Repeated Battles

Not sure if this is the best place to put this, but here it is. My roborumble client would keep getting hung up running the same bot over & over, regardless of how many battles it already had or how many other bots were below the BATTLES_PER_BOT limit I set. I think I took care of the problem by deleting files between between runs of the rumble. This is my roborumble.bat file now:

java -Xmx256M -cp libs/robocode.jar;libs/codesize.jar;libs/roborumble.jar roborumble.RoboRumbleAtHome ./roborumble/roborumble.txt
del roborumble\temp\battles*
del roborumble\temp\priority*

I think the priority battles file was the culprit, but I'm leaving the other line in for good measure. --Simonton 16:35, 22 September 2008 (UTC)

Woah, I certainly see the results of these stuck pairings... such as Drifter vs Okami over 200 times, and similar for Fermat vs Okami. It sure feels unusual seeing over 100 battles in any pairing in RR, but at least we know those pairings are accurate haha. --Rednaxela 19:22, 22 September 2008 (UTC)

As for accuracy, below is the impact of battles on the score. This is 0.7*old + 0.3*new. For first battle you can also read 'all battles till now'. This means that 2 new battles will reduce the influence of the previous ones to 50%.

         1   2   3   4   5
first   100
second   70  30
third    49  21  30
fourth   35  14  21  30
fifth    25  10  14  21  30

Sorry, Grub, I'm not really following you. What does this table represent? What is its relevance to rumble scores? --Simonton 23:57, 22 September 2008 (UTC)

It's the influence of each battle on the % score. From the table, after a bot has 5 battles in a pairing, the most recent battle has a weightage of 30%, 2nd most recent 21%, third is 14%, fourth is 10% and the first battle ever run for that pairing is 25% (the first battle always has a disproportionate weighting) towards the % score for that pairing -- KetsuNfwu 08:48, 23 September 2008 (UTC)

Security exception 1.6.0

One bot suffers from a security exception in v1.6.0, namely axebots.SilverSurfer. It seems the only bot that has this problem, so the impact is not that big. Maybe someone (or Axe himself) can update the bot so it can be processed by the latest robocode versions. --GrubbmGait 23:52, 22 September 2008 (UTC)
