A high-performance C++ Sudoku solver implementing Knuth's Dancing Links (DLX) algorithm — one of the fastest exact cover algorithms in the world.

Features

  • Dancing Links (DLX) Algorithm: Implements Donald Knuth's Algorithm X with Dancing Links, renowned as one of the most efficient algorithms for solving exact cover problems
  • Blazing Fast: Solves even the hardest Sudoku puzzles in microseconds
  • Multiple Solutions: Can find all possible solutions or limit the search to a specified number
  • Optimized Search: Uses column selection heuristic (minimum size) for improved performance
  • Any Grid Size: Supports puzzles of any size — 4×4, 9×9, 16×16, 25×25, and beyond (size must be a perfect square)
  • Runtime Configuration: Grid size is configurable at runtime, not compile-time
  • Any Difficulty: Solves puzzles of any complexity, from simple to world's hardest
  • C++11 Standard: Written in modern C++ with smart pointers and RAII principles
  • Exception Safe: Proper input validation with descriptive error messages
  • Input Validation: Validates puzzle dimensions and grid size constraints
