| Topic | What is this Sudoku voodoo? |
| Sahuagin 09/14/21 12:38:11 AM #6: | if you didn't add the lines, that's probably just the scanning path I think it's basically saying that you can split the 4s into the two groups, yellow and green. the 4s knock each other out, and if you split them apart based on collisions, you end up with two groups. somehow, if you do that, the yellow group still ends up with a collision but the green group does not, so the yellow group can be cancelled. I have not used that approach before, but have definitely seen the pattern of "either this set of numbers wins, or this set of numbers wins, but there's no evidence to choose one over the other" like a million times. I just don't know how they determine that those two 4s both belong in the same group despite colliding. and why wouldn't the colliding 4 just make a new third group by itself? I think I get it; it inverts across each line. each line says: there is exactly 1 other 4 in this set, so that is a true dichotomy, and the other 4 can be colored opposite of me. if you do this, and yet there is still a collision somewhere between digits of the same color (polarity might be a better term), then that color/polarity is invalid and loses. note that (I think) the line at the bottom is a separate attempted coloring that came up inconclusive, since no collisions were present after following the links. --- ...
