 2009 (UTC)
Thanks (quickly knocks on wood as well)! :) It calculates 3 displacement vectors over those 30 turns, and takes 1 heading difference and 3 displacements from them for dimensions. I don't think 35 dimensions would be very managable. :P --Positive 14:41, 3 August 2009 (UTC)
Wow, really amazing! Huge congrats on 3rd place with 1.12 - and closing in on Aleph! --Voidious 00:44, 4 August 2009 (UTC)
Thankyou. I didn't dare hope such a jump. :) It's pretty exciting how much you can do, and is still possible in melee. :) --Positive 11:04, 4 August 2009 (UTC)

You really are amazing me - congrats on overtaking Aleph for the #2 spot! If I were ABC, I might start getting a little scared. =) But Shadow still has a pretty incredible lead (3.83 was about 1% APS higher than 3.84) ... for now. Best of luck in your quest for the throne! Hope to catch up sometime. --Voidious 16:55, 11 August 2009 (UTC)

Big congrats from me too, great work. Don't stop now, you are going places! ;) --ABC 17:04, 11 August 2009 (UTC)
