What's special about it?

It is a twin especially (and only working) for the TwinDuel Tournament.

Great, I want to try it. Where can I download it?

see http://www.dijitari.com/void/robocode/twinduel_20070301/

How competitive is it?

It wins as much as it looses, so its in the middle

How does it move?

Double oscillator with the urge to fight close.

How does it fire?

Iterative circular gun, like 90% of my bots. It will fire at the closest with a slight preference for the enemy teamleader and weak prey.

How does it dodge bullets?

It doesn't.

Does it have a specific TwinDuel strategy?

Although the bots focus their radar on different opponents, their movement is focussed on the enemy teamleader. Therefor it will close in on and try to corner the teamleader. Alas some friendly fire is unavoidable during the close in, as TheOther will not notice FirstBorn in its firing-line.
Same strategy goes when one or more bots are killed (2-1, 1-2, 1-1). The only difference is that the radar will become a melee-radar when fighting against a majority.

What does it save between rounds and matches?

nothing.

Where did you get the name?

It is a sort of growling to frighten the opponents and it starts with 'Gr' like all my bots. As they are an identical twin their name is a palindrome.

Can I use your code?

It's in the .jar, released under the RWPCL.

What's next for your robot?

A GF-gun would be nice, as now it is beaten by almost all learning guns.
Probably some tweaks to the (close-range) movement.

Does it have any WhiteWhales?

Every other twin that beats it will become one, but CoyotePair is the most likely first candidate.

What other robot(s) is it based on?

It is based on Gruwel together with some GrubbmGroup.

  • much more agressive distancing (close range)
  • bugfix startup enemy recognition
• 0.3 - 20070221 (wins 4 - 10 losses)
  • fixing radar- and move-Target selection
  • back to Gruwel-like oscillator
• 0.2 - 20061102 (wins 1 - 13 losses)
  • added communication
  • radarlock on different targets (including bug)
  • lousy movement
  • not very good strategies
• 0.1 - 20060817 (wins 5 - 5 losses)
  • basically GruwelTwins with a preference for close-range and a small gun-tweak

Comments, questions, feedback:

I am now busy with a GF-gun for GrauwuarG, but it performs similar to the existing CircularTargeting GrauwuarG 0.32. The gun is taken from Grinnik with the addition of segmenting on heading to make use of the fact that opponents are driven into a corner. I expected a bit more performance than 7 wins, 7 losses and a percentage of 52%. Maybe I will put in the gun of Komarious (is RaikoMicro) as a test to see under what circumstances I do something wrong, as I cannot find any bug yet. -- GrubbmGait

Yeah, I've had a lot of trouble really finding success with improved targeting in the TwinDuel. I tend to think you want lower segmentation than Raiko / Komarious, since you have a lot less data; but it is also a longer match, I guess. Consider how well Shiz does with just HeadOnTargeting. Somehow, I still feel better having a GF gun in there... -- Voidious

I have fitted in the gun of KomariousTeam and it scores 8-6 with 52% . . . . doesn't that sound familiar? This means that my movement is the weak point and nothing else. As one of the few teams with a real team-strategy (even if it is a simple one) I don't want to overhaul it completely, but it is clear that the movement has to be adapted to the close-range strategy. And as the movement is basically the same as Grinnik, Gruwel and GrubbmGrb, I may win some points there too. -- GrubbmGrb
