4.4. Non-Solvable Deals
-
Adrian Ettlinger sent me a few layouts he tested, with fewer Freecells
than usual, that Freecell Solver could not solve.
-
I realized that the reason Freecell Solver could not solve them was that
a meta-move moved two cards in the opposite manner that would allow
for a solution.
-
The only way I could think of to solve this without messing my code completely
would be to code move functions that would simply perform atomic moves.
-
It was not done, yet.
