A program here Minlex Routine reliably and quickly sorts minlex puzzles [ without the bug which plagued earlier programs]

Although the minlex program does handle a few million puzzles in a few seconds ... but it need a very clean string [ no gaps or line ender e.g]

I converted swb01's VB program to C last year, and removed the 83 line length restriction. I've now extended the sudoku line length limit to about 160 chars.
This minlex.exe can be dowloaded here: https://github.com/1to9only/swb01-s-minlex--single-program--MinLexDriver.exe/releases/tag/2026.4.27
I've also switched to using this program.

Very good.... im able to use this program...its incredible that it works so quickly !!!
Its great that you two have come on board with this exercise ! ...
If ever anyone [else] wants to generate puzzles I use "Sudoku Architect" available in the software section.
I only say this because the MAX exercise is going to need more contributors. !!!
Well done so far...
