Loading Pencilmark grids into Sukaku explainer (Test Puzzles)
Examples of correct and incorrect loading:
When loading the puzzle, Sukaku Explainer considers a cell uncovered (solved) if:
- The cell that has only a single candidate
- The candidate is not present in any of the 20-peer cells (the candidate is not present in any other cell sharing a row, column or box with our uncovered cell)
On the GUI (default settings), a solved (uncovered) cell will appear in black large font. A complete solution will result in having 81 uncovered (solved) cells and that is the target of Sukaku explainer solving pathway.
A covered (unsolved) cell would appear in the GUI (default settings) with a small grey font. These cells regardless of the number of candidates in them are considered unsolved and will be targeted by Sukaku explainer to advance the solution towards uncovering (solving) them all.
consider the following Pencimark grid:
+----------+----------+----------+
| 9 8 1 | 7 3 6 | 2 4 5 |
| 7 3 5 | 4 9 2 | 6 1 8 |
| 4 2 6 | 1 5 8 | 3 9 7 |
+----------+----------+----------+
| 1 4 2 | 6 8 5 | 7 3 9 |
| 3 6 7 | 9 4 1 | 5 8 2 |
| 8 5 9 | 3 2 7 | 4 6 1 |
+----------+----------+----------+
| 2 1 8 | 5 6 4 | 9 7 3 |
| 6 7 3 | 2 1 9 | 8 5 4 |
| 5 9 4 | 8 78 3 | 1 2 6 |
+----------+----------+----------+
The following is an image of how the above grid should load:
The cells with small grey numbers are considered covered (Unsolved) cells and the cells with Big black numbers are considered uncovered (solved) cells, Sukaku explainer will target the unsolved cells in an attempt to advance to complete resolution where all cells are uncovered (solved).
The correct action that would follow if the grid was loaded correctly is r4c5 single. This can be illustrated in the next image:
The above image illustrates that all cells are uncovered (solved). This is shows a complete resolution (solution) and therefore Sukaku explainer will not take any further action and reports that the puzzle is solved
The above image illustrates another example of incorrect loading where r4c5 and r9c4 are considered uncovered (solved) therefore clearing 8 in r9c5 leaving r9c5 as the only covered (unsolved) cell remaining. The following would be Sukaku explainers next solving step:
Where it targets that covered (unsolved) cell and reports a single in r9c5
The next image illustrates the failure of identifying uncovered (solved cells):
All cells appear in grey showing that we have 81 covered (unsolved) cells. The Sukaku explainer next solving step would be:
where is it goes for single in r1c3
The following puzzle should have a rating of 12.0/12.0/11.8
