I'd be interested to see what the best values people can find are. My best solutions so far are 40 and 149.

It's consoling for me that there are not many solvers until 11/09. I have no code producing a complete solution, but only codes optimizing versions found with pencil and paper.

Yeah, I think this is one of the toughest puzzles there has been recently.
I slightly improved the bonus solution to 147, but I'm still on 40 for the first part.

I'm blocked at 54 damage. Normal pencil and paper cannot give a solution easily.
I only want to abandoned. So Difficult question!! [8976 "," 4238 "," 8297 "," 4735 "," 3279 "] 31415926535897932384626433832795028841971693993751058209749445923078164 327947358976423847354238327932798976829747358297473547538976 54 damage. This solution does not spoil the challenge, it's blocked at 54.We have to start at the beginning, if we want another winning solution. But it can help!

Remember you can use hyphens in both strings.
I'm impressed people managed to get solutions that good with pen and paper, I didn't even try that approach because I thought it would be too hard.

But there, I'am obliged to get help with the calculation. There are 1680 possible permutations from 2 to 9 for each quadruplet. I leave the 0's and 1's, they don't do a lot of damage. Congrats, for this impressed solution 40 and 147.

Well seen this Permutation typing error without consequences for the damage. Thanks Dieter! Question: Can we find less than 54 damage without any pulling on the sequance pi? ** Congrats Dieter, for solving with the manual "to tear out"! Last fiddled with by Kebbaj on 20210914 at 10:07
