The generator in mine is really not good. It solves an empty sudoku - the solver will pick randomly when it cant see a place with only one solution so the result is a random sudoku, then the system will repeatedly try to remove a random slot from the sudoku and tests whether it is still uniquely solvable*. It sort of popped out of the code as a solver benchmark, not as a proper generator.
Still the source code is included in the pnd, so if you want to see some bad bruteforce sudoku generation, go ahead and unsquashfs it.
* Actually solvable without ever needing to make a (random) choice - I'm not sure if that is the same thing, maybe.
