libsudoku
A Sudoku generating and solving library.
Synopsis
Generates, validates and solves 9x9 Sudoku puzzles. It uses the Dancing Links implementation of Knuth's Algorithm X, which is a fancy use of doubly-linked lists to efficiently add and remove elements while preserving their original order. Given the small set of possibilities for Sudoku it is overkill compared to the naive brute-force algorithm, but nonetheless an interesting and efficient approach for the generalized NP-complete problem.
Building
The library itself (SudokuLib/*) should be portable, but the build system (Makefiles) assumes you're on some kind of POSIX system. The tests, especially, are only set up to build on Linux & OS X.
The typical make targets work:
- all
- test
- clean
Output
