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. :D

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...

Had a quick stab at MAX, and found this immediately. Perhaps more tomorrow.
