Woah it's nice to see all the puzzlers' solutions for the optimizers!
About the equation, the first three are not valid: "_PLUS_65821=-9403x-7" and "65821=-9403x-7" use two consecutive operators, which is not allowed (based on an answer on this thread). Maybe you will cap these solutions to the optimal one (with score 658210), since this issue was not clarified in the Puzzle Booklet and was fixed only the last day of competition.
Huge thanks for all these beautiful puzzles, some classic ones were really hard and very enjoyable to solve!

Thanks Paul,
I have completed the check and you will see the preliminary results very soon.

Yes, THANK YOU RIAD for some really great puzzles. I love the format, much more satisfying than 60/90 minute frenzy with the printer
On first seeing them, I thought I would hate the optimizations, but in the end I loved them all. It turns out the only thing I really hate is Mechanical Sudoku. The number equation was the least fun of the optimization - mostly because I resolved to manual brute force,. I am happy to see that I managed "local optimums" for Record Score (best solution with symmetrical paths), and Opti-Road (best solution with G=g (or V=v).
As for the top three solutions for "From 0 To 9":
Since these solvers were aware of the possibility to use negation/unary minus, which was explicitly endorsed by Riad on the forum, I would think it fair to allow them the top solution utilizing it:
-65821=-9403x7


Thank you Nis,
In your solution 12. Record Score there were forbidden passes, which reduced your result.

The result -65821 would be minimal, but it was necessary to strive for the maximum.

Hello,

Sorry, but it seems my answer for problem 12 is not counted.
Sincerely,
Christian

Indeed, and indeed.
I also see that I had errors in 2 of the regular puzzles. Bummer.
It does seem like some scores are missing for puzzle 10 (including mine) - not sure if this is also due to invalidity of the answers? Seems unlikely, since "moeve" submitted what looks like the same solution as me, modulo reflection, and scored 8 points for it
Anyway: Thank you, once again.

Hello Christian,
It is noted on my sheet that you have 5 points. Sorry, we'll add it now.

I checked the table with my sheet. Some points were not saved. I'll ask Deb to add them.
P10:
Jo97 11 points,
Nizz 8,
Ausmunchkin 5,
Tiralmo 2 (Tiralmo confused the setting digits horizontally and vertically, but I counted him 2 points).
P11:
Sugitakukun 11,
Christian 5.

Thanks!

Thank you Riad, that was a great contest!
All the optimizers were interesting, and I think that the LMI-Road puzzle has a good new logic idea.
