| Dec 20, 2016 at 2:52 | comment | added | guthrie | @yo - no, no no - "trying a bunch of things" without an underlying logic to guide the choice, is guessing. Your example of "considering all possible values for a cell" is an interesting example, and although this starts to be just semantics, I would say if you commit to one of them without a logical basis and try to then make it a solution, yes, =guessing. Just looking at each possibility to see if there is some logic for it = not-guessing. | |
| Dec 19, 2016 at 20:19 | comment | added | yo' | @guthrie Sorry, no, no and no. There are people who can consider a chess game 8 moves forward or so. I'm quite sure that if these people concentrated on sudoku rather than on chess, they would not say they are "guessing". You could equally say that at one moment you try all numbers 1,2,3,...,9 into one cell to find out that only 7 fits in -- does this make all standard sudoku methods "guessing"? | |
