| # Visual Sudoku preprocessing | |
| # Generation parameters are hardcoded in SudokuPreprocessor to avoid extra | |
| # DatasetConfig fields. Current values: | |
| # n_clues_start = 55 (start with 55 random clues — almost always unique) | |
| # max_removals = 10 (remove up to 10 clues while preserving uniqueness) | |
| # Result: ~45 clues per board, all uniquely solvable, no warnings. | |
| # For publication: increase max_removals to get true minimal puzzles (~25–35 clues). | |
