Dancing Links (DLX) Sudoku solver at Artificial Intelligence (slo. Umetna Inteligenca).

Solves Sudoku using dancing links technique, an efficient implementation of Algorithm X, as suggested by Donald Knuth. Supports all NxN sizes where N is a perfect square (4x4, 9x9, 16x16 ...).

Thanks to KarlHajal/DLX-Sudoku-Solver for a high-performance C-like implementation that served as the most important reference for this implementation. Additional thanks to Jonathan Chu's Java Sudoku Solver and paper for another important reference.
