Is there a mistake in Rumble battle staging

Jump to navigation Jump to search

as far as I can remember, some time ago (~1 year) there was a hickup which resulted in the strange rumblerankings. Bots had disappeared from the ranking, and when they came back after a battle, their stats against others was either complete or just 1 battle. Just can't find evidence of it on the wiki

The pairings are already missing in 2021, so it mustn't be resulted from the 2022 hickup http://web.archive.org/web/20210127174934/http://literumble.appspot.com/BotDetails?game=roborumble&name=voidious.micro.Jen%201.11

A strange thing is that most pairings wit 1 battle (of nz.jdc.nano.NeophytePattern 1.1) are either 2020.10 or 2022.3 (which is the exact time the last hiccup happened). This may indicate that the loss of pairings are resulted from restoration process.

Would it mean that there is a lingering database which has old pairing number? I.e. literumble thinks that there are plenty of pairing (thus not asking for more battles) but it shows in the stats only actual ones.

No, you can clearly see from the code that all data is saved into bot.PairingsList, which gets overridden each time a new battle is ran. So if a pairing is missing, the data may not be lost, but if a pairing shows 1 battle, then that's all LiteRumble has.

Skilgannon once said that he had backups. We could ask help from him and do a merge, e.g. take whatever pairing with max battle counter.

Then it must be a bug in the pairing selection algorithm which some how avoid certain bots. Do we have old data or not is irrelevant, if bot has low pairing that it should be scheduled for a battle, which does not happen with the old bots.

Currently if you put a new bot in the rumble, it usually fighting non stop for at least for a several thousand battles with different opponents. So at same point it would have more battles then old ones like Jen.

For example, the bot which I put a couple day ago http://literumble.appspot.com/BotDetails?game=roborumble&name=eem.zapper%20v4.44&order=-Battles already has at least 9 battles with everyone. So I would think Jen or nz.jdc.nano.NeophytePattern would be already scheduled to fight some one for the 2nd battle, but this does not happen.

I see now. I was not aware of 5000 threshold and priority for a newer bot. Thanks for the explanation.
