Hi guys!

After some polishing the updated Grayout program is completed. Now always solvable becuase the available number of steps are given by a new non optimized algorithm. In most cases you can probably beat that algorithm. I hope this will be the final version but one never knows what new issues may come up.

The Linux (Debian) version can be downloaded from:
