Thanks for your suggestion.
I think that, instead of modifying solver.ex, it would be better to write
a new given1.ex program that gets the input in the format you suggest and
writes it out in the format solver.ex uses. I will add this program in the
next version, but before I will wait until more feedback comes.
Also, somebody in the list might want to port the algorithm to a visual
environment. At the present time, I have no time for this.
Writing this program was only a relaxing interlude between activities
that raise funds...
