Note that empty (unsolved) positions are saved as well. + + The CLEAR button will clear any previously entered numbers. + + The STEP button can be used to solve the puzzle. If clicked, the program + will verify each empty cell. If a unique solution can be found for a cell, + it will be added to the solution. You will probably need to click STEP + several times to completely solve a puzzle. + +LIMITATIONS + + The current solving algorithm will only find a complete solution as long + as there are cells for which a unique solution through elimination can be found. + It cannot perform an exhautive search if the sudoko contains only cells for + which at least 2 solutions can be found. + COPYRIGHT This sudoku solver was written by Stijn "Ingar" Buys and is available under - the terms and conditions of the GNU Public License (GPL) + the terms and conditions of the GNU Public License (GPL). ingar@telenet.be htpt://ingar.satgnu.net diff --git a/examples/metro-2012-06-01.sudoku b/examples/metro-2012-06-01.sudoku new file mode 100644 index 0000000..d85432b --- /dev/null +++ b/examples/metro-2012-06-01.sudoku @@ -0,0 +1,11 @@ +0 8 0 1 9 2 0 0 5 +0 0 6 4 0 0 0 8 0 +3 0 0 0 0 0 0 2 0 + +0 0 0 6 0 0 0 0 9 +5 0 0 0 0 0 7 0 8 +0 0 9 0 3 0 4 0 0 + +0 0 7 8 4 1 0 0 0 +1 6 5 2 7 0 0 0 0 +4 0 0 3 0 0 2 0 0 diff --git a/examples/metro-2012-06-04.sudoku b/examples/metro-2012-06-04.sudoku new file mode 100644 index 0000000..5cf44f6 --- /dev/null +++ b/examples/metro-2012-06-04.sudoku @@ -0,0 +1,11 @@ +0 2 1 0 0 0 8 0 0 +0 0 6 0 5 0 3 0 2 +8 7 3 0 0 0 0 1 0 + +2 0 0 5 0 4 7 0 0 +0 6 0 0 0 3 5 9 8 +0 0 7 6 8 0 0 0 0 + +0 0 9 0 4 0 0 2 0 +3 0 0 0 0 6 0 5 0 +0 0 0 0 0 9 0 0 7 diff --git a/examples/metro-2012-06-08.sudoku b/examples/metro-2012-06-08.sudoku new file mode 100644 index 0000000..6b97a3c --- /dev/null +++ b/examples/metro-2012-06-08.sudoku @@ -0,0 +1,11 @@ +0 0 0 0 5 9 0 7 6 +8 0 0 4 0 6 0 0 0 +6 0 0 0 0 0 8 0 9 + +5 2 3 0 0 0 7 9 0 +0 7 6 5 0 0 0 0 2 +0 0 0 0 0 7 3 0 0 + +2 6 4 3 0 0 0 0 0 +3 0 0 0 2 0 0 1 4 +0 0 1 9 0 0 0 8 0 diff --git a/examples/metro-2012-06-15.sudoku b/examples/metro-2012-06-15.sudoku new file mode 100644 index 0000000..2504f4c --- /dev/null +++ b/examples/metro-2012-06-15.sudoku @@ -0,0 +1,11 @@ +0 0 0 0 4 0 6 1 0 +0 1 0 8 0 0 2 0 0 +9 0 0 2 0 0 0 5 7 + +3 0 0 4 0 1 0 0 0 +0 9 0 6 7 0 0 3 8 +0 0 5 3 0 0 0 2 0 + +0 5 8 0 0 6 4 0 0 +0 0 9 1 0 0 0 0 0 +6 3 1 0 9 0 7 0 0 |
