The most straightforward algo is probably to continiously mine the oldest challenge until the latest_submission and then move on to the next oldest. This requires keeping a full history/cache of challenges somewhere but is guarenteed to mine the easiest challenges for longest (assuming challenges go up in difficulty).
The NuFi wallet seems to have an API for getting all the challenge info, but might not be a good idea to rely on it as they could close it off if they see lots of traffic not originating from their wallet infra.

I did wonder about this a day or so ago. I guess the ideal sorting mechanism would be to mine the easiest challenge in the queue, which would keep weaker machines productive for longer. I'm not sure what the trade off for that is though. Do we know if the end of the mine just stops distributing challenges or it stops accepting submissions as well?

[joncrocks]

If the challenges simply go up in difficulty, then the earliest released challenge will always be the easiest (or tied). It's not clear whether the last challenge will still have 24 hours to solve or if the latest submission will become a hard cut off as we approach the end.

I suspect the last 24 hours being 'browser only' might mean they reduce the difficulty back down.

Also wanted to add @SL13PNIR - thanks for all your hard work, I appreciate everything you've done here. If you want a second pair of eyes on the underlying code/code reviews, just let me know. (Although only really free UK evenings/weekends, I think I sleep more than you, heh)

Left my 0.3.3 running all day, just got home. Unfortunately it's running the first new difficulty, not the easiest.

@SL13PNIR - Any chance of a hot-fix with the last easiest?

Are you sure it's not just the dev address that's mining the current challenge?

I don't think I have time to patch this. Be aware there's only ~1 day left of API mining.

[joncrocks]

Yeah, I'm fairly sure. It appears that the miner started up and mined every address with the first encountered challenge. Then when cyclying back to address 0 it switched the 'latest' one.

I'm not sure the 'easiest challenge' code ever worked as intended. It hasn't helped the last two times the difficulty has increased.

But that doesn't detract from your efforts, I've scavenged more than I would have through the web UI. Many thanks!!
