Wang tiles solver
A simple Wang-tiles solver.
You can represent the tiles as a tree. You start at the root node and try to fit a Tile into this spot. If you succeed, you move to a deeper node, if you can’t find a tile that matches, you move up in the tree.
At the end you either end up reset this node to 0 and move up.at a
h levels deep, or at the root
node with no more possible tiles to fit here.
