Not a satisfying puzzle; brute force try all fixes seems to be the only
solution.

That was how I felt, too: brute force. I looked at it a while to find a better way.
If you didn't like that, I regrettably have some bad news about Day 9's puzzle.

Day 10 allows for a non-brute force solution, and this is worth the effort.

Do you consider my solution for Day 9 as brute force one? ;)

I really like this approach, but it seems equivalent. I wondered if I misunderstood the approach, so I worked it out the example problem by hand both ways, and both perform roughly the same number of "additions": 11 for the first, 14 for the second. So unless I've misunderstood something (and the example may be a bad one) this also seems brute force.
(Thanks for pointing out the error in my code, by the way. Judging by my comments, I misread the directions.)

Regarding part 2, you are probably dead before a brute-force solution finishes...

Yes. Now on do day 10.
