module Doku::DancingLinks
This module contains a general-purpose implementation of the {arxiv.org/abs/cs/0011047 Dancing Links} algorithm discovered by Donald Knuth for solving {en.wikipedia.org/wiki/Exact_cover exact cover problems}. This module is included in the Doku
gem for convenience, but it is not specifically for solving Sudoku-like puzzles; it can be applied to any exact cover problem. The main class in this module is {LinkMatrix}. All the other classes and modules are helpers for this class.
