Wow, how did you find [[Stormrider]]? It's been out of action for ages.... If you want a version that is slightly newer, and much stronger, take a look at DrussGT, it's download link is on the RoboRumble/Participants page. Anyways, welcome to the wiki, and good luck with your coding =) If you have any questions feel free to ask. -- [[Skilgannon]]

Hehehe [[Stormrider]] was on the new wiki in the [[Bots]] section, and it said it was very competitive so I downloaded it. I was really new to everything at the moment, now I'm more settled, I'm running RoboRumble so I have [[DrussGT]], BTW congrats man, it seems to be very comfortable at the top place :). Thanks for the help and for killing my bot so I'd be interested in learning more. -- [[zyx]]

I'm trying to learn how to use the wiki, so probably will be asking more questions. But to start I would like to know how to add those nice ''content tables'' to the pages, I've been going trough the pages that has them and see nothing special in the code :-S. And as a more general second question, is there somewhere I can learn how to write wiki stuff? Particularly this one of course. --[[User:Zyx|zyx]] 01:11, 7 May 2009 (UTC)

[[wikipedia:How_to_edit|Here]] is all about mediawiki syntax. MediaWiki automatically add the TOC once the page have more than 4 headers (inclusive) at before the first header. If you want to add the TOC manually, add <nowiki>__TOC__</nowiki> to the page (like this page) &raquo; <span style="font-size:0.9em;color:darkgreen;">[[User:Nat|Nat]] | [[User_talk:Nat|Talk]]</span> &raquo; 01:22, 7 May 2009 (UTC)

Another useful link I bookmarked recently is [http://meta.wikimedia.org/wiki/Cheatsheet this MediaWiki cheatsheet]. I tend to check [http://mediawiki.org mediawiki.org], or just Google (eg, ''mediawiki namespaces'') when I'm looking for something specific. There's a lot of good info out there because so many people use MediaWiki. But I've learned a lot of what I know from people like Nat and [[User:AaronR|AaronR]] doing stuff on this wiki. =) --[[User:Voidious|Voidious]] 01:30, 7 May 2009 (UTC)

:I've still got a few tricks up my sleeve, I just haven't had time to implement them. Involving both guns and movement. And new types of stats. But come on, I'm studying Mechanical Engineering and you're doing Computer Engineering, surely you should have passed me ages ago? ;-) And I've been hearing that you were working on RougeDC's replacement in little snippets here and there, are you ever going to release that to the rumble? -- [[Skilgannon]]

Thanks guys, I'm too dinosaur-ish for web related stuff. This is the first wiki I've been, and have been moderator of two forums, but there I'm just as dumb as I am here :-P. --[[User:Zyx|zyx]] 01:56, 7 May 2009 (UTC)

I always realized that your handle was the last 3 letters in the alphabet, but it only just occurred to me that this is like the opposite of "[[User:ABC|ABC]]". I'm curious if that is intentional or just coincidence? (To be clear, I mean if it's inspired by ABC the Robocoder or not.) Kind of funny that two of our PL kings have such similar handles. =) --[[User:Voidious|Voidious]] 18:16, 4 August 2009 (UTC)

I just realized there are ways to shoot completely undetected bullets, I tried to make a bot based on that but I can't find an easy way to use the exploit and be competitive at the same time. So I decided to just post how to fire undetectable bullets, I haven't really searched, so maybe this has been said elsewhere.

I think most surfers have some way to detect (as good as they can) when their enemy hits a wall so they are not confused by that energy drop. So if you run towards a wall at some speed, let's say full speed (8), and when you are just about to hit the wall you decelerate and a fire a 1 power bullet. Your enemy will calculate your damage as 8 / 2 - 1 = 3, but you were actually going at 6 at the hit time, so you got 6 / 2 - 1 = 2 wall hit damage, but since you shot a 1 powered bullet they won't see anything strange as your energy dropped 3. And even if someone has thought of that, and took the guess that maybe the bot decelerated you can shoot only sometimes, and make him surf bogus waves.
+
== Melee Testing ==
 +
How do you guys test melee bots? Not tool-wise, I know [[Voidious]] patched [[RoboResearch]] which I will probably use to test the melee bot as well soon. But I mean battle-wise, I was testing with the top 6 bots from different authors and 2 ''random'' middle bots, the other two spots were taken by two versions of my bots and ran 100 round battles and compare the results of my two bots to decide which one is better. But I knew that testing wasn't suitable, YersiniaPestis 3.0 can beat [[Shadow]], [[Aleph]] a lot of times (~40% of times beats one of them), [[Portia]] every now and then and [[Fermat]] every time under that circumstances, but I knew that in reality battles don't such a high concentration of top bots so results were kind of irrelevant as rumble performance meant. Thanks. --[[User:Zyx|zyx]] 21:03, 19 August 2009 (UTC)

This bot shows how to shoot the invisible bullets, it bounces on and off from the top wall (sometimes the bottom) and shoots head on, so it will lose to almost every(if not all) bots. But I challenge anyone to try and detect accurately when he fires. My bots detect some of them, but is not even close to accurate.
+
: Well, I struggle with this too, but my attitude is to try to emulate the same mixes of bots that you'll face in the rumble. So you'd want the same range of skill levels, some battles with all weak bots, some with mid-range bots, and some with stronger bots. Right now my test bed is 27 bots, split into 6 groups (with each bot appearing twice), and I'll run ~20 seasons. For many versions of [[Diamond]] in a row, this was accurately predicting a rating increase or not. Then I released a version without much testing, its rumble rating went up, but I ran the test afterward and the score went down. :-/ So I'm still figuring it out myself, really. If you're curious about my test bed, it's here: [http://www.dijitari.com/void/robocode/dibed6.rrc dibed6.rrc]. Good luck, and please let us know if you make any Melee test bed breakthroughs. =) --[[User:Voidious|Voidious]] 21:30, 19 August 2009 (UTC)

I don't know if any of you like programming contests, but I'm actually a devoted contestant of those.

Haha, perfectly accurate detection is impossible. It has been discussed [http://robowiki.net/cgi-bin/robowiki?EnergyDrop here] (see some of ABCs notes) why one can at best guess the wall damage with an error between +0.5 and -1.0. The only possible real countermeasures I believe are: 1) Fire low-weight waves whenever the enemy hits the wall or 2) Detect if you got hit by a wallhit-concealed bullet, and if so presume they always make wallhit-concealed hits so long as gunheat indicates that they could have. A truely accurate countermeasure? That's impossible. --[[User:Rednaxela|Rednaxela]] 07:25, 18 March 2009 (UTC)

My mom is currently visiting my brother in the UK, I always buy some books when she is over there since I love reading scientific or technical books. Currently I'm looking to expand my AI books collection since it is rather poor, and I thought maybe some of you could help me find a good choice. I already have ''Artificial Intelligence: A Modern Approach'' of Norvig and Russell, although it's the first edition and in Spanish so I'm considering the second edition in English. But besides that one which good AI books can you recommend? Also I have a couple of NN books so I would be more interested in something either general or specific to other subjects, but if you have a good NN book to recommend I wouldn't mind hearing and reading about it as well. Thanks in advance. --[[User:Zyx|zyx]] 01:16, 7 September 2009 (UTC)

Thanks for all your responses, I won't buy the books recommended by [[Darkcanuck]] (the first one) and [[Voidious]] because I can download them and I have to save every penny, in Venezuela we have exchange control right now and we are only allowed to spend $400 on Internet each year :-S. The NN book, well I have some and as he said ai-junkie is a great place. The book [[Positive]] posted is really inexpensive so I was excited at first, but I read a bit on the Amazon preview and it seems fine but rather basic, I already have 3 undergraduate AI courses and I'm actually looking to do some graduate level studies now.

I will buy the second edition of ''A Modern Approach'' of Norvig and Russell as it seems to be the most recommended book all around the world, to have it as a reference rather than reading it in depth again. And just to please my self I will buy the first 2 books from the ''AI Game Programming Wisdom'' series, they seems to be in the same fashion as the Game Programming Gems series which I found to be amazingly interesting when I first read them. Thanks all, and I hope you get something out it as well. My mom comes back next week, I'll let you know then how good or bad the books end up being. --[[User:Zyx|zyx]] 21:36, 7 September 2009 (UTC)

Wiki Help

I'm trying to learn how to use the wiki, so probably will be asking more questions. But to start I would like to know how to add those nice content tables to the pages, I've been going trough the pages that has them and see nothing special in the code :-S. And as a more general second question, is there somewhere I can learn how to write wiki stuff? Particularly this one of course. --zyx 01:11, 7 May 2009 (UTC)

This is probably very late, I received the email like a week ago (around May 4th or 5th), but I saw your prize is marked as dispatching, so I guess you received it too. Sorry for the late reply, been too busy to check robo wiki. --zyx 20:58, 10 May 2011 (UTC)
