A General Logic for Sudoku Rank 0 Double Loops |
|
Points. Any logic with equal numbers of non-operlapping
sets and linksets eliminates all candidates in its linksets. Rank 0 Double
This rank 0 double loop is covered by the first rule
of Sudoku set theory that says any logic with equal numbers of sets and linksets
will eliminate all candidates in all its linksets, if no sets overlap. The
logic has 5 sets covered by 5 linksets, all of which are rank 0 (highlighted
black). The 2 eliminated candidates (orange) are in row set r77.
Rank 0 Double Loop, Example 2
In this second rank 0
example, the eliminated digit 4 sits in box set b44. All
linksets must be rank 0, linkssets are not
highlighted.
