Zendoku puzzle generation
The strategy we picked was generate-and-test. This uses two algorithms: a generator which produces, in an unguided fashion, sudoku puzzles of unknown difficulty; and a grader, which works out how difficult each puzzle is. If a puzzle is the wrong difficulty we throw it away and generate another candidate.
there’s a clever way of implementing the algorithm which allows choices that are ruled out by the constraints to be quickly eliminated, and quickly put in again when backtracking.
