A word square is a puzzle that involves arranging words in a grid so that they're the same horizontally and vertically. Finding a perfect 10-word square in English has been an open problem for over a century. This repository provides a solution to this problem using a novel algorithm that significantly reduces the search space. For more information about the algorithm and the solution, see the publication and code in the repository.
