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 |
