Beyond Sudoku: Exploring Constraint Satisfaction Puzzles
Sudoku is just the beginning. Let’s explore variants that push the boundaries of logic puzzles.
Killer Sudoku
Combine Sudoku with Kakuro - cages show sums, but no digit repeats within a cage.
Sandwich Sudoku
The numbers outside show the sum of digits between 1 and 9 in that row/column. Simple rule, complex implications!
The Algorithm Connection
These puzzles are constraint satisfaction problems. Techniques like arc consistency and backtracking with constraint propagation solve them efficiently.
