When bots try to solve puzzles:
Is ‘timed out’ different from failed? If so, why/how?
I’m wondering the same thing. 
hi blubblub, starryjess,
It’s really a subtle difference.
“Timeout” means, it didn’t really get stuck, but it was taking too much to solve the puzzle. We are limiting computer’s puzzle solving time to one hour, and if it goes beyond that we say it timed out.
Failed, means the algorithm just got stuck in a puzzle and has declared it can’t solve the puzzle.
I hope this clears out the confusion
